# Restricting recipient email domains with allowlist

> Restrict email deliveries to recipients at approved domains.

The domain allowlist feature allows you to restrict [email deliveries](/share/deliveries/email) to specific email domains only. When configured, Omni will only send deliveries to recipients whose email addresses match one of the allowed domains. This is especially useful for maintaining control over where organizational data can be sent.

## Requirements

**Organization Admin** permissions are required to configure the domain allowlist.

## Adding domains to the allowlist

<Note>
  You can configure up to 10 domains in the allowlist.
</Note>

To configure allowed email domains:

<Steps>
  <Step noAnchor>
    Click **Settings > Deliveries > Email tab**.
  </Step>

  <Step noAnchor>
    In the **Domain allowlist** section, enter the domains you want to allow (for example, `example.com`).

    As you add domains, Omni displays a real-time **Impact on existing schedules** preview showing which schedules would be affected by the current allowlist configuration.
  </Step>

  <Step noAnchor>
    Review the impact preview. If any schedules would be blocked by the current allowlist, the **Save allowlist** button will be disabled. You'll need to either add more domains to accommodate those schedules or update the affected schedules first.
  </Step>

  <Step noAnchor>
    Once all existing schedules are compatible with your allowlist, click **Save allowlist**.
  </Step>
</Steps>

## Clearing the allowlist

To remove all domain restrictions and allow deliveries to any email address:

<Steps>
  <Step noAnchor>
    Click **Settings > Deliveries > Email tab**.
  </Step>

  <Step noAnchor>
    In the **Domain allowlist** section, click **Clear allowlist**.
  </Step>

  <Step noAnchor>
    When prompted, confirm the change.
  </Step>
</Steps>
