Hi, my company recently started using AdKnowledge to serve text ads. They do a combination of e-mail ads, type-in domain traffic, and 2nd tier search engines. So far, the traffic from e-mail advertising has been performing very well. Do you know of similar services to AdKnowledge that would allow us to reach other e-mail outlets? I'm new to e-mail marketing and don't quite have an understanding for who the major players are. Has anyone ever used Datran Media? We'd be interested in using a service that isn't really focused on list management, but more on just serving ads on a platform that is already setup.

Thanks for your input!
