Mail gateways

Give people mailboxes on your own domain through a Cloudflare Email or Resend gateway.

A mail gateway lets people on your instance use addresses on your own domain without a mail server. You run the gateway, register it in the owner dashboard, and give each person a token for their address.

• What is a gateway mailbox: how gateways work and what to expect from them.
• Set up the Cloudflare Email gateway: a Cloudflare Worker for one domain.
• Set up the Resend gateway: a small service for one domain, on Resend and Postgres.
• Mailbox tokens: create, list and revoke the tokens people connect with.
