1. Log in to the [Google Admin Console](https://admin.google.com/).

2. On the sidebar, go to **Apps** > **Google Workspace** > **Gmail** > **Compliance**.

3. Go to **Content Compliance** > Select **Edit**.

4. Add a **Content Compliance** filter, and name it `Email security - BCC`.

5. In **Email messages to affect**, select **Inbound**.

6. Select the recipients you want to send emails to Email security via BCC. Under **Add expressions that describe the content you want to search for in each message**:

   * Select **If ANY of the following match the message**.

   * Select **Add** to configure the expression.

     * Select **Advanced content match**.
     * In **Location**, select **Headers + Body**.
     * In **Match type**, select **Matches regex**.
     * In **Regexp**, input `.*`. You can customize the regex as needed and test within the admin page or on sites like [Regexr](https://regexr.com/).
     * Select **SAVE**.

7. In **If the above expressions match, do the following**:

   * Select **Modify message**.

     * Ensure that **Envelope recipient** > **Change envelope recipient** is unselected, so that emails will not be dropped as an unintended consequence. You will select this option at a later stage.

     * Go to **Also deliver to**, select **Add more recipients** > **ADD** > Choose **Advanced**:

       * Under **Envelope recipient**, select **Change envelope recipient** > **Replace recipient** > Enter the service address. This is the service address you copied and pasted in step 5 when [connecting your domains](https://developers.cloudflare.com/cloudflare-one/email-security/setup/post-delivery-deployment/bcc-journaling/bcc-setup/gmail-bcc-setup/connect-domains/). If you did not copy and paste the service address: - In [Cloudflare One](https://one.dash.cloudflare.com/), go to **Email security**. - Go to **Settings** and locate your domain under **Your domains**. - Select the three dots > **View domain** > **Service address**. Copy and paste the service address.
       * Under **Spam and delivery options**, select **Suppress bounces from this recipient**.
       * Under **Headers**, select **Add X-Gm-Spam and X-Gm-Phishy headers**.
       * Select **SAVE**.

8. In **Account types to affect**, select **Users** and **Groups**.

9. Select **SAVE**.
