The simple route

How it works

  1. 01

    A visitor writes to you

    They send a message to [email protected], the address you share everywhere.

  2. 02

    Cloudflare routes it

    Email Routing quietly forwards it to your Gmail inbox — free and near-instantly.

  3. 03

    You reply as your domain

    Resend SMTP delivers your Gmail reply from your own address, with trust records in place.

A real request, not a mockup

Send a message. It is submitted to this site's server endpoint, then delivered to the mailbox behind this demo.

Under the hood

Mail providers need proof.

SPF says which services may send mail for your domain. DKIM adds a signature that proves the message was not altered. DMARC tells receiving providers what to do when either check fails.
