Summary
When seeking remediation from Cloudmark, providing specific data from monitoring platforms like 250ok (now SparkPost) is essential. Cloudmark requires clear evidence of good sending practices, proper list hygiene, and a commitment to best practices. This includes submitting the Cloudmark fingerprint data, typically found in email headers, and demonstrating low spam trap hits, minimal complaint rates, and robust email authentication. Additionally, showcasing improved inbox placement, healthy engagement metrics, and a clean sending history through 250ok's comprehensive reports significantly strengthens a remediation request.
Key findings
- Cloudmark Fingerprint Data: The 'x-authority-analysis' data, which represents a Cloudmark fingerprint, is crucial. Full email headers containing this data are essential for Cloudmark remediation requests, providing direct insight into their filtering reason.
- Spam Trap and Complaint Data: Zero or very low spam trap hits and consistently low user complaint rates, as monitored by 250ok, are paramount. Cloudmark relies heavily on this data to assess sender reputation and list hygiene.
- Authentication and Reputation: Evidence of robust authentication (SPF, DKIM, DMARC alignment) is vital. 250ok's historical data on IP and domain reputation, including a trend showing improving scores and consistent, legitimate sending patterns, builds a strong case for delisting.
- Engagement and Inbox Placement: Metrics on consistent open and click-through rates, alongside 250ok's seed list testing and inbox placement data for Cloudmark-protected ISPs, are critical. These demonstrate that mail is reaching the inbox and recipients are engaged.
- Bounce and Content Analysis: Detailed bounce classifications from 250ok, especially a reduction in 'unknown user' or hard bounces, indicate strong list cleaning. Additionally, reports showing low spam scores and successful content filtering help address content-based blocks from Cloudmark.
Key considerations
- Directing Requests: For issues relating to a Cloudmark fingerprint rather than an SMTP bounce, direct your remediation requests to the Cloudmark Authority support page. This ensures your request is handled by the correct team.
- Data Submission: When submitting a remediation request, include the Cloudmark fingerprint information, often found in 'x-authority-analysis' data, within the body of your support ticket. Additionally, always attach the full email headers as a text file; this is typically sufficient for submission and provides Cloudmark with essential context.
- Proving Good Practices: Cloudmark emphasizes evidence of good sending practices. Leverage 250ok data to demonstrate low spam complaint rates, minimal spam trap activity, proper email authentication (SPF, DKIM, DMARC), and a clean sending history. This validates that you have taken corrective actions and are not engaging in spammy behavior.
- Demonstrating Improvement: Cloudmark agents review historical sending behavior. Provide a clear report from 250ok showcasing a consistent pattern of low spam complaints, high engagement rates, and improved inbox placement post-issue resolution. Show a reduction in 'unknown user' bounces and consistent sending patterns, avoiding sudden spikes, as this proves commitment to clean practices.
- Content and List Health: Cloudmark can block based on content. Use 250ok's insights to show that recent emails have low spam scores and pass content filters. Also, demonstrate strong list hygiene with evidence of low hard bounce rates, overall healthy list scores, and a clear avoidance of known spam traps.
