Question 1

Is the DMARC analyzer free?

Accepted Answer

Yes. Analyzing a domain's DMARC record is free and doesn't require an account or email address.

Question 2

What does the DMARC analyzer check?

Accepted Answer

It parses the domain's published DMARC record and evaluates policy enforcement (p=), subdomain policy, DKIM and SPF alignment mode, aggregate and forensic reporting configuration, and flags deprecated tags, missing rua= addresses, and other RFC 7489 issues.

Question 3

Does analyzing a domain change anything in its DNS?

Accepted Answer

No. The analyzer only reads the existing public DMARC TXT record — it never writes or modifies anything, and works on any domain, not just ones you own.
