v=DMARC1; p=none

Add this as a TXT record with host _dmarc in your DNS settings

Add reporting emails

Without aggregate reports (rua), you won't know who is sending email as your domain. Add a reporting email to monitor your DMARC results.

Implementation path

  1. Start with p=none and add reporting
  2. Monitor reports for 2-4 weeks to identify all senders
  3. Ensure all legitimate senders pass SPF and DKIM
  4. Move to p=quarantine with pct=10
  5. Gradually increase percentage to 100%
  6. Finally move to p=reject for full protection

About this tool

DMARC builds on SPF and DKIM to give you control over what happens when emails fail authentication. This generator helps you create a properly formatted DMARC record with the right policy, reporting, and alignment settings. Start with a monitoring policy and gradually enforce. Verify your generated record with our DMARC checker and monitor propagation with the DNS propagation checker.
