New ways we're fighting spam in Hotmail
Hotmail's fight against spam has certainly come a long way in the last five years. Over the last several years we've made substantial investments in the research and development of sophisticated anti-spam technologies. SmartScreen is the collective name we use for a cloud-based set of technologies and algorithms that leverage machine learning and artificial intelligence to assign a “spam probability” score to each incoming message. This enables us to filter out over 98% of the spam sent to Hotmail inboxes, blocking 5.5 billion spam messages per day.  Microsoft utilizes SmartScreen across Hotmail, Microsoft Exchange, and Microsoft Forefront, bringing consumers the benefit of business-grade spam protection on Hotmail.
With the soon-to-be-released new version of Hotmail, we’ve added a number of innovative new spam fighting technologies that will further reduce the amount of spam in your Hotmail inbox. Here's a short video featuring myself, Dick Craddock, and John Scarrow telling you a bit about how Hotmail's latest innovations help bring you the best spam fighting on the web.
