Bronto Email Service Pretty Good

Email marketing is something that is pretty new to me. I would say really new. It all started with that newsletter =P. Its pretty powerful stuff though. Anyway first I started doing some stuff with aweber but noticed some companies using Bronto. So I thought I would give them a shot for some things. I am pretty happy with them so far. They have a very cool API and they actually answer the phone when you call (so does aweber). I really like there deliverability. It seems to be about 2x that of aweber. They also have a lot better and easier to read graphs. But again I am a total email newb. I would love to hear what email services you use and who you would recommend.
