Your LimeSurvey version: Subscription Package "Expert" for LimeSurvey Cloud

==================Hi everyone,I’ve built an anonymous survey and would like to offer participants a €5 voucher as a thank-you. To do that, I need to collect their email addresses – but these must be stored separately so they can’t be linked back to the survey responses.What I’ve tried so far:
At the end of the survey, I added a link to a second survey where participants can leave just their email. The issue: that link can be copied and shared with friends, meaning I might end up sending vouchers to people who never actually completed the original survey.My question:
How can I set this up so that

1. emails are truly stored separately from survey data, and
2. only actual participants are able to submit their email?

Has anyone implemented something like this before or found a practical workaround?Thanks a lot! 🙏

Hi, you can put the link to the second survey in the End-URL of the first survey and set the End-URL to load automatically in the survey settings under "Presentation" Strictly speaking, it's still possible then to share the link, but I think it's rather unlikely that someone does it.
