How to interpret Microsoft SNDS data?

Microsoft SNDS (Smart Network Data Services) provides IP-level reputation data for Outlook, Hotmail, and Live.com properties:

Traffic light indicators show reputation status. Green means healthy. Yellow indicates concerns. Red signals serious problems requiring immediate attention.

Complaint rates display the percentage of recipients marking your mail as junk. Rates should stay well below 0.1%.

Spam trap hits reveal whether you are sending to Microsoft's spamtrap network, indicating list hygiene problems.

Sample data shows which messages triggered complaints, helping identify problematic campaigns.

SNDS focuses on IP reputation, which Microsoft still weighs heavily in filtering decisions.

SNDS is Microsoft's inspection report on your vessels. The traffic lights indicate your current standing, and the detailed data explains why authorities assigned that rating.
