The user interface of Smarketing is very simple to use, they have a very strong support team which also helps you when troubleshooting any problems you may be having. Sometimes it can be difficult to get a hold of someone through their support line, but that's only because I'm not an expert in using this platform. Definitely give it a try if you are looking for a solution for your email marketing needs. It has helped us track our open rates and see which emails were getting opened more than others as well as those who weren't opening at all.
