Need A Bulk Mail Company – Who Would You Recommend?

I need a managed bulk mailer, someone who is not just giving servers but knows what they are doing. I don't have the time or energy to learn how to bulk mail and I will pay for it to be managed.

Has anyone tried this with any success? Not that you made money but you got clicks to an offer? I can monetize just fine, I just need help with mailing to offers.
