The best thing about this software is that it gives you all the features at one place. It is very easy to use and has a variety of tools for different needs. I dislike the fact that it takes sometime to load. So, if your website loads slowly, then there's nothing wrong with it. But if you are having any issues related to loading speed, then there might be something wrong with your hosting server or some other issue. This software helps me in tracking the open rate of my emails and also helps me in analyzing my bounce rate.
