I'd like to offer free Jumpshot scans

Hello,

About a year ago there was a post where Logan told us about Jumpshot an app where you use Linux to fix Windows. Well, I decided to become a backer and now I can "gift" a free scan to as many people as I like, but only one per person.

I would like to offer this to members of Tek Syndicate; however I need to have a list of email addresses to send the "gift scan" to. I promise I won't go and sell the list for money. To do this, I'd like some suggestions on how to collect the list of addresses in a secure way that assures people their information is safe.

If I could get some help from the Tek Syndicate team, or community that would be awesome.
