# Cancel a Broadcast

> How to cancel a scheduled campaign or halt an in-flight broadcast in Mailofly.

# Cancel a Broadcast

If you notice an error in your template, audience segment, or scheduled launch time, Mailofly allows you to cancel upcoming or currently sending broadcasts.

***

## Cancelling a Scheduled Broadcast

Broadcasts scheduled for future delivery can be cancelled at any time before dispatch:

1. In your dashboard, navigate to **[Campaigns](https://www.mailofly.com/user/campaigns)**.
2. Locate the campaign in the **Scheduled** tab.
3. Click the actions menu (`...`) and select **Cancel Campaign**.
4. The campaign status reverts to **Draft** or **Cancelled**, and no messages will be dispatched.

***

## Cancelling In-Flight Sends

For broadcasts currently sending:

* Batches already dispatched to recipient MTAs cannot be recalled once accepted by destination mail servers.
* Selecting **Cancel** halts any pending batches waiting in the queue, preventing remaining contacts in the segment from receiving the message.

***

## Cancelling via API

You can also cancel a scheduled email or campaign programmatically:

```bash cURL theme={null}
curl -X POST https://api.mailofly.com/api/v1/emails/em_123456/cancel \
  -H "Authorization: Bearer mf_live_your_api_key"
```

Response:

```json theme={null}
{
  "id": "em_123456",
  "status": "cancelled"
}
```
