Browsing Hubspot's blog, I came across a CTA that had an integrated form and I would very much like Hubspot to make such an asset available in the marketing tools, considering it ptimizes conversions.
When I asked Hubspot support what feature the company itself was using, they told me it wasn't a native tool. So I think it would be great to make it native as Hubspot itself sees the need to use it in their blog content.
