Ray Tomlinson invented the email in 1971 to make communication faster and save time.

And today, an average worker spends around five hours per day lurking in the inbox.

Why the tool that was developed to save time is now a tool for procrastination?

The answer is simple: disorganization.

A professional gets around one hundred twenty-one business emails on an average day. This means a backlog of unopened emails.

Undoubtedly, Gmail is one of the best email service providers because of its simplicity, robustness, and price (free for most).  It’s already been used by more than 1.5 billion people per month.

It’s an excellent tool to send, receive, and manage emails, be it for business or personal usage.

But with a simple Gmail, there are some limitations to skyrocketing one’s productivity.

Tip - Do you want to save time and be more productive?

Here’s a list of the top productivity apps you should be using.

It turns out there is a solution to boost efficiency while using Gmail. And you don’t need to install any resource-hogging software for it.

Enter Gmail Add-Ons and Extensions

There are two ways to improve productivity while using Gmail. Either use Gmail add-ons or Gmail extensions. The two differ in the way they are integrated.

What are Gmail Add-ons?

Gmail Add-ons are tools that can be integrated directly into the Gmail app. These are created to extend the functionality of Gmail by providing additional features to the users, e.g., enhanced security or note-taking.

Remember, they are available only on the G-suite Marketplace.

How to use Gmail Add-ons:

  1. Go to G-suite Marketplace and search for the desired add-on for gmail.
  2. Click on the add-on, and you’ll be directed to the app page.
  3. Now click install add-on and confirm account credentials.
  4. Finally, give permissions to add-on.

What are Gmail Extensions?

Gmail extensions are the tools (or extensions) that bring extra features to the Gmail dashboard/ app. These are installed as a Chrome extension. You can install them from the Chrome Web store instead of the G-suite Marketplace.

How to use Gmail Extension:

  1. Open the Chrome Web Store and search for the preferred Gmail extension.
  2. Tap on Add to Chrome.
  3. Confirm Add Extension.

The whole process of installing Gmail add-ons and extensions requires just a few clicks. Let’s look at the top Gmail Add-ons and Extensions to increase productivity and save crucial time.
