# Cancel or reschedule an email

`PATCH /email/{id}`

## Request

- Base URL: `https://www.unitpost.com/api/v1`
- URL: `https://www.unitpost.com/api/v1/email/{id}`

Cancel a scheduled or queued email, or move it to a new send time. Only emails that haven't been handed off for delivery yet can be changed — once an email is sent this returns `409`. Look up the email's current state first with [Retrieve an email](#get-email-id). Requires the `emails:send` capability.
