This is too custom needs and possible only via custom paid work. In theme, it's possible to trigger only login popup, so non logged users will see popup for registration. And you can get their emails from user database

Hello,

Can you please advice on the ticket? Thank you.

Hello,

I am looking to collect customers email and name information before they once they click on external link to visit an affiliate website. I was hoping to use http://demo.wponlinesupport.com/popup-anything-on-click-demo/ plugin on any other similar plugins, but all of them use shortcodes. There is no way to add a shortcode to the field of the external link url. Is there a way of making this work somehow? So customer clicks on buttom "Visit Website", a pop us on my website opens up with name and email fields, customer enters his information and clicks on "Proceed to site" inside the pop up. Please let me know. Thank you.
