I like how easy this tool is for marketers, it's super intuitive and allows you to track your emails really well. There are some things that could be improved though. For example, sometimes there would be a glitch where certain data would not show up in analytics even after refreshing or re-opening their account. It also takes forever to load when first launching the dashboard.
Also, they have been pretty slow at responding to inquiries as well. We've used them primarily with our marketing team
