The platform is very easy, intuitive system that allows me manage my campaigns with ease. Nothing really! I would like some more support for beginners in terms of training resources available online or offline (books/videos). But it's great so far as all what we need was there when starting out from scratch. We started using this tool almost 4 months ago now. It has been an excellent experience thus far - great customer service; fast turnaround time between campaigns launched & results achieved; good reports / insights generated by our account manager who manages the team behind the scenes making sure each campaign runs smoothly.
