Use Gmail Plus-Addressing to Generate Throw-Away E-Mail Addresses

The following Tech-Recipes tutorial describes using the plus-addressing option on your Gmail account to create disposable email addresses.


Do not use this service from your main Gmail account. Eventually this trick will stop working, and your account will be flooded with spam.

Many services require email and email validation for use (i.e., forums, free I-tunes, free magazines, etc.). Some make money by selling your email address; therefore, you should not give them your main email address. Thus the need for throw-away or disposable email addresses is certain. Although many email providers offer this service, Gmail is an especially useful tool.

This information from wikipedia re Gmail explains how plus addressing works:

    Gmail also supports “plus-addressing” of emails. Messages can be sent to addresses in the form: [email protected] where extratext can be any string. Plus-addressing allows users to sign up for different services with different aliases and then easily filter all e-mails from those services. It does not appear, however, that the +string feature works when sending email from a gmail account to itself. Additionally (in some cases) the string appended to the e-mail address may not be longer than six characters.

If your gmail account is [email protected], then you can generate additional email accounts by adding text after the plus sign.

Original Account:
[email protected]

New Accounts:
[email protected]
[email protected]

By using Gmail’s filtering function with your unique text (dumpa, dumpb, etc.), you can automatically archive these messages if you start to see spam.

This likely will not work forever. Spammer and websites will soon learn to filter and remove this plus-addressing text. That is one of the advantages of Gmail. You can always sign up for another account.
