Hello @EJ_Byun,
I would suggest you use a third party to take care of the content you want to provide. For example, on MailChimp You can set up specific content to be delivered to people that signed up for your newsletter, but I don’t think you can do that directly on webflow. It is fairly easy to set up the mailchimp integration on webflow. You can also set up dynamic content with the mailchimp integration, as far as I know. Do you already have to website set up? your share link is not working.
