Reading Your First DMARC Reports

"You've enabled Domain-based Message Authentication, Reporting, and Conformance (DMARC) to protect your brand from phishing and spoofing-an important first step for any business that sends emails. Good work! Now, you're receiving technical reports filled with data. They reveal essential information about your email ecosystem, including potential email threats and authentication results. Learn how to cut through the noise and turn data into actionable insights to make the most of your first DMARC report."

"DMARC tells receiving mail servers how to handle emails that claim to be from your domain but fail authentication. It helps prevent phishing and spoofing attacks. They also provide visibility into your email ecosystem through detailed aggregate reports. DMARC aggregate reports don't contain sensitive message content, but they offer an overview of sent emails claiming to be from your domain. They show: Whether emails passed DMARC authentication. Which servers sent them according to source IP/sending domain. What actions did receiving mail servers take based on your DMARC policy."

DMARC provides receiving mail servers instructions for handling emails that claim to be from a domain but fail authentication and helps prevent phishing and spoofing. Aggregate reports summarize authentication outcomes, sending sources by IP or domain, and actions taken based on policy. Reports omit message content while revealing legitimate senders that may be misconfigured and unauthorized senders. Analysis of reports enables identification of failing legitimate emails, detection of spoofing attempts, and refinement of SPF, DKIM, and sending infrastructure. Proactive remediation of findings improves deliverability and allows gradual enforcement of DMARC policies to protect brand reputation and reduce abuse.
