You can't make them signup and send them the codes without seeing the email. This is not implemented in Limesurvey.

I honestly see no problem if you see their email address. This is done in market research all the time. If you disconnect their personal data from their responses, you have no way to connect them to their results and that is what counts.

Complete technical anonymity is nice, but comes with a lot of disadvantages and makes some things impossible or very dangerous (like in your case).

What you could do is to let them participate in the survey and then via the end url feature you redirect them to another survey. If you don't pass on any code, there is no way for you to connect their responses to the second survey, where you ask them for their contact details to send them the code. It doesn't protect you completely from people answering more than once to get an additional voucher, but at least it makes it harder. If you then also use tokens with your link, they would have to take more than one paper with them to be able to respond more than once, or go back and get a others. Overall, the recruitment approach together with incentives is always going to be somehow tricky.

For a scientific project I honestly don't see any need to provide incentives at all. People usually participate because they are interested in the study to be a success or because they want to help out the scientist. If your survey isn't extremely long, of course.

Thanks, holch :)

That seems like the most viable solution.

Redirect to a survey with 1 question that says "please provide an email address to which we can send your $10" and then from that, I can compile the email addresses and just send an email to each like:

"Dear participant,

blah blah blah, here's a code for $10 to amazon.

111 222 333 444

Thanks for your participation,

Researcher"

And one tip from market research practice: I have worked with raffles of 50 Euro vouchers (20 per 1000 participants) for years for many, many surveys. We purchased many vouchers each year and you'll be surprised how many people will NOT redeem their vouchers. At least I was.

I wouldn't want to give presents to Amazon, they have enough money. So what we did was taking the expiration date of the vouchers purchased and take off one month and communicate this expiration date to the respondents. I think the expiration date is somewhere around 1 year.

So you give them 11 months. Then when the date is over that you gave to the respondents, you check if the vouchers have been redeemed. If not, you redeem them. We increased the library in the company quite a bit and could also buy quite a few appliances with it as well.
No one will come after eleven months and say, ohhh, wait, my voucher! And if they do you can just pay them their 10 dollars. In various years we had no case and actually the respondents can't even complain, because the voucher for them has actually expired. I just wouldn't want give money to Amazon for nothing. Jeff doesn't need more money. He is fine, even after the divorce. ;-)

Without passing any additional code, you risk that the URL of the second survey is directly accessed and distributed via social media. That is the worst case, cause you end up with a lot of responses and don't know which is valid. Even if you have all email addresses of potential valid respondents, you cannot expect that people use the same emailadresss for the vouchers.

LimeSurvey is missing a questiontype for collecting contact data separately.
E.g. like this www.soscisurvey.de/help/doku.php/en:create:questions:contact

As I said, the combination is not perfect and someone savvy will find a way to get to the vouchers. The solution is a lot saver, but yes, it would be best to have a question within the survey and then you just separate the two data sets. Unfortunately LS does not have a feature to keep the personal data out of the results table, but then anonymity is generally not only a technical thing, but rather a process. For years market research has run anonymous surveys, that depended purely on how the data were treated, because if you wanted to, you COULD connect personal data with responses. A responsible company wouldn't do it. But you could.
