How to Embed Styled Google Forms in HubSpot CMS
HubSpot CMS is a powerhouse for marketing teams and B2B organizations. However, utilizing HubSpot's native form builder often requires costly Marketing Hub tier upgrades ($500+/month) to unlock custom styling, remove HubSpot branding, or route data to non-HubSpot systems.
Default Google Forms iframes on HubSpot look jarring, break mobile responsiveness, and display generic Google styling that undermines professional B2B credibility.
CustomGForm allows B2B marketing teams to embed pixel-perfect, branded Google Forms on any HubSpot landing page, blog post, or knowledge base article — piping all submissions directly into Google Sheets and triggering instant webhooks.
