Hi there -- Yes, you can! You'll just need to host that survey publically (rather than visiting it from a link sent through one of your mailings) in order to fill it out multiple times. I've explained that in more detail here!
Can Emma allow a survey embedded into an email to be taken more than one time? We use surveys all the time as RSVPs, and our users may click the link but not complete the survey/ RSVP at that time. When that same user returns, they are unable to fill out the survey. Or is that a user/ set up error on our part?
