Understanding DMARC Report Data

DMARC: A Brief Overview

DMARC, or Domain-Based Message Authentication, Reporting, and Conformance, is an email authentication protocol designed to prevent email spoofing. By implementing DMARC, domain owners can protect their brand’s identity and reputation, increase email deliverability, and reduce the risk of phishing attempts.

DMARC works by aligning the domain’s DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework) records with the email message’s “From” header. If the alignment fails, DMARC can instruct the receiving email server to reject or quarantine the message, depending on the domain’s DMARC policy.

Understanding DMARC Reports

When a domain owner implements DMARC on their domain, they start receiving DMARC reports from receiving email servers. These reports contain detailed information about the domain’s email traffic and allow the domain owner to analyze and improve their DMARC implementation.

DMARC reports are XML files that contain various data points, such as the number of SPF and DKIM failures, the email sources used to send messages, and the email providers that received the messages. The data can be analyzed to identify trends in email traffic, detect unauthorized usage of the domain, and troubleshoot DMARC implementation issues.

Interpreting DMARC Report Data

Interpreting DMARC report data can be challenging, especially for domain owners who are new to DMARC. Here are a few tips to help make sense of the data:

  • Focus on the aggregate reports first: DMARC reports can contain both aggregate and forensic data. Aggregate reports provide an overview of the domain’s email traffic, while forensic reports contain detailed information about individual email messages. Start by analyzing the aggregate reports as they provide a higher-level view of the domain’s email traffic.
  • Look for patterns in the data: Analyze the DMARC report data over time to identify trends in the domain’s email traffic. Look for changes in email volume, email sources, and email providers. Patterns in the data can provide insights into how the domain’s email traffic is evolving and where improvements can be made to the DMARC implementation.
  • Pay attention to authentication failures: DMARC reports contain information about SPF and DKIM authentication failures. Analyze this information to identify the sources of authentication failures and prioritize remediation efforts. Reducing authentication failures can improve email deliverability and reduce the risk of domain spoofing.
  • Using DMARC Analytics Tools

    There are several DMARC analytics tools available that can help domain owners analyze DMARC report data more efficiently. These tools provide visualization and analysis features that can make interpreting DMARC report data more accessible.
