Have you ever needed an email .. NOW? Have you ever gone to a website that asks for your email for no reason (other than they are going to sell your email address to the highest bidder so you get spammed forever)?
Welcome to Mailinator - Its no signup, instant email. Here is how it works: You are on the web, at a party, or talking to your favorite insurance salesman. Whereever you are, someone (or some webpage) asks for your email. You know if you give it, you'll be spammed. On the other hand, you do want at least one email from that person. The answer is to give them a mailinator address. You don't need to sign-up. You just make it up on the spot. Pick firstname.lastname@example.org or email@example.com - pick anything you want (up to 15 characters before the @ sign).
Later, come to this site and check the email for that account. Its that easy. Mailinator accounts are created when mail arrives for them. No signup, no personal information, and when you're done - you can walk away. The emails will automatically be deleted for you after a few hours.
