What is Letterbox?
Who can access your emails? With traditional emails, you, the recipient, and all email service providers may have visibility into the contents, along with potential others. In contrast, end-to-end encryption restricts access solely to the sender and the intended recipients, ensuring greater privacy. The iOS app known as Letterbox enhances the end-to-end encryption experience, supporting a wide range of email services and employing the widely recognized OpenPGP encryption protocol.
Although Letterbox operates like many other email applications, it specifically emphasizes the security status of both incoming and outgoing communications, empowering users to identify which emails are secure and which are not. Being a free and open-source email client for iOS, Letterbox aligns with an ongoing research project at Freie Universität Berlin. While it is still in development, users will soon have the chance to try the app on their devices via Apple's TestFlight platform, making secure communication increasingly available to the public. This development not only aims to improve user understanding of email security but also strives to maintain a seamless and intuitive user interface. As technology evolves, the importance of secure communication will only continue to grow.
