  this feature.

  <span />

  Once you have access, upgrade your Resend SDK to use the methods on this
  page:

  <CodeGroup>
    ```bash Node.js theme={"theme":{"light":"github-light","dark":"vesper"}}
    npm install resend@6.18.0-canary.0
    ```
  </CodeGroup>
</Warning>

<QueryParams type="suppressions" isRequired={true} />

<ParamField query="origin" type="bounce | complaint | manual">
  Filter suppressions by origin.

  Possible values:
  `bounce`: emails suppressed automatically after a bounce
  `complaint`: emails suppressed due to a user complaint
  `manual`: emails suppressed by your team manually
</ParamField>

The `source_id` in the response references the email that triggered the
suppression. For suppressions with a `manual` origin, `source_id` is `null`.

<RequestExample>
  ```ts Node.js theme={"theme":{"light":"github-light","dark":"vesper"}}
  import { Resend } from 'resend';

  const resend = new Resend('re_xxxxxxxxx');

  const { data, error } = await resend.suppressions.list();
  ```

  ```bash cURL theme={"theme":{"light":"github-light","dark":"vesper"}}
  curl -X GET 'https://api.resend.com/suppressions' \
       -H 'Authorization: Bearer re_xxxxxxxxx'
