In addition to any calendars you create in your Fastmail calendar, you'll also see a special calendar called Birthdays. You can turn this on and off in the calendar view menu in the toolbar.
The Birthdays calendar is created automatically from birthdays listed in your contacts. It will show the birthdays of every person who has a day and a month of birth in their individual contact card.
For contacts with a specified year of birth, events will display the age they will be turning on that day.
Because this calendar is created based your contacts, it is not a calendar that is associated with CalDAV. If you're syncing your calendars via CalDAV, it is expected behavior for the Birthdays calendar not to sync.

For example, you can keep mail from your team in one section, newsletters in another, and everything else below.
You can group your Inbox, any other folder or label, and any saved search. The grouping you choose will stay consistent across different devices or logged in sessions.
The grouped mail view feature is available to customers on all subscription plans.
To group a folder, label, or saved search:
Three groupings are ready to use:
Custom groups let you decide exactly how your mail is split. Each group is a search, and every conversation that matches goes into that group.
To create a custom group:
From here you can select from our suggested groups, or write your own group search:
We suggest these options, which cover the most common ways to group mail:
After following the steps above:
Searches here use the same search operators you use when searching your mail. Some examples:
| Search | \nWhat it groups | \n
|---|---|
from:@example.com | \nHigh-volume notifications from one sender domain | \n
list:list.example.com | \nEverything from one mailing list | \n
to:alias@example.com | \nMail sent to a shared alias | \n
subject:invoice OR subject:receipt | \nPurchases and receipts | \n
You can combine operators with AND, OR, and NOT to make a group as narrow or as broad as you need. See Searching your mail for the full list of operators.
Searches here can't search message bodies, so a plain word on its own, like meeting, won't work as a group. Use an operator instead, such as subject:meeting.
If a search query includes something that won't work, we'll let you know which part to change before you save.
To reorder groups:
Note that if a conversation matches more than one group, it appears in the first group that matches.
To rename a group or change a search query:
To delete a group:
To go back to an ungrouped view:
Groups are set separately for each folder, label, and saved search. That means you can split your Inbox into work, notifications, and everything else, while your saved search is grouped by age and your Archive isn't grouped at all.
To set up groups elsewhere, open that folder, label, or saved search and choose Group from the More menu (⋯), just as you would in your Inbox.
Each section has a header showing its name and how many conversations it holds.
Groups only change how your message list is laid out. Folder unread counts, badges, and notifications work exactly as before.
Grouping works whether you have conversations on or off. With conversations on, each conversation is placed in a group as a whole; with conversations off, each message is placed in a group individually.
With keyboard shortcuts turned on, you can jump between groups without touching the mouse:
| Shortcut | \nAction | \n
|---|---|
\nShift J\n | \nNext group (down) | \n
\nShift K\n | \nPrevious group (up) | \n
The usual J and K still move between conversations within a group, just as when grouping is not enabled.
Let's say you send an email, only to have the recipient discover it hours later in their Spam folder.
Spam filtering is performed by email providers to protect their recipients from unsolicited or malicious emails. No spam filters are perfect, and they may cause your legitimate email to be marked as spam.
It's often difficult to know why a message was filtered as spam. In this help page, we'll cover the most common scenarios that might cause an email to be marked as spam on the recipient's side.
Sending bulk mail can increase the chances of your messages being marked as spam. Email providers sometimes apply stricter requirements for bulk senders, so it is generally better to use a dedicated bulk mailing service.
If your workflow involves sending marketing, newsletter, transactional, or notification emails, we ask that you please use a service dedicated to bulk mailing. Sending bulk emails is not permitted under our Terms of Service.
One of the factors an email provider considers while deciding whether an email is spam is its content. Excessive use of words seen in promotional emails, links to websites or domains with a poor reputation, and signatures containing multiple links are some of the common reasons why an email may be marked as spam.
If you suspect that your email's content may be considered suspicious, you can test this by sending a plain-text email with a short sentence. If the email doesn’t go to the recipient's spam folder, the problem is almost certainly the content of the email you sent earlier.
Email authentication is a set of protocols that verifies the legitimacy of the email sender, helping to control and recognize email spoofing. It uses existing standards like SPF, DKIM, and DMARC to confirm that an email is genuinely from a sender authorized to use the domain it claims to be from. If the domain has not been properly set up, mail providers may mark your email as spam.
If you're using a Fastmail domain, we will take care of the necessary DNS records to have the email sent out with proper authentication.
If you're sending emails from a custom domain, make sure that your domain's DNS records are configured correctly to send emails. You can check if the SPF and DKIM configurations are correct by opening your domain from the Settings → Domains screen.
The recipient’s email provider may mark an email as spam if it is coming from a domain with a low reputation. If your domain is newly registered, this can cause it to be considered low reputation. Your domain could also have a low reputation if it has been reported for spam too many times, or if it is on a blacklist.
If you suspect that your domain’s reputation is causing the issue, you can test this by sending the same email again, but this time from an alias at a Fastmail domain instead of your custom domain. If the email doesn't go to the recipient's spam folder, the problem is likely the domain's reputation.
If you notice that emails addressed to only a particular email provider are being marked as spam (e.g. every message you send to someone using Outlook goes to their spam folder), it usually indicates that the domain has been blacklisted by that email provider.
It may be helpful to ask your contacts who use the same email provider to mark your emails as \"not spam,\" which could help increase the reputation of your domain at that provider.
If your emails are only being filtered as spam when sent to a specific person, it could be caused by a specific rule, setting, or filter on that recipient's account. You can ask the recipient to:
If you’re unable to narrow down the issue, ask the recipient for the full headers of the email that was marked as spam. These headers may contain information about why an email was marked as spam.
Contact our support team with these headers and the details of the troubleshooting steps you’ve already performed, and we can look into this further.

