Working in a digitally-connected setting undoubtedly ties you to your email account.

You’re sending and receiving emails all throughout the day, and quite often, there’ll be a task attached.

As work has become increasingly more digital in nature, companies have developed email add-ons to make specific tasks simpler.

If you’re a Gmail user, you’ll know that Gmail has become an invaluable tool in recent years, in part because of its Gmail add ons and extensions for Google Workspace.

What Are Gmail Add-Ons?

Add-ons are third-party technologies and services that help make your Gmail inbox more functional.

You can access them all in the Google Chrome web store.

Gmail already has a few tools that function similarly to add-ons, including Calendar, Tasks, and Keep.

Although it isn’t technically an add-on, Calendar is a great example of how efficient an add-on can be.

Essentially, whenever you get an email invite from a coworker, you can choose to add it to your Google Calendar directly from the email.

Optional Gmail extensions and add-ons work much the same way, and many are available in the Gmail app.

However, their functions vary wildly and can help you accomplish nearly any task.

Why Use Gmail Add-Ons

Although there are many reasons to use Gmail add-ons and extensions, the two most common are increasing productivity and saving time.

Many Gmail add-ons can help you increase productivity by enhancing collaboration opportunities.

For example, Slack, Zoom, and other collaboration add-ons make working with your team from anywhere a breeze.

In addition to the collaboration features you can get with Gmail add-ons, there are many ways they’ll help you save time.

For example, add-ons like DropBox and Trello let you organize your workspace and files quickly and all in one place.

How To Add a Gmail Add On

Adding a Gmail add-on is pretty simple.

All you need is a Gmail account and access to the G Suite Marketplace.

  1. Log into your Gmail account.
  2. Find the sidebar on the right side of your Gmail homepage. There’ll be several icons running vertically down the page. These are native or installed add-ons.
  3. Click the “+” at the bottom of the sidebar icons.
  4. A window will pop up that displays all of the available add-ons for your account.
  5. Scroll through or use the search bar to find the add-on you’re looking for.
  6. Click “Install” and follow the prompts on the screen.

Note: You may need to exit and restart your browser for the add-ons to function.

How To Remove a Gmail Add On

You can easily remove any Gmail add-ons you’ve installed in just a few quick steps.

1. Open Gmail.

2. Locate the gear icon at the top of the page.

This is where your settings are.

3. Click the gear, then choose “See All Settings.”

4. Navigate to the Add Ons tab.

5. Click “Manage” under “Installed add-ons.”

6. Find the add-on you want to remove and click the three dots.

7. Select “Remove” to remove the add-on.

As with installing add-ons, you might need to restart your browser for the change to take effect.

With so many Gmail add-ons and extensions to choose from, it can be tough to narrow down the best choices.
