I like that it is so easy! It doesn't take much time at all once you have everything set up correctly-which isn´t hard either if your system works well in general (the site will walk through this step bystep).
You can use as many different services/products from other companies within one profile or even change providers without creating lots of problems with data transfer etc.-you just need an export file first before importing into enviroware afterwards which takes only seconds after clicking "import". The product itself has not changed over recent years but they did add more options when editing templates - some are quite complicated though i'm sure there's no problem using older versions anyway since most things work exactly how we want now anyways;-) We also used old version back than until recently where our account was closed down because my predecessor had left us too soon while still being paid via invoice instead of having his admin access taken away.
