What is DMARC?
DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol that helps protect your domain from email spoofing and phishing attacks. It works alongside SPF and DKIM to ensure only authorized mail servers can send emails on behalf of your domain.
