Email Workers

Email Workers lets inbound mail trigger a Worker. You can parse, route, forward, or reject the message, or start another process from it. Support ingestion, replies by email, and alert deduplication become small functions instead of jobs for a mail server or parsing service.

Email is just another event type, so the integration is clean. Storing attachments in R2 or handing work to Queues feels natural.

Local development and testing remain awkward, and you will send more real test emails than you would like. Message size limits and thin debugging tools cost it points too. Still, it turns email into an API for free.