Please see our Pricing page for a complete comparison of the features and differences between all Fastmail plans.
Every Fastmail account starts on a 30-day trial at signup, so you can try out Fastmail for 30 days before you need to choose a plan. You can sign up for a trial account here.
If you're not sure which plan is right for you, this guide can help. The best choice for you will depend on factors such as how many users you need, how much storage your users need, and which features those users need.
We offer Individual, Duo, and Family plans for personal use:
All of the above plans offer 50 GB of mail storage and 10 GB of files storage per user, as well as standard-level features including custom domains, use of third-party mail clients or apps, and productivity features like Snooze or Scheduled Send.
If you're using Fastmail on your own and you don't need a lot of storage or features, we also offer a Basic plan, which is a no-frills plan designed for light usage. The Basic plan provides 5 GB of mail storage and does not include custom domains, use of third-party mail clients or apps, or productivity features.
Business accounts allow you to pay per user and choose the plan that best fits each person's needs. You can mix and match plans within the same account, so not every user needs to be on the same plan (i.e., some employees can use Business Basic, while others use Business Standard or Business Professional).
We offer Business Basic, Business Standard, and Business Professional for companies and organizations.
Note: With a multi-user Business account, you only need one admin on a Standard or Professional plan to share a custom domain with Basic users.
For more information on how a multi-user plan works, please see our Managing multi-user accounts help page.
The difference between Personal and Business plans becomes especially important when you need to add multiple users.
Duo and Family plans can be a good value for personal use when everyone needs similar features. Business plans offer more flexibility for organizations, including the ability to mix and match plans based on each user's requirements.
When choosing a plan, consider how many users you need and which features each person requires. You should also consider the limits that apply to each plan, such as storage, aliases, domains, and sending and receiving limits. For detailed information, see our Account limits help page.
You are welcome to change your subscription plan at any time. Information on changing your plan can be found on our Upgrade or downgrade your subscription plan help page.
If you need help choosing or changing your plan, please reach out to our support team and they'll be happy to assist.

The good news is that, in many cases, your account hasn’t been compromised and the email is spoofed.
This help page explains what email spoofing is, how to tell if it happened, and what you can do about it.
Email spoofing is when someone sends an email that is made to appear as though it came from a different address or sender than it actually did, often a trusted sender, organization, or even your own email address. Attackers use spoofing to trick recipients into trusting a message or to bypass spam filters.
Spoofing is possible because the addresses you see in the To and From fields are simply part of the message content, they do not determine delivery. For example, forwarded emails maintain the original To and From while the sender (the person who forwarded the email to you) and recipient (you) are different. Behind the scenes, email is routed using separate “envelope” addresses.
Since the email system was originally designed for communication between trusted devices, To and From fields can be forged or spoofed. The Email addressing help page has more detailed information about this process.
Modern sender authentication tools can help in identifying when an email has been spoofed.
We use Sender authentication standards like SPF, DKIM, DMARC, and ARC to help verify that an email really came from who it claims to. SPF checks whether the sending server is allowed to send for that domain, DKIM uses cryptographic signatures so receivers can tell if the message was tampered with. DMARC builds on these by checking against the domain in the header “From” (the part that is most commonly spoofed), and by letting domain owners specify how SPF and DKIM failures should be handled.
Fastmail treats authentication results as a signal and not a cause to block emails because sender authentication can fail for legitimate reasons such as email forwarding. Not all authentication failures indicate a spoofed or malicious message. When an email fails authentication, spam scores are adjusted to reflect this. However, authentication is only one of many factors used to determine whether a message is delivered to the Inbox or Spam.
You can view the headers of an email by clicking the Actions menu at the top right of the message, then clicking Show raw message.
If the header X-ME-Sender is present and contains xms information, the email was sent from Fastmail servers which means the email was not spoofed. If you see this header on an email with your address in the “From” header and you did not send this email, please reach out to our support team for assistance.
If you receive a spoofed message, you can report it as spam by selecting the message, clicking the More button, and clicking Report spam.
If you are using a custom domain and you’re seeing frequent spoofing attempts, we recommend setting up a DMARC policy. This tells receiving mail servers how to handle unauthenticated emails sent from your domain.

An MCP server allows different services to connect with AI applications.
Fastmail has an MCP server that you can use to connect an AI tool to your Fastmail account, such as Claude Desktop, ChatGPT, or Perplexity. At this time, Fastmail does not offer direct integrations with any AI tools.
Use of an MCP server is optional, and is intended for customers who are expressly interested in using AI tools with their Fastmail account. For more information on our approach regarding MCP, please see our blog post.
You can use Fastmail's MCP server to connect your Fastmail account to any AI client that supports MCP and allows you to use an external server.
Depending on how you'd like to use the AI client with your Fastmail account, you can choose some or all of the following levels of access:
Below are some examples of ways you could prompt an AI client to interact with your Fastmail account.
If you grant read-only access:
If you grant write access:

https://api.fastmail.com/mcp\nThe exact steps for setup will differ depending on the AI client you're using. If you need assistance finding the documentation for your AI client, please feel free to reach out to our support team, and we can guide you in the right direction.
Below are instructions for connecting Fastmail to Claude, one of the most commonly used AI clients.
Please note that Claude does not support adding multiple Fastmail accounts. This may be supported by other AI clients, including ChatGPT.
Once an AI client has been successfully connected to your Fastmail account, the AI client will be listed as an app under Settings → Privacy & Security → Connected apps.
You can review the AI client's access details at any time, which include the following:
To review an AI client's access details:
You can remove the AI client's access at any time. To remove it:
When you connect an AI client to your Fastmail account, any data that the AI client accesses (such as emails, calendar events, or contacts) is subject to that provider's own privacy policy and data handling practices.
Fastmail has no control over how connected AI clients store, process, or use your data. Before connecting an AI client, we recommend reviewing its privacy policy.
Depending on your profession or location, connecting your email to a third-party AI client may have legal or compliance implications.
If your email contains sensitive, confidential, or regulated information — such as health records, legal communications, or personal data belonging to others — you should seek appropriate advice before connecting an AI client to your account.

