DMARC Checker
Enter a domain to check its DMARC record at _dmarc, including policy and reporting addresses.
About this tool
DMARC works alongside SPF and DKIM to help prevent email spoofing. This checks the record's basic structure and common configuration gaps — it does not verify actual mail delivery or DKIM alignment.
Frequently Asked Questions
- What does this tool show?
- Whether a DMARC record exists at _dmarc, its policy, and its reporting (rua/ruf) addresses.
- What does policy p=none mean?
- DMARC is in monitoring mode only and won't affect mail delivery — this is flagged so you know to review it.
- Does this verify actual mail delivery or DKIM?
- No, it checks the record's structure and common configuration gaps, not live mail delivery or DKIM alignment.
