Cloudmark's 100 Million Users Protected by LashBack's "UnsubSafe" Technology

LashBack Gives Cloudmark Access to Its Automated Safe Unsubscribe Service

SAINT LOUIS, MO -- (MARKET WIRE) -- October 17, 2006 -- Today, LashBack, an email reputation provider, announced that messaging security provider Cloudmark has incorporated its UnsubSafe™ technology into their Authority Safe Unsubscribe feature, which is part of its secure messaging suite of solutions for service providers. The partnership ensures that email users' unsubscribe requests from email newsletters are granted and that they are removed from future mailing lists.

Cloudmark introduced its "Safe Unsubscribe" feature this summer to providers of messaging services, including Internet and mobile service providers, to offer flexible options for safely unsubscribing their end users from newsletters. Service providers may opt to offer a "Safe Unsubscribe" option on their user interface that is powered by the Cloudmark Network Feedback System, or service providers may also opt to participate in the Cloudmark Safe Unsubscribe service that automatically unsubscribes users when they hit "block spam." A frustration for service providers and legitimate newsletter providers alike, subscribers simply click the "spam" button rather than unsubscribe when they fear doing so may legitimize a spammer's email list. Cloudmark's comprehensive unsubscribe solution relies on Cloudmark Global Threat System, Trust Evaluation System, Fingerprinting Algorithm and now also incorporates LashBack's Safe Unsubscribe Automation Service.

The LashBack UnsubSafe program rewards trustworthy senders with several program benefits, including decreased complaints and visual recognition at the inbox. In order to be qualified for UnsubSafe, processing senders must maintain an UnsubScore of 90 or better, register for Cloudmark's Ratings program and include a list unsubscribe header within each message. Additionally, LashBack's UnsubMonitor is available to newsletter mailers. It is the only compliance monitoring service that enables commercial mailers to monitor and proactively address actual consumer unsubscribe requests in real-time. UnsubMonitor is a complete solution for commercial mailers to monitor the unsubscribe requirements of CAN-SPAM.

Already in 50 top service provider networks around the world, Cloudmark continually evolves its technology to prevent impending threats to network infrastructure, lower the costs associated with rising messaging abuse, and increase customer satisfaction.
