DMARC Checker
Look up a domain's DMARC policy and see how it protects against email spoofing and phishing.
What is DMARC?
Domain-based Message Authentication, Reporting and Conformance (DMARC) is an email authentication protocol. It builds on SPF and DKIM to tell receiving servers what to do with emails that fail authentication — reject, quarantine, or do nothing. It also enables reporting back to domain owners about email authentication results.