It's recommended to make Safari your default browser for this installation. You can change the default browser to another one of your choice afterwards.
Did you know? Fastmail has an excellent iOS app which many of our users prefer to other mail apps. See our mobile app help for more details.
Third-party apps need their own app password to access your information. If you use your normal password or your Fastmail two step verification password on an external account, syncing to an external service won't work and you will see a password error.
You can easily set up your device and avoid a lot of manual typing using our setup tools: either scan a QR code that sets everything up, or set up via a mobile web browser.
Please note that the automatic setup tool may not work if you have Lockdown mode enabled.
Note: Selecting contacts/CardDAV will sync all CardDAV accounts by default (both personal and shared). If you want to sync them separately, manually create individual CardDAV accounts.
As a general note, if you want to send from addresses other than your Fastmail username, you will need to set up your Fastmail account on iOS manually instead of using our automatic setup tools. However, if your Fastmail account uses a different alias as its default address, the configuration profile will use this when composing emails instead of your username.
If you have another device nearby, you can use your camera to scan a QR code and automatically set up your Fastmail account. (Please note that the QR code will not appear if you have multiple addresses.)
The screen will show a QR code.
Tap Allow to download the configuration file.
\nInstall the configuration profile: Tap Settings, then Profile Downloaded, then Install. Note: For iPad devices, after Settings, you may need to tap More for Your iPad before you get to Profile Downloaded.
\n\n
Setting up via mobile web browser
You can use the mobile browser on your device to perform a one time automatic setup.
The screen will show a link to a configuration file to install a new profile. Click Open this configuration file.
Allow the browser to open Settings to show a configuration profile.
\nInstall the configuration profile. This will automatically set up your mail, calendar and contact settings on your device, according to the access types you requested for this app password.
\nAdding other accounts to send with on iOS.
Enable the Notes option.
\nYou can now verify it's working in the Notes application.
You will now see a list of places where your notes are stored, and you can select which set of notes you want to view.
\nIf you'd like to use Fastmail storage as the default location for new notes to ensure they are backed up and always available:
Choose your Fastmail username as your default account.
\nIf your notes do not display, check the advanced server settings.
If you change an iPhone app password after adding your Fastmail account to your iOS device, you will need to update the settings on your device. The easiest way is to delete the old profile off your device and use the automatic setup tool to generate a new password and store it on your phone.
To set up the app passwords for email, calendar, contacts and notes manually, we have detailed instructions. This is not the preferred way, as it is more prone to human error.
To delete Fastmail from your iOS device, you need to remove the profile.
This will remove Fastmail from the list of internet accounts on that device.
It is possible to individually disable each mail, contact or calendar account in the iOS settings, but to delete them, you have to remove the profile.

You can also open the composer in a new window by holding the Shift key and clicking Compose or Reply.
For more information on using the pop-out composer, please see our Open messages in a new window help page.
By default, the reply options you see on a message will depend on the recipients:
If you are viewing a conversation and you only want to respond to an individual sender, click the Actions button in the message and select Reply to sender.
If you have already started drafting a message, you can click Reply to ___ in the composer and select the desired reply option.
If you prefer to have your replies go to the sender by default, this can be changed under Settings → Mail preferences (see \"Replying in a conversation\" on the Conversations help page for more).
When replying to a message in the web interface or desktop app, the compose window will appear inline within the conversation thread, allowing you to scroll up and reference the conversation if needed. Composer buttons (Send, Attach, Discard, etc.) will be shown along the bottom of the composer.
The subject line is hidden when replying inline to provide more space for writing your message. If you need to edit the subject line, you can do so by clicking the More button on the bottom toolbar, then clicking Edit subject. (Note: We generally do not advise changing a subject line on a reply, as this breaks conversation threading.)
If you prefer to compose replies in a focused view (similar to the normal compose window), you can switch to the focused view by clicking the icon that looks like two arrows:
When replying in focused view, the composer buttons will be located at the top of the composer, and the subject line will always be shown.
If you switch to focused view, this preference will be saved locally.
A message can be sent to one recipient or multiple recipients.
Recipients can be added to the To field, Cc field, and/or the Bcc field. Clicking Cc and Bcc will display the Cc and Bcc fields, and you can click Hide to remove them. Recipients added to the Cc field will be carbon copied, and recipients added to the Bcc field will be blind carbon copied.
After adding a recipient, you can drag and drop them between To, Cc, and Bcc as needed. If you want to select more than one recipient at a time, you can use Ctrl + Click to select individual recipients, or Shift + Click to select a range of recipients. You can also right-click the recipient to show a menu where you can quickly add them as a contact, or view their contact information if they have already been added to your addressbook.
There are different actions that can be taken on a message. These are found on the composer toolbar, and include the Send, Save draft, and Discard actions.
Click Send to send your message to the intended recipients. There is also the Scheduled Send option, which can be accessed by clicking on the down arrow that is on the right side of Send. This is used for scheduling a later time in which your message will be sent out. For more details, see the Scheduled Send help page.
Click Save draft to save the message you're currently composing as a draft. For more details, see the Drafts help page.
Click Discard to delete the message you're currently composing.
The More button in the composer toolbar shows extra options that you can enable for your message:
More details on the high priority and read receipt options can be found in the Read receipts help page.
There are various options available for formatting your messages in the composer. For a more detailed explanation of the formatting options, please see the Add formatting to emails help page.

With the Fastmail desktop app, you can open Fastmail in its own window, separate from your web browser. Launch Fastmail directly from your dock or taskbar and find it in your platform’s app switcher.
You can download the desktop app here.
Navigation in the desktop app generally matches navigation in the web interface.
Some differences may be visible in the top toolbar:
The desktop app also follows the same keyboard shortcuts as the web interface. A full list of available keyboard shortcuts is available here.
Our desktop app offers full offline support. This means that even if you're not connected to the Internet, you can still read your mail, write replies, manage your calendar, and so on.
If you've made any changes in the desktop app while offline, the changes will sync as soon as you reconnect to the Internet.
The Sync status icon indicates whether the app is currently fully synced, in the process of syncing, or offline.
For more information, please see our Offline support help page.
The Fastmail desktop app can be run on the following OS versions:
We also offer a beta version of the desktop app, which is available for download here.

