What should I do if my IP is suspended from Validity Certification due to high complaint rates?

Summary

If your IP is suspended from Validity Certification due to high complaint rates, the key is a comprehensive approach focusing on both immediate action and long-term improvements. Experts recommend addressing the root cause of the complaints by analyzing recent campaigns, improving list hygiene (removing inactive, bounced, and unsubscribed users), ensuring clear opt-in processes and honoring unsubscriptions. Sending relevant content to engaged subscribers is crucial, and segmentation of your audience can help achieve this. Monitor your sender reputation using tools like Validity Everest and Google Postmaster Tools, and ensure you're properly processing complaint feedback loops to remove complainers. Maintain consistent sending volumes and properly authenticate your emails with SPF, DKIM, and DMARC. Continuing to send (carefully) to engaged users can help restore your reputation by providing data for improvement. Consider requesting mitigation from Microsoft if you believe the suspension is an error, but only after addressing these issues.
