# Using Fastly as your Content Delivery Network (CDN)

To use Fastly as your CDN for SSL click tracking, create a Fastly service that points to SendGrid, then ask SendGrid support to enable SSL click and open tracking:

1. [Sign up for Fastly](https://www.fastly.com/signup/) or [log in](https://manage.fastly.com) to an existing account.
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:

* **Server address and port:** `sendgrid.net` : `443` *The connection on the SSL port 443*
* **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.*
* **Description:** `SendGrid` (or whatever you like)

Finally, click the **Create**. The new service will appear in the list of available services.

Contact SendGrid support to validate your CDN settings and enable SSL click and open tracking.