If you'd like to be able to access your mail while offline, you will first need to enable offline support for your device or browser (see Enable offline support below).
If you do not have offline support enabled, it is expected behavior to see a \"Could not connect to server\" banner over a loading screen when attempting to access Fastmail offline.
You can enable offline support for your device by going to Settings → Offline and clicking the toggle button next to Enable offline support.
We'll start downloading mail to your device so that it can be available for offline access. You can choose whether you'd like us to cache only recent mail (any message that has previously been viewed on this device, plus any future messages you receive) or if you'd like us to cache all mail (every message that's in your account).
The mobile app will need to stay open and active (not running in the background) while the device is syncing. Syncing on your browser can happen in the background.
Note: If you see a banner on the Settings → Offline screen that says \"Long-term session required,\" this means that you will need to log out, then log back in with the Keep me logged in option enabled. Once you are logged in with Keep me logged in selected, you should then be able to return to the Settings → Offline screen and enable offline support.
You can disable offline support for your device by going to Settings → Offline and clicking the toggle button next to Disable offline support, then selecting Confirm.
Disabling offline support will remove the cached data that we previously downloaded to your device while offline support was enabled.
While offline, certain features may not be available or may behave differently.
Mail search will only work on messages that have been cached offline.
Mail search cannot search inside attachments while offline.
Stemming is not used to match phrases while offline, which means that we won't automatically include plurals (fox, foxes) and tenses (fish, fishing, fished) in search results as we normally would. Offline mail search will instead use prefix matching, which means that when you search for a phrase, we will include any words that include that phrase at the beginning (e.g., searching fox would match \"fox\", \"foxes\", \"foxtrot\", etc.).
If you're offline when a snoozed message is scheduled to return to your Inbox, you will not see the snoozed message reappear until you're back online.
You will not receive calendar reminder notifications while offline.
Attachments are only cached for offline use when opened on the device.
Attachments cannot be deleted from messages while offline.
You cannot make the following changes to your Fastmail account while offline:

If you are looking for general information about migrating from Pobox to Fastmail, please see our Guide to Fastmail for Pobox users help page.
If you are having trouble logging in, please check to make sure that you are logging in at app.fastmail.com and entering the correct username.
Your username should be the same as your Pobox reference address. Please be sure that you are entering the full email address, including the domain, into the login form. As an example, if your username is myaddress@domain.com, you will need to enter myaddress@domain.com instead of only typing myaddress.
If you have forgotten your username or password, or if you have lost your 2FA device, you can use our account recovery tool to regain access to your account.
We strongly recommend setting up a recovery email address and/or phone number in case you ever need to use the account recovery tool. You can set up recovery options by going to the Settings → Privacy & Security screen, finding the Account recovery section, and clicking Add recovery options. For more information on adding recovery options, please see our Passwords help page.
For more in-depth information on this problem, please see our I can't log in! help page.

For a complete guide that will walk you through troubleshooting this problem, please see our I'm unable to receive mail! help page.
If you see a warning in the Fastmail web interface that says \"Send failed! Sorry, you can't send messages at this time,\" this means that we've detected bulk sending from your account. Fastmail is not designed for bulk sending, and our Terms of Service prohibits sending duplicative email. You will need to contact our support team to discuss next steps.
If you are having trouble sending from a mail client, please check that your SMTP settings are correct.
If you are unable to find the cause of your problem, you may be able to find the information you’re looking for by searching Fastmail’s comprehensive Help Center.
If you would like assistance, please submit a ticket through our support form and our support team will be happy to look into this for you.

\nPasskeys are considered more secure than passwords because they are cryptographic key pairs that are bound to a specific domain. This reduces the risk of phishing, as there is no password used and the passkey cannot be used on a fake website. Since there is no password to remember, this also allows for faster sign-ins and helps you avoid password reuse.
\nFastmail is introducing passkeys as an alternate login mechanism — your Fastmail username and password will continue to work after a passkey has been created in your account.

\n\nIf you have never created a passkey in your Fastmail account, you can do so by following these steps:
\nAfter one passkey has been created in your Fastmail account, you can create any future passkeys by going to Settings → Privacy & Security and clicking Manage passkeys. From there, you can click Create a passkey and follow the above steps (starting from Step 3).
\nOnce you have created a passkey, you can use it to sign in at the Fastmail login screen.
\nIf you enter your username and we detect that your account has a passkey saved, we'll also show a button to begin the passkey sign-in flow. Once you have approved the sign-in using your device's password, biometrics, or PIN, you will be brought directly to your account's mailbox.
\nDepending on your password manager, you may be prompted to sign in with your passkey without needing to enter any credentials.
\nYou can view and manage your passkeys by going to Settings → Privacy & Security and clicking Manage passkeys.
\nFrom this screen, you will be able to see your passkeys listed from newest created to oldest created. You can see the passkey's name, when access was given, and when/where it was last used to access your Fastmail account.
\nIf you want to delete a passkey, click the Remove button. Note that when a passkey is deleted from your Fastmail account, your device/password manager will not be aware of this change — you will continue to be prompted to use the passkey at the login screen until you have manually removed it from your device/password manager.
\nTwo-factor authentication is based on the idea that you are authenticating using a combination of something you know (your password), plus something you have (the 2FA code supplied by your device).
\nPasskeys already combine something you know/are (your PIN, password, or biometrics), plus something you have (your device). For this reason, we do not prompt for 2FA when passkeys are used.

