Open source, privacy friendly email app for Android

FairEmail

Open source, privacy friendly email app for Android

This email app might be for you if your current email app:

• takes long to receive or to show messages
• can manage only one email address
• cannot handle a large number of messages
• cannot show conversations
• cannot work offline
• looks outdated
• is not maintained
• stores your email on their servers
• is closed source, potentially violating your privacy

This app is minimalistic by design, so you can concentrate on reading and writing messages.

This app starts a foreground service with a low priority status bar notification to make sure you'll never miss new email.

Compatibility

FairEmail requires at least Android 5 Lollipop. Individual message notifications are available on Android 7 Nougat and later only because earlier Android versions do not support notification grouping.

FairEmail will work properly on devices without any Google service installed.
