Set up a custom domain

Use your own domain (you@yourcompany.com) with Airfree Mail by publishing a few DNS records.

A custom domain lets you send and receive at your own address. You add the domain in settings, then publish the DNS records we generate at your registrar.

What you publish

MX records pointing mail for your domain to Airfree Mail.
An SPF record authorising our servers to send for you.
A DKIM record so your mail is cryptographically signed.
A DMARC record setting your authentication policy.

Verifying

After publishing, the domain settings page re-checks each record and marks it verified. DNS can take a few hours to propagate, so wait before troubleshooting a record that looks correct.

For the exact SPF/DKIM/DMARC values and how to verify them, see the blog guide on email authentication.
