Need help writing a professional email about placing users in a Pilot group to monitor a product I am deploying

I need help with writing an email about adding a few users to a pilot group before I deploy a product (web filter) in our environment. I am not good at writing up a professional email, and need a template. Please make this short and simple. Just help me write an email, detailing the attached. Make it as professional as possible. Sorry, I'm IT, but suck when it comes to writing.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Attention users:

We will be adding a few users before the final deployment of our product XXX in order to establish a small pilot group for some final testing and feedback.  Please relay any concerns or product issues to or call our technical staff at xxx-xxx-xxxx.

Thank you for your help and patience with our new web filter.
