When an owner buys a product and opts in to communication, we send them an email via CRM asking them to take a survey. I cannot pass through the email from CRM, and I don't want to ask the respondent again for their email address. I want to add an incentive via a coupon code for another product. I have to pre-generate the list of coupon codes. I have 50K codes, and I want to select one to pipe in on the end page after a survey is completed. Then I want to never use that coupon again. What is the best way to do this?

Can you pass the code via a query string in the link to the survey?
