Unica's Affinium[R] provides Las Vegas hotel with top-of-the-line, automated workflow management

WALTHAM, Mass. -- Unica Corporation (Nasdaq: UNCA), a global provider of enterprise marketing management (EMM) solutions, today announced that Ameristar Casinos, Inc., a leading Las Vegas-based gaming and entertainment company, has implemented Unica's Affinium[R] for its marketing resource management (MRM) solution.

With Affinium, Ameristar is able to create a more efficient and automated workflow management system across its key locations. The company will be using Affinium for production management, quality control and approval cycles.

"Our workflow is complex, so when we first started shopping for a marketing resource management solution, we looked at systems that had lots of bells and whistles," said Jerome Mandel, vice president of database marketing at Ameristar. "We learned that we didn't need a complex system for our solution. What we needed was a solution with a flexible, open architecture that could support our fast-paced marketing environment. We brought in Unica's Affinium software because it could be readily tailored to how we work at Ameristar. Our Unica system is incredibly streamlined and user-friendly, which lets us get our job done more efficiently and effectively."

Ameristar needed a solution that could be tailored to manage its complex workflow quickly and intuitively. Having successfully used Unica's Affinium for more than three years to help with its campaign management needs, the company turned to Unica once again for its MRM solution. The open architecture and adaptability of Unica's Affinium software was an ideal fit for Ameristar's overall marketing goals of collaboration and process efficiency.

"Ameristar was looking for a flexible solution that could meet the demands of its complex workflow between multiple locations and vendors and could easily handle many people interfacing with the solution," said Yuchun Lee, CEO of Unica Corporation. "We are excited to work with Ameristar to help the company meet its goals for enhanced marketing success and process efficiency."

Unica's MRM solution at Ameristar was implemented by Equifax Inc. (NYSE:EFX), a Unica partner and a global leader in information solutions. A long-standing customer of Equifax, Ameristar relies on Equifax's database solution to maximize its marketing efforts and manage and grow its customer base. Through its relationship with Equifax, Ameristar selected Unica's MRM solution.
