So, I need to send a url link through email to my patients, so they can fill a survey that will be saved on my patient record.

My patients  have no user (user licenses $$$) created in Salesforce, so I cannot use the Community approach (as far as I know Communities are based on Users).

Can this be done under these circunstances? Any ideas?
