One bill, isolated tenants
Give each client or product its own account. Own domains, own API keys, own suppression list, while quota comes from one shared pool you control.
A tenant is an account
Each sub-account is a real account: its own credentials, domains, keys, and reputation surface. One client’s bad list cannot poison another’s deliverability. Depth is capped at one level. Sub-accounts inherit the parent plan and cannot spawn their own children, which keeps the hierarchy auditable.

}'One pool, allocated precisely
The parent’s monthly quota is the pool; each sub-account gets an explicit allocation from it. Over-allocating returns a 422 instead of overselling, allocation changes are row-locked against races, and deleting a sub-account returns its quota instantly. Aggregate analytics across all tenants stay root-only.
