Email inboxes and inbound mail — support tickets from customer mail.
Email inboxes (GET/POST /workspaces/{org}/email-inboxes) give the workspace inbound addresses — mail to an inbox becomes a support ticket on the right channel, threaded by sender.
The worker’s inbound email route is configured on the Cloudflare side (Email Routing → worker). Replies from the app or API go back out through the configured send provider; missing provider credentials just disable outbound.
