Proton Mail Bridge(new window) is an open-source application that allows you to fully integrate your Proton Mail account with any program that supports IMAP and SMTP. This includes Microsoft Outlook, Mozilla Thunderbird, and Apple Mail.

It runs in the background on your computer and seamlessly encrypts and decrypts your mail as it enters and leaves your computer.
