I like how easy it was to set up my account, all of our clients are excited about using this system! There could be more features as well but we're working with what they have now so great! It's been very helpful when creating campaigns because you don't always know which ones will work best until after sending them out (or not). The reporting aspect has also helped us improve efficiency within our organization by allowing me access information at anytime via excel or csv files sent directly from core sender through their API platform.
