An e-mail address identifies your e-mail account and server on the Internet. By sending an e-mail to "firstname.lastname@example.org," your friends, family, colleagues and business partners can send electronic mail over the Internet, which you can receive using an e-mail client or Web e-mail service. If you'd like to create your own customized e-mail address with your own domain name, you'll need to front around $10 to secure a domain name from a registrar. Using your e-mail, however, is absolutely free.
Open your Web browser and navigate to the website of a domain name registrar, such as GoDaddy, Register.com or Network Solutions.
Enter the domain name--the part of the address that comes after the @ symbol--of your choice into the search box on the website and click "Search" or "Submit." If your domain name is available, follow the step-by-step instructions to create an account and complete your purchase and register your domain name. Domain name registrations cost around $10 per year and can be registered for up to 10 years.
Log into the domain name registrar's website using the account you created in Step 2.
Click "Products" or "Services" from the home page once you're logged in. Choose "E-mail" and select the option to create a new account or e-mail address. Follow the instructions to create an e-mail address and select the domain name you registered as the domain that follows the "@" sign in your e-mail address.
Bookmark the Web e-mail page on your domain name registrar's website. You now have a custom e-mail address with your own custom domain name. Be sure to tell your contacts about your new e-mail address.
