Ah, got it. I’m not entirely sure I want to put that in, though. The message I’m “preaching” is that you have full decoupling with queues - not sure that should be diluted. Wouldn’t this kind of checking defeat the purpose of using the queue in the first place? It seems unlikely that Amazon would stop selling stuff just because the order-confirmation-email-sending-service was backed up, for instance. The point of using SQS would be that the sales system wouldn’t have to care.

In the universe of message queues, an email-per-sale queue is not going to be your problem. Think of the queue-as-message-bus pattern -- very common. You don't want to have a service with millions of pending messages to process, it forces you into painful, slow recovery, or making the tough choice of dropping everything. Anyway, great write up, and happy new year!
