Quick Answer
What does Microsoft SNDS help you monitor?
Microsoft SNDS shows how Microsoft is viewing traffic from your sending IPs. You can use it to review blocked status, spam filtering signals, trap hits, complaint indicators, traffic patterns, and trends over time.
Monitoring Your Sending Reputation Before Problems Start
Email reputation problems can begin before a noticeable drop in deliverability appears.
Microsoft SNDS gives you visibility into how Microsoft services view traffic from your sending IP. That information can help you identify spam filtering, complaints, trap hits, blocks, or unusual traffic patterns before they become larger problems.
Reviewing these signals regularly can make it easier to identify whether a deliverability issue is connected to list quality, content, sending volume, or IP reputation.
Use SNDS as a Microsoft inbox health check
SNDS is especially useful when Outlook, Hotmail, or other Microsoft inbox performance changes suddenly or while you are warming up a new sending setup.
Microsoft SNDS at a Glance
Before You Begin
Identify the sending IP and sending route you want to monitor before reviewing SNDS data.
- Identify the sending IP connected to the email route you are reviewing.
- Note whether deliverability has recently changed for Microsoft inboxes.
- Review recent list uploads, volume increases, or campaign changes that may affect reputation.
- Be prepared to compare SNDS trends before and after any corrective changes.
What SNDS Helps You Monitor
Microsoft SNDS reports show how Microsoft is seeing traffic from your sending IPs. This can be especially useful when troubleshooting deliverability or warming up a new sending configuration.
Blocked Status
Check whether the sending IP is currently blocked.
Spam Filtering Signals
Review indicators that Microsoft may be filtering your mail.
Trap Hits
Identify possible spam trap interactions that may indicate list-quality problems.
Complaint Indicators
Watch for reputation signals that can reduce inbox placement.
Traffic Consistency
Review volume patterns that may appear suspicious when sending increases suddenly.
CSV Exports
Export data so you can compare reputation and traffic changes over time.
Why This Matters
Improve Deliverability
Identify risky signals before Microsoft blocks your IP.
Protect Reputation
Catch trap hits and list-quality problems earlier.
Send Smarter
Use trend data to guide warm-up and future volume increases.
Reduce Troubleshooting Time
Reputation signals can help narrow problems down to list quality, content, or sending volume.
How to Use Microsoft SNDS in BizStackPro
Step 1: Open the SNDS Dashboard

Step 2: Select the IP You Want to Monitor
If you have multiple sending IPs, select the IP associated with the sending route you want to review.
Step 3: Review the Key Fields
Focus on Blocked Status, spam or filtering indicators, trap hits, and complaint-related signals.
Step 4: Export a CSV Report
Export the data so you can compare results before and after cleaning a list, reducing sending speed, or changing email content.
Check SNDS after major sending changes
Review the dashboard after a large list upload, a new sending domain, a significant volume increase, or a major campaign change.
Interpreting Common Red Flags
Start with list quality and sending speed
When deliverability drops, cleaning the audience and slowing down sending can often address the underlying risk before making larger technical changes.
Handling IP Reputation Issues
If SNDS shows reputation problems, reduce risk first and then rebuild trust gradually.
