How to Add ProtonMail to Apple Mail on Mac Using Bridge

Connect your encrypted ProtonMail account to Apple Mail on Mac using ProtonMail Bridge. Requires a paid Proton plan.

ProtonMail requires its Bridge application to work with Apple Mail. Bridge runs locally and acts as a secure gateway between ProtonMail's encrypted servers and your email client.

Paid plan only: ProtonMail Bridge is available for paid subscribers (Mail Plus, Proton Unlimited, or Business plans).

Step 1: Install and Configure ProtonMail Bridge

  1. Download Bridge from proton.me/mail/bridge (Mac version).
  2. Open Bridge and sign in with your ProtonMail account.
  3. In the Bridge app, select your account and note the IMAP address, ports, and Bridge password.
  4. Keep Bridge running — it must stay open for Apple Mail to work.

Step 2: Add the Account in Apple Mail

  1. Open Apple Mail → Mail → Add Account → Other Mail Account → Continue.
  2. Enter your ProtonMail address and the Bridge password (not your ProtonMail login password).
  3. Enter the local server details from the table below.
  4. Click Sign In.