All Pobox customers have been migrated to Fastmail.
Fastmail is an email company founded in 1999 and headquartered in Melbourne, Australia. Pobox has been owned and operated by Fastmail since its acquisition from IC Group in 2015. Since this acquisition, Pobox has been able to provide better webmail and customer service, all because of the expertise and staffing available through Fastmail.
Your experience with Fastmail is brought to you by the same support agents and engineers you’ve enjoyed having on your side for many years, and we hope for many more years to come!
We’ve prioritized ensuring a smooth transition for all Pobox customers. Your mail will continue to be delivered, and your mail client setups do not need to change.
On this page, we will:
Every Pobox user received an email from us in October 2024. So that we can provide each user with the same high level of support, we sent this to a subset of customers each day.
If you have any questions or need assistance, you can contact Fastmail support anytime by sending an email to support@fastmail.com or submitting a ticket through our support form. Our support agents are knowledgeable about both Fastmail and Pobox, and will be happy to help you through this transition.
Below you’ll find what you can look forward to now that your account is migrated to Fastmail.
You will need to log in to your account through the Fastmail login screen at app.fastmail.com. You will be able to log in using your Pobox reference address.
If you experience any difficulty logging in, please see the \"Unable to log in\" section of our Troubleshooting Pobox migration problems help page.
Fastmail offers unique features to help you keep track of when and where you are logged in, such as a login log and remote logout. For more information, see our Logged in sessions help page.
Your Settings → Privacy & Security screen is where you'll find everything you need to keep your account secure.
If you need to change your password, you can go to the Settings → Privacy & Security screen, find the Password & Two-step verification section, and click Change password. For more information on changing your password, please see our Passwords help page.
The Settings → Privacy & Security screen is also where you can go to create an app password to set up a third-party email client or app (e.g., Outlook, Apple Mail, Thunderbird). For more information on this, please see the Mail client setup section below.
We strongly recommend having a recovery email address and/or phone number in case you ever forget your password and need to use our account recovery tool. If you already have a recovery phone number in your Pobox account, this will be automatically added as a recovery option in your Fastmail account.
If you'd like to add or change your recovery contact details, you can do so on the Settings → Privacy & Security screen: find the Account recovery section, then click Add recovery options. We recommend taking this step as soon as you are able to access your Fastmail account.
We also recommend setting up two-step verification (also known as 2FA) to increase the security of your account. For more information on using 2FA, please see our Using two-step verification (2FA) help page.
If you already have 2FA options set up in your Pobox account, these have been migrated to your Fastmail account, so you will be able to continue using them with no additional setup needed.
You can now store mail in your Fastmail mailbox, read your mail on the web via Fastmail's exceptional web interface, and use IMAP to sync mail with the mail client of your choice. Sent messages are saved in your Sent folder.
Your mailbox storage quota corresponds with your subscription plan. See the Subscriptions for migrated Pobox users help page for details.
Fastmail offers an intuitive webmail interface that comes with features to help you stay organized, productive, and secure.
You can choose to organize your mail in folders or switch to labels. You can also color code your folders or labels, and customize your entire user interface by choosing a theme.
Mail is threaded into conversations by default (i.e., replies are grouped with the original message).
For more information on navigating your mailbox, please see our Mail basics help section.
Your Pobox forwarding has been carried over to your Fastmail account. Messages sent to your Pobox aliases continue to be delivered to your forwarding addresses.
If you have been moved from a Pobox Basic or Pobox Plus plan, mail will be delivered to your forwarding addresses by default. Copies of your forwarded mail will be delivered to your Fastmail mailbox's Trash folder.
If you have been moved from a Pobox Mailstore plan, mail will be delivered to your forwarding addresses and your Fastmail mailbox.
Spam will not be delivered to external forwarding addresses. For more information, please see our Spam section below.
If you would like to set an alias to automatically forward all mail to an external email address (i.e., an address that is not set up in your Fastmail account), you can do this using the Deliver to another address option. For more information on setting this up, please see the Delivery options section of our How to set up aliases help page.
Anyone using a third-party email client or app (e.g., Outlook, Apple Mail, Thunderbird) prior to the migration should be able to use the same client—it should just work! No changes in server settings will be needed.
If you need to set up a new third-party email client or app, we recommend using Fastmail servers. We offer setup guides that can walk you through setting up your Fastmail account on various popular mail clients and apps.
When setting up a third-party email client or app, please note that all connections over third-party clients or apps need an app password to access your information. If you use your normal password or your Fastmail two-step verification password on an external client, syncing won't work and you will see a password error.
Our guides for several different mail clients and apps available in our Setting up mail clients help section.
We also offer built-in calendars, contacts, and notes, which can be easily synced with your devices.
Fastmail calendars allow you to keep track of upcoming events with ease. You can create events, send and respond to invitations, subscribe to public calendars, create shared calendars with other users in your account, and more.
With Fastmail contacts, you can add detailed entries to your address book, create VIP contacts that let you choose special settings for certain people, create a shared address book with other users in your account, or easily view contact information from your inbox using the sidebar.
Fastmail notes let you write, store, and easily access whatever information you need to stay organized.
Your Pobox invoice history is not available in the Fastmail billing interface.
You can pay for your account and manage your subscription plan through the Settings → Billing & Plan screen. From this screen, you will also be able to view your account's billing history and next renewal date.
Please note that billing is only handled by the administrators of your account. If you are not an administrator for your account, you may not see this screen available in your settings. Separate billing contacts cannot be added.
Your subscription renewal date remains the same. When you renew, payments will appear on your credit card or bank statement as \"Paddle.net* Fastmail.\"
For more information on billing, please see our Payments help page.
Each user has their own login credentials, mailbox, and storage quota.
If you want to add users to your account, you can do so by going to your Settings → Users & Sharing → User management screen.
If you are not an administrator for your account, you may not see this screen available in your settings.
For more information on adding and managing users, please see our Managing users as an admin help page.
For most customers, your Pobox aliases have been migrated to your Fastmail account, so you will still be able to use all of your addresses.
There may be some edge cases where we will not be able to migrate a Pobox alias (e.g., the alias uses a custom domain that belongs to a user in a different Fastmail account).
You can create new aliases by going to your Settings → My email addresses screen. For more information on navigating this screen, please see our My email addresses help page.
When setting up a new alias, you'll see that you can set up delivery and compose options. Delivery options control how you receive mail sent to this alias (e.g., automatically moving a message to a certain folder or forwarding it to another email address) and compose options control how you send mail from this alias (e.g., changing the name recipients will see). For more information on configuring aliases, please see our How to set up aliases help page.
We also support plus addressing and subdomain addressing, which allows you to easily use variations of your aliases and automatically file mail into folders. For more information, please see our Plus addressing and subdomain addressing help page.
You can set up an alias to deliver mail to the addresses of your choice using the Deliver to another address option. For more information on setting this up, please see the Delivery options section of our How to set up aliases help page.
Personal domains set up in your Pobox account have been migrated to your Fastmail account. Your domains will continue working with no DNS changes or additional setup needed.
If you purchased a domain through Pobox, its registration will move to Fastmail. Please look for an email from us with instructions on how to ensure a smooth transition.
You can view domains that have been added to your Fastmail account by going to your Settings → Domains screen. On this screen, you will be able to see whether your domain is active or inactive, and if any DNS changes are needed. (Domains moved from your Pobox account will be shown as active, with no changes needed.) If you are not an administrator for your account, you may not see this screen available in your settings.
You can set up aliases using your custom domains by going to your Settings → My email addresses screen.
You can also set up a catch-all alias at your domain, which allows you to receive mail to any address at the domain, even if it has not been set up as an alias yet. For more information on setting up a catch-all alias, please see our Catch-all/wildcard aliases help page.
If you had AllMail set up for a personal domain in Pobox, a catch-all address has been automatically created in Fastmail. If you set up any AllMail exclusions, these were migrated over as well.
If you have been moved to a Fastmail Lite or Fastmail Basic plan, please note that you will not be able to add any new custom domains through Fastmail. If you wish to add a new custom domain, you will need to upgrade to a Fastmail Standard or Fastmail Professional plan.
If you have been moved to a Fastmail Standard or Fastmail Professional plan, you can add new custom domains by going to Settings → Domains, clicking Add domain, and following the domain setup wizard. You can purchase a custom domain through a registrar of your choice, or you can register a domain through Fastmail.
We hope you'll love Fastmail's improved spam protection, eliminating the need to manually fine-tune your spam handling. Fastmail's spam protection does not support blocking messages per country, emailed spam reports, or the \"hold\"/\"release\" process for filtering spam.
Messages that we flag as spam will be delivered to the Spam folder in your Fastmail mailbox, and will not be sent to your forwarding addresses.
If a legitimate message is caught in your Spam folder, you can use the Not spam button to mark it as such.
Upon marking a message as not spam, we'll check to see if your account has any mail rules or email address actions that should be applied to this message. We will apply any rules that would move the message to a folder or label, add a pin, mark the message as read, or send a copy to another email address. This means that if you have mail forwarding set up and you mark a message as not spam, the message should be forwarded accordingly. If the message does not match any rules, it will be moved to your Inbox.
Your account's personal spam database is automatically trained with any spam messages you've deleted permanently from your Spam folder, and any non-spam messages you've moved out of your Spam folder. Once your personal database has seen more than 200 spam and 200 non-spam emails, it is automatically used to filter your incoming mail. You can expect your account's spam protection will improve over time as your personal database is trained. You can check how many spam and non-spam emails your account has learned by going to Settings → Filters & Rules and clicking Spam protection, then scrolling down to the Personal spam filter section.
Your Fastmail account's spam protection level is set to Standard, which sends messages with a spam score of 5 or higher to your Spam folder.
You can customize your account's spam filtering by going to your Settings → Filters & Rules → Spam protection screen. From here, you can choose your account's spam protection levels and customize other spam options. For more information, please see our Improving spam protection help page.
Fastmail supports whitelisting instead of the Trusted Senders section you are accustomed to. Your existing Trusted senders have been incorporated into Fastmail's spam protection to ensure that messages from addresses you've interacted with previously continue to be delivered.
Now that your account has been migrated to Fastmail, you can whitelist individual senders or domains by adding them to your contacts.
You can add an individual address as a contact by going to your Contacts screen and clicking New contact. You can also add an individual address as a contact while viewing a message by clicking Show details, clicking the sender's email address, and selecting Add to contacts from the menu. This can also be done using the People tab of the sidebar.
If you would like to whitelist an entire domain, you can do so by adding the domain to your contacts using a catch-all address, which would look like adding *@domain.com as a contact.
If a legitimate message is caught in your Spam folder, but you do not want to whitelist the sender, use the Not spam button to automatically move the message out of your Spam folder and improve how your account filters spam for you in the future.
In the Fastmail interface, filters are referred to as rules. Rules can be used to automatically perform actions on incoming messages, such as moving certain messages into a folder.
Your Pobox filters have not be automatically migrated to Fastmail as rules. You will need to manually recreate your Pobox filters as rules in the Fastmail interface.
You can create and manage your rules from your Settings → Filters & Rules screen. You can also create rules from a specific message or mailbox search.
From this screen, you can also manage your list of blocked senders. Mail sent from blocked senders and domains will be automatically moved to your Trash folder.
For more information on rules, including a list of available conditions and actions, please see our Flters & Rules help page.
For more advanced users, we also support rule creation using regular expressions and Sieve.
As part of the migration, you now have access to special Fastmail features designed to help you stay secure and productive. These features are available on all plans unless specified otherwise.
Masked Email is a feature that allows you to randomly generate unique email addresses. Instead of sharing your real email address with a new service or contact, you can use a Masked Email address to keep it private and protect yourself from data breaches and spam.
We have an official Fastmail mobile app that can be used on iOS 15+ and Android 8+ devices. The Fastmail mobile app allows you to read your email on the go without having to use an app password or enter server settings. The app also offers features to enhance your privacy and productivity, such as screen lock and custom swipes.
If you accidentally delete an email or draft, our Restore tool gives you 7 days to retrieve it. This tool can also restore contacts, events, and notes, or undo any recent changes to your contacts or events.
We offer a powerful search feature to help you find what you need. Use our advanced search tool to help you search for emails by keyword, sender, folder, and more. If you find yourself frequently searching for the same things, you can also save searches to easily find results with one click.
We offer a number of features to help you control exactly when you want to read and send mail.
Snooze lets you take a message out of your Inbox and have it reappear at a date and time of your choosing. If you receive an important email but don't want to deal with it right now, snooze is a great way to make sure you don't forget about it later. Note: This feature will only be available to customers moving to a Fastmail Standard or Fastmail Professional plan.
Scheduled send lets you choose a date and time for your message to be sent. If you need to send an important email but want it to be delivered at a time that is helpful to the recipient, scheduled send lets you do this without the risk of forgetting the messages in your Drafts folder. Note: This feature will only be available to customers moving to a Fastmail Standard or Fastmail Professional plan.
Undo send gives you 15 seconds to recall an email after you have sent it. If you see a mistake or accidentally click \"Send,\" you can undo the send and resume writing the email.
Mute conversations lets you mute replies in an email thread. If you're no longer interested in reading new messages in a conversation, muting the message will send further replies straight to your Archive folder, without any notifications.
Customers who had a Fastmail account prior to the migration now have two separate Fastmail accounts. If you’d like to consolidate accounts now that we’ve migrated your Pobox account to Fastmail, you can do so by following the steps outlined on Importing users into an account.
If you prefer to keep these accounts separate, no action is required from you. You can easily log in and switch between multiple users. Please see Switching users for more details.

