In a world where data breaches, identity theft, and cyber attacks are on the rise, protecting your online communications is no longer a choice—it’s necessary. When sharing sensitive personal data, financial data, or business agreements, email security must always be a priority.
That is where Gmail Confidential Mode steps in—a native option that allows the sending of emails with increased privacy options, with more control over who views your message, how long they view it, and whether it is possible to share.
If you’re just starting to use Gmail Confidential Mode or just want to learn the basics of using it effectively, you’re on the right page. In this article, we’ll dissect everything you need to know, from enabling Confidential Mode to its most important features, advantages, disadvantages, and why it’s important today.
For a step-by-step guide in detail, we strongly advise you to read the original post on ExtractMail blog.
❓ What Is Gmail Confidential Mode?
Gmail Confidential Mode is a feature that Google launched in 2018 to enable users to send emails with inherent information protection controls. It’s designed to prevent sensitive material from being forwarded or viewed forever.
Here are the ways Confidential Mode operates differently:
-
✅ You can apply an expiration date on your email.
-
✅ You can ask for an SMS passcode for extra security.
-
✅ The recipients won’t be able to forward, copy, download, or print the contents of your email.
-
✅ You can stop the plug at any moment—even after you’ve sent the message.
It’s as if it provides you with greater mastery over your emails, securing your info even when it leaves your outbox.
❓ Why Gmail Confidential Mode?
Email remains one of the most popular communication tools both in business and in daily life. But standard emails aren’t necessarily secure—anyone who has them can forward them or print them out, and once they’re out, they’re usually out of your control.
These are some typical situations where Gmail’s Confidential Mode is particularly helpful:
-
📄 Sending legal documents to clients
-
💳 Sending your accountant your personal financial information
-
🧾 Emailing internal memos with sensitive business strategies
-
🔐 Sharing login credentials or personal identification info (though this is still not ideal over email)
The goal of Confidential Mode is to minimize data exposure and reduce the risk of unintended sharing.
✉️ How to Use Gmail Confidential Mode (Step-by-Step)
Using Confidential Mode in Gmail is very straightforward. Here’s how to do it:
1. Open Gmail and Start a New Email
Click “Compose” like you would when you send a normal email.
2. Turn on Confidential Mode
At the bottom of the compose window, there is an icon made up of a lock and a clock. Click on this icon to turn on Confidential Mode.
3. Configure Your Preferences
You will be prompted to:
-
Set an expiration date (1 day to 5 years)
-
Select whether to request an SMS passcode or grant access through Gmail sign-in
4. Send Your Email
Tap “Save,” complete your message, and tap “Send.”
If you chose “SMS Passcode,” the recipient receives a text message with a verification code before seeing the email.

🔑 Key Features of Gmail Confidential Mode
Let’s dig in deeper into the key features that distinguish Gmail Confidential Mode:
-
✅ Set Expiry Dates
Self-destruction of emails after a period of time. Excellent for time-limited information or temporary document usage. -
✅ Block Forward and Copy
Once Confidential Mode is switched on, recipients will not be able to forward, copy, print, or download what is inside. Avoids loss of data by mistake or intentionally. -
✅ Revokes Access Anytime
Even after a message has been sent, access can be removed at any time. Just choose the sent message and click on “Remove access.” -
✅ SMS Verification
As an additional measure of protection, you can ask the recipient to verify themselves by a one-time SMS passcode. This is particularly useful when emailing third parties or your organization and domain.
👥 Use Cases: Who Can Benefit from Confidential Mode
Anyone who sends confidential or private data can gain from it, but here are some notable user groups:
-
Freelancers & Consultants: Sending contracts or project scope
-
HR Departments: Sending offer letters, salary information, or employee records
-
Lawyers & Accountants: Sharing confidential legal or financial papers
-
Students & Educators: Sharing transcripts or official communication
⚠️ What Gmail Confidential Mode Can’t Do
Despite Gmail Confidential Mode providing an additional layer of protection, be aware of its limitations:
-
❌ No End-to-End Encryption
Confidential Mode is not using end-to-end encryption. Google still has access to the content of the message. -
❌ No Screenshot Protection
Receivers can always take a screenshot or image of the email using another device. -
❌ Attachments are Restricted
You can’t attach downloadable attachments in Confidential Mode. Recipients can see content only within Gmail directly. -
❌ Only Works With Gmail or Supported Email Clients
Some third-party email users might not have an out-of-the-box experience or need to authenticate on another web portal.
🔐 And although Confidential Mode is useful, it is no substitute for enterprise-level encryption tools such as ProtonMail, Tutanota, or secure file-sharing apps.
🔒 How Safe Is Gmail Confidential Mode Anyway?
From a usability point of view, Gmail Confidential Mode is well tuned to balance between control and usability. It is not the most secure thing on earth, but more secure than sending sensitive-content emails in cleartext.
It works best when being used together with other security good practices, which are:
-
🛡️ Keeping strong, non-dictionary-attacked, unique passwords
-
🔐 Activating 2-factor authentications
-
🧾 Encrypting sensitive material before attachment
🧾 Gmail Confidential Mode and Compliance
If you’re in a compliance-regulated industry (such as GDPR, HIPAA, or CCPA), Gmail Confidential Mode can assist—but not ensure—compliance.
Why?
Because:
-
Google can still access your messages
-
There is no legal encryption or audit trail for sensitive information
For fully compliant communication, look to use secure email providers or encryption plugins that include audit logs and complete data protection.
💭 Final Thoughts: Should You Use Gmail Confidential Mode
