What is DMARC and how does it improve email security?

DMARC is an email authentication protocol that protects your domain from spoofing and phishing attacks.

What does DMARC stand for?
DMARC stands for Domain-based Message Authentication, Reporting, and Conformance.

How does DMARC work?
It builds on SPF and DKIM to verify that emails are legitimate. If authentication fails, DMARC tells receiving servers what to do.

Why is DMARC important for businesses?
Without DMARC, attackers can send fake emails using your domain. This damages trust and can lead to fraud.

How do I implement DMARC?
You need to add a DMARC record in your DNS. Start with a monitoring policy, then move to quarantine or reject.

In summary, DMARC improves email security and protects your reputation.
