How do I create a DMARC record?

Choose a policy, the percentage of mail it applies to, where aggregate (rua) and forensic (ruf) reports should go, and how strictly SPF and DKIM must align. The generator builds a correctly formatted v=DMARC1 TXT record to publish at _dmarc.yourdomain.

How to generate and publish a DMARC record

Choose a policy - start with none if you have not used DMARC before.
Enter the email address that should receive aggregate reports.
Click Generate DMARC Record and copy the result.
Add it as a TXT record named _dmarc at your DNS provider, then verify it with the DMARC Checker.
