Unlike Any Other Service Provider
We take on the burdensome IT functions of in-house email hosting and eliminate the need to maintain and administer an internal email infrastructure, freeing up valuable IT resources and capital expenditures. Beyond the increased efficiency, USA.NET provides high-touch customer support — at every level, a multi-million dollar infrastructure, and a broad range of email services to meet the expanding needs of our clients.

Before we switched to USA.net’s hosted exchange service, we were having problems with our previous provider. There problems included service outages were up to 4 days long or more. With USA.net we have never had this problem (we have been using the USA.net service for about 6 months now) and migrating to USA.net was straightforward. They provided us with a very clearly explained process along with all the steps. Their customer support department was always avaialbe and quided us through the entire process. I would recommend USA.net to others.
I just wanted to let you know that I am very happy with the service you offer. I had an exchange server in house, shut it down, and went with your service. Sign-up was easy. After sign-up, I received my welcome email and the instructions in the email were very clear. The support provides lots of help. After having complete control of our in-house server, I thought that it would be very limiting to the admin, but there again your company shines with lots of options for the admin. I would recommend USA.net to anyone looking for a hosting company.
