# Delete a one-time send

`DELETE /v1/newsletters/{newsletter_id}`

## Request

- URL: `https://api.customer.io/v1/newsletters/{newsletter_id}`
- Auth: HTTP bearer

Deletes an individual one-time send (referred to as a "newsletter" in our APIs), including content, settings, and metrics. It will be removed from segments, and its templates will no longer show in the Message Library.

If it's an in-app message, this cancels any undelivered, in-app message, too.

## Response `204`

Success. No content.

## Other responses

- `404`: The one-time send does not exist.
