Mail Tweet Share Email When you want to send emails that contain private information, use confidential mode in Google Gmail to send messages that automatically disappear after a specified amount of time. Gmail confidential mode also prevents recipients from forwarding, copying, printing, or downloading the message contents. Confidential emails can be sent to other Gmail users or those who use a different platform such as Outlook, iCloud, or Yahoo. How to Use Confidential Mode to Send Emails in Gmail If you use the official Gmail website to send emails, use the confidential mode in the compose window. Go to the Gmail website and log in with your username and password. Select Compose. At the bottom of the compose window, select the Confidential Mode icon (the lock with a clock on it). Choose when the message will expire, then select Save. For extra security, select SMS passcode to require recipients to enter a code sent in a text message to their device before they can open the email. Compose the email, then select Send. How to Use Confidential Mode in the Gmail App If you compose emails on the go with the Gmail mobile app for either iOS or Android, you can also quickly send confidential content while in confidential mode. Open the Gmail app and log in with your username and password. Select Compose. Select the More icon (the three horizontal dots). Select Confidential mode. Select when the message will expire, then tap Save (or the Check mark icon on some devices). Just like the Gmail website, you have the option to require all recipients to enter a code sent in a text message before they can open the email. Tap Edit after returning to your message to change the expiration date. Compose the email, then select Send. How to Open a Confidential Email in Gmail If you use Gmail, open a confidential email the same way you open a regular email on the website or mobile app. If the email requires a passcode, you'll receive a text message with the code. If you're not a Gmail user, follow the confidential email link to request a passcode. Then, enter the passcode found in the text message sent to your device to view the message's contents. While Google has placed precautions in their system to prevent confidential emails from spreading, receivers may take a screenshot of the information or use malicious software to bypass security restrictions. Take caution when sending any private data over the internet.