Auto-purge can be enabled for a folder or a label. For folders, enabling auto-purge will permanently delete messages after a set amount of time. For labels, enabling auto-purge will either permanently delete the message or remove the label from the message, depending on your setup.
Auto-purge occurs based on when a message was placed in the folder/label, rather than when the message was received.
As an example, if you've set your Trash folder to auto-purge after 30 days, then you move a message that was received one year ago into the Trash folder, the message would not be purged immediately — it would be purged 30 days later.
Auto-purge for folders will automatically and permanently delete unpinned messages in that folder after a set amount of time.
If you have any pinned messages in the folder, those messages will not be deleted.
You can choose how many days until the messages are auto-purged. This ranges from after 1 day to 365 days.
Auto-purge for labels will automatically remove that label from unpinned messages after a set amount of time. If the messages do not have any other labels applied, then those messages will instead be permanently deleted.
Pinned messages will not have the label removed or be deleted.
You can choose how many days until action is taken on the messages in the label. This ranges from after 1 day to 365 days.
DMARC (Domain-based Message Authentication, Reporting and Conformance) is a sender authentication protocol that builds on DKIM and SPF. It lets the owner of a domain decide what should happen to an email should it fail both DKIM and SPF checks.
\n\nDMARC is a strong anti-phishing feature that lets the receiver verify that the From header (the user-visible sender) aligns with the DKIM signed delivery header, or that the From header matches the SPF signed delivery domain and that it's sent from an address validated by SPF. In short, DMARC lets the receiver verify that the delivery address (on the envelope) matches the user-visible address (the letter inside) and that the person who sent it is allowed to do so.
\nDMARC also provides more robustness for mail being forwarded: SPF will fail but DKIM should survive.
\nIf neither the DKIM nor the SPF checks pass, DMARC lets the domain owner specify if the mail should be quarantined or rejected (and sent to a reject address).
\nFastmail users do not need to set a DMARC policy for their domain to work, but users who would like to set a DMARC policy on their domain are welcome to do so. By default, domains that have their DNS handled by Fastmail have a DMARC policy of p=none.
Fastmail domains have a DMARC policy of p=none, which means recipient mail servers should report whether the message passes or not, but not change deliverability. This allows users to send mail using our domains from anywhere, for legacy reasons.
Many email clients don't preserve message integrity when mail is forwarded, which can break DKIM as well as SPF.
\nMailing lists still alter message fields, which breaks DKIM, and they forward mail, which breaks SPF. Mailing list software is being brought up to date to deal with this by adjusting the \"From\" header and re-signing the message with updated DKIM information.
\nDespite the advancements in sender authentication protocols, many users are still not evaluating their email with an educated, critical eye. All the automated checking in the world still can't stop a user from clicking on a message sent from \"PayPa1\" <no_really_this_is_paypal@hotmail.com>.
If Fastmail handles the DNS for your domain, then your domain will automatically have a DMARC policy of p=none. To change this to either a p=quarantine or p=reject policy, you'll need to disable this automatically generated DMARC record and create a new one with your desired enforcement policy.
If we don't handle the DNS for your domain, you can add a DMARC record for your domain in the control panel of your domain host with a compliance policy of p=none, p=reject, or p=quarantine. You can publish a DMARC policy by adding a TXT record for _dmarc.yourdomain.com. For more information and record generator tools that can help you set up DMARC, we recommend going to DMARC.org.
If you have any questions about setting up a DMARC policy, feel free to reach out to our support team for assistance.

