Their support is excellent. They might not get to you right away or no the answer fast, but they stay with you through live chat support and walk you through what you are doing to make sure your issue is resolved.
We have two client websites that we have installed the JNews extension on> Very user friendly to train your client on how to do it. Great user interface. Alot of things are self explanatory, but if you get confused the live support will walk you through it step by step.
One of the things I like the most is the template is easy top make changes and adjust colors and codes to make your newsletter look the way you want it.
Easy to install and powerful to use. Good job Joobi.
