Before using your service I was with. For the first time using your service I missed a feature that has that you don't. They have a star rating system for every subscriber based on the subscriber activity reading emails, clicks links etc. I wanted to clean out my list ideally removing inactive clients. I also wanted to send a special promotion to all of the 5 star clients because they are the most actively and likely to make an extra purchase. Is this something you could implement in the future? Thank you for your consideration, Josh
