This checker helps read a DMARC record in plain terms. It parses the tag-value pairs, shows the active policy and flags settings that often explain why mail is only monitored or only partly covered.

What to review

Look at p, sp, np, rua, ruf, adkim, aspf and fo. The checker also calls out legacy pct, rf and ri tags because current DMARC guidance moved away from those controls.

Limits

The tool does not query DNS, verify report mailbox ownership or judge deliverability. It reviews the DMARC value you paste.
