I'm sending email to a subset of Synchronized Data Extension and returning the tracking to Sales Cloud. Apart from data stream how can I do this. Can data filters be used for sending tracking data?
Tracking data is pushed back to Salesforce automatically via the Connector when preforming a Salesforce Send (as apposed to a User-initiated Send) The data is pushed to the IndividualEmailResult custom object.
Salesforce Sends can only deploy to Reports or Campaigns in Salesforce or what's called a Salesforce Data Extension.
