DMARC Checker
Look up and validate your DMARC record. See your policy, enforcement percentage and reporting addresses - and whether you meet Google & Yahoo sender requirements. Free, no signup.
Policy
Reads your p= value - none, quarantine or reject, and warns if you're only monitoring.
Enforcement %
Checks pct so you know if your policy applies to all mail or just a sample.
Reporting
Confirms rua/ruf addresses so you actually receive aggregate reports.
Compliance
Tells you whether your setup satisfies Google & Yahoo bulk-sender rules.
DMARC FAQ
What does DMARC do?
DMARC ties SPF and DKIM together with alignment, tells receivers what to do when a message fails (none/quarantine/reject), and sends you reports on who is mailing as your domain.
Is p=none enough?
No. p=none only monitors - it doesn't stop spoofing. It's a fine starting point, but move to quarantine then reject once your reports look clean.
