email alias vs email address – A email address is a completely separate email account with a unique username and login credentials. This means that you would have to manage two separate email accounts and log in to each one separately.
On the other hand, an alias is an additional email address that is associated with your existing email account. Emails sent to the alias will be delivered to your primary email inbox, and you can choose to send emails from the alias as well. This can be a useful way to manage multiple email addresses without having to log in to separate accounts. This is also a good way to hide your true email address when signing up for some online services.
What is an email alias?
When you send, reply to, or forward an email, sometimes you don’t want the recipient to see your primary email address.
An email account with alias addresses allows you to create multiple email addresses and customize the sender address of your messages.

This means you have complete control over what the recipients of your emails can see – and can quickly and easily send personal and business emails from the same mailbox. When you use email aliases, you don’t have to switch between accounts (and memorize or save multiple passwords), and you can set the sender address that you use most often as your default address. mail.com lets you have up to 10 email addresses in a single account, and our extensive list of over 100 domains means that you can customize your alias addresses according to your personal and professional needs.
What is an Email Address?
An email address is the identification of an electronic mailbox. It has two parts, namely, a local part and the domain. The local part usually contains the username of the user while the domain name depends on what email service provider you are using. The local part can contain words, numbers, or periods while the domain name depends on what kind of service provider you are using.

An email address uniquely identifies your mailbox as provided by your email service. When a message is sent to your email address, it’s collected by your email service and placed in a mailbox, which you access through your email account.
Email addresses are always in this format:
name@domain
The domain — the part after the “@” — is used to route email to the email service. The service is often obvious from the domain — such as outlook.com, gmail.com, and so on. The domain is used to identify the mail service1 handling its email.
As an email message is on its way from sender to recipient, the name — the part before the “@” — is completely ignored until it reaches the email service handling the email account. Once it arrives, the name is examined to see which account should receive the mail.
In our apartment building, the domain is like the street address: it gets the mail to your building. Your email account is your apartment. Your email address is like the apartment number. In the mailroom, the mail clerk uses your email name to place the message in the correct box.
An email address (also referred to as Real Name, Real Email Address or POP3 account) is basically an account located on an email server, where incoming emails are stored for the user of that account to get them. In order to see emails received on your email address, you must login with your logon name on the mail server of that account. In order to use emails, everyone needs an email address. It is like your postal mail address: if you wish to receive mail, you must supply a mail address.
email alias vs email address
An email address is a unique identifier used for sending and receiving emails. It typically consists of a username and a domain name (e.g., username@example.com).
An email alias, on the other hand, is an additional email address that forwards emails to a primary email address. It acts as a virtual forwarding service, allowing users to create alternative email addresses without setting up separate mailboxes. Aliases are useful for organizing incoming emails or creating multiple contact points that all route to a single inbox.
