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?

• 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.

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).
