yesmail.com and AdTools to Integrate Multimedia and "Shop-Within" Technology into Email Marketing Applications

Nov. 16, 1999--

Companies to co-develop customized tools for enhanced one-to-one communications

yesmail.com (NASDAQ: YESM), the leading outsourcer of permission email marketing technologies and services, announced today that it has partnered with AdTools Inc. to integrate its ice9(tm) multimedia technology, featuring DeskShop(tm), into YesMail's direct email products.

Through this agreement YesMail will provide marketers the ability to deliver rich media messages that enable recipients to browse, select and place products into a shopping cart offline, prior to linking to the marketer's Web site for final purchase. By tightly integrating AdTools' technology with the solutions and service offerings delivered through YesMail, the companies will be providing enhanced media advertising beyond what has been offered in the traditional email marketing medium to date.

"With AdTools yesmail.com is utilizing leading interactive technology to take ecommerce via permission email to the next level," said Dave Tolmie, CEO of yesmail.com. "We're excited about the advantages this partnership provides yesmail.com as a company and the benefits it will create for our clients."

AdTools' ice9 product line delivers an interactive multimedia brochure that incorporates graphics, animation, and digital sound within a self-executable file, requiring no plug-ins or installations to open or view. ice9 allows the end user to signup or shop for products and services directly from the desktop. This advanced technology allows marketers to rapidly deploy multimedia content and decreases the bandwidth demands on their Web site by minimizing traffic from non-buyers. YesMail will also utilize AdTools' MessageMates(tm) technology -- emailable windowless desktop cartoons.

New YesMail products created with these technologies can be easily passed along giving messages "continued life" and increasing the overall reach for marketers. These messages can also be tracked through pass-along and integrated into a single yesmail.com report with initial click through and web site conversion data.

Peder Jungck, chief technology officer of yesmail.com commented, "The ice9 product line that AdTools has developed is very sophisticated multimedia technology. With ice9 we'll be able to deliver enhanced messaging to YesMail clients immediately, and will begin working together to develop customized proprietary tools that work in parallel with our existing products and infrastructure to
deliver yet more value to YesMail marketers in the near future."

The companies will also integrate AdTools' tracking technology with YesMail's eTrack software. This improved tracking will allow YesMail to capture and analyze valuable new data and seamlessly integrate it into its reports. The ability to test, measure and refine one-to-one rich email marketing communications in real time is a valuable tool for marketers and will help generate higher response
rates and ROI.
