Create Email Alias

What is an Email Alias?

Simply put, an email alias is an alternate email address. Messages sent from, or sent to the email alias, are actually being sent and received from/to an original and existing email account.

Why use an email alias?

Here are some reasons:

  • Simply your email usage by receiving email sent to a unique (alias) address, in addition to your current email address, in the same (original) email account. In many cases, visually scanning emails in one account is faster than scanning emails in numerous email accounts.
  • Setup and maintenance of multiple email addresses all linked to a master email account is much simpler than setting up and managing multiple unique email accounts.
  • To create a simple replacement for a long and to difficult to remember email address.
  • Privacy through filtering. David Nield discusses this thoroughly in his article, Email aliases are the easiest path to privacy—and an organized inbox (, 11/11/2018): “… the real application here is not anonymity, but easy filtering. For example, if you sign up for a lot of email newsletters, consider doing so with an alias. That way, you can quickly filter the incoming messages sent to that alias—these are probably low-priority, so you can have your provider automatically apply specific labels, mark them as read, or delete them immediately. Alternatively, a filter might prioritize messages sent to the alias you give out to friends and family, or those sent to the alias you use for work emails. This approach gives you a lot of flexibility for managing your inbox. [Promethious note: On some email clients you can set up “Smart Folders” where incoming email for an alias account is routed both to the original account and to the “Smart Folder]. Keep in mind that recipients can usually look at one of your aliases and use it to figure out your main email address. So in situations where anonymity is critical, you might need to set up a whole new account. Still, if hiding your identity doesn’t matter as much, aliases are much easier to configure than whole new accounts. “

Set up an email alias on your mail server

An email alias is first created in your mail server, and then, configured in your email client. For this demonstration, I will use as a mail server and Spark as the email client. It is assumed an email account is already established on the selected mail server, and the email client is already installed with the email account configured.

To set up your mail server, log into and select the Mail icon from the application’s page. Next, click the gear icon in the lower left-hand corner of the side panel (See image below).

On the next window, click on Accounts, then Add an alias.

After clicking Add an alias, the following window appears:

Here, type in the name of the alias, and then re-type it in the Full Name field. Then click: OK. The mail server is now set up.

Set up an email alias on your mail client

For the Spark email client, start-up Spark, and in the upper left-hand corner of your screen, on the toolbar, click Spark. Then click on Preferences in the drop-down box. After this, you get the window below:

At the top of the window, click the Accounts button (1.). In the left panel, highlight the name of the email account where the email alias account will be linked to (2.), then press the Alias button near the top of the right panel (3.).

In the next window, click the “+” button in the center of the right panel. Now fill in the Name you used when you set up the alias on the mail server, next, in the Alias box, type in the alias account address you created in the mail server. Now click out. Your email alias account is now set up in the Spark mail client.

Using an email alias

Before you create an email alias, think the process through. In most cases, your goal is to simplify your email usage, not complicate it. As you can see, email alias’s are easy to set up. All emails from the alias account will go to the original account. Though setup options can very, the email’s alias can be used almost like any other mail account. For incoming mail, you can differentiate between emails in the original email account by looking at the email headers, or if you use “Smart Folders” linking to your alias’s, your alias’s email will be in it’s own folder. For outgoing mail, when you compose an email using an alias, just remember to set the “From” address in the composition to the email alias.
