Examine your domain's DMARC configuration instantly. Our validator analyses your email authentication policy, verifies alignment parameters, and confirms reporting destinations to safeguard your organisation against email fraud and brand impersonation.
Simply enter your domain name below and receive a comprehensive breakdown of your DMARC implementation status.
DMARC (Domain-based Message Authentication, Reporting & Conformance) serves as a critical email security framework that instructs recipient mail servers how to handle messages that fail authentication checks.
This protocol works alongside SPF and DKIM technologies to create a robust defence against email spoofing, phishing attacks, and unauthorised use of your domain name in fraudulent communications.
When properly configured, DMARC provides detailed reporting on all email sent using your domain, giving you visibility into both legitimate and malicious activity.
A properly structured DMARC record typically contains several key elements:
These components work together to create a comprehensive email authentication strategy tailored to your organisation's needs.
Regular DMARC record verification becomes essential during several key scenarios:
Proactive monitoring ensures your email authentication remains effective and doesn't inadvertently block legitimate communications.
How can I verify my domain has DMARC configured?
Use our checker tool with your domain name. A valid DMARC record will be published at the _dmarc subdomain of your organisation's domain.
What's the difference between policy enforcement levels?
The three policy levels offer escalating protection: 'none' provides monitoring without action, 'quarantine' flags suspicious messages for spam filtering, whilst 'reject' completely blocks authentication failures.
Is SPF and DKIM setup required before DMARC?
Absolutely. DMARC depends on either SPF or DKIM (preferably both) passing authentication and aligning with your visible sender domain for legitimate email validation.
Why might my DMARC record exist but not function properly?
Common issues include incorrect DNS publication location, syntax errors in record tags, misaligned SPF/DKIM configuration, or reporting addresses that cannot receive DMARC data.
