emailing current app users

I have an app on the app store that is a one time purchase. I did not ask for any emails with the order. Is there any way I can contact them requesting there ideas about my app? I do not want to add a new version.
If you mean link purchases to users and their email addresses - no, the store does not provide the dev with that level of customer info.

Best to use your website, and any social media exposure you may have developed along the way.
