Verify DMARC email authentication policy for any domain
Enter a domain to check its DMARC record
DMARC Record Checker is a powerful free online tool that checks and validates DMARC (Domain-based Message Authentication, Reporting & Conformance) records for any domain. Verify your email security policy, check policy strength, and ensure proper configuration.
The DMARC Record Checker is a free online tool available on AllToolHub that fetches and validates DMARC records for any domain. DMARC builds on SPF and DKIM to provide domain-level email authentication, allowing domain owners to publish policies about how to handle unauthenticated emails.
Enter a domain name and click Check DMARC. The tool queries the _dmarc.DOMAIN TXT record via Google DNS API, parses all DMARC tags (v, p, sp, rua, ruf, pct, adkim, aspf, fo), and provides human-readable explanations. It also evaluates policy strength and warns about common issues.
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that builds on SPF and DKIM. It lets domain owners publish policies about how receiving servers should handle unauthenticated emails.
There are three policy levels: none (monitor only, no action), quarantine (move to spam), and reject (block entirely). Reject is the strongest policy.
The rua tag specifies the email address where aggregate DMARC reports should be sent. These reports help you monitor authentication results for your domain.
