Difference between GoDaddy Workspace & cPanel Email

I have a Godaddy account.

As part of that I have workspace email. That allows me to create email accounts that correspond to the domains that I own with Godaddy. I can create a new email account called something@domainthatIown.com from the Workspace Email area (see screenshot).

Also, I have cPanel hosting. All the domains that I have registered with GoDaddy are hosted with cPanel. cPanel also gives me the option to create and manage email accounts (see screenshot).

For any given domain, what is the difference between creating/managing an email account via the Workspace, and via cPanel. I have noted that one could create the same email address using both places, but they would be completely unrelated. ( if I owned example.com I could create dude@example.com in my GoDaddy Workspace area, but also go to cPanel and create that same email address, but they would not be related).

What the heck is the difference?? How do I know which one to use? If I sent an email to dude@example.com would it arrive in my Workspace are, or in my cPanel area??

 

Ok. Wow. So the MX record effectively acts as the "switch" deciding which email interface is "active."

GoDaddy convinced me to pay for 10 WorkSpace email addresses (without a paid plan you cannot use IMAP). But now I wonder, if I switched the MX record to route email through cPanel instead, would I have unlimited access to and control over all the emails I needed? Did I get conned?
