Setting up your iwantmyname domain to work with your Fastmail account is quick and easy.
iwantmyname offers one-click domain setup with Fastmail. This will set up all the MX, DKIM, and SPF records you need to send and receive mail at Fastmail.
Advanced instructions for setting up MX records can be found here.
1. Add your domain to Fastmail
We have a setup guide to help you get your domain working as quickly and easily as possible.
After you have purchased your domain from iwantmyname, log in to Fastmail and go to the Settings → Domains screen.
Add your domain(s) (e.g.
mydomain.com). Using the Add Domain button brings up the new domain screen. Type your domain into the text box.
If your domain has been purchased from iwantmyname, we will display this on the next screen. You can also choose iwantmyname from our list of supported registrars.
Follow the wizard to add your email addresses to Fastmail. The wizard will ask you if you have a website at your domain. Answer Yes or No.
Please note: The domain setup wizard is not currently available to users on legacy plans. If you are on a legacy plan, you will need to add users or addresses manually in order to receive mail at your custom domain.
2. Enable Fastmail at iwantmyname
Note: We recommend making these changes at a time that you do not expect much mail to be sent to your domain
Log in to your account at iwantmyname.
In the Domain List on your account, find the domain you want to use with Fastmail, and click Install new service. Choose Fastmail.
Click Install Fastmail.
iwantmyname will set up all the necessary records to get your email working.
To check all your settings are correct, click Check Now at the domain wizard (or Recheck DNS if you have already completed the wizard). Your domain should now say
Active. MX records set.
