Today, at the third annual Authentication and Online Trust Summit, Microsoft Corp. published results culminating from a two-year-long study on the effectiveness of Sender ID Framework e-mail authentication in helping counter deceptive e-mail. With Windows Live™ Hotmail® alone detecting over 3.8 billion deceptive messages daily, Sender ID is helping provide real results as a cost-effective solution. Sender ID has enjoyed a threefold increase in adoption, accelerating to 8 million domains worldwide in just under a year.* This technology is helping to realize the promise established by the industry and government agencies to improve trust and confidence in e-mail communications for consumers and marketers alike.

“Spam and phishing attacks continue to undermine user productivity, trust and online confidence. The business value of Sender ID is now providing tangible benefits,” said Ryan Hamlin, general manager of the Technology Care and Safety Group at Microsoft. “Widespread adoption of the Sender ID Framework, continued collaboration with industry, businesses and governments, and a commitment to user education are all promising steps toward protecting the inbox. To help stem this tide of deceptive e-mail, businesses must implement today to protect their brand, their customers and their employees.”
