"What I'm trying to say is that the best way to get feedback from users without pissing them off is simply to do something that they really really like, and that they want to you to keep improving." To me, the type of email you sent is the most useless email I could receive. It contains: nothing I can help you with; nothing I can improve; nothing that you had a problem with... it's empty kudos. Secondly, it's very difficult to create something people "really really like" without asking them why they don't like what you are currently providing. And since people don't care about products they don't like, they will rarely tell you what's wrong if you don't ask... they'll just leave, and you'll never know why. To improve your email, instead of simply telling them that their service was great.. tell them what your favorite feature was or what was the most helpful about their service. At least that will give them some idea of why you liked it, and it might give them some idea how they can improve other parts of their service.
