IAI-Shop (PL) frequently appears in SPF records alongside Google Workspace, a pattern typical of smaller organisations deploying a specialist regional email service as a supplement to or alternative for Google's platform. This dual-provider approach creates SPF include chains requiring senders to account for both providers' IP ranges, and mailbox providers must resolve both includes to validate authorised mail sources. For organisations maintaining such setups, careful management of SPF chain depth and include order is important to maintain delivery reliability and avoid exceeding SPF's practical query limits.
