Gmail is a favorite email client for many people. Released by Google in April 2004, Gmail is used by 1.5 billion active users (as of 2019) – but even Gmail can use a boost every now and then. That’s why Gmail offers extensions and add-ons to help you extend the capabilities of Gmail to make it suit your workflows better and improve your productivity. 

The best thing about Gmail extensions and add-ons is that many are free. Not all of them are produced by Google either – many of them are from partners of Gmail, and there is a vast variety of functionality to choose from. From to-do list add-ons to Kanban boards, Gmail has even more potential to help you in your work, with add-ons even from such popular giants as Slack or Zoom. 

And remember, even after you have installed an add-on or extension, you can always remove it. The possibilities for Gmail are limited only by your imagination when you take advantage of these add-ons or extensions, often for very little or low cost. 

If you didn’t know about Gmail add-ons, it’s time to explore the options that are available.

What is a Gmail add-on?

A Gmail add-on is an app that can be installed directly into Gmail, found through the Google Workspace Marketplace. Many apps are paid, but a significant number also offer free tiers, widening their access to more of the public. 

Add-ons enable you to keep using Gmail while using extended functionality that Gmail does not currently offer, such as replying to more than one email with the same message. There have of course, been some functions that Gmail previously did not support, such as the ability to schedule an email, which was only possible with add-ons. Gmail now offers the ability to schedule an email. 

As we have already mentioned, an add-on may or may not have been developed by Google, but Google has to approve it in order for it to be available in the Marketplace. While Google verifies add-ons, they have not been subject to the same security checks as standard Google apps, so you should be careful when installing add-ons. Stick to trusted and popular add-ons just to be safe. 

So, a Gmail add-on is simply a way to install extra features on Gmail to help you get more done. 

What is the advantage of a Gmail add-on?

If you use a Gmail add-on, you can continue using Gmail in the same way whilst making it more powerful. Many people have been using Gmail for years and they want to have integrations with external apps without leaving their favorite email client. 

The great thing about Gmail is that it has a free plan, making it a fairly low barrier to entry for the majority of users. Increasingly, organizations are adopting Google Workspace for Business and Enterprise, so Gmail has steadily permeated the working world as a rival for Outlook. Gmail has an incredibly simple user interface, and its add-ons are no exception to this trend. 

You can save time with Gmail add-ons by integrating your favorite apps, meaning you don’t have to leave the Gmail interface to complete a task. Apps can work more seamlessly together when you utilize the power of add-ons. 

Gmail add-ons enable you to customize Gmail in your own way, and the great thing about Gmail is it’s a trusted Google app, so it attracts many app partners. 

How do I get add-ons for Gmail?

You find your Gmail add-ons in the Google Workspace Marketplace. To open up the Marketplace, click the plus icon on the right-hand side of your Gmail inbox. When the window opens, you search for the Gmail add-on you would like to install or select directly from the list of options presented. 

One thing to note is that you must ensure your search is filtered only to include add-ons for Gmail so that your search is narrowed down to Gmail-specific add-ons. Once you’ve found your desired add-on, click the add-on in the Marketplace to take you to the page where you can find out more and download it. Click “Install” to start installing your add-on. 

If you install an add-on and decide you don’t like it, you can always remove it by visiting the settings page. 

Difference between Gmail add-ons and extensions

The difference between a Gmail add-on and a Gmail extension is that the former directly integrates with the Gmail app in the back end. An extension, in contrast, affects Gmail’s performance in the browser. 

The primary way the user will perceive the difference between add-ons and extensions is the place they access the tool. Add-ons can be found in Google Workspace Marketplace, while the Chrome Web Store is a repository for Gmail extensions if you use Google Chrome. The way you install extensions will differ depending on which browser you are using. 

Of course, if you switch to a different browser for Gmail, then Gmail will no longer have the extensions installed. Add-ons, in contrast, are linked directly to your Gmail account.

Anyone working in a modern organization will probably be familiar with Slack. It’s a powerful internal communication tool that lets you send messages, discuss in threads, and hold virtual meetings. 

With the Slack Add-On for Gmail™, you can connect Gmail with Slack to easily send emails over to Slack when your inbox is getting too noisy. This saves you time in manually copying and pasting emails, as well as allowing you to directly send your email to a person or channel within Slack, while also including your own message and attachments if you wish. 

If someone is having a conversation about a customer within Gmail, this discussion may be more appropriate for Slack where more members of your team can dive into help. Slack is arguably superior to Gmail when it comes to group discussions so this approach can help your productivity. 

If you’re a fan of Slack, you’ll definitely want to install Slack Add-On for Gmail™.
