InfoUSA has acquired both e-mail marketing companies since December.
The combined company, tentatively called Yesmail ClickAction, will be headed by Yesmail's Ed Henrich, who becomes president-general manager of the entity. George Grant, president-general manager of ClickAction, becomes exec VP-business development.
"We decided we had two smaller businesses that could benefit from being one larger business," Henrich said. Yesmail's Chicago-based list operations will report to Ed Mallin, president of infoUSA's Walter Karl Inc.
