Send & open confidential emails

You can send messages and attachments with Gmail's confidential mode to help protect sensitive information from unauthorized access. You can use confidential mode to set an expiration date for messages or revoke access at any time. Recipients of the confidential message will have options to forward, copy, print, and download disabled. 

Note: Although confidential mode helps prevent the recipients from accidentally sharing your email, it doesn't prevent recipients from taking screenshots or photos of your messages or attachments. Recipients who have malicious programs on their computer may still be able to copy or download your messages or attachments. This feature isn't available for G Suite customers at this time.
