I liked that there was always something new coming out from flow box! They were constantly adding features or updating old ones so they could keep up with demand as well have room if things changed at any time down stream (which of course happens).
It would be great it you had an account manager who knew what we needed but not everyone does which made getting support difficult sometimes because some people didn't understand certain terms like'retargeting' when asked by another person about specific options/features - however this isn’t really anyone else fault other than lack education within those companies own employees themselves rather then having someone working solely dedicated towards your product specifically etc.. But once again thats just my experience only!! We used several aspects such as targeting potential clients through retargetting them after purchasing items to also building relationships using Facebook pages & groups along side creating blog posts where users comment positively.
