DMARC Report Received from Mailchimp: What You Need to Know
January 31, 2025 | 3 min read
Understanding DMARC Reports from Mailchimp
Mailchimp is a widely used platform for email marketing, making it essential for users to ensure proper email authentication to maintain deliverability and protect their domain from phishing or spoofing. DMARC (Domain-based Message Authentication, Reporting & Conformance) reports from Mailchimp provide valuable data on how recipient servers process your emails based on SPF and DKIM checks. Monitoring and acting on these reports helps ensure email security and a strong sender reputation.
Key Components of Mailchimp DMARC Reports:
1. Source IP Address: This shows the IP address used by Mailchimp to send your email. Tracking this helps verify that emails are originating from authorized Mailchimp IP addresses, preventing unauthorized sources from sending emails on behalf of your domain.
2. DKIM Alignment Results: This field indicates whether the DKIM signature matches the domain in the “From” header. Mailchimp supports DKIM signing, and ensuring alignment is crucial for passing DMARC checks.
3. SPF Alignment Results: Verifies whether the sending IP from Mailchimp is authorized by your domain’s SPF record. SPF alignment is essential for preventing unauthorized use of your domain.
4. Disposition: Tells you how the recipient server treated the message (e.g., delivered, quarantined, or rejected) based on your DMARC policy settings.
5. Message Count: Displays the number of emails sent from a particular IP, which can help you monitor email campaigns and identify suspicious activity or potential abuse.
Automating DMARC Parsing for Mailchimp
Given the high volume of marketing emails sent through Mailchimp, manually parsing DMARC XML reports can be overwhelming. Automating the process with tools like Skysnag helps streamline DMARC management, making it easier to monitor and maintain email security.
– Data Aggregation from Multiple Providers: If you’re using Mailchimp alongside other email providers, Skysnag aggregates DMARC reports from all sources into one unified view. This is especially helpful for organizations running multiple marketing platforms or email services.
– Visualizing Key Metrics: Skysnag translates raw DMARC XML data from Mailchimp into visual dashboards, presenting critical metrics such as DKIM/SPF pass rates, unauthorized email attempts, and which IP addresses are actively sending emails. This makes it easier to monitor Mailchimp campaign performance and identify potential security issues.
– Automated Incident Response: Skysnag enables real-time alerts for failed DMARC checks. If emails sent through Mailchimp fail SPF or DKIM alignment, you are notified immediately so you can resolve misconfigurations or block suspicious IPs before they impact deliverability or security.
– Forensic Reporting: Some DMARC reports include deeper forensic data, such as full email headers for failed authentication. For Mailchimp users, this information can help pinpoint why certain emails aren’t passing checks and improve email flow and security.
Ensuring Proper DMARC Alignment with Mailchimp
For optimal DMARC effectiveness, it’s essential that emails sent through Mailchimp are properly aligned with both DKIM and SPF. Misalignment between these mechanisms and the “From” domain can cause emails to be quarantined or rejected by recipient servers, even if they pass other checks. Ensuring alignment protects your email marketing campaigns from being flagged or failing to reach your audience.
Skysnag’s Custom Solutions for Mailchimp:
– DKIM Key Management: Skysnag ensures that Mailchimp’s DKIM keys are correctly aligned with your domain. Any issues with DKIM alignment or outdated keys are flagged, allowing you to maintain smooth and consistent delivery of authenticated emails.
– SPF Flattening: When using multiple services like Mailchimp, SPF records can become too complex, leading to DNS lookup issues. Skysnag automates SPF flattening to keep your SPF records optimized, preventing DNS lookup failures that could affect Mailchimp email authentication.
– Policy Recommendations: Based on analysis of your Mailchimp DMARC reports, Skysnag provides recommendations for adjusting your DMARC policy. This could involve transitioning from “none” to stricter modes like “quarantine” or “reject” to better protect your domain from spoofing and phishing attacks.
By automating DMARC parsing and providing tailored solutions for Mailchimp, tools like Skysnag help ensure that your marketing emails are properly authenticated, securely delivered, and free from potential domain abuse, while maximizing email deliverability and protecting your sender reputation.
