One thing OJ and SI pointed out in their feedback on the survey was that we do not have the right to collect the names of the respondents since we did not include such a request in the ethical application. Rather, in order to be of the safe side, OJ then suggested to ask the respondents to re-enter their email addresses as a security measure since they could easily misspell it once but not twice.

I asked our REDCap expert on Lund University, AJ, how to do that and she suggested me to have a look at this tutorial.
