SPF includes and multi-tenant infrastructure
SuccessFactors publishes SPF include mechanisms that authorise its sending infrastructure to dispatch emails on behalf of customer domains. Because it operates as a shared, multi-tenant platform, multiple customer organisations' outbound mail passes through overlapping sending IP pools, meaning individual domain reputation is bundled with other tenants' sending behaviour—a consideration for senders evaluating authentication and bounce-handling across their email stack.
