I was initially attracted to their products because of the free trial period, but I'm disappointed to say the trial version does not work as advertised. For starters, the trial version is crippled. When I attempt to upload an Excel file, the application freezes. When I upload a PDF document, it opens the document but won't let me print it. When I attempt to create a new campaign from scratch, it keeps freezing. I attempted to call customer support, but the first call was disconnected, and subsequent calls were met with dead air.
