I think what you described is related to the fact that I can import people from a specific marketing campaign and then enrich them based on website, linkedin profile page etc. I get that. However, is there a way to enrich those people based on information from the CRM?
Example: I get person as a lead in Salesforce which is from company ABC Inc. However, he is not linked to the account in our CRM and I should check further if that company has already a product of ours.
