An inexpensive, simple email software without the bloat found in many of the competitors. If you just want to create emails and send them to your lists, this is a far cheaper alternative than what you'd pay for similar software. Have sent a few emails out to multiple lists and have not had any issues with delivery.

Clean, intuitive interface. Can have the same contact on multiple lists, without being charged separately for each contact.

It is comprehensive and very easy to use. It has everything you need to get up and running at a fraction of the cost of other alternatives, and they are improving all the time.
