And each time you share your personal email address with a not-so-popular website, you run the risk of getting more spam.
Then came disposable email address services like SpamBox or Mailexpire, that let you create temporary email address which expire after a given time. These service forward all mails to your primary email inbox until the temporary email account expires.

A more useful player in the game is 10MinuteMail.com which actually provides a disposable email account and not just a use-n-throw email address.
With 10 Minute Mail, you get a temporary e-mail address. Any e-mails sent to this disposable address will show up automatically on the temporary web page that's visible only to you.
You can read new emails send to the disposable address and even reply to the messages using your new address. Read message are indicated with a tick. And everything expires after 10 minutes or more.
This is much safer since you no longer have to share your personal email with anyone, not even the disposable email service.

temporaryinbox.com is a similar service that offers both temporary inbox (as you could probably guess!) and also temporary forwarding. It's operated by the same guy that created mediaconverter.org.

I think www.mintemail.com is the best one. (1) You don't need to press copy because it automatically copies the email to your clipboard (2) You also don't need to refresh the page to check if your email has arrived because the webpage title is updated with you have new email... Check it out. You will never go back to the other sites which you are used to mintemail
