DMARC (Domain-based Message Authentication, Reporting, and Conformance) is crucial for protecting your domain from email spoofing and phishing attacks. Without DMARC, malicious actors can impersonate your domain to send fraudulent emails, damaging your brand reputation and trustworthiness. DMARC relies heavily on SPF authentication and DKIM for proper functionality.
By implementing DMARC, you ensure that only authorized senders can use your domain, while unauthorized emails are either flagged or rejected. Additionally, DMARC provides visibility into your email authentication status through reports, allowing you to monitor and improve your email security posture.
