Guerrilla Mail provides you with disposable e-mail addresses which expire after 15 minutes. You can read and reply to e-mails that are sent to the temporary e-mail address within the given time frame.
Every one of us has been in that bind where a site or service will ask you for your e-mail address and you just don’t want them to have it cause you’re tired of junk mail. Guerrilla Mail is free service that will answer your calls; it will create a timed 15 minute temporary e-mail account for you to use including a temporary mailbox that only requires a refresh to check it. Once you get your e-mail from the site you have signed up for, save the information and let your account time out. No more spam 
If you need a little more time to wait you can click a link for an additional 15 minutes added onto your timer.
