DMARC is an email authentication protocol that helps prevent email spoofing, phishing, and other email-based attacks by providing domain owners with visibility and control over how their emails are authenticated and handled.
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that verifies the authenticity of the sender's domain. DMARC enables domain owners to specify how email servers should handle unauthenticated emails from their domain, improving email security.
Implementing DMARC can help protect your domain reputation by preventing unauthorized use of your domain in phishing or spoofing attacks. DMARC can improve email deliverability by reducing the risk of legitimate emails being marked as spam or rejected by recipient servers. Properly configuring DMARC policies, such as "p=reject" or "p=quarantine," can effectively block unauthorized emails and enhance email security.