Fastmail can be added to your device as a progressive web app, or PWA. Having Fastmail installed as a PWA allows you to access Fastmail as if it is an individual app on your device. Once installed, you'll see a Fastmail icon/shortcut, which can be added to your taskbar or dock if desired, and clicking on the icon/shortcut will open Fastmail in its own window.
To install Fastmail as a PWA, you can first log in to your Fastmail account on your preferred web browser. Depending on if your browser supports this, you'll see an icon for installing PWAs in or around the address bar area of the browser. Clicking on the icon should allow you to install Fastmail as an app.
Note: Depending on your device and browser, you may not be able to install Fastmail as a PWA. Below, we've included steps for installing Fastmail as a PWA on common browsers that support this.
In April 2024, we introduced changes to our subscription plan offerings and pricing. On this page, we'll cover the most notable changes to our pricing and plans.
These updated plans became immediately available to everyone who signed up for Fastmail on or after April 8, 2024.
Customers on these plans are billed through Paddle. If you're looking for information on Paddle billing, please see our help page.
Fastmail customers on our old plans are being migrated to new plans and pricing on an ongoing basis. We’ll email you before your first renewal under the new plans to ensure you have all the details, including the price of your renewal, which may change. To ensure that this message — or any other message — is a legitimate communication from Fastmail, look out for the white check mark in a green circle. For more information on identifying legitimate mail from the Fastmail team, please see our Phishing help page.
We've introduced new multi-user plans to make it affordable for your whole family to get started on Fastmail:
With these plans, each user will have their own separate login information, mailboxes, and storage. Each user receives 50 GB of storage.
In addition to having your own private mail, contacts, and calendars, users on Duo and Family plans can easily share information with other users in their account:
Users on these plans can set up custom domains that can be used to create email addresses for any users in their account. Admins on these plans also have access to options that help them manage their users' accounts.
Our Standard plan has been renamed as the Individual plan, and is now $6 a month.
Our Basic plan is now $4 a month per user. Mail storage on this plan has been increased to 5 GB.
We've introduced three new business plans, designed for companies who'd like to use Fastmail for their business needs.
In addition to having your own private mail, contacts, and calendars, users on any Business plan can easily collaborate by sharing information with other users in their account:
Users on the Business Standard and Business Professional plans can set up custom domains that can be used to create email addresses for any users in their account. Users on the Business Basic plan can also have email addresses at custom domains, provided there is at least one admin in the account on a Business Standard or Business Professional plan.
If you are located outside of the US, we have listened to your feedback: Customers on our updated plans can now be billed in select local currencies, instead of USD only.
We can now accept payments in the following currencies: AUD, BRL, CAD, CHF, CSK, DKK, EUR, GBP, HKD, HUF, INR, JPY, KRW, MXN, NOK, NZD, PLN, SGD, USD, and ZAR.

