Support for Smart content on external websites (like Wordpress) just like smart CTA's w/ embed code

This is sorely needed or we may need to move to a CRM that has better integration with our primary domain. With the latest AI analysis of how Google ranks search returns based in large part on user experience, subdomain/offsite landing pages are no longer a good idea. So we need to be able to define custom content on our website when we get a visitor who is in a sequence.

We tried the API to at least know if a website visitor is a Hubspot contact, and it worked, but the endpoint closed for us after the “error rate” (not-a-contact) exceeded 5%. Insane.

Hubspot -- we need this.
