Protect messages with confidential mode

Need to send sensitive content to people? With confidential mode in Gmail, you can protect sensitive information from unauthorized access. Set an expiration date for messages, revoke access to messages and attachments at any time, and disable recipients' access to forward, copy, print, and download material. Note: Confidential mode helps prevent recipients from accidentally sharing your email. However, it doesn't prevent recipients from taking screenshots or photos of your messages or attachments. Recipients who have malicious programs on their computer might still be able to copy or download your messages or attachments. Important: Confidential mode messages can't be scheduled to send later.

Use confidential mode to send messages and attachments

Open Gmail and click Compose. At the bottom of the window, click Turn confidential mode on . Note: If you already turned on confidential mode for an email you’re drafting, open the email and click Edit. Under Set Expiration, click the Down arrow  and select a date. Under Require Passcode, choose an option: No SMS passcode—If a recipient uses Gmail, they can open the message directly. Recipients who don't use Gmail get a passcode by email. SMS passcode—Enter the recipient’s phone number. A passcode will be sent by text message. Click Save. If you’ve selected SMS passcode, enter your recipient’s phone number. Click Send.
