I hope someone could help with this issue.
I want to use contact form 7 (or a similar plugin) to generate leads.
But... people can only submit their name, adress, etc if they have an unique key.
Is there such a plugin? Or is it possible to combine WP-invites with contact-form. I don't want people to sign up on the website, just only leave their name, address, etc with the special pre-generated invite key.
I'm using the latest version of wordpress.
