DMARC
CHECKER
Enter a domain to read its DMARC record. We fetch the policy published at _dmarc.yourdomain, parse every tag, and tell you in plain terms whether it is set to none (monitor only), quarantine, or reject, which is the difference between a domain that can be spoofed and one that cannot.
What is a DMARC Checker?
A DMARC checker is a free tool that looks up a domain’s DMARC record and reads its policy. It shows whether the policy is none (monitor only), quarantine or reject, which is the difference between a domain that can be spoofed and one that is protected, and parses every tag in the record.
How does a DMARC Checker work?
- 01We query the TXT record at _dmarc for the domain you enter.
- 02The policy and every tag (p, sp, pct, rua, aspf, adkim) are parsed.
- 03We flag a missing record or a weak p=none policy that leaves you exposed.
Frequently asked questions
What does a DMARC policy of none, quarantine or reject mean?
The policy tag (p=) tells receiving mail servers what to do with messages that fail authentication. p=none only monitors and reports, so spoofed mail still gets delivered; it is a starting point, not protection. p=quarantine sends failures to spam, and p=reject blocks them outright. A domain is only truly protected from spoofing at quarantine or reject.
Why do I need DMARC if I already have SPF and DKIM?
SPF and DKIM authenticate mail, but on their own they do not tell receivers what to do when a message fails, and they do not cover the visible From address a user actually sees. DMARC ties SPF and DKIM to that From domain and sets the enforcement policy. Gmail, Yahoo and Outlook now require DMARC for bulk senders.
My domain has no DMARC record. What should I do?
Start by publishing a p=none record with a rua address so you can collect reports and see who sends mail as your domain, then tighten to quarantine and reject once legitimate senders are aligned. A host or email provider that manages this for you removes most of the guesswork, and our email-focused hosting guides flag providers that do.
