Next, let’s dive into Gmail extensions.

What Is a Gmail Extension?

A Gmail extension is a tool that adds extra features to your Gmail account. However, it only works on your desktop’s Chrome browser and can’t be added to Chrome’s mobile app.

But how is a Gmail extension different from a Gmail add-on?

Both add-ons and extensions help you extend Gmail functionality.

But a Gmail extension is installed on your browser, while an add-on is installed on your Gmail account. As a result, if you log in to your Gmail account on a different desktop or browser, you’ll no longer have access to the extension’s functionalities.

You can install extensions from the Chrome Web Store.

Now, let’s look at some of the best Chrome extensions you can use to enhance Gmail’s functionality:

• Gmelius
• ActiveInbox
• Digify
• Mailstrom
