You can easily create your own email account(s) on cPanel, your web hosting control panel.  All UltimateWB web hosting packages come with at least 1 custom email address.  Your email address will be in the form of your_name@your_website.com, where "your_name" is whatever you choose, and "your_website.com" is your domain name.

1) Login to your web hosting control panel (refer to logging into cPanel tutorial here).

2) From your web hosting control panel, click on the "Email Accounts" link/icon:

3) Here, you create your email account:

In the "Email" field you enter in the first part of your email address, the part before the "@your-domain-name.com" part.  Here the domain name is "sample-website.com".  Choose a password, and then confirm your password.  You can also click on the "Password Generator" button to have this tool create a password for you to copy/paste to use.  Then set a mailbox quota, and click on the "Create Account" button.  And done!  Repeat as you would like to create more email accounts, based on the web hosting package you chose/how many email accounts it comes with.
