The FastMail mobile app

The official FastMail mobile app is the best way to use FastMail on your iPhone, iPad, iPod or Android device.

The app works on iOS 10.x+ and Android 5.x+ devices. Your device must be online to access your information. Users who don't meet these requirements can still use the web interface, fully compatible with mobile browsers, at https://www.fastmail.com.

Did you know?

• To select all messages, select one, then the header will provide an option to select all.
• Customise your notifications via the in-app Notification Settings.

• iOS: To rapidly return to the top of the screen, tap the top status bar.
• iOS: To force a check for new mail, pull down on the message list view.
• iOS: You can share your mail content with other apps: tap a message, use the action arrow to bring up the menu and use Share Message Content... to select what to send, and where.
• Android: You can send text content from other apps to create a new mail item.

Troubleshooting

Except where noted, these are present on all platforms.

Android: login issues

• Please see our dedicated troubleshooting page on Android login issues.

iOS: trying to open a pdf on iPad, or open a password-protected pdf crashes the app.

• No workaround currently available. We're working on a fix.

Android: notifications are unreliable

• We have made a number of improvements and continue to apply new fixes.
• In the meanwhile, you can try the workaround for your device outlined at Don't Kill My App.

Alerts on shared calendar events don't show event preview text

• This is a server issue and we are working on a fix.
• It won't require an app update to address.

Calendar alerts don't work if offline

• If your device is offline when the alert is due to arrive at your device, you will receive no alert.
• If you require alerts when your device is offline, we recommend syncing your calendar with your device over CalDAV.

No dark mode theme

• We want to bring this to you all, and it's on our list of goodies to build!

No offline support yet

• We are building the infrastructure to support offline capability.
• We don't know when the feature will be ready.

Android: notifications don't work without Google Play Services

• GCM (or FCM as it once was known) or a compatible Google Play service is required for notifications to work on Android.
• Notifications are encrypted as they pass through the Google servers.
• (Pushy support has been removed as it was too unreliable).

Android: older devices

• Do not support folder selection or contact filtering.
• Preference saving on older devices is currently broken. You can't choose your sound, vibration, LED color or set quiet hours.
