As part of the newly redesigned Gmail experience, Google is experimenting with a feature that will allow email users to send off self-destructing emails. These emails will expire after a certain amount of time, making them unreadable by the recipient.
With this new feature, Gmail users will be able to access a "confidential mode," which means that the email recipient will not have the ability to forward the email, copy and paste its contents, or download or print the email.
The self-destructing emails may be configured to disappear within time limits of a week, a month, or years at a time. For an added level of security, users may also ask their email recipient to confirm their identity with a passcode that is sent via a text message.
