Reply To: Popup element

Hello,

You can only use the WPBakery Elements inside the popup or add newsletter shortcodes with social icons. Then Edit the Popup settings >> General Tab >> Change the Width of the Popup. Please see the screenshot: http://prnt.sc/sqlpen

If still you are not able to do that then please send me the WP admin login details of your site and page URL where you have added the HTML block inside the Popup or Pop Up button so I will check and do it for you.

Best Regards.
