Don’t Just Take Our Word…

Here’s what our customers have to say about SMS
pygott-and-crone

SMS gave us the ability to run our email system exactly as we did when when we hosted our own Exchange server but with the added benefit of removing the single point of failure which our own system had.

The support is second to none. SMS provide a very good package and if we were to setup again from scratch then SMS would be at the top of the list.
