DMARC Checker
Enter your domain to read your live DMARC policy and find out whether it's actually protecting you.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receivers what to do when a message fails SPF or DKIM, and where to send aggregate reports. It ties your authentication together and protects your domain from spoofing.
What does p=none / quarantine / reject mean?
p=none only monitors (no enforcement) — a safe starting point. p=quarantine sends failing mail to spam. p=reject blocks it outright. Move up the ladder as your authentication becomes consistent. This tool flags p=none as 'weak' so you know there's room to harden.
Where does the DMARC record live?
As a TXT record at _dmarc.yourdomain.com starting with v=DMARC1. We read it live from DNS and, if it's missing or set to monitor-only, suggest a stronger record you can copy.