Any message that you've started composing will be automatically saved into this folder, so you can return and finish sending it whenever you'd like.
When composing a message, you can save the message to your Drafts by clicking Save draft, using the keyboard shortcut Ctrl+S, or exiting out of the composer.
You can cancel a scheduled message by going to your Scheduled folder, opening the message, and clicking the Cancel send button.
The message will move to your Drafts folder and re-open in the Compose screen. From here, you can make any desired edits or choose a new time for the message to be scheduled.
If your account is unable to send for any reason (e.g. the account subscription is long overdue), any messages scheduled to be sent during that time will be moved to your Drafts folder.
If you need to send the same type of message on a frequent basis, you can save time by creating a template. Whether you send, save, or discard the draft, the original template will stay in the Templates folder or label. See our Templates help page for more details.
Draft messages can be shared with other users in your account by dragging-and-dropping the draft into a shared folder.
When more than one version of the same draft is open across multiple tabs, we save the most recently edited one. This means that if the most recently edited version isn't the preferred draft and the window with the preferred draft is closed, then that version of the draft will be lost.

Using our View and Sort options, you can read your mail in the order that makes sense to you.
By default, these options are set to view All mail and sort by newest first.
If you have the side reading pane enabled, you can find these options by clicking the icons at the top of your message list:
If you have the bottom reading pane enabled, or if you have the reading pane hidden altogether, you can find these options displayed along the top right-hand side of your message list:
The View options allow you to display emails based on what type of emails you want to see:
The view reverts back to All mail if you navigate away from the folder or close your tab.
The Sort options allow you to sort the order that emails appear in your message list from top to bottom. Options include sorting by time, sender, subject, and size:
The sorting option you choose will be remembered for each individual folder/label.
You can choose how pinned emails are sorted in your mailbox:
Fastmail does not support DNSSEC. If your domain has DNSSEC enabled, it can cause issues with DNS and potentially prevent you from successfully sending or receiving mail.
\nBelow are some common issues that could occur due to DNSSEC:
\nIf you encounter any of these issues with your domain, but your DNS records look fine otherwise, please check to see if the domain has DNSSEC enabled. If DNSSEC is enabled, disabling it should resolve the issue.
\nFor more on why Fastmail doesn't support DNSSEC, you can view our blog post detailing this.

\nNote: Mute is not available to users on Basic plans. Conversation grouping must be enabled for the mute option to appear.
\nYou can mute a conversation by selecting or opening it, then clicking the More button from the toolbar and selecting Mute replies.
\nYou can unmute the conversation at any time by opening it and clicking the Unmute button. You can also unmute the conversation by selecting it, clicking the More button from the toolbar and selecting Unmute.

\nYou can also right-click the message in the list and select Mute replies (or Unmute replies) from the menu that appears.
\nIf you'd like to see all of your muted conversations, you can search for muted conversations using is:muted. If you frequently use is:muted, you can also save the search for easier and faster access.
When creating rules, you can add You have muted the conversation or You have not muted the conversation as conditions.
\nIf a muted conversation matches one of your rules, the rule's actions will still be applied, except for \"Notify me.\" The \"Notify me\" action will be ignored, and you will not receive a notification.

There are also third-party applications that we can recommend which provide additional accessibility features.
Within the Fastmail interface, we provide options to customize your account's styling to fit your needs. We also include keyboard shortcuts, which can help you navigate your account more quickly.
You have the option to change the theme of the Fastmail interface. We offer a light mode and a dark mode, and a few different preset color options. You can also set your own custom theme colors if preferred.
We also offer two button styles, the Modern and Bold styles. To make buttons more prominent on the interface, we recommend using the Bold button style.
These changes can be made via the Settings → Display options screen, in the Theme section.
You can set your account to use rich text or plain text. Rich text allows for visual styling of emails. This means that when you receive emails, you'll see any visual styling that senders have added to their emails (such as bolding or italics). If you set your account to view emails in plain text, then the visual styling of emails will be stripped away and you'll see the emails in a simple format.
If you have difficulty reading stylized emails, then we recommend you choose the plain text option. This can be set via the Settings → Display options screen. In the Reading section, choose the Plain text option under View messages in.
Changes to text size and font can be made via the Settings → Display options screen, in the Accessibility section. Increasing the font size and choosing a font style that fits your preference can make text easier to read. (Please note that this option is only available when accessing Fastmail through a web browser or the desktop app. On the mobile app, the font size will follow the system font size on your device.)
The font size of your account can be increased or decreased by clicking the Text size dropdown. We offer text sizes from \"Small\" to \"XXXL.\"
The UI Font is the font style of our interface. By default, the interface uses the Proxima Nova font. If you prefer, you can select the System font option, which will then use the font style that your device is using. If you're using plain text on your account, you can also choose to use a monospace font style by enabling the Use a monospaced font for plain text option.
We offer preset keyboard shortcuts that you can utilize for easier navigation and use of your account. Enabling keyboard shortcuts will allow you to perform certain actions directly with your keyboard, instead of having to use your mouse or touchpad.
Keyboard shortcuts can be enabled via the Settings → Display options screen, in the Accessibility section. Click on the toggle for Enable keyboard shortcuts to enable/disable it.
For more information, please see our Keyboard shortcuts help page.
The VoiceOver feature on macOS and iOS provides spoken and Brailled descriptions of items on the device's screen. For macOS, it provides control of the computer through the use of the keyboard. For iOS, controls use taps and other gestures. This can work well with the Fastmail interface, and also the Apple Mail client.
If you want to use the Apple Mail client along with VoiceOver, you can set up your Fastmail account on Apple Mail. Please note that you'll need to use an app password when setting up your Fastmail account on third-party mail clients.
For more information on VoiceOver, you can view the Apple help pages for VoiceOver on macOS and VoiceOver on iOS.
If you have any concerns regarding the accessibility of Fastmail, please feel free to reach out to us and let us know! We're always looking to improve the user experience and interface of Fastmail, so hearing from our users is very helpful.
If you have suggestions of accessibility features offered by other third-party apps that you'd like to share with us, we'd love to hear this as well.
You can reach out by submitting a ticket via our online form or by emailing support@fastmail.com.
