K9 Material (unofficial)

Send and receive mails

Note: Since 10/2017, this app is no longer maintained.

This is a unofficial fork of the K-9 Mail email client with a material design style instead of the normal one. It will be updated in tandem with the main repository.

Packages

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
