I am using this script to pass data from a form into a URL

Problem: the email is passed encoded and a %40 is added instead of the @

• Any way to pass a non-encoded URL? I would like to pass the full email into the URL.

I need the full email because I use it then to populate a hidden field in a Typeform form.

Thanks a lot for your help :)
