You are thinking if you can have an email address something like firstname.lastname@example.org? or anything you want? Well, it is possible! Just follow this steps and consider my advices.
Firstly, before going into the procedures, you should have your own domain name (ex: erickabuzo.com). If you don’t have, you can buy one HERE.
Considering that you have your domain and cpanel account,

2. If you have multiple domains, select the domain you want your email account to be associated with in the drop-down list in the top right corner and enter the desired email and a strong password of your choice:
Click on Create Account once all is set.
3. To log in your own webmail, visit in your browser’s address bar:
4. Once done, you will see the icons of the three webmail interfaces:
5. Feel free to choose any access webmail. I suggest Read Mail Using SquirrelMail.
