2Prong is a very interesting Web 2.0 concept of a no-click disposable email system. By simply visiting the 2Prong web site the newly generated address automatically gets saved to your clipboard. Paste it in any form on a website that requires email verification and when the email is received it will pop up instantly in the box on the 2Prong site. 2Prong changes the domain weekly in order to prevent the address from being banned, a problem which plagues other disposable email services.
This service works flawlessly, the only thing to note is that between the headers of the received e-mail and the content of the message is a leaderboard containing Google Adsense ads. As this is a totally free service, this fact should not bother anyone. 2Prong is a great tool to use when you are on a public system and don't want to login to your real mailbox to receive e-mails.
Trashmail - www.trashmail.net/
Trashmail has a similar concept as Jetable, but offers some extended setup options. The service offers options such as while creating a disposable e-mail you can set the number of forwards this e-mail can take, life span that is considerably larger (form 1 day to 6 months) as well as challenge response spam filtering.
After creating a disposable e-mail address, the service gives you a unique (https) link where you can even change the address settings. There is also a Firefox extension for this service (available at Mozilla).
Spam.la - www.spam.la
This online service should be used just for non important throw-away site registrations as all the e-mails sent to the address you chose will be publicly readable on spam.la homepage. Quite a lot of people are using the service, so you can easily filter the listing with your own disposable address to see the actual mail you received.
This were just some of the unique disposable e-mail services, but I tried to cover just those which don't need user registration. If you are interested in other alternatives - Google is your friend.
