# DELETE /email-campaigns/:campaign_id/sends/:send_id

**Resource:** [Email Campaigns](./email-campaigns.md)  
**MCP tool:** `cancel_email_blast_run`  
**Scopes:** `email-blasts:delete`  
**Write operation:** yes

Cancel a SCHEDULED run of an email blast so it never sends, and remove it from the Runs list. Only runs with status 'scheduled' can be cancelled; a run that has already sent (or is mid-send) is a permanent record and cannot be removed.

## Parameters

| Name | In | Type | Required | Description |
|------|----|------|----------|-------------|
| `campaign_id` | path | string | yes |  |
| `send_id` | path | string | yes | The scheduled run to cancel, from list_blast_runs. |
| `require_approval` | query | boolean | no | Optional. Set true to route this write into the approval queue for human review instead of executing it immediately (returns 202 + an approval_id). Works even when your key/token has permission to execute directly. |

## Request example

```bash
curl -X DELETE   "https://api.trustpager.com/functions/v1/api/v1/email-campaigns/:campaign_id/sends/:send_id"   -H "Authorization: Bearer YOUR_API_KEY"
