# Schedule Messages

> Queue outbound messages for future delivery.

Messages can be scheduled for a specific future time. Scheduled messages appear in the Outbox with a `scheduled` status until delivery.

## Scheduling a message

Add a `scheduled_at` field in ISO 8601 format:

```json theme={null}
{
  "to": "user@example.com",
  "subject": "Your trial ends tomorrow",
  "scheduled_at": "2026-04-01T09:00:00Z"
}
```

## Canceling a scheduled message

Scheduled messages can be canceled before delivery via the dashboard or API as long as their status remains `scheduled`.
