Setup guide
Set up a custom-domain inbox with 2 DNS records
A focused setup flow for people who already own a domain. Add the domain once, publish two DNS records — a TXT record that proves ownership and an MX record that routes incoming mail — then press Check DNS. Every address at the domain then receives mail in your catch-all inbox.

Add TXT and MX records

Check DNS
Press Check DNS once the records have propagated.
Receive mail
Mail to any address at your domain appears in your catch-all inbox and through the API.

Free Domain Mail only receives email — it never sends or forwards mail on your behalf. Public temporary addresses are deleted after 10 minutes; custom-domain mail is kept for 30 days. Attachments are never stored, only their name, size and type.
