# Delete alert API

> Delete an alert and its delivery history. Frees a slot against your plan's alert limit. Free.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="Does deleting free up my alert quota?">
    Yes. The plan cap counts every saved alert regardless of status, so deleting is the only way to free a slot — pausing does not.
  </Accordion>

  <Accordion title="Is the delivery history kept?">
    No. Deliveries cascade with the alert. Export anything you need from the [delivery log](/docs/api-reference/alerts/alert-deliveries-api) before deleting.
