I like that it's easy for me as an administrator (or even just someone who is new) because there are many features available at my fingertips! It also lets you preview images/emails from any program or website with ease which makes life easier when trying something out before sending off! The only thing i dislike about this software so far has been having too much information displayed sometimes when using certain programs such as Outlook 2016 - however luckily these issues seem minor compared to everything else which really does make up what can be considered 'the good' side :) Great tool overall!! You will need some knowledge regarding how emails work if not familiar first time around; otherwise things should run smoothly after learning where each button goes & knowing exactly why they're used etc..
