Where: Experian CheetahMail, New York
Why: Seeley, like all good e-mail marketers, focuses on relevance. However he goes one step further when he tells clients that e-mail should be meaningful as well. This year, the company introduced a prioritization tool that allows marketers to efficiently prioritize messages so recipients aren't inundated with the wrong e-mail at the wrong time. Seeley, who helped lead the company into nine international markets, has also been instrumental in creating user communities within his own client base and creating client advocacy programs.
