Free DMARC Record & Report Analyzer
Paste a DMARC record (v=DMARC1; …) or a DMARC aggregate (RUA) report in XML. For a record we grade the policy (none/quarantine/reject), pct, subdomain policy and reporting; for an aggregate report we summarise total messages, the DMARC pass rate and the top sources of failing mail. Runs in your browser.
What this dmarc analyzer checks
How it works
In-browser· parsed entirely client-side- 1You paste either a DMARC record (v=DMARC1; …) or a DMARC aggregate (RUA) XML report; we auto-detect which.
- 2For a record we grade policy (none/quarantine/reject), pct, subdomain policy, alignment and reporting; for a report we summarise total messages, the pass rate and the top failing sources.

Why it matters
DMARC is what actually stops attackers from spoofing your domain — but most domains sit on p=none and never read the reports, so they get the monitoring without the protection. Reading the aggregate reports tells you when it is safe to move to reject.
Frequently asked questions
What does this accept?
Either a DMARC TXT record (the v=DMARC1; … string) or a DMARC aggregate report (the XML emailed to your rua address). It auto-detects which one you pasted.
Why is p=none flagged?
p=none only monitors — it does not block spoofed mail. The goal is to use the aggregate reports to authorize all your legitimate senders, then move to p=quarantine and finally p=reject.
Is anything uploaded?
No — the record/report is parsed entirely in your browser.
