The dashboard has a lot of features, it's easy to use and really great at reporting. I've been using this service for about 3 months now and had no problems. If i could think of anything that i would like to change it would be the design. It can be sometimes confusing because you have to click several times in order to access some of the graphs. This shouldnt be a problem since the tool is very good otherwise. It helps me to understand how people are receiving my emails and also what links they're clicking the most. It helps me to improve my campaigns and reach more of my target audience.
