Updated, I've tried it again as it was the nicest interface of all the CRMs that I've tried. The DNS setting were eventually sorted out but it wasn't particularly easy. I'm going to try it for a month or two to see if it justifies the cost. I really wanted to like this app. Lots of promise, looks great and has lots of potential. The support is excellent too. The big problem for me is that it is just too difficult to set up - even support couldn't solve our issues. For a premium priced app, it should be seamless - but it just isn't.
