About

Who reads your mails? With regular mails you, the receiver, all mail providers and maybe others can read them. With end-to-end encrypted mails only the sender and the receivers can read them. Our iOS-App Letterbox makes end-to-end encryption easy to use, is compatible with most mail providers and supports the standard encryption protocol OpenPGP. Letterbox is similar to common mail apps but indicates the security state of incoming and outgoing mails. We disinguish between a confidential and insecure mails. Letterbox is a free open-source mail client on iOS and part of an ongoing research project at the Freie Universität Berlin, Germany. Letterbox is still under development but you can soon use the app on your device with Apple's TestFlight app.

Pros & Cons from Real Users

Pros

  • Super easy to use and very well designed. Feels like a faster and more intuitive version of Notion. Has subpages, slash commands, really good comment threading.
  • Easy to use; all the basics are there. Easy import of all Google Docs documents. Nice and crisp and responsive.

Cons

  • Doesn't have selectable icons for docs and folders. Can be a bit challenging to organize if you aren't diligent with folders and subpages.
  • Export to PDF sometimes has a few glitches. Some missing features, but all the basics are there.
