What I like here is the clear system.
Template creator is great and smart.
Translation system amazing!!
The statistic great. even in the free version it's better then other commercial newsletter system.
I have some Acajoom licenses and I have to tell you AcyMailing will be my newsletter option for my clients. I read some reviews here about support and it's look like it's ok. The support in Acajoom (commercial ver) is really poor.
