In iOS 14, you can now change the default mail app to the Fastmail mobile app.
This means that you'll be taken directly to the Fastmail mobile app when you tap on an email address link in another app that supports mailto: links.
Change your default mail app
- Open the Settings app.
- Tap Fastmail.
- Tap Default Mail App, then Fastmail. You should see a checkmark next to the Fastmail app once you've made the change.
- Tap < Fastmail at the top-left of the screen to save your changes.
Below are current known issues when updating the default mail app:
If you have previously set up the Apple Mail app with a Fastmail profile, then tapping mailto: links in Safari will still open with Apple Mail rather than the Fastmail app.
There's a known issue that when you change your Default Mail App on iOS 14, it reverts back to Apple Mail when you reboot your device. This occurs on all mail clients, and not just the Fastmail mobile app. Apple has fixed this in iOS 14.0.1, which is currently available.
If you are a multi-account user, tapping a mailto: link will take you to the last Fastmail account you had open on the app. You won't be prompted for the account you wish to use.
There's a known issue with sending identities in the Default Mail App on iOS 14. If you choose an identity while sending an email in the app, another random identity from the account may be used to send it.
