NEW YORK, NY, August 10, 2005 - Return Path, Inc. announced today that it will incorporate email reputation data from Mailshell into its Sender Score system, the first reputation management system for email senders and receivers. Sender Score is currently in Beta, and will officially launch later this quarter. The data will come from Mailshell's SpamCompiler engine, which optimizes, compiles and executes more than one million filter checks in a fraction of a second. Mailshell licenses the SpamCompiler engine to companies looking to add best-of-breed spam filtering to their own products.
"Mailshell's global network of OEMs provides a rich, diverse and current source of email reputation data," says George Bilbrey, vice president and general manager of Return Path's Delivery Assurance Solutions. "This data will further enhance the scoring platform for Sender Score, giving both receivers and senders the information they need to make email program improvements."
Mailshell's system quantifies reputation via advanced statistical models. This reputation-based analysis creates de facto advanced 'phishing' detection, along with protection from fraud and other blended threats. By focusing on reputation, Mailshell is also able to deploy a language-agnostic statistics-based solution that catches foreign language spam more accurately than content-focused solutions.
Mailshell also plans to query Sender Score data in its filtering platform. "By contributing our reputation data to Return Path's Sender Score, we add value to the system, making it a more useful rating service for all parties," said Tonny Yu, CEO of Mailshell. "We also believe that Sender Score can be another valuable tool for differentiating between legitimate commercial email and spam."
Sender Score aggregates 60 different data criteria from around the Internet that quantify a mailer's reputation, drawing data from a diverse sample of more than 40 million e-mail boxes covered by filtering companies and ISPs. Sender Score includes multiple reputation indices that track variables such as complaint data, e-mail send volume, unknown user volume, security practices, identity stability, and unsubscribe behavior - all of which factor into a statistically modeled score that compares individual mailers against the whole sample using a standardized set of best practices. The scores will be transparent and available for anyone to review at full launch, though underlying program data will only be available to Return Path clients and partners.
Sender Score rounds out Return Path's Delivery Assurance Solutions set, joining Return Path's delivery monitoring tools, consulting, and the Bonded Sender e-mail accreditation program.
