Pros: It does have the nice functionality of being an all in one able product that syncs up with other blackbaud products.
Cons: it is clunky, takes a lot of learning. It is nowhere near as user friendly as many other less expensive products. the set up and learning curve is high level. if you're not fluent in html, don't even TRY to get started with the messaging capacities!
Overall: none, I would LOVE to go back to our previous mass communication system!
