If the domain uses our nameservers, edit DNS in cPanel Zone Editor:
- A — points a hostname to an IPv4 address (the website server)
- CNAME — alias to another hostname
- MX — where email is delivered
- TXT — SPF, DKIM, and domain verification
Wrong MX records will break email. After saving, allow time for propagation. If the domain is still on another registrar’s nameservers, change records there instead.
