What is DMARC?

DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol that protects your domain from being used in email spoofing attacks. It builds on SPF and DKIM to provide comprehensive email security.

Prevent Email Spoofing

Stop attackers from impersonating your domain and protect your brand reputation from phishing attacks.

Gain Email Visibility

See all email sources sending on behalf of your domain, including legitimate and malicious senders.

Detailed Reporting

Receive comprehensive reports on email authentication results and policy violations.

Compliance Requirements

Meet Microsoft, Google, and Yahoo's email authentication requirements to ensure deliverability.

DMARC Policy Levels

DMARC policies determine what happens to emails that fail authentication. Choose the right policy level based on your security needs and implementation readiness.

Starting Point

None (p=none)

Monitor mode - emails are delivered normally while gathering data on authentication results.

Intermediate

Quarantine (p=quarantine)

Failed messages are sent to spam/junk folders, reducing visibility of malicious emails.

Maximum Security

Reject (p=reject)

Failed messages are completely blocked, providing the strongest protection against spoofing.
