A client has a single SFMC (email only) BU configured & working. All subscriber data resides in the Sales CRM cloud. They want 10+ additional BUs setup and configured to deploy emails for separate divisions of the same organization.
When creating a new hierarchy BUs in SFMC:
- Does each BU require a unique cloud connector to sales cloud, or does just the root BU need the connector, to feed a Shared Data Extension?
- Does the root Sender Auth Package (SAP) & sender profiles cascade into the other BUs or need to be reconfigured, even when using the same sender domain?
- Whats the best method to control subscriber opt-in status (unsubscribes) across multiple BUs?
Basically, with a root BU already running, are the additional BU standup & configurations the same level of effort, or very easy because it uses the root BU previously configured components?
