Carleton and Prime Response Partner to Provide Rapid Customer Data Management Capabilities for Effective CRM.

MINNETONKA, Minn.--(BUSINESS WIRE)--Sept. 28, 1999--

Carleton Corp. (Nasdaq:CARL), a leading provider of customer data management solutions, and Prime Response, a leading visionary in the marketing automation arena, announced today a partnership to deliver a complete closed-loop marketing solution that provides powerful customer data management capabilities coupled with the leading marketing automation application. This partnership combines Pure.View's(TM) powerful functionality to rapidly create a complete view of customers through an integrated customer data management solution with [e-mail]'s(TM) robust ability to analyze, plan, execute and track multi-channel marketing, enabling organizations to quickly implement enterprise-wide customer relationship management (CRM) initiatives for a faster return on investment. The bundling of [e-mail] with Carleton's Pure.View enables organizations to build customer-centric data marts and data warehouses more rapidly, easily and cost-effectively.

"Prime Response is an innovative leader in marketing automation solutions, and they understand the importance of customer-centric data management in implementing company-wide marketing or CRM strategies," said Robert D. Gordon, Carleton's president and CEO. "Customer relationship management is the reason many of our clients are building customer-centric data warehouses. Pure.View solves the key customer data challenges and creates a single integrated view of customers. The combined capabilities of Pure.View and [e-mail] make the goal of closed-loop relationship marketing a reality."

"At Prime Response, we believe that a robust customer data management strategy is critical to delivering the greatest value and fastest time to market from our world class campaign management solutions. Our alliance with Carleton enhances the exceptional value we bring to our customers," said Peter J. Boni, president and CEO of Prime Response. "With Pure.View's data cleansing, transformation and integration capabilities, our customers now have the additional capability to rapidly build and maintain a single, accurate profile of their customers across an entire enterprise."

Historically, marketing automation solutions were implemented with the assumption that a customer data warehouse or campaign data mart existed. In many cases, enterprises are still building their customer data warehouse or data mart, creating barriers to successfully integrating marketing campaigns across an entire enterprise. Carleton's Pure.View rapidly creates a customer data warehouse or data mart to integrate data from diverse sources and combine it with external data sources, such as demographic information or business profiles. This capability enables companies to integrate the campaign management process enterprise-wide to more effectively measure campaign effectiveness, acquire response data and analyze interest and preferences from web channels.

Carleton's Pure.View is the only fully integrated customer data management solution on the market today with the full range of powerful customer data transformation, integration, and cleansing capabilities. Prime Response's [e-mail] is the first Web-based, multi-channel marketing automation software that integrates Internet and traditional marketing channels, including the Web, e-mail, direct mail, call centers, direct sales systems, points-of-sale and mass advertising.
