Hear what some of our happy customers think...


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.

Gary Wand   |   Pygott and Crone

I can thoroughly recommend SMS. They have always provided a top service with fast support when needed.

Recently they have overseen a migration to Exchange 2016 which completed very smoothly, probably down to their extensive planning and preparation.

Simon Gipson   |   Spire Payments Limited

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.
