ProtonMail Bridge for Linux is a desktop application that integrates ProntonMail's privacy and security features with an email client. This application is compatible with most email clients that support IMAP and SMTP. ProntonMail Bridge is available for Windows, Mac, and Linux.
This application's key feature is that it encrypts all the email messages that you send and decrypts the email messages that you receive to your ProtonMail account. You can save all emails in the email client from which you access your account.
