Our company Youtily would like the ability to write cookie parameters to hidden fields in the same way that we can currently write URL parameters to a hidden field.
We have a landing page where in addition to the form fields we pass google UTM parameters into hidden fields. This is an unbounce page integrated with a hubspot form. We are going to be creating a LP with just a button that redirects to our product page signup funnel. We would like to continue passing the UTM parameters into hidden fields upon button submit, but there will be no email to associate these fields to. the alternative we were considering was to write those UTM’s to cookies, and then capture them later when the user eventually gives us email in the product page signup funnel. let me know if any of that does not make sense.
