DMARC record checker
DMARC tells receiving mail servers what to do with messages that claim to be from your domain but fail SPF or DKIM: deliver, send to spam or reject. This checker finds the _dmarc record (or the parent domain's record when a subdomain has none), validates every tag, counts how many records are published and shows which policy actually applies to the domain you entered.
Cómo usar
- Enter a domain or an e-mail address — we take the part after @
- Review the score, the effective policy and the findings
- Fix the DNS record, then check SPF and DKIM with the links above the result
