Sprocket Rocket modules are currently built specifically for HubSpot website and landing pages and are not available for use in emails, newsletters, or case studies.
HubSpot uses separate editors and module systems for website and landing pages, emails, and case studies. Because of this, Sprocket Rocket modules can only be used on website pages. For emails and newsletters, you will need to use HubSpot’s default email templates and modules or custom-built email templates. Case studies also rely on their own template structure within HubSpot.
