Aliases, forwarding accounts and non-forwarding throwaway email addresses are all forms of disposable email addresses. Though, they are quite different from each other. In this blog post we will review and compare aliases, forwarding accounts and non-forwarding throwaway email addresses.

Aliases

Alias, in the context of email, is an email address provided by an ISP or email service provider that is mapped to a user's primary email address. For example, in Outlook.com, Yahoo or Gmail you can easily create aliases. Aliases are not separate accounts. Rather, they are just separate email addresses. When an email is sent to an alias, it is delivered to user's main account. Some providers allow delivery to a specially designated folder.

Example of an Alias

For example, if your Outlook.com email address is john.doe@outlook.com, you can get an alias agent007@outlook.com and email sent to agent007@outlook.com will be delivered to your main john.doe@outlook.com address. Aliases are easy to create and delete and thus they can be considered as a form of disposable email addresses. However, they are not as bad as throwaways email addresses.

Detecting Aliases

When it comes to detecting an alias, it can be easy or impossible. Here is why. When Outlook.com provides an alias, it the email address can be totally separate from your main address (as given in the example above). However, aliases in Gmail and Yahoo work a bit differently. In Gmail for example aliases are created by appending +aliasname to your main email address. Thus, if your Gmail address is john.doe@gmail.com, your aliases will be john.doe+alias1@gmail.com or john.doe+agent007@gmail.com and so on. As you can guess, in order to get a user's real Gmail address from her Gmail alias, you just need to remove the text between + and @ signs.

Forwarding Accounts

Forwarding accounts are email addresses created on a separate domain from user's main email domain address. Forwarding accounts as the name implies, forward email to user's real email address. Detecting forwarding accounts is very complicated unless the forwarding service provider is well known.

Non-forwarding Throwaway Email Addresses

Non-forwarding throawaway email addresses are truly disposable email addresses. They are created for one-time use. Currently there are dozens of disposable email address providers.
