Your service is absolutely hands down the most cost effective marketing tool I have ever seen - and your service just gets better and better!
...having found your service by chance, we've been completely happy and pretty surprised actually. You offer a lot of features, with a very reasonable & logical rate system. ...How much your service will help is possibly beyond your understanding, but I'm sure you've heard that from other people using your service.
Great service, I recommend Ezine Director as much as possible.
