12 Most Useful Gmail Add-ons and Extensions for 2023

Gmail is one of the most popular email clients in the world. It's used by millions of people for both personal and business purposes. Do you already enjoy the basic features of Gmail? Consider improving your productivity by using add-ons and extensions. 

In this post, we will help you understand what Gmail add-ons are and how they differ from Gmail extensions. You’ll also discover a list of the best Gmail add-ons and extensions to start using today.

Gmail Add-ons vs. Gmail Extensions

Gmail add-ons are small pieces of software that add extra features or functionality to Gmail. Use them to do things like track your emails or manage tasks. You'll only discover these add-ons inside the G-suite Marketplace.

While Gmail extensions are Gmail-specific browser extensions. They interact with Gmail when you’re using them with the Google Chrome browser. 

The difference

Add-ons work with the Gmail API and can do things like:

• Create new messages

• Modify existing messages

• Send messages without ever opening Gmail‍

To use an add-on, visit the G-suite Marketplace. Find your desired Gmail add-on, click to install it, and agree to the app's permissions.

Gmail extensions don’t have access to the Gmail API. To use a Gmail extension, you first need to visit the Chrome Web store. Find the Gmail extension you prefer. Tap on "Add to Chrome." Click on the confirmation popup. 

Typically, a Gmail add-on will perform tasks like helping you schedule emails to send them later or giving you ideas for the perfect subject line. Gmail extensions can make Gmail look better, work faster, or help you get through your inbox more productively. 

Other differences include: 

• You use Gmail add-ons on the web, on Android, and iOS

• You can only use Gmail extensions on the web
