Gmail will let you send emails with an expiry date soon

Google seems to gear up to bring a variety of features to Gmail.One of the major change is  to add expiry dates to emails on the service.

Soon there will be a new lock-shaped button added to the compose screen called ‘Confidential Mode’ that blocks other users from forwarding, copying, downloading and printing.

Users can also configure the expiration date of an email with all these added security functions, so that it will disappear after a week, month or even after a few years.It is also possible for the sender to confirm the recipient’s identity with a passcode via a text message.

Gmail will also be getting the ability to self-destruct an email. The email after a specified time becomes unreadable.
