Connectors / Proton Mail
Connect Proton Mail
Proton Mail offers IMAP and SMTP only through Proton Mail Bridge, a desktop app that runs a mail server on your own computer and needs a paid plan. A web app like Mailpitcher cannot reach it, so Proton can't be connected for now. Planned
Bridge creates a local email server on your computer; there are no public IMAP or SMTP servers to enter here.
Checked against the provider's documentation on 10 October 2026.
Connect in Mailpitcher
Add the mailbox
Choose Proton, then enter your address and password. The settings above are filled in for you.
Test the connection
Mailpitcher checks that it can read and send before it saves the mailbox. Each mailbox sends 100 emails a day by default, and 50 a day for its first 3 days.
