Summary
The number of DMARC reports received daily depends on the volume of email sent and the number of participating receivers, with at least one report per domain per day expected from each reporting organization or Mailbox Provider (MBP). Forensic (RUF) reports are rare, so the focus should be on aggregate (RUA) reports. Since these reports are in XML format, they require parsing. Effective management involves using automated tools, DMARC monitoring services, or custom scripts to parse and analyze the data. These tools help identify authentication issues, potential spoofing attempts, and unauthorized domain use, ultimately improving email deliverability and DMARC compliance. Regular analysis of these reports provides insights into an email's authentication ecosystem.
Key findings
- Report Volume: Daily DMARC report volume depends on email volume and reporting organizations/MBPs.
- Report Type: Forensic (RUF) reports are rare; focus on aggregate (RUA) reports.
- Report Format: DMARC reports are in XML format and require parsing.
- Purpose: DMARC reports aid in identifying authentication issues, spoofing, and unauthorized domain use.
Key considerations
- Automation: Use automated tools or custom scripts to manage and analyze DMARC reports efficiently.
- Monitoring Services: Consider using DMARC monitoring services for aggregation, analysis, and threat detection.
- Regular Analysis: Regularly analyze DMARC reports to ensure compliance and improve deliverability.
- Actionable Insights: Focus on extracting actionable insights from DMARC reports to address authentication and security issues.
- RUF: While aggregate is the most common form, setup both RUA and RUF reports for a full analysis
What email marketers say
10 marketer opinions
The volume of DMARC reports received daily depends on email volume and the number of participating receivers. While failure reports are infrequent, high-volume senders can expect a significant number of aggregate reports. Managing these reports effectively requires automated solutions. Options include using DMARC monitoring tools, creating dedicated mailboxes with parsing scripts, employing programming languages like Python for analysis, and setting up both aggregate and forensic reporting. Analyzing DMARC reports helps understand email handling, identify spoofing attempts, and refine authentication strategies.
Key opinions
- Report Volume: High-volume senders receive numerous daily DMARC reports.
- Failure Reports: DMARC failure reports are less frequent and only generated when alignment issues occur.
- Report Format: DMARC reports are in XML format and require parsing.
- Importance: DMARC reports are essential for understanding email handling and identifying spoofing.
- Aggregation: Using monitoring tools helps process and aggregate DMARC reports to create comprehensive overviews.
Key considerations
- Automated Tools: Implement automated systems to process, filter, and interpret DMARC report data efficiently.
- Monitoring Tools: Consider using DMARC monitoring tools or services for aggregation and analysis.
- Dedicated Mailbox: Create a dedicated mailbox for receiving DMARC reports.
- Reporting Type: Set up both aggregate (RUA) and, if supported, forensic (RUF) DMARC reporting.
- Parse Reports: Find ways to parse and visualise the reports so that the threats can easily be spotted
Marketer view
Marketer from Email Geeks suggests throwing DMARC reports into a database and sending daily or weekly updates, noting they are in XML format, making it relatively simple.

What the experts say
4 expert opinions
The expected volume of DMARC reports varies based on email volume and the number of mailbox providers (MBPs) involved. You should anticipate one daily report per MBP. Forensic (RUF) reports are rare, so focus on aggregate reports. Analyzing these reports, ideally with automated tools, is crucial for identifying authentication issues and potential unauthorized domain use, providing insights into your email ecosystem.
Key opinions
- Report Frequency: Expect one DMARC report daily per mailbox provider (MBP).
- RUF Reports: Forensic (RUF) reports are not commonly sent.
- Aggregate Reporting: DMARC Aggregate Reporting provides insights into authentication and configuration issues.
- Automated tools: Recommended in order to handle the number of emails and for easier review.
Key considerations
- Volume Management: Use automated tools to manage the volume of DMARC reports.
- Actionable Information: Focus on extracting actionable information from the reports.
- Regular Analysis: Conduct regular analysis to identify authentication errors.
- Unauthorised activity: The automated tools can help to identify unauthorised domain use
Expert view
Expert from Email Geeks explains that a recipient should get one DMARC report a day (on average) from each Mailbox Provider (MBP) they mail to, and an automated solution is recommended to manage the volume.
