DMARC Checker
Check your domain's DMARC record and policy. DMARC ties SPF and DKIM together, tells receivers what to do with mail that fails, and is now required by Gmail and Yahoo for bulk senders.

This tool reads your domain's public DMARC (TXT) record at _dmarc.yourdomain at the moment of the check. Results reflect current public DNS and can be affected by caching and propagation (up to 24-48 hours). Guidance is general and not a substitute for your provider's official instructions. We don't store the domains you check.What is DMARC?
DMARC builds on SPF and DKIM. It tells receivers what to do with mail that claims to be from your domain but fails authentication, and sends you reports showing who is sending as you.
Policies
p=none- monitor only.p=quarantine- failing mail to spam.p=reject- failing mail blocked (strongest).rua=- where aggregate reports are sent.
Safe rollout
- Publish
v=DMARC1; p=none; rua=mailto:you@yourdomain. - Review reports; confirm senders pass SPF or DKIM aligned.
- Move to
p=quarantine, thenp=reject.
