DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is an email authentication protocol designed to protect against email spoofing, phishing, and other fraudulent activities. DMARC works by allowing domain owners to publish policies indicating how their emails should be authenticated, and what action should be taken if authentication fails.

A DMARC report is a feedback mechanism that provides detailed information about the delivery and authentication of emails sent from a specific domain. These reports are generated and sent by email receivers (e.g., ISPs, email providers) to the domain owner's specified email address. The primary purpose of DMARC reports is to help domain owners monitor and improve the authentication of their email traffic.

The data contained in DMARC reports typically includes:

  • Email Authentication Results

    Information about the success or failure of authentication mechanisms like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail).

  • Message Metadata

    Details about the emails, such as sender and recipient addresses, timestamps, the authentication status and server IPs.

  • Disposition and Policy Information

    Specifies the actions taken by the receiver based on the DMARC policy set by the domain owner (e.g., quarantine, reject, none).

DMARC reports are useful for several reasons, for example:

  • Visibility

    They provide insight into who is sending emails on behalf of a domain and whether those emails are passing authentication checks.

  • Security Improvement

    Domain owners can use the information to identify and prevent malicious activities such as phishing and spoofing attacks.

  • Policy Tuning

    Organizations can refine their DMARC policies based on the feedback to ensure legitimate emails are not mistakenly classified as fraudulent.

Analyzing DMARC reports manually can be challenging and time-consuming due to the volume of data. Use our free DMARC Report Analyzer Tool to keep track.

Aggregating and organizing data from DMARC reports is a crucial step in making sense of the vast amount of information generated by email authentication feedback. These reports typically contain data from various sources, including different email receivers, and can cover a range of time periods. Our DMARC analysis tool aggregates this disparate data into a centralized and coherent format, allowing domain owners to gain a holistic view of their email ecosystem. By consolidating information on authentication results, message metadata, and disposition policies, we create a comprehensive overview that simplifies the identification of patterns, trends, and potential issues.

  • Identify the servers which actually send emails on behalf on your domain
  • Pinpoint authentication and policy problems to prevent delivery failures
  • Prevent misclassification of your emails as spam or junk mail
  • Detect unauthorized use of your domain for spam, malware or phishing attacks
  • Improve your DKIM, SPF and DMARC records and policies
  • Visualize trends and patterns in authentication results

Please enter the host name for which DMARC reports are to be received and analyzed in the domain field. For example, if you send emails with the sender "service@myshop.com", enter "myshop.com" as the domain.

In the next step, you will be shown how to adjust your DMARC DNS record in order to have all future reports aggregated in our tool.
