Free DMARC Record Checker
Enter a domain to look up its DMARC record. We'll show whether DMARC is configured, the policy in use, and whether spoofed emails will be enforced.
What this DMARC checker checks
This free DMARC checker looks up the DMARC record on the domain you enter and reports whether one exists, which policy it uses (none, quarantine, or reject), and therefore whether spoofed emails claiming to be from your domain will actually be stopped. DMARC is a DNS TXT record at _dmarc.yourdomain.com that tells receiving mail servers what to do with mail that fails authentication.
DMARC works alongside SPF; check your sender policy with the SPF checker.
Why DMARC matters
Without DMARC, anyone can send email that appears to come from your domain, which fuels phishing and damages your brand and deliverability. DMARC lets you tell the world's mail servers to quarantine or reject those forgeries, and to report back on who is sending as you.
A policy of p=none only monitors; it does not protect. Many domains publish p=none and assume they are covered when spoofed mail still lands in inboxes. Moving to p=quarantine and then p=reject is what actually stops spoofing.
How to fix your DMARC record
DMARC is configured at your DNS host (the same place you manage your domain's other records):
- Add a TXT record at _dmarc.yourdomain.com starting with v=DMARC1.
- Start with p=none plus a rua= reporting address to gather data on who sends as you, without affecting delivery.
- Once your legitimate senders pass, tighten to p=quarantine, then p=reject to actively block spoofed mail.
- Make sure SPF and DKIM are aligned first, or a stricter DMARC policy could block your own legitimate email.
Honest limits
This tool reads the published DMARC record for the domain you enter and reports the policy. It does not process aggregate DMARC reports or verify DKIM alignment end to end. Email authentication (DMARC, SPF, DKIM) is part of the Quick Wins in a full free audit, which returns AI fix instructions for every issue and a shareable PDF report.
Frequently asked questions
Is this DMARC checker free?
Yes, free with no signup, up to 15 checks per hour.
What does p=none mean?
p=none only monitors: it reports on failing mail but does not block spoofed messages. Real protection needs p=quarantine or p=reject.
Where do I add a DMARC record?
At your DNS host, as a TXT record at _dmarc.yourdomain.com starting with v=DMARC1.
Will DMARC block my own email?
It can if SPF and DKIM are not aligned first. Start at p=none, confirm your senders pass, then tighten the policy.
How does DMARC relate to SPF?
DMARC builds on SPF and DKIM to decide what to do with failing mail. Check your SPF with the SPF checker.
