I have a form where a lead can fill out:
- Name
- Phone
User is someone whose Email AND Phone are unique (I don’t have him/her in my Unbounce database).
Question: How to allow a user to fill out a form only once?
I don’t wanna use cookies only because if the user uses a different device to just deleted his cookies he/she can register again and that is not OK. Therefore I prefer “checking the uniques” by comparing data from Unbounce database.
