Also, once hostname has been added, you need to deploy SSL for the server hostname using the option deploy SSL in the same page.

In this page, you can see all the records, including MX, A record and DNS authentication records such as DKIM, DMARC and SPF, all you want to select the CloudFlare account you integrated into CloudStick, then click on Add DNS records, this will automatically setup the required records in your DNS Zone in the case of CloudFlare users.
