It’s super-instant, always-ready, any-e-mail-you-want e-mail, right now. And with a name like mailinator, it’s bound to be good.
Mailinator provides sacrificial e-mail addresses that can be used when signing up for something that requires an e-mail address for confirmation. No passwords, no privacy, and no spam.
Even if you don’t use their service, their FAQ is entertaining. For example, “What if I send important emails with sensitive super-secret information in them to mailinator? Then you are a stupid-head. That isn’t what this is for.”
