# Disable email sending for a domain

`DELETE /api/apps/{app_id}/custom-email-domains`

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Turns off email sending for a domain.

The domain itself stays connected to the app and keeps serving the site. Only the ability to send mail from it goes away, and mail falls back to Base44's own sending address.

Base44 also tries to remove the domain from the mail provider, but a successful call doesn't promise that part succeeded. If the provider can't be reached, the local configuration is still removed and the call still succeeds.

This removes the domain's email setup rather than pausing it. To send from the domain again you run [Enable email sending for a domain](/api-reference/enable-email-sending-for-a-domain), publish DNS records, and wait for verification, the same as the first time.

The response body is empty, so read the status code.

## Path parameters

- `app_id` string, required — ID of the app whose email domains you want to work with.

## Query parameters

- `domain` string, nullable — Domain to delete. Required when multiple domains exist.

## Response `200`

Email sending is off for this domain. The body is empty.

- DeleteEmailResponse — Response for deleting email domain.

## Other responses

- `400` — This app has more than one email domain and you didn't say which to act on. Send `domain`.
- `401` — Missing or invalid credentials.
- `403` — You don't have access to this app, you used a workspace API key, or the email domain is suspended. A suspended domain says why in the message.
- `404` — This app has no email domain set up, or none matching the `domain` you sent.
