Is it ok to email buyers of my Android app?

[jere_jones]

I'm a new Android developer and have released 2 different apps. RealMirror is free and I released it about 6 weeks ago. It has done, in my opinion, well with over 10,000 downloads.

Monday, I published my first paid app, mySoundboard. With no downloads at all for the first 48 hours, I was very disappointed.

Last night I had 2 downloads. I am very happy and more than just a little grateful. I don't have their real emails, but I do have a Google Checkout anonymous email address that I can use. Is it ok to email the buyers and say thank you or would that be too creepy?

Its a noble sentiment but i think it does risk creeping out the people the who did download it which would rather defeat the object of the exercise.

Why not include a "Thanks to everyone who downloaded v1.0" message in the About screen in the next update of the app or the app info screen on the Market?

Definitely toeing the "Permission based marketing" line there, but sometimes you gotta be a little scrappy :)

I'm sorry, but I don't understand. :-) Could you elaborate?
