First, please log in to your Hosting Control Panel as described here.
Now find the email Accounts Icon.
I find it easiest to use the search function on the top. In this case, start typing EMail in that box. Next, click on the Email Accounts Icon:
Next, click on the +CREATE button.
On the page that appears, choose the domain name you want to create the email address at and fill in the fields as you wish:
Click +CREATE on the bottom of the page to complete the process.
Your E-Mail address is now ready to send and receive Email.
To access your newly created email address, go to https://cp.helpinghost.net:2096
(OR to https://webmail.yourwebsite.com )
