Coremetrics Announces Launch of LIVEmail Program Featuring Four Leading Email Marketing Partners

@Once, CheetahMail, Digital Impact and Responsys Leverage Coremetrics LIVE Profile Data to Provide Highly Targeted Behavior-Based Retention Marketing Campaigns

Burlingame, CA – September 2, 2003 – CoremetricsÔ, the leading provider of online marketing analytics solutions, today announced the launch of the LIVEmail Partner Program to offer an end-to-end solution for delivering relevant and highly-targeted email marketing based on browsing behavior. Under the terms of the agreement, partners will integrate Coremetrics` LIVE (Lifetime Individual Visitor Experience) Profiles into their web-based interfaces to enable the seamless execution of highly targeted, measurable email campaigns that influence prospect behavior and deepen customer relationships. @Once, CheetahMail, Digital Impact, and Responsys have all joined the Coremetrics LIVEmail Partner Program.

Coremetrics was recently named the sole market leader in an industry report on Web analytics conducted by Forrester Research, and is the only company to capture and store all customer and visitor clickstream activity to build LIVE (Lifetime Individual Visitor Experience) Profiles that serve as the foundation for all successful marketing initiatives. The seamless integration of LIVE Profiles with email marketing applications enables retention marketing managers to create relevant behavioral segments for targeting, and immediately execute email campaigns with the optimal offers to capitalize on observed behavior.

“LIVEmail is only one example of how LIVE Profile data can be applied – in this case outside of our Marketforce platform and inside partner applications. We are only starting to unlock the full value of LIVE Profiles, which have proven to be the most accurate, comprehensive form of data available about online behavior," said Scott Kauffman, chairman of Coremetrics. "We are excited to welcome these four companies to our LIVEmail Partner Program, and we fully expect that many more sophisticated uses for LIVE Profiles will follow as partners and clients find new and exciting ways to unleash their potential."

A simple and automated means of achieving perfect targeting for email campaigns, LIVEMail delivers to clients a seamless integration with their current email vendor featuring effortless data transfer and automated campaign reporting in the Coremetrics Marketing Management Center (MMC). LIVEmail enables marketers to deliver highly targeted email campaigns based upon customer browsing, abandonment, conversion and purchase RFM variables directly from their email marketing interface. In addition, desirable but previously difficult campaign combinations are now easily automated. Marketers can target product abandoners, high service-level customers, accessory upsell candidates, application non-completers, high value customers and inactive visitors with specific messages and offers to yield higher profits and increased customer lifetime value. LIVEmail enhances the bottom line for eBusinesses by allowing them to rely on Coremetrics and their email marketing vendor’s expertise in effective campaign creation and marketing to rapidly achieve substantial, verifiable marketing return on investment and real profitability growth. Clients can access the full power of the integrated platform with zero technical integration work.

"For PETCO, LIVEmail represents an exciting new way of deploying LIVE Profiles to increase customer satisfaction and lifetime value," said Heather Blank, director of eCommerce and business development at PETCO. "We evaluate every marketing program based upon conversion, revenue, and margin contributions. Like other LIVEmail customers who have experienced success with the program, we expect LIVEmail to help boost our performance across all of these key performance indicators. We plan to take full advantage of the integrated LIVEmail solution to drive better returns on our retention marketing, while providing highly relevant offers and creative to our customers."

"We are thrilled with what the LIVEmail Partner Program can do for our joint clients and their online customers," said John Harrison, vice president of product strategy and production of @Once, a full-service eMessaging firm. "Our collective integration marries the rich and deep consumer site information fed by Coremetrics` LIVEmail with @Once`s unique ability to turn complex data into actionable and manageable highly personalized email campaigns, all to drive ROI seamlessly for our clients. The LIVEmail solution closes any remaining information gap in @Once`s ability to design, develop, and execute the most effective trigger-based campaigns."

The insight of Coremetrics Web analytics combined with CheetahMail`s best of breed email marketing technologies allows CheetahMail clients to execute more relevant and timely, behavior and response driven email campaigns." said Irene Pedraza, CEO of CheetahMail

Together we will offer our customers an even more robust solution."
