Marketing Cloud Engagement Tenant Types
Learn about the different types of tenants in Marketing Cloud Engagement.
The definition of a tenant depends on the type of Marketing Cloud Engagement account you use:
- Enterprise 2.0 accounts—The top-level account and all associated business units under it.
- Enterprise accounts—The top-level account and all associated On-Your-Behalf or Lock & Publish business units.
- Core accounts—The single account.
- Agency accounts—Each top-level account and each associated client account is a separate tenant.
Each Core account, top-level Enterprise or Enterprise 2.0 accounts, Agency account, and any associated child accounts have a member ID (MID) value that identifies the entity. Tenants can include a single or multiple MIDs, depending on the account type.
