How to unsend an email | Page 2 | Komando.com: Browser plug-ins

There are a few browser plug-ins that offer unsending features. The first one we're going to look at is Criptext.�Right now, it's just for Chrome and Safari, but Firefox and Outlook program versions are in development.

When you enable Criptext on an email, it�encrypts the message and any attachments, tracks it so you know when it's been opened, and gives you the option to "recall" it. You can also set messages to expire after a certain amount of time.

UnSend.it�is a service that works with more browsers and email services than Criptext. It does everything Criptext does, except encryption. You will also need to configure your email service to run through UnSend.it's servers.

Once that's done, you can send email and attachments to anyone. If you decide to unsend the email, just click a button in your email service and they won't see it anymore. You can also track when someone opens the message or set it to self destruct after an amount of time.

Both of these services work by turning the text of your message into an image, then sending that image on to your recipient. Because the message is served from their servers, they can delete the image and it will disappear from your recipient's inbox.

The email will still be there, but it will be blank. Unless your recipient took a screenshot, they won't have the information. If you really want to take things to another level, however, keep reading.
