Subscribing to Microsoft JMRP and SNDS


This article explains Microsoft’s JMRP (Junk Mail Reporting Partner Program) and SNDS (Smart Network Data Services), as well as the means to subscribe.

What is JMRP?

The JMRP (Junk Mail Reporting Partner Program) by Microsoft Hotmail/Outlook is a junk mail reporting service developed for commercial email senders and administrators who use an SMTP (Simple Mail Transfer Protocol) service. It provides reports on emails sent from a server and marked as junk by Hotmail clients. Tracking user complaints can help to identify sources of junk mail or to detect a potentially hacked account that is generating spam.

What is SNDS?

SNDS (Smart Network Data Services) allows a subscriber to access data on the email traffic that it sends to Hotmail/Outlook (e.g., volume of emails sent, number of complaints, etc.) via an online interface, for each of its IP addresses.

Following the migration of Hotmail to Outlook, Microsoft merged JMRP and SNDS in the same interface.
