How to Use Gmail to Send Encrypted and Confidential Emails

Gmail does not automatically protect emails. You must utilize Gmail’s Confidential Mode to make your emails more private when you send them, but this is not a full encryption service. If you have a regular Gmail account, you can use ‘confidential mode’ by Google. This makes sure your emails can’t be changed by anyone, and it’s good for personal accounts.

When you use Gmail for business or higher education, another security option known as S/MIME (Secure/Multipurpose Internet Mail Extensions) is available. S/MIME simply hides the contents of the email so that only the person with the right password can open it and read what’s within. This secures your email from unauthorized access.

If you have a paid Google Workspace account, you can enable ‘S/MIME.’ This works on Android phones, iOS apps, and the Gmail desktop app. It helps you send emails that are encrypted, meaning they are extra secure. In this post we have discussed how to send encrypted and confidential emails on Gmail.

Can I use Gmail to send an encrypted email?

  • You must activate the S/MIME option.
  • You may utilize S/MIME if you have a paid Google Workspace account.
  • To enable S/MIME for everyone who uses Google Workspace, you must log in to the admin panel.
  • The recipient of your secure email must have S/MIME enabled.

Why should I use S/MIME in Gmail?

S/MIME protects your email as it goes from sender to receiver. This means that your email will not be lost or corrupted while passing over the network. This provides that only the person who sends the email and the person who receives it may view the contents. It stops hackers, spam messages, and other fraudulent applications from reading the private message.

What are the benefits of Sending a Secure Email using Gmail?

  • Set an expiry date for email access.
  • You may disable email access at any moment.
  • To view an email delivered through email or SMS, you may need to enter a password.
  • Your email will not be able to be downloaded, forwarded, printed, or copied by the recipient.

Is Gmail’s confidential mode safe?

No, Gmail’s confidential mode may not be safe. It allows you to make emails expire and limits actions like copying or printing if there’s a problem. Also, these confidential mode emails are not encrypted from start to finish, so Google may still view them.
