Hello @sjcarter,

Great observation!

Unlike a signup form which can accept multiple inputs before having it submitted, the strategy highlighted in the Configure Your Email Template to Collect User Ratings section of the Include Ratings Links or NPS Surveys in an Email Help Center article is leveraging the update profile property link function. 

Technically speaking you can have multiple sets of questions to collect feedback, however in order to answer all the multiple questions, your recipients would be required to navigate back to their email and click on one of their choice each time. This is because each button click would redirect users to a specific link/URL. Although it is feasible, it doesn’t offer the greatest user experience. 

To collect a variety of answers or feedback from users, you’ll want to use a third-party tool such as Typeform which would allow a similar implementation or to redirect your recipients to a signup form on your site. 

I hope this helps!
