mailbridge

Let Claude and ChatGPT work with your email, on your terms

mailbridge connects your own mailboxes (Gmail, iCloud, Fastmail, Yahoo, Zoho or your own domain's mail server) to AI apps such as Claude, ChatGPT and Claude Code. You choose which mailboxes each app may use, and whether it may send, and to whom.

Early access

mailbridge is invite-only while a small group tries it out. If you have an invite, sign in with the address it was sent to. If not, ask whoever told you about mailbridge to invite you.

Sign in

How it works

  1. Add a mailbox. Sign in with a link we email you, then add a mailbox with its address and password (an app password for Gmail, iCloud, Yahoo, Fastmail and Zoho). mailbridge finds the server settings for most providers.
  2. Connect an app. Add mailbridge to Claude, ChatGPT or Claude Code with the address below. The app sends you to mailbridge to approve it.
  3. Set the rules. Pick the mailboxes it may read and organize. Sending stays off unless you turn it on, and then only goes to the recipients you list.
