Sender ID improves trust as adoption increases

BOSTON - Sender ID adoption has increased three times in size, accelerating to 8 million domains worldwide in just under a year, according to a Microsoft Corp. study that was released at last week's Authentication and Online Trust Summit.

The third annual study examined the effectiveness of Sender ID and e-mail authentication in helping counter deceptive e-mail. Windows Live Hotmail is now detecting 3.8 billion deceptive messages daily. Sender ID is helping to stop these deceptive messages, improving trust and confidence in e-mail communications for consumers and marketers alike.

"We have cut spam in inboxes by almost half, and we attribute this to reputation and the ability to link reputation to authentication," said John Scarrow, general manager at Microsoft.

The study also found that depending on the brand, between 40 percent and 98 percent of the e-mail sent to Windows Live Hotmail users is actually spoofed and fraudulent. In addition, Sender ID enabled domains detected 20 million forged messages daily. Reputable marketers who have adopted Sender ID have realized improved deliverability with up to 85 percent fewer messages mistakenly marked as spam in Windows Live Hotmail.

With spam increasing 40 percent in the past 12 months, it is claimed that spam in Hotmail users' inboxes has actually been reduced by 50 percent, of which Sender ID contributed 8 percent of that reduction.

Sender ID is helping major brands, Internet service providers and corporate networks worldwide improve trust and confidence in their e-mail communications. EBay and PayPal are increasingly relying on Sender ID to improve trust in communications with customers.

For example,, the world's largest domain name registrar, receives over 30 million e-mails for its e-mail customers daily. By implementing Sender ID, customers are receiving less spam and having fewer legitimate e-mails junked. More than 50,000 of's DNS customers are Sender ID-compliant today.

"If you are a good reputable sender, sending from a good server, we have reduced false positives by 87 percent," Mr. Scarrow said.
