+special "dead-letter sub-queue" where it can be accessed using the `get_queue_dead_letter_receiver` function.

 ### Specific clients for sending and receiving
 In v7 we've simplified the API surface, making two distinct clients, rather than one for each of queue, topic, and subscription:
-* `ServiceBusSender` for sending messages. [Sync API](https://azuresdkdocs.blob.core.windows.net/$web/python/azure-servicebus/7.0.0b2/azure.servicebus.html#azure.servicebus.ServiceBusSender)
-and [Async API](https://azuresdkdocs.blob.core.windows.net/$web/python/azure-servicebus/7.0.0b2/azure.servicebus.aio.html#azure.servicebus.aio.ServiceBusSender)
-* `ServiceBusReceiver` for receiving messages. [Sync API](https://azuresdkdocs.blob.core.windows.net/$web/python/azure-servicebus/7.0.0b2/azure.servicebus.html#azure.servicebus.ServiceBusReceiver)
-and [Async API](https://azuresdkdocs.blob.core.windows.net/$web/python/azure-servicebus/7.0.0b2/azure.servicebus.aio.html#azure.servicebus.aio.ServiceBusReceiver)
