DMARC Record Checker

Read a domain’s DMARC policy and see missing tags, monitoring-only policies, partial enforcement and report-address problems.

How it works

What gets checked

DMARC lives at _dmarc.<domain>. We fetch that TXT record, parse the tags, validate policy, percentage, alignment and report addresses, and check that external report recipients have authorized your domain.

Limits

What it cannot tell you

  • It reads public DNS through a DNS-over-HTTPS resolver. It does not send mail and cannot say whether a message will be delivered or pass authentication.
  • It checks the exact domain you enter. A subdomain without its own record may inherit the organizational domain’s policy; this tool does not look that up.
  • Authorization checks cover up to 3 external report domains.
  • Anonymous use is limited to 30 checks per hour.
