So you are a high profile secret agent and need to send a really secure email to your party ;), you might want to try OneTimeMessage – a web-service that lets you send self-destructing emails to your friends.

There is no sign-up required. Just put in your and the recipient’s name and email address, write your secret message and send it. You might want to set additional options to send you a message when your email is read and when to destroy the message in case it remains unread.

The system then gives you a ‘key’ which you need to send to the recipient by any means of communication. Once the recipient reads the message, it destroys itself automatically within 5 minutes. I have used it and it’s really great.
