Email authentication for your domain
Understand SPF, DKIM and DMARC before enabling outbound sending.
A clear four-step setup
Keep your registrar and DNS provider. We show the exact records your domain needs, then make the rest of the workflow simple.
Authentication is the foundation
TXT proves control. MX directs incoming mail. SPF, DKIM and DMARC give receivers evidence that your messages are legitimate.

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.
