What solution should be recommended for execution efficiency?

A real estate agency wants to send out a biweekly newsletter with the list of properties for all new contacts added to a newsletter campaign in their Salesforce CRM. The journey consists of an initial message with property listings and a follow up to those who have engaged with the content.

The rules around which properties are matched to the contact depend on agent assigned as a contact owner, other agents who might have interacted with the contact, and contact’s property interest. The data model has a relationship between contact > person account > real estate agent > property objects and all of those are available in CRM as well as synchronized to Marketing Cloud.
