The most helpful thing for me is that I can easily create different types of newsletters, like one-time or regular emails sent out regularly without any problems at all! It also has an easy interface which makes it very user friendly in terms what you need when using this software - nothing really bad about mailcraft either as far i have experienced sofar but if they could improve some things then maybe make them better? Nothing specifically since its pretty good otherwise just keep up their great work :) Great tool especially considering how simple yet effective your email marketing campaigns are going through by having these ebooks available online!
