Letterbox Description
Who reads your mail? Regular mails can be read by you, the recipient, and possibly other recipients. End-to-end encryption mails are only readable by the sender and receiver. Our iOS-App Letterbox is compatible with the majority of mail providers, and supports OpenPGP encryption.
Letterbox is similar in appearance to other mail apps, but it also indicates the security status of incoming and e-mails. We distinguish between confidential and unsecure mails.
Letterbox is a free, open-source mail client for iOS that is part of a research project at Freie Universitat Berlin in Germany. Letterbox is currently under development, but you will soon be able to use it on your device using Apple's TestFlight application.
