The Mack|Crounse Group, a top Democratic direct-mail firm that worked on both of President Barack Obama’s campaigns, has dissolved.

Last week, the firm’s principals, Kevin Mack and Jim Crounse, announced the formation of their own direct-mail firms in separate emails to clients and colleagues.

“We’ve come to the realization that our client bases are very different, and in today’s world of firewalls, independent expenditures, and super PAC’s [sic], this is the best step for our clients, staff and ourselves,” Crounse wrote in his email, adding that it will “take a little time to unwind” the current firm. In fact, the company’s website is still up.

“After careful consideration and some soul-searching, I have decided to set-up [sic] a new direct mail/communications firm,” Mack wrote in another email. “Moving forward, the new firm will continue to offer the same strategic, design and production excellence that we always have.”

“In fact, every member of the ‘Mack Team’ will be joining me, including my top designers and production staff,” he added.

A former Democratic Congressional Campaign Committee staffer, Mack has a client list that includes several prominent labor, women’s and environmental groups.

Crounse counted a number of top Democrats as his clients, many of whom won tough races last cycle, such as Indiana Sen. Joe Donnelly, California Rep. Scott Peters and Arizona Rep. Kyrsten Sinema. He also worked on direct mail for Obama’s campaigns in 2008 and 2012, according to his biography.
