The best part about this software has to be how easy it makes creating personalized emails for my clients! I can literally create all kinds of different campaigns within minutes without having any prior experience with marketing or email creation!! Creating customized content takes no time at al either which really helps speed up our workflow as well. There's not much i dislike yet but if there were anything more efficient than being able to use templates would definitely make improvements here too :). We're using Pareto principle when we send out newsletters so every piece (or person) contributes towards getting us closer toward reaching specific goals such as sales leads etc..
