22 Gmail Add-Ons & Extensions to Enhance Email Productivity

The average U.S. worker spends 28% of their workweek reading and responding to and sending emails. If you’re anything like the average worker, you spend over 10 hours a week looking at your email inbox. And not all of this time is directly productive as a fair chunk of it is probably spent trying to make sense of what tasks to prioritize.

As Gmail is a powerful tool, there are plenty of ways to improve your email productivity and reduce that time.

In this post, we’ll take a closer look at the best Gmail add-ons and Gmail extensions that can help you reach this goal.

Ready? Let’s get started!

Google Workspace Marketplace vs Chrome Web Store

Before diving into the actual list, let’s explain the terminology first.

There are two places through which you can extend the functionality of Gmail: the Google Workspace Marketplace and the Chrome Web Store.

The Google Workspace Marketplace offers add-ons that directly integrate with Google Workspace apps on the backend. They integrate with the server-side app for example Docs (which you can even import to WordPress), Sheets or Gmail. Here is where you’ll find Gmail add-ons.

The Chrome Web Store, on the other hand, offers extensions that extend the functionality of your Google Chrome web browser. From ad blockers, to-do lists, to Gmail-related tools and apps. Here you’ll find, among others, Gmail extensions.

What Is A Gmail Extension?

A Gmail extension is a Google Chrome extension that directly impacts the layout/function of your Gmail dashboard/account. You can find many of the available extensions in the Chrome web store as you just saw.

Others are only available through the website of the company that creates the app.

How Do I Add a Gmail Extension?

Adding a Gmail extension is as simple as finding the extension you want in the web store and clicking the “Add to Chrome” button.

And then confirm it by clicking the “Add extension” button when prompted.

You’ve now successfully added a Gmail focused extension to your Chrome browser. You should be able to see it show up in the top right of your toolbar.

How Do I Remove a Gmail Extension?

You manage all your Gmail related Chrome Extensions in the same interface you administer all extensions: in the extensions dashboard.

Type in “chrome://extensions/” in the URL bar and press enter or open the menu, hover “More tools” and select “Extensions”.

From here, all you have to do is click “Remove”, and you can remove any extensions you no longer need.

Are Gmail Extensions Safe?

Since Google doesn’t publish all Chrome extensions, they don’t claim responsibility or ownership of any security issues. Since they are third-party applications, any risks that might be present are on you.

That doesn’t mean that all extensions are unsafe, but it means that you should use some discretion when installing one. After a backdoor scandal in 2018, Google decided to up its game and put stricter demands on its extension developers.

For example, extensions can no longer demand access to unrelated personal data. Typically you don’t want to be the first one to try a new extension. Look for established extensions with positive real, human feedback. Look for extensions posted by legitimate companies or developers with a public presence.

If someone is unwilling to claim ownership of an extension, they might be worried about future repercussions.

What Are Gmail Add-Ons?

Gmail add-ons are similar to extensions in that they are created to extend the functionality of Gmail. The difference between an extension and an add-on is that the add-on is installed into your Google Workspace app, not the browser.

Remember: add-ons can be found in the Google Workspace Marketplace.

How Do I Add a Gmail Add-On?

To add a Gmail add-on, go to the Google Workspace Marketplace and click the one you want to install. It will take you to that particular app’s page.

From here, all you need to do is click install. Then confirm it, and verify your Google account credentials.

Finally, click the “Allow” button.

Simple right? With just a few clicks and one login, you were able to add extra functionality to your inbox.

How Can I Remove a Gmail Add-On?

You can manage all your Google Workspace add-ons, hence your Gmail add-on, from the “Manage Apps” section of the Google Workspace Marketplace.

To remove one, hover the menu button and then select “Uninstall.”

This time it’s a single click. Not a very complicated process to say the least.

Now that we know all the ins and outs around Gmail add-ons and extensions, let’s have a look at what we think are the most powerful ones!
