Proton Mail Bridge

About

Proton Mail Bridge is an application designed to synchronize encrypted emails from Proton Mail with desktop email clients like Mozilla Thunderbird, Apple Mail, and Microsoft Outlook. Originating from Switzerland, it emphasizes privacy protection and encryption, offering features such as GPG/PGP compatibility, dark mode, and encrypted email. The software is available on Mac, Windows, and Linux platforms under a paid and open-source license. User reviews indicate mixed experiences, with some users praising its utility for integrating Proton Mail with desktop clients, while others report issues with Thunderbird IMAP folders, leading to mail duplication and movement problems. The project is actively maintained on GitHub and has a presence on Facebook and Twitter.
