FairEmail

Fully featured, open source, privacy oriented email app for Android

FairEmail is easy to set up and works with virtually all email providers, including Gmail, Outlook and Yahoo!

FairEmail might be for you if you value your privacy.

FairEmail is an email client only, so you need to bring your own email address.

FairEmail does not support non-standard protocols, like Microsoft Exchange Web Services and Microsoft ActiveSync.

Downloads

Supported download locations:

• GitHub
• Play store
• Play store (test)
• F-Droid — Please read this FAQ
• IzzyOnDroid (verified GitHub release)
• AppGallery (the AppGallery app can be downloaded here)
• Amazon (the APK file repackaged by Amazon is incomplete! An issue report was never answered by Amazon.)

Please see this FAQ about the differences between the different releases.

Important: Only the versions in the Play Store and GitHub are official releases. Support for other releases from alternative app stores, etc. is limited.

Important: after enrolling in the Advanced Protection Program you cannot use third party email apps anymore, please see this FAQ for more information.

To download a GitHub release you might need to expand the assets section to download the APK file.

The GitHub version is being updated more often than the Play store version. The GitHub release will automatically check for updates on GitHub (this can be turned off in the miscellaneous settings).

F-Droid builds new versions irregularly and you'll need the F-Droid client to get update notifications. To get updates in a timely fashion you are advised to use the GitHub release.

Important: There is support on the F-Droid build only if the version number of the F-Droid build is the same as the version number of the latest GitHub release. Please see here for more information on third-party builds.

Because F-Droid builds and GitHub releases are signed differently, an F-Droid build needs to be uninstalled first to be able to update to a GitHub release.

The best way to verify the integrity of an APK file is documented here.

Compatibility

FairEmail requires at least Android 6 Marshmallow.

FairEmail is supported on smartphones and tablets only, and for example not on TVs and E Ink devices.

Individual message notifications are available on Android 7 Nougat and later only because earlier Android versions do not support notification grouping.

Notification settings (sounds) per account/folder/sender are available on Android 8 Oreo and later only because earlier Android versions do not support notification channels.

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

Please see here for known problems.
