About DMARC Lookup Tool

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that helps prevent email spoofing. This tool queries the _dmarc subdomain TXT record and validates the policy configuration. A properly configured DMARC record works with SPF and DKIM to protect your domain from unauthorized use. Recommended policy: quarantine or reject.
