Frequently Asked Questions

Find Quick Answers

What is a DMARC record?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that helps domain owners protect their domains from unauthorized use (email spoofing). A DMARC record is a DNS TXT record that specifies how email receivers should handle emails that fail SPF and DKIM checks.

What format should the DMARC record be in?

DMARC records should be in the standard DNS TXT format starting with 'v=DMARC1;' followed by tag-value pairs separated by semicolons. Example: v=DMARC1; p=none; rua=mailto:[email protected]; ruf=mailto:[email protected];

What are the required tags in a DMARC record?

The only required tag is 'v=DMARC1' (the version). However, a policy tag (p=none, p=quarantine, or p=reject) is strongly recommended. Other important tags include rua (aggregate reports) and ruf (forensic reports).

Can I analyze multiple DMARC records at once?

No, this tool analyzes one DMARC record at a time. Each analysis provides detailed validation and recommendations for a single record.

Is my DMARC data stored or shared?

No, all processing happens locally in your browser. No data is sent to any server or stored anywhere.
