How to Send Encrypted Email Gmail

Sending encrypted emails via Gmail can help protect your message’s content from unauthorized access. To do this, you can use a browser extension or third-party service, as Gmail does not provide native email encryption. One common method is to use a tool like “Virtru” or the “Confidential Mode” built into Gmail. Here’s how you can send an encrypted email using both methods:

Method 1: Using Virtru (Browser Extension)

Install the Virtru browser extension: Go to the Chrome Web Store (or the respective store for your browser) and search for the “Virtru for Gmail” extension. Install it.

Compose your email: Open Gmail in your browser, and click on “Compose” to start a new email.

Encrypt your email: In the email composition window, you will see a “V” icon next to the send button. Click on it.

A sidebar will appear. Click the “Encrypt Email” option.

Virtru will guide you through the process of encrypting your email. You can set a password, set expiration, and more.

Send the email: Once your email is encrypted, you can send it as you normally would.

Method 2: Using Gmail’s Confidential Mode

Compose your email: How to send encrypted email gmail  Open Gmail in your browser, and click on “Compose” to start a new email.

Enable Confidential Mode:

In the email composition window, you will see a lock icon at the bottom toolbar. Click on it.

A window will appear, allowing you to set an expiration date, require a passcode, and more.

Set access permissions: You can choose whether to require a passcode for access and how long the email will be available.

Send the email: Once you’ve configured the Confidential Mode settings, you can send the email. The recipient will receive a link to access the email.

For both methods, the recipient will need to follow the provided instructions to decrypt and read the email securely. Make sure to share the encryption password or passcode securely with the recipient if required. It’s important to note that while these methods provide a level of email encryption, they don’t offer end-to-end encryption like some other email platforms. If the highest level of security is a concern, you might consider using more secure email services or encryption tools that offer end-to-end encryption, such as ProtonMail or Signal.

Emails contain a plethora of personal and sensitive information. Whether you’re sending financial data, personal messages, or confidential work-related content, it’s crucial to ensure that your emails are secure and protected from prying eyes. One effective way to achieve this is by sending encrypted emails to Gmail.
