What is DMARC and Why It Matters

Understanding DMARC Authentication

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that helps protect your domain from email spoofing, phishing scams, and other email-based threats. It builds upon SPF and DKIM protocols to provide a comprehensive email authentication solution.

Key Benefits of DMARC

  • Prevents email spoofing and phishing attacks
  • Improves email deliverability rates
  • Provides visibility into email authentication
  • Protects your brand reputation
  • Ensures compliance with email security standards

How DMARC Works

  1. Publishes a DMARC record in your DNS
  2. Receiving servers check your DMARC policy
  3. Validates SPF and DKIM alignment
  4. Applies your specified policy (none/quarantine/reject)
  5. Sends detailed reports about authentication results
