You may want to preview your Easypop campaign on a live store while keeping it hidden from customers. This is useful when the campaign editor preview just doesn't cut it.
Open the campaign editor for the campaign you'd like to preview
Navigate to the Settings tab
Add a URL condition for contains "test"
Open your Shopify store and navigate to any page then add ?test
to the end of your URL
This should look something like https://building-easypop.myshopify.com/?test
