Google has announced that it will be bringing the Gmail confidential mode to G Suite by default on the 25th of June 2019.
The feature will be made available to all users who will be able to send emails using the confidential mode.
Confidential mode provides built-in information rights management controls in your emails by allowing senders to create expiration dates and revoke previously sent messages. Because a sender can require additional authentication via text message to view an email, it’s also possible to protect data even if a recipient’s email account has been hijacked while the message is active. Additionally, with confidential mode, recipients don’t have the option to forward, copy, print, or download their content or attachments.
