Best Gmail Add-ons and extensions for 2021

There are now more than a billion people using Gmail to manage daily work tasks. And for good reason — it’s an amazing tool. But even Gmail has its limits.

Sometimes, you probably wish there were functionalities included in the native Gmail app that just aren’t there. Those missing capabilities are something that can really slow you down and make work harder than it needs to be.

This is where Gmail add-ons and extensions come in. These are simple tools you can add on to your Gmail to extend its capabilities. There are literally thousands of them to choose from, with many big names you probably already know. But which ones are the best?

That’s the question we’ve set out to answer. At Amitree, we believe in making productivity tools that help you save time so you can get more done, looking like a pro without any extra effort.

We’ve narrowed down the list to the seven best Gmail add-ons and extensions to help you do just that. With these email tools, you’ll boost your productivity and work smarter, not harder.

What Gmail Add-Ons and Extensions Are and Why You Need Them

Add-ons and extensions are pretty common and you may already be using some of them. But if you’re new to Gmail tools, here’s a little background on what they are and why you need them.

Gmail add-ons and extensions are a kind of software tool that can work inside your Gmail app, giving it new functionality and capability. These app integrations save time and streamline your workflow because you don’t have to leave Gmail to use them.

You can use Gmail add-on and extension tools to do many different kinds of work, from sales and marketing to project management to collaboration.

You’ll hear these tools referred to with different terminology, such as add-ons, extensions or sometimes just as apps. The difference has to do with how they integrate into Gmail.

  • Gmail add-ons are tools that can add new layout options and functionality to your Gmail and other Google Workspace apps like Calendar and Drive. These G-Suite add-ons work on the server side and integrate directly with the apps. You can get Gmail add-ons via the Google Workspace Marketplace, which is easily accessible from inside any Google app.
  • Gmail extensions are very similar to add-ons and also add new layout options and functionality to your Gmail experience. While Gmail add-ons use backend integration, Gmail extensions are frontend and work inside your Chrome internet browser. You can get Gmail extensions from the Chrome Web Store, which is easily accessible on the web or from the Chrome menu.
  • Gmail apps are another term you may see used to describe Gmail add-ons and extensions. A Gmail app is any kind of third-party tool that works with Gmail to add new layout options or functionality. While some apps are found in the Google Workspace Marketplace or Chrome Web Store, others are standalone. This means that you can also use them outside of Gmail and Chrome with other apps and browsers.

Gmail add-ons, extensions and apps are very useful when it comes to boosting your email productivity, saving valuable time and growing your business and career.

The thing that makes all these add-ons and extensions so handy is that they become a part of your inbox. You don’t need to stop what you’re doing in the middle of an email session to make notes, schedule appointments, manage tasks or handle other work items.
