Smart Network Data Services

Welcome Outlook.com Smart Network Data Services
Deliverability to Outlook.com is based on your reputation. The Outlook.com Smart Network Data Services (SNDS) gives you the data you need to understand and improve your reputation at Outlook.com. But just looking at the data isn't enough! Maintaining a good reputation is a lot of work. You should use this data to keep your mailing lists clean and to monitor the IPs you control for unusual behavior. Reputation is always the responsibility of the sender. SNDS gives senders access to detailed data about individual IPs, and it also includes our Junk Email Reporting Program, which lets you receive reports when users junk your messages. Now you can view IP data and manage feedback loop settings from one convenient website.

Updates

Upcoming changes

We are updating the ARF feedback format to include only the original message headers from the complaint email, plus selected authentication headers (for example, Authentication‑Results and Received‑SPF). The sender address will be redacted. Previously, the ARF included the full complaint email body, under the new format, that content is no longer appended.

SNDS will move to a new, more secure URL.

Automated report links will expire after 30 days to reduce risk and enhance security.

JMRP feeds that are not linked to SNDS accounts will be removed. You will be asked to create new ones from your SNDS account and keep the network access up-to-date.

Getting started
To access SNDS, please log in with a Microsoft Account and then request access to the IPs for which you are responsible. You'll be taken through a simple authorization process, and then you'll soon have access to a wealth of information about those IPs.

Help! I have a problem sending mail to Outlook.com
Building & maintaining good reputation is a long-term proposition. The data on this site can help you do that, but if you have an urgent deliverability issue please have the person most familiar with the issue and your email infrastructure contact sender support.

Other Benefits
SNDS is useful for far more than just monitoring email reputation. It can help IP owners to detect compromised servers, malware, viruses, and botnets. We help network administrators detect these problems so that they can clean them up and make the internet a safer place.
