I love that it is very easy to use, you can create different types of campaigns with various goals in mind for your customers/clients! The interface could be much more user friendly but they are working hard at improving this feature every month so keep up wtih them!! It's great if there aren't too many other tools out their like marketing town because its makes creating these funnels super simple (and fast!).
We have been able tto setup multiple things such as Facebook ads quickly which has allowed us get back into our groove after being laid off last year from my previous job where we were doing website design work etc..
