Highlight Opt In
Clearly mark your emails so that customers are able to identify that they requested or subscribed to emails from your service.
Join the Junk Mail Reporting Program (JMRP)
The JMRP program allows you to see which of your emails Outlook.com users have marked as junk or unwanted mail. Reviewing the results in JMRP will provide to the most direct information on what characteristics of your email, customers, and ultimately SmartScreen®, consider to be unwanted. This helpful feedback mechanism allows you to ensure that mails being sent from your IP are not resulting in negative feedback that could impact your sending reputation. Being vigilant about users who mark your e-mail as unwanted or the types of messages that are being marked as unwanted can help you keep mailing lists updated with only interested users and modify future campaigns. In addition, monitoring user complaints can help you identify unintended mail traffic or detect a potentially compromised account sending unwanted mail to your customers.
Join the Smart Network Data Services program (SNDS)
The SNDS program provides data about traffic seen originating from your registered IP, such as mail volume and complaint rates. The data is built from the log files of the inbound mail machines and other servers at Outlook.com and Microsoft and represents factual information about the traffic from your mail servers to Outlook.com users.
