I love the detailed campaign stats and the control panel is relatively easy to navigate.
Your service is absolutely hands down the most cost effective marketing tool I have ever seen - and your service just gets better and better!
I'm pretty stunned at how well your service works -- it's easily one of the most intuitive applications I've ever used. Most important, it seems to work! It took me only about an hour to get a newsletter through the test point. My highest compliments.
