Proton Mail Bridge(new window) is an application that integrates your Proton Mail account with IMAP and SMTP email apps. Bridge gives you the security and privacy benefits of Proton Mail within the user interface of your favorite email client.
Bridge is supported for three major email clients.
- Apple Mail
- Outlook 2011/2016/2019
- Outlook 2010/2013/2016/2019
Each email client implements the IMAP standard slightly differently, so those using Bridge with an untested client may experience crashes or other bugs.
