Free DMARC Checker

Check if your domain has a DMARC policy configured. DMARC prevents spammers from spoofing your domain in phishing emails.

What is DMARC?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that tells receiving email servers what to do when an email claiming to be from your domain fails SPF or DKIM checks. It helps protect your brand from email spoofing and phishing attacks.

Why You Need DMARC

Prevent domain spoofing - Stop attackers from sending fake emails from your domain
Improve email deliverability - Legitimate emails are less likely to land in spam
Get visibility - Reports show who is sending email using your domain
Protect your brand - Customers trust emails from your domain
