An app I have in the App Store has a “Support” button in its in-app settings; I’ve received a lot of blank emails from users (I think they hit Cancel, then “Save Draft,” then send the email later), but I’ve received a fair share of really useful emails from people who have questions and/or comments about the app. I’d definitely ignore the blank ones and keep the button in your app.
