AddressGuard & disposable email addresses

Learn about AddressGuard, how to set it up, and how to manage disposable email addresses.


AddressGuard setup and management

AddressGuard is a powerful tool you can use to fight spam. You can use it to create up to 500 disposable email addresses to use when you don't want to reveal your primary email address. Messages sent to your disposable email addresses are delivered to your primary email inbox or to any personal folder you select. If a disposable email address begins receiving spam, you can simply delete that email address without affecting your primary address. Creating and deleting a disposable address is easy and convenient.

AddressGuard enhances your privacy by allowing you to give out an email address that is not visibly connected to you in any way. Not only is your inbox protected from spam, but your privacy is protected as well.
