Summary
When you receive an automated reply from Microsoft's SNDS IP review, understand this is a standard confirmation. Wait for the subsequent manual review by Microsoft. Experts advise *against* replying to the auto-reply; instead, respond to the human-reviewed follow-up. Proactively monitor your IP's SNDS reputation for complaint rate changes. If there's no follow-up within 48 hours, resubmit the request with detailed information. Check blocklists regularly. Utilize SNDS with JMRP for a comprehensive reputation view. Expect 1-2 days for investigation if blocked. Properly handle bounces and review SNDS data to address high complaint rates and spam traps, but remember SNDS is one data point; use other monitoring services too, especially the Outlook.com FBL for accurate complaint feedback.
