cPanel

Here’s how you can add a CNAME in cPanel:

1. Sign in to your hosting account’s control panel

2. Make sure the subdomain clients.example.com does not exist yet, otherwise delete it or choose a different subdomain

3. Open the DNS zone editor

4. Add a new CNAME record with these settings: 

   • Host: clients
     Value: domains.spp.io

5. Save your changes

You can find detailed instructions with screenshots on the cPanel website.
