An incorrect configuration resulted in emails not being delivered to the correct service. This was spotted in QA but pushed to production before the error was rectified.
The email ticket creator service could be updated to increment a counter each time an email is processed. If such metrics are added, our Operations team could then create a metric alert to notify us if the current processing rate drops below its expected value. A regression test has been added to internal instructions to ensure that services are being configured correctly going forward.
