  • Is there a way to have Shortcuts search my email subjects for a specific word, and if it finds that word, copy the body of the email into a new Note?
    The airmail app https://airmailapp.com has a shortcut action that allows you to search emails and returns things, not used it myself but you could try that. Source: about 1 year ago
  • Best calendar/mail app?
    I once trusted AirMail, but they created so many extra folders and kept switching around the client interface. It haunts me to this day, since I recommended it to so many people who hated it. Source: about 1 year ago
  • Mail app suggestions iOS/MacOS
    You might want to consider Airmail Pro or Business as an alternative. I think it has all the features you are looking for. They offer a privacymode and some privacy features but I don't have any experiences with this app or company. Good luck! Source: about 2 years ago
  • Is there a mail client or iOS that can reliable search *all* mail?
    I am using Airmail and I always find what I search for. On Mac, iPad and iPhone. Https://airmailapp.com. Source: about 2 years ago
  • What does mute do?
    Also, I don't think Airmail responds on here much, but I've found if you click the chat icon at the bottom right of this page, they're pretty good about responding by email. You can also check with their Slack page if you use their beta app, which BTW, is free. https://airmailapp.com/. Source: over 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
