Proton Mail Bridge is an application that seamlessly encrypts and decrypts your mail as it enters and leaves your computer. It allows you to fully integrate your Proton Mail account with most clients that support IMAP and SMTP protocols, with official support for Microsoft Outlook, Mozilla Thunderbird, and Apple Mail.
Proton Mail Bridge also allows you to import emails into your Proton Mail account from other email accounts connected to the same client, as well as run full-text searches of your Proton Mail emails.
Proton Mail Bridge is currently available for macOS, Windows, and Linux users.
You can download the app, find answers to frequently asked questions, and get full support on the Proton Mail Bridge homepage(new window).
Proton Mail Bridge is currently available only if you have a paid Proton Mail plan.
We do not offer POP3 support, but Proton Mail Bridge allows you to download all of your mail into your client and export it from there.
If you’re subscribed to one of our business plans, you can also set up SMTP on your business applications or devices to send emails with Proton Mail.
