K-9 Mail

Full-featured email client

E-mail client supporting multiple accounts, POP3, IMAP and Push IMAP. Can do encryption if APG and/or OpenKeychain is installed -- depending on the version. Settings and account configurations can be exported so that they can be imported easily if you are switching packages/signatures: a file manager will need to be already installed to achieve this.

If you would like to contribute financially to k9mail, consider donating to the local SPCA (Societies for the prevention of cruelty to animals).

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.
