Best Plug-In for EMail and Automated Notices

I tried 2 other plug-ins, but couldn’t get them to work for me. With Mail Poet everything worked straight off and I really like their easy-to-use interface. Plus, when I had a question I sent an e-mail and they responded, telling me the answer to my question. That was really helpful and now I’m sending my newsletters regularly. Thanks so much for this great tool!
