Gmail already lets you recall sent emails with its Undo feature. Now, you can even send emails with a self-destruct timer through a Chrome extension called Dmail. If you send sensitive personal information and don’t want it floating around your sent box or your recipient’s inbox, you can set pre-defined timer on your message. You have your pick between an hour, a day, or a week. You can also decide to just delete it manually from your recipient’s inbox with the Revoke Email button you’ll be able to see on sent messages.

The service will work best if the receiver also has the extension but even regular Gmail users can see your messages through a link. Your recipient will be notified once the email “destructs” or gets revoked.
