Is there a landing page that can only be accessible by certain audience?

To give more context, I will be running a special promotion on my shopify store specifically for my old customers (those who have already purchased). But I want the landing page only available to them and not to new customers.

Is there an app or page builder that can do that?

You can either use locksmith or Shoplock app for your requirements.
