Email domain? What is that exactly

An email address is made up of a username, an @ symbol, and a domain name. So, your email domain is the part of your email address that comes after the @ symbol, e.g., mail.com, usa.com, or any of the other 100+ free email domains listed below. Because the email domain is associated with a specific email server, your email domain tells the mail delivery system where to deliver the messages addressed to you. An email domain either comes from the email provider, e.g., mail.com, yahoo, etc., or a custom email domain can be purchased from a web hosting service.

How do you get an email address with a custom domain?

If you want a truly unique, customized email domain, you will have to go through an email hosting service, web hosting service, or website builder. These providers offer custom email domains for purchase, or for free in conjunction with a paid web hosting plan. However, a free customizable email address can be made using our wide selection of email domains below.

How does an email domain work?

The email domain is the part of your email address after the @ symbol. When you send an email, it first goes to a SMTP server. This outgoing mail server looks at the email domain of the delivery address to know which email server handles mails for that domain. It then transfers your message to the recipient server.

Are email domain names case sensitive?

No. You could type in [username]@Mail.com, @mail.com, or even @mAiL.com in an email address field and the message would still be delivered.
