Hi @JThrun
You can set up an additional Secondary Domain in HubSpot to host your Landing Page.
Go to Settings (cog top right) > Websites (Menu bottom left) > Domains & URLs (sub menu) .
The click Connect a domian (orange button) and choose Secondary Domain, then Landing Page and follow the bouncing ball.
When you clone (or create) a Landing Page you can change the domain.
Have fun
Mike
