How can my leads just click on a link in an email and be registered for a pdf without needing to fill in the form?

If they are already a lead, just simply add a link to the PDF in the email (you can host the pdf in Dropbox, google drive, or in Kartra Memberships, Files).

But if you do send them a link to a squeeze page with a form, they won’t have to fill it out they would just need to click the button to confirm as their info would be pre-filled.
