To experience the benefits of Cloudflare, first create a Cloudflare account and add a domain to Cloudflare. When you create a new Cloudflare account, adding an initial domain is included in the workflow.
Click Create Account. Use an email alias or distribution list. For example, cloudflare@example.com. So, billing and service-relate email notifications are sent to this email address.
The Cloudflare UI will asks you to add a site to Cloudflare.
