How to Cre­ate Email Alias­es on Out­look, Yahoo Mail, and Gmail

Using our email addresses everywhere can't backfire anytime. That's why email services like Outlook, Yahoo Mail, and Gmail provide the facility to create an alias so that you easily manage newsletters and other signups without revealing your original ID.

As of 2020, the estimated number of email users was 3.9 billion. However, this means the average email user is exposed to spam emails daily. One of the best ways to deal with such emails is to create email aliases.

Email aliases are disposable email addresses. They help to add an extra privacy layer to your email account. You can also use them to sign up for newsletters or on websites that you aren’t sure of their integrity. Here’s how it works on the popular email services:

How to Create an Email Alias in Outlook

Outlook allows users to create an alias of an existing email account. This way, users can send emails and receive them through the alias. You can do this without switching accounts or making use of multiple emails. To create an email alias on Outlook, follow the steps below:

Step 1: Visit Add an Alias. If prompted, sign in to your Microsoft Account.

That’s all you need to do, but there are few things to note:

  • It is impossible to add a pre-existing address that is already associated with a school or work account.
  • The alias can only have numbers, letters, underscore, a hyphen, or a dot. No special characters or spaces can be used.
  • You cannot use an alias linked to another Microsoft account.

How to Create Email Alias in Gmail

Unlike Yahoo Mail and Outlook, Gmail doesn’t provide the option to create disposable email addresses. However, you can create custom email addresses that allow you to trace the source of a spam email. Here’s how it works:

Step 1: While signing up to a website or newsletter, you can create an alias by:

  • Adding a plus sign (+) to the end of your email address and including any text after it e.g. firstname+who@gmail.com;
  • Including a period (.) anywhere in your email address - firstname.lastname@gmail.com

The custom email addresses on Gmail aren’t private. However, they help filter the emails you get on Gmail and also track how your mail was given out.

Auto-Delete Emails

Although Gmail does not provide a feature for adding aliases or creating disposable email addresses, you can set rules to auto-delete emails.
