DMARC Checker
Check DMARC policy, reporting tags and enforcement readiness for your domain email.
Run the check
Enter a public target. Checks are a point-in-time sample; private and internal addresses are blocked.
Why it matters
DMARC tells receivers how to handle mail that fails SPF and DKIM checks.
Plain-English examples
- Check _dmarc.example.com before enforcing policy
Recommended fixes
- Start with reporting, then move toward quarantine or reject
- Add rua reporting to monitor failures
Understanding the result
Use findings as a starting point, confirm the intended configuration with your provider, and retest after a change. A successful check does not guarantee security, delivery, uptime or search rankings. Results depend on public DNS and what the server exposes at the time of the check.
