Did you know that you can send confidential, self-destructive mails with Gmail? In the last line of your Compose window, you will find this icon to Turn Confidential Mode On / Off. Once you switch on the Confidential Mode, the recipients won’t have the option to forward, copy, print, or download this email.
You can now set the expiration date of this email, in days, weeks, months or years. Once you set this, the email will automatically vanish from the inbox of the recipient after the prescribed time.
There’s more. You can even send a password by SMS, so that only the recipient or person who has the password, can open the email.
How’s that for confidential mail?
