I like how easy it is to set up, with many templates available you can create any type of email that your business needs! There are also mobile apps which makes sending emails from anywhere much easier than if using an old school desktop computer or laptop system!! It's not very well known outside US market so don't expect alot in terms customers for this software until they get big enough here - but what i do know about my list members interests me more as people who use these lists tend be quite knowledgeable anyway (in their own ways).
