I need to delete hosting on cPanel to set up Managed Wordpress Websites. If I reset the cpanel will that also reset the email provided with Go Daddy? Are they linked or is the GoDaddy provided email separate?
yes it will, that's why it's called reset, it resets everything. It also gives a new IP address for your domain. Please be aware of this. Make full backups before you use reset.
Not all problems need you to reset, ask if not sure.
