# message.delivered

> Read the message.delivered data payload and its fields.

`message.delivered` fires when a message your agent sent reaches Delivered.

## Read the payload

This is a complete envelope as the staging agent received it. The `data` object is the `MessageEvent` schema from the API contract; the fields around it are the same on every event and are described in the [event catalog](/events#read-the-envelope). Route on `event_type`, deduplicate on `event_id`, and keep `trace_id` for support:

## Handle the event

Delivered means Relay accepted and stored the message; it says nothing about whether the person has seen it. Use `delivered_at` to update a status you show, and ignore the event if you show none. Read the [receipt rules](/messages/receipts) before you build anything on it.

## Next steps

* [Read delivery receipts](/messages/receipts)
* [Read the message.read event](/events/message-read)
* [Read the message.sent event](/events/message-sent)
* [Choose an event type](/events)
