An alias is a way to disguise another email address. Everything sent to an alias email address is actually received in the primary email account's inbox. Aliases can diversify a single email account without having to pay for multiple inboxes.
WHEN ARE EMAIL ALIASES USEFUL?
They can be not only useful but AWESOME! Here are a few examples for when you SHOULD consider aliases (we'll use real estate as an example):
Let’s say you are listing a house for rent on Craig’s List or trying to sell your car on Cars.com or ebay.com. Having a temporary Email Alias for this transaction can be useful for receiving inquiries as well as all the “junk mail” that comes through these websites. The good news, as soon as the house is rented, or the car is sold, you simply DELETE the Email Alias and immediately stop receiving ALL emails sent to that address.
Let’s say an employee (JSmith@company.com) leaves the company or is let go and you don’t need his Email mailbox anymore but you DO want to get future emails sent to his Email address. You can simply add JSmith as an alias to your own Email mailbox and from that point, any email sent to him, will arrive at your inbox. You can also use a simple outlook rule that can “paint” that email in a color that will tell you it was sent to JSmith.
Let’s say you want to post a job to an online directory. You can create a temporary Email Alias to use on job posting instead of using your official Email. You can also create a rule on outlook (or your other email client program) that will highlight any email that is sent to that alias, or set up an automatic reply to those people. Once the position is filled, you delete the Alias and no more online junk mail will arrive.
Let’s say you have a few roles in your company (email@example.com and CEO@legaltechnology.solutions)
Let’s say you want to track where emails originate from for a marketing activity such as advertisement. You can set up an Email Alias such as googleAd23@yourcompany.com. This will allow you to track all the emails that come from people who used ad #23 and so on.
