For event invitations and non-responder emails, the link coded for the "Register Now!" default text will always link directly to the registration form itself. The "Get More Information" default text will link to the landing page directly.
Only the event's default share URL will change how it directs, based on whether the event's landing page is active or not. If you want, you can edit the "Register Now!" link of your invites to instead be the event's regular share URL.
For more info on these processes and how they function with each other, please see this article.
