    Yes, of course you can. I am aware of this app but I have not yet fully tested it. I know about K-9 Mail too. Also not tested. Source: almost 2 years ago

    I agree because I need to test it. I am aware of K-9 Mail and FairMail though. Source: almost 2 years ago
  • Email send error javax.crypto.BadPaddingException: pad block corrupted
    I've rebooted quite a few times. Updated the app too. I don't use a VPN. I installed k9-mail to test and that works without problems. https://github.com/k9mail/k-9. Source: about 2 years ago
  • Gmail App Alternative focused on privacy?
    On Android the usual recommendations are FairEmail or K-9 Mail. Both are fully open source and privacy focused, it basically comes down to your personal preference. For them to work with your Google Account you will probably have to create an app password. Source: almost 3 years ago

  • What email client(s) do you prefer for Windows?
    Polymail - This one is a lot like Twobird but with a lot more features. It's a different type of email client. It's really cool, but the Windows version is just a web app. It's available on iOS as well. Source: over 2 years ago
