Services for Senders and ISPs

Sender Solutions

Email abuse, junk email, and fraudulent emails (phishing) continue to burden the entire email ecosystem. To help build back consumer trust in the use of email, Microsoft has put in place various policies and technologies to help protect our consumers. However, Microsoft understands that legitimate email senders should not be negatively affected. Therefore, we have established a suite of services to help senders improve their deliverability to Outlook.com consumers by proactively managing their sending reputation.
Below is an overview of services that can benefit your organization including links for more information:

 ISP Solutions

Microsoft understands that no single organization can change or eliminate email abuse on its own. Internet Service Providers (ISPs) play a major role in identifying and curbing abuse as they host millions of email accounts around the world. Therefore, we have built some services to help ISPs gain a good understanding of the type of traffic originating from their networks and reaching Outlook.com customers. ISPs can then use this data to help stop abusive activity (junk email, phishing, etc.) on their networks in order to reduce overall costs and proactively manage their reputation.
