The 10 Best Gmail Extensions

Keepng Team | August 30th, 2021

Gmail is one of the most popular business email providers. In fact, it’s been reported that more than 60% of mid-sized businesses and 92% of startups use Gmail. There are many reasons why so many businesses choose Gmail. Not only is it affordable, but it’s also easy to use, reliable, and secure. 

Even though Gmail is an effective, powerful tool, there’s still a lot that it can’t do. Fortunately, there are countless Gmail extensions available for download that can make up for what Gmail lacks.

A Gmail extension is a Google Chrome extension that can improve the look or functionality of your Gmail account and inbox. There are thousands of Chrome extensions, so it’s important to know which ones you should download to improve your business email experience. Here’s a look at the 10 best Gmail extensions.


If your team uses a shared inbox to respond to customer support requests, you can benefit from the Keeping Gmail extension. Keeping turns Gmail into a customer support tool and help desk. You can use Keeping to:

  • Turn emails into help desk tickets that can be assigned to members of your team.
  • Add notes to emails to provide your team with more information on specific customer issues.
  • Avoid duplicating efforts. Keeping will tell you when someone else has already responded to an email or is in the process of responding to it, so you won’t waste your time working on the same customer request.
  • Pull reports that show how well your team is responding to customer support requests.

Now, you can provide high quality customer service without ever leaving your Gmail inbox.

Sending an email with spelling and grammar errors can make you look unprofessional. Gmail has a built-in spell checker, but it is not designed to catch certain errors, including grammar mistakes and misused words. The Grammarly Gmail extension, however, can catch everything that Gmail misses and more.

As you type an email, the Grammarly extension will review it to look for spelling or grammar errors. If an error is detected, the Grammarly extension will immediately notify you and suggest ways to correct it.

This tool does more than just check your writing for spelling and grammar errors, though. It also reviews what you are writing in real time to make sure you are communicating clearly and concisely. It acts as your personal writing assistant to help you improve your communication skills one email at a time.


If you’ve ever wanted to learn more about someone you are communicating with via email, Discoverly is the right Gmail extension for you. 

Every time you receive an email from one of your contacts, the Discoverly extension will automatically search for the contact on Facebook, Twitter, and LinkedIn. Then, the contact’s social media profiles will be displayed right in your Gmail inbox. You will be able to instantly see each of your contact’s tweets, Facebook posts, and connections you may share on LinkedIn. 

This extension provides you with the information you need to learn more about the people you are emailing so you can establish deeper, more meaningful connections with your contacts. For this reason, it is ideal for people who work in sales, public relations, recruiting, or other fields that rely on building strong relationships with contacts.

Just Not Sorry

When communicating via email, your word choice could impact how you are perceived. Just Not Sorry is a Gmail extension that is designed to help you avoid using words or phrases that could potentially undermine what you are trying to say.

As you type an email, Just Not Sorry will underline any words or phrases that may diminish your voice. You can hover over the underlined words or phrases to learn more about the potential impact of your word choice and why you should consider changing it.

Just Not Sorry may encourage you to remove or change commonly used phrases such as:

  • I’m sorry
  • I think
  • I’m no expert, but…
  • I’m just writing to say…

With Just Not Sorry’s help, you can learn how to clearly get your point across and write more powerful, persuasive emails.

Zoom for Gmail

If you frequently attend video conferences via Zoom, you may want to download the Zoom for Gmail extension. This extension allows you to access all of Zoom’s features without leaving Gmail.

Using this extension, you can start or schedule a Zoom video call with an email contact with just a few clicks of the mouse. The extension also gives you access to your Zoom calendar directly through Gmail. This means you will be able to see what Zoom meetings you have scheduled in the hours or days ahead without opening a new window or closing your inbox.

This extension helps you centralize your communications so you don’t need to switch back and forth between different programs or tools to connect with your contacts. It also works across desktop and mobile devices, so you can access these features regardless of whether you are on a computer or smartphone.

Slack for Gmail

Like Zoom for Gmail, Slack for Gmail is an extension that gives you access to the tools you need to communicate directly through your inbox.

Once the Slack for Gmail extension is installed, you can forward any of your emails to specific channels or people in Slack. The email will only be visible to the people you choose to share it with in Slack. 

You can include a message when forwarding an email to Slack to provide your contacts with more information. You can even include the attachments from the email so your Slack contacts will have access to everything. 

You can use this extension to collaborate with your team on an email response. For example, if you aren’t sure how to respond to a question from your manager, send it to your co-workers in Slack and ask for their input.

DocuSign for Gmail

If you are in a position that requires you to sign a lot of paperwork, the DocuSign for Gmail extension can help. Once you install this extension, you will be able to review and sign documents the moment they arrive in your inbox. You won’t need to open a new window or program to access these documents, either. Everything will take place right inside your Gmail inbox.

If you are sending paperwork to someone else for approval, you can use this extension to upload the document into Gmail, tag the locations where their signature is needed, and email it to them for their review.

You can also use DocuSign for Gmail to quickly send email reminders to people who still need to sign documents.

All of your data is encrypted, so you won’t need to worry about keeping your information secure when using DocuSign for Gmail.

Inbox When Ready

It can be hard to focus on your work when you are receiving an endless stream of emails. Each notification that pops up may serve as a distraction and make you feel more overwhelmed, which could affect the quality of your work. If you need help focusing, download the Inbox When Ready extension for Gmail.

Decide how many times per day you want to check your inbox. Then, check in using the extension’s reporting feature to see how close you are to reaching your goal.

You can also use this extension to schedule an “inbox lockout.” During your inbox lockout, your inbox will be temporarily frozen, which means you won’t see any new emails that come in during this time. Once the lockout is over, your emails will appear in your inbox so you can address them at a time that is most convenient to you.


You may want to install the Digify Gmail extension if you frequently send sensitive or confidential data via email. This extension allows you to send attachments via email that automatically delete themselves after a certain amount of time. You also have the option of controlling whether your contacts are allowed to print the attachments you send. Both of these features protect your data by limiting the amount of time that your contacts can access it. 

You can also use this Gmail extension to monitor who has opened your attachments and how many times each attachment has been opened. If you accidentally send an attachment to the wrong contact, you can use Digify’s “unsend” feature to prevent your sensitive data from falling into the wrong hands.

You may benefit from the Murmure Gmail extension if you frequently BCC or CC people on your emails. You can use this extension to attach a private message to any contact who is BCCed or CCed on an email. This way, you won’t need to send a separate email to your BCCed or CCed contact to provide context for a previous email. The private message will not be visible to anyone who isn’t BCCed or CCed on the email.

For example, if a customer emails you asking for a refund, you can respond to their email and CC the person who is responsible for issuing the refund. Then, attach a private message that provides the person with the information they need to issue the refund. This is just one example of how this feature could make managing your emails easier. If you need a more robust solution, Keeping allows you to have a full chat conversation on any email support ticket.

If you haven’t already, check out how these gmail extensions can significantly improve your productivity! And remember, Keeping is the fastest way to share your customer support mailbox with your entire team.
