How to Encrypt Email in Gmail: 3 Easy Ways

Introduction:

Email encryption protects your messages so only the intended person can read them. It protects sensitive information from cyberattacks and unauthorized access while ensuring privacy and full compliance with applicable regulations. This article explains how to encrypt email in Gmail with three easy-to-follow approaches.

Way 1. Encrypt Gmail with Confidential Mode

Confidential Mode in Gmail is a quick way to add additional protection for sending private or sensitive emails.  While it isn’t true end-to-end encryption like certain dedicated secure mail services—but it still limits recipient actions.

You can stop forwarding, copying, printing, and downloading, define an expiration date, and require a passcode to open the email—ensuring an additional layer of protection and privacy.

Let’s see how to encrypt email in Gmail via Confidential Mode in a few clicks.

Step 1. Open Gmail and tap the Compose button.

Step 2. In the New Message window that opens, tap the padlock icon in the bottom-right corner.

Step 3. In the Confidential Mode window, set the email's expiry period under Set Expiry.

Step 4. In the Require Passcode section, choose No SMS passcode or SMS passcode (to make your email more secure).

Way 2. Encrypt Gmail with Client-Side Encryption

Client-Side Encryption (CSE) in Gmail lets you encrypt the content of your emails in your browser before it’s transmitted to Google’s servers, giving you stronger control over sensitive message data.

Enabling CSE ensures the email body and attachments are encrypted so only the recipient can decrypt and read them — meaning Google itself cannot view the encrypted message content.

Learn how to send a secure email in Gmail with Client-Side Encryption in just a few clicks.

Step 1. Launch Gmail and click the Compose button to start.

Step 2. Click Message security located in the top-right corner of the message.

Step 3. Under "Additional encryption," tap Turn on.

Step 4. Then add your recipients, subject line, and message content. And press Send. When asked, access your account through your identity provider.

Way 3. Send a Secure Email Using Extension (Virtru or Proton)

Even with Gmail’s encryption, if greater security and control over your messages are required, you can turn to a third-party extension like Virtru or a secure email service such as Proton.

By connecting with Gmail, these tools offer end-to-end encryption so that only you and the recipient can access the email — excellent for sending sensitive or highly confidential information safely.

Step 2. Open Gmail and hit Compose.

Step 3. Turn on Virtru by tapping the toggle switch at the top-right of the compose window (blue).

Step 4. Hit the gear icon to set the expiration date, disable forwarding, and add a watermark. After configuring the settings, press Secure Send.
