Turn queue messages into HTTP calls
A bridge from the broker to a webhook — the shape most third-party systems expect.
In detail
MailerQ publishes results to queues; many systems want a POST. This tool is the adapter, and it is how a customer's own application would receive delivery results without an AMQP client. Hub reads the queues directly, so we do not need it. It becomes interesting only if we offer customers their own result feed, which is a product question rather than a technical one.
