DMARC Checker
Looks up a domain's DMARC policy and reporting settings.
Frequently asked questions
What is DMARC?
DMARC tells receiving mail servers what to do with messages that fail SPF or DKIM checks — reject them, quarantine them, or let them through — and can request reports back to the domain owner. This checker shows the policy, how strict it is, and whether reporting is configured.
Is this free to use?
Yes, completely free, with no signup or account required.
Do you store the domains I check?
No. Each check is a live, one-time DNS lookup — we don't save what you type in.
