4. Teammate is alerted
5. No rule matches  (on the connector from "Rule assigns a queue" to "General queue")
6. General queue
7. (manual triage)  (second line of the "General queue" card)

SHORT TEXT ALTERNATIVE (the alt text of the image in index.html)
Support email routing diagram. The steps are listed below it.

LONG TEXT ALTERNATIVE (the visible list under the diagram)
1. Email arrives: a customer email lands in the shared support inbox.
2. Rule assigns a queue: a routing rule reads the subject line and assigns Billing or Technical.
   - No rule matches: the email goes to the general queue for manual triage.
3. Teammate is alerted: the person covering that queue gets a notification.
