To create email accounts you need to have access to cPanel.
Step 1
The first step will be to log in to your cPanel panel. Within your cPanel you must locate the Email section and then go to the "Email Accounts" item.

Step 2
On this screen, you must go to the option in the right corner under "Create"
Step 3

You are now on the account creation screen, just fill in the spaces with what is requested, creating a prefix according to the domain of your hosting account. We recommend at least one capital letter when defining the password to ensure considerable difficulty.
While setting the password, a difficulty counter is shown at the bottom.
Lastly, just click on Create !

A creation success message should be displayed .

Hope this helps !
