I can't tell you how wonderful you are. I was a COBOL programmer and to find this kind of responsiveness in tech support is amazing.
Thanks for your wonderful service! I have tried other newletter service providers, and yours is by far the best, no-nonsense tool around!!
...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.
