But stackoverflow asked users to provide an email address for the gift card as part of the survey.
Speaking from my past experience when running surveys like this at a startup, you are given the option to get a claim code to send to your customers, or to provide their emails for a one-off direct gift card message. The latter was safer because there is no handling of sensitive financial info (a live gift card code is effectively cash).
