Under to the cPanel account you want to use, click Manage.
In the Mail section, click Email Accounts.
Complete the on-screen fields, and then click Create Account.
NOTE: Your Mailbox Quota counts toward your account's Disk Space Usage.
After creating email accounts, you can either check them with webmail or use an email client.
I wouldn't suggest using cPanel as its notoriously spotty and you absolutely get what you pay for (cPanel email is a free addon.) I would suggest either using O365 or GSuite if you want a reliable email option. It's not free but $5 or so a month isn't too bad.
