Your site and program are pretty slick.
I have been using Microsoft List Builder previously. You product is excellent. I will be cancelling my List Builder at the end of this month!
For your information, I have switched from Microsoft BCentral to your company because of your prices are almost 2/3rds cheaper that them. Keep your prices low and I'll be a customer for a long time. The fact that mailings can be scheduled ahead of time is also great.
