Mailinator is a free disposable email service that offers email addresses under the domain @mailinator.com. Use your Mailinator address to sign up for websites, register software, post messages on message boards, or in any situation where you need an email address but don't want to give out your real address.
How to Use a Disposable Email Service (Preventing Spam)
The main advantage of Mailinator is that the addresses you create have no connection to your real email address. So when registration email lists fall into the hands of spammers (either accidentally, through hacking, or because a list is deliberately sold to spammers), you are protected from spam.
One advantage of using Mailinator is that it does not require any installation or registration. You do not even need to go to the Mailinator website to create the account. All you need to do is create an alias with the domain @mailinator.com and use it there (for example [email protected]).
To view mail sent to your disposable addresses, go to Mailinator's public inbox. Since no one uses a password, Mailinator is only useful if you don't want to communicate. All mail sent to Mailinator is public, meaning that every message sent there can be viewed by the public.
