I have used quite a few different services of your kind, and I think yours provides the most value for the money of any I've seen. Great tool!
We're a small company that wants to start sending a newsletter to our customers...but we can't do it without services like this.
I wanted to thank you for providing such a great service - you have saved us thousands of dollars on our advertising budget, saved hundreds of trees and over 50 percent of our leads come from contacts on our Ezine list.
