Alex wants to know if there's a way to make some content within an email module visible only when editing the email in the HubSpot editor, and hidden when the email is actually sent.

James provides a HubL snippet using `{% unless contact.email and contact.email != 'CONTACT.EMAIL' %}`. This condition checks if the `contact.email` personalization token is absent or has its default placeholder value, which is typically true in the editor context but false in a live send. Content placed inside this block will only render in the editor.
