YESMAIL CLICKACTION CLIENTS EXPERIENCING BETTER THAN AVERAGE INDUSTRY RESULTS WITH EMAIL MARKETING

San Francisco, Calif. (May 5, 2003) - Yesmail ClickAction, a leading online relationship marketing company and a division of infoUSA, announced today that its retention clients are experiencing strong performance with their email programs. These clients are seeing an increase in response rates as a result of Yesmail's leading personalization technology.

During 2002, according to Opt-In News, B2C email marketing response rates declined 33 percent from 2001. Over the same period of time, Yesmail B2C retention clients experienced a 20 percent increase in response rates. In addition, Yesmails B2B retention clients experienced a 38 percent increase in response rates from 2001, while the industry's response rates dropped 12 percent. This performance is due to Yesmails strong personalization technology, which enables marketers to deliver highly relevant and personalized email messages to customers. Leveraging data such as demographic, geographic, purchase history, personal interests and message frequency preference can generate significant improvements in campaign response rates.

Solidifying the strength of Yesmail's email marketing technology, both Jupiter Research and Forrester Research recognized Yesmail for superior technology and industry-leading personalization capabilities. Yesmail was the only retention technology solution in the marketplace to be rated in the top three by both analysts in their latest email marketing focus reports.

Yesmail Clients Optimize Email Campaign Response Rates with Personalization

A leading discount online travel company, Hotwire.com, has found value in Yesmail's personalization capabilities. Prior to using Yesmail's solution, Hotwire was only able to cost effectively mail to the top 30 demographic markets. It was a manual, labor-intensive process that required 30 separate templates. Since Hotwire's email marketing campaign launch in October 2002 with Yesmail, the company is now sending to more than 200 key markets with a single template, at no incremental cost.

"Hotwire generated a return on investment within the first month of launching with Yesmail," said Ted Wham, Hotwire director, database marketing. "Yesmail has provided us with tools that have enabled us to continually send more personalized messages, utilizing far less labor by automating the process."

A leading technology and solutions provider to consumers and businesses has also turned to Yesmail to harness the power of personalization. By using Yesmail's Precision Personalization capability, this leading technology company is able to deliver content to individuals based on the product that they own, their experience level with a product and response to past campaigns. As a result, the company has increased response rates two-to-three times and increased product penetration with cross sell messages, while reducing product support costs as a result of focused content.

Jupiter Research predicts that industry response rates will continue to decline. However, Jupiter Research also states that marketers can advance response rates by increasing the relevancy of email messages. "Personalization is an invaluable tool and represents a virtually untapped opportunity for marketers seeking to break through the clutter and achieve double or even triple times the average response rates," said Yesmail's President and General Manager, Ed Henrich. "Yesmail is committed to the growth of personalization through our technology and strategic services, helping clients to realize the benefits."
