we want to use external content for marketing emails / newsletters. The content lives in an external CMS. We need titles, intro texts, images from this content to send emails automatically from Hubspot.
What ways exist to integrate external content into emails?
I understand that one method is that the CMS serves an RSS feed that Hubspot can read and generate email content. Is there another way? E.g. using APIs to push content from externally into Hubspot? Using HubDB?
