The best thing about this software has been its simplicity for customers who are new into online business or have no knowledge at all how it works! It's really simple which makes them understand very quickly what they need from us (the service provider). I love that we can send out newsletters without having too much hassle when using their services because everything was so well organized by themselves before contacting our team here at MobiMailers Team. They were able to help me find my own way around since i'm not familiarized yet but still made sure that every step along the way will be explained clearly enough until reaching where ever needed. Great experience overall. Nothing majorly bad either except maybe some minor issues like slow loading time after receiving emails/newsletters etc., however those problems weren't serious nor did affect any other part negatively.
