It seems like today everybody wants your email address. Whether you’re trying to download a file, access a forum, or play a video, many sites now require you to give a real email address and then respond to a confirmation link to prove it. For anyone who wants to avoid their Inbox exploding with spam, giving away your email to everyone is not an ideal situation. How do you know which sites you can trust and which ones you can’t?

10 Minute Mail to the rescue. From the 10 Minute Mail creator…

“By clicking on the link below, you will be given a temporary e-mail address. Any e-mails sent to that address will show up automatically on the web page. You can read them, click on links, and even reply to them. The e-mail address will expire after 10 minutes.”

I have used this service a few times, it's quite usefull. 

The best thing of all… it’s completely free. Check it out.
