Create a DMARC TXT record with the policy, report addresses and alignment you choose, then check it after publishing.

How it works

What it does

Pick a policy (none to monitor, quarantine or reject to enforce), optionally add aggregate report addresses, and copy the record to publish at _dmarc.your-domain.

Limits

What it cannot tell you

  • It generates text only and does not confirm the record is published.
  • Report addresses on another domain only receive reports if that domain authorizes yours; the DMARC checker looks at this.
  • Enforcing a policy before SPF and DKIM align for all your mail can block legitimate messages; start with p=none and read the reports.
  • Runs in your browser; nothing you enter is sent anywhere.
