title: SQL Server Native Delayed Delivery
summary: Describes the native delayed delivery implementation in the SQL Server transport

The SQL Server transport supports [delayed delivery](/nservicebus/messaging/delayed-delivery.md) by storing the delayed messages in a dedicated table. When a message delay time lapses, SQL Server transport moves messages from the sending endpoints to the destination queues in batches.

> [!NOTE]
> The native delayed delivery feature of the SQL Server transport is not available to [send-only](/nservicebus/hosting/#self-hosting-send-only-hosting) endpoints.
> The native delayed delivery feature of the SQL Server transport is not available to [send-only](/nservicebus/hosting/#self-hosting-send-only-hosting) endpoints as the delay logic is embedded in the receive component which is not initialized for send-only endpoints.
