I like how easy it was to set up my account with them! They were able to walk me through everything step by step so that when we got into our first meeting for implementation they knew exactly what needed done in order get us going as fast or slow as required (and did!).
There isn't much not liked about this product - however if you're looking at getting an email solution then there are plenty other options out their which may be better suited depending upon your needs/requirements etc.. We've been using these solutions since April 2016 but have had no problems yet from any issues within the system itself nor do i foresee anything coming along down the line causing trouble either!!
