# Use your Oracle Dyn Account

You can use your Oracle Dyn account to send email through Customer.io with no loss in functionality. To take advantage of Oracle Dyn, you need to do two things:

1.  [Point Oracle Dyn’s webhooks at Customer.io](#webhooks).
2.  [Configure Oracle Dyn as a custom SMTP server in Customer.io](#custom-smtp).

### Point Oracle Dyn’s webhooks at Customer.io[](#webhooks)

1.  Go to the [Oracle Dyn Integrations page](https://email.dynect.net/index.php?Page=Integration).
    
2.  Add the following webhook URLs for every domain you want to send mail from in Customer.io. If your account is in the EU region, substitute `track-eu.customer.io` in the URLs below.
    
    *   **Bounce Postback URL**: `https://track.customer.io/oracledyn/events?event=bounced&dyn_cio_email_id=@X-CIO-Email-ID&email=@email&bounce_type=@bouncetype&reason=@bouncerule`
    *   **Spam Complaint Postback URL**: `https://track.customer.io/oracledyn/events?event=spammed&dyn_cio_email_id=@X-CIO-Email-ID&email=@email`

3.  In the **Custom X-Headers** section at the bottom of the page, add `X-CIO-Email-ID`.

### Create your SMTP API Credentials[](#api-key)

If you don’t have your credentials handy, find your account on the Oracle Dyn [Users Page](https://email.dynect.net/index.php?Page=Users) page, select your user account, and update your SMTP password. This integration uses port 587. If you need to use a different port, you should use a [custom SMTP integration](/journeys/use-your-smtp-server/).

[![Set a SMTP password](https://docs.customer.io/images/smtp_password.png)](#3ae132f1d8711d8d1d3305883e580c60-lightbox)

Save or copy your new password. You will need it to configure Oracle Dyn as your SMTP server in Customer.io, and you can only access it once!

### Configure custom SMTP settings[](#custom-smtp)

Before you begin, you need your SMTP password. If you don’t have your SMTP password, you can [generate a new one](#api-key).

1.  Go to [**Settings** > **Workspace Settings**](https://fly.customer.io/workspaces/last/settings/).
    
2.  Click **Email**, click **Custom SMTP Settings**, and then click **Add Custom SMTP Server**.
    
    [![Custom SMTP settings page](https://docs.customer.io/images/smtp_settings_no_servers.png)](#e716d23f8203dc611fab77ba40838a5f-lightbox)
    
3.  Select **Oracle Dyn** and click **Continue to set up**.
    
4.  If you haven’t set up webhooks yet, copy the URL on the **Set up webhooks** tab and then [set up webhooks](#webhooks) to report message metrics in Customer.io.
    
5.  Click **Add Credentials** and enter your Oracle Dyn credentials.

6.  Click **Finish set up**. Your account is now set up to send email through Oracle Dyn. If you have any questions or feedback, [contact us](https://customer.io/contact/) and we’ll be happy to help!
    

 Configure multiple servers to use both transactional and broadcast streams

If you have a Premium Customer.io plan, you can configure [multiple custom SMTP servers](/journeys/multiple-smtp-servers/) and assign one to each of your Oracle Dyn server types.
