DMARC Lookup
Enter a domain to fetch its DMARC record — the policy that tells receivers what to do with mail that fails SPF and DKIM.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) lives at _dmarc.yourdomain.com and builds on SPF and DKIM. It tells receiving servers what to do when authentication fails — nothing (p=none), quarantine to spam (p=quarantine), or reject outright (p=reject) — and where to send aggregate reports. Gmail and Yahoo now require DMARC for bulk senders.
Common policies
p=none— monitor only; a starting point, not a destinationp=quarantine— failed mail goes to spamp=reject— failed mail is refused; the strongest anti-spoofing stance
DMARC guards your domain against spoofing. High bounce rates hurt you with the same inbox providers — clean your list with SkipBounce to keep both signals healthy.
