If you want to send a message to someone but don’t want anyone to keep a record of it, you need Vanishing Message. It is a free tool that allows you to send a message without anyone being able to save it. It can come handy in situations where someone tells you something and you ask for Proof. 😉
Here is how it works, you run the program, type the message, hit Save Message, and then exit. Attach the Vanishing Message program file to a new email and send it to anyone you want. He/She will download the attachment and press Reveal Message. The message will be displayed for one minute only, after that it will self-destruct. It will also vanish if the receiver closes the program. Update: Sorry, you have to attach message.xvm file, not the original program.
Note: The message is encrypted securely when you press Save Message button and decrypted when the receiver presses Reveal Message.
The screenshots below show the complete process.
According to the developer, you must not reply to the same message. Just send a new message or use Forward option for better security.
