2. Click **Configure** on the Dashboard.
3. Click the gear icon to open the **Manage Service** menu and click **Create**.

Set the options as follows:

* **Domain:** `email.example.com` *Enter your branded link domain here. Ensure it matches the domain configured in the SendGrid link branding settings. This value will be what recipients see in your SSL enabled click tracking links.*
