DMARC lookup
🌐
Honest note: DMARC requires a DNS query to
_dmarc.domain via our lookup API. Not an offline file tool.Understand DMARC policy tags
DMARC tells receivers what to do when SPF/DKIM alignment fails: p=none (monitor), quarantine, or reject. This tool fetches the record and explains the policy tag in plain language.
Frequently asked questions
Where is DMARC published?
Usually a TXT record at _dmarc.example.com.
Is none bad?
none is fine for monitoring; move to quarantine/reject when ready.
Does this check rua reports?
It shows rua/ruf tags if present but does not process aggregate reports.
