iphone app userid

Question

I have an app where we want users to be able to send us email/info. This would be a standard template which will open up on a button click within the app.

I am struggling at the moment to find a legit way to do it. The problem is there are 2 things I need.

1) A way to let users send email to me 2) A way of knowing the person sending me mail is actually someone who has downloaded my app.

Does anyone know if there is a way to do this? Does apple give us information/user id's or email id's of poeple who have downloaded the app?

Many thanks in advance for any help with this..

Here's a good example on how to send email. As for identifying if they send it from your app, you might have to create some login feature on your own. I haven't heard of Apple providing IDs of users who have bought your app.
