Like Zoom for Gmail, Slack for Gmail also helps you keep all your communications in one place.

14. DocuSign for Gmail

18. Giphy for Gmail

Chrome Web Store Rating: 3.9 (129 ratings)

Over the past few years, communication has become more and more expressive. With emojis, bitmojis, animojis, and good old gifs, there are tons of ways to express yourself nonverbally, even over text-based communication methods.

20. Digify for Gmail

You can think of Digify as the professional’s version of Snapchat: it allows you to send attachments that delete themselves after a set period of time. Additionally, you can view who’s opened your attachments, and you can even unsend attachments that were sent to the wrong person.

If you’re sending sensitive or private information over email, this extension is essential. Now, even if you send confidential information to the wrong person, you can save yourself by un-sending it.

• Add dynamic watermarks with the recipient’s email address for additional protection.

21. FlowCrypt Gmail Encryption

With so much of our lives online, cybersecurity is more important than ever. While Gmail has encryption features of its own, some people want to up the ante and send emails that are secured to a higher degree.

FlowCrypt helps you do just this. This extension uses PGP encryption to encrypt and secure all the emails that you send. If you often send sensitive or confidential information, this one is a great addition to your Gmail toolbox.

22. Evernote for Gmail

Evernote is an extremely popular note-taking platform, and Evernote for Gmail makes keeping a log of important information a cinch. This extension allows you to save important emails to Evernote from directly within Gmail. If you only need to save a few paragraphs, you can save partial emails as well.

If you’re already using Evernote, this is a great way to make sure you keep a record of all your most important emails handy.

23. KeyRocket

Keyboard shortcuts can improve the speed and efficiency with which you use an application. But even though Gmail is one of the most used applications in the world, a surprisingly small number of people use its shortcuts.

KeyRocket is here to change that. This clever extension helps you learn all of Gmail’s keyboard shortcuts, so you can become faster and more efficient with your emails.

24. Sortd for Gmail

Sortd works a lot like project management applications (Trello, Asana, etc.), but it’s designed to help you sort through and manage your email tasks specifically.

With Sortd, you can sort your emails into different columns based on priority, type of task, or any other criteria you can think of. This can help you organize your work and make sure you don’t let any important emails slip through the cracks.

25. PixelBlock

Privacy online is hard to come by these days. Even in Gmail, senders are constantly using extensions that track whether or not you’ve opened their emails. In other communication platforms, like iMessage, you can turn off read receipts, but in Gmail, if the sender is using a tracking tool, you’ve got no choice in the matter.

While PixelBlock doesn’t prevent an email sender from being notified, it does let you know whether you’re being tracked. At the very least, this can help you make more strategic decisions about when you do and don’t respond to emails — and it particularly prevents you from saying you didn’t see an email until just now when the tracker shows you saw it two weeks ago!

26. Clearbit Connect 

It’s common these days to receive emails from unknown persons. But don’t you want to know who’s behind that email?

That’s what ClearBit connect is built for. Searching through its massive database of data, it can display any valuable information of anonymous senders without leaving your inbox. These include email address, sender’s company, job title, physical location, and more.

To use the tool, first, download it from the Chrome web store and install it. Anytime you open a message, tap the clearbit icon on the sidebar to identify the sender.

27. Calendly for Gmail

Thanks to Covid-19, Calendly became popular since everyone was scheduling meetings.

And this gave the developers room to strengthen the tool by adding a Gmail extension feature. This means that you can now access all your event types and share the links to your calendly event through Gmail.

What’s interesting is that you can quickly set one-off meetings on the fly when reading your emails.

And thanks to this automation, it’s now easier to connect with your business and personal calendar, which saves you time by simplifying tasks.

28. Bookipi

Bookipi is a Gmail Extension that helps you keep track of your finances and invoices. It’s an excellent option for freelancers and small business owners because you’ll have your financial information in one place.

Bookipi is one of those add-ons that can make managing finances so much easier. It allows you to create invoices, estimates and even keeps track of your clients’ satisfaction ratings. It also has links to PayPal and Stripe, making it easy to get paid for your hard work.

30. LastPass: Free Password Manager

LastPass is a password manager that stores all your passwords and other account details in one secure vault.

It’s as simple as using Gmail to send an email – you log in to the site, type in your login details, and your data will be accessible – no need to remember complex passwords for all your accounts.’

It also has several cool features like secure notes (only you can access ) and password notifications. So you’re always aware when there are password changes on an account.

31. Gmelius

Gmelius is often known as a swiss army knife when it comes to Gmail extensions. It can do mostly anything you would need for standard Gmail tasks.

The primary features of Gmelius include things like email templates, email tracking, email automation, and even a shared inbox. This is especially helpful when you need to write custom emails to various recipients from various senders.

Sometimes, you simply don’t have time to track down multiple versions of an email and integrate it from another app. So as far as that goes, Gmelius is a contender for an all-in-one solution.

Just keep in mind that it will cost you $9 / month.

32. Boomerang

One of the Gmail extensions that you might have already heard of is Boomerang. This classic app is one of the original Gmail apps.

Primarily, Boomerang focuses on being an outreach productivity extension. One of the newer email features that it has added, however, includes AI writing. The AI can help you identify better ways of communicating and even find typos in your emails.

Other main features include things like Mass Email and Templates. You can get a plan for as low as $5 / month.

33. Wrike

When it comes to project management software that you can attach to Gmail, Wrike is up there with the best. It helps you create tasks and even view them and edit them — right from within Gmail itself.

In addition, you have features like send and receive comments that also don’t require you to leave Gmail. Oftentimes, it can be difficult to manage multiple people and collaborations when working within Gmail.

Thanks to Wrike’s forethought, you can collaborate, share access, change visibility, and otherwise manage your projects totally remotely in a way that gives every participant what they need to move it along.

34. TeamCal

Have you ever wished that there was an easier way to sync calendar functions with Gmail? Well, that’s exactly what this Gmail extension does for you.

When you use TeamCal, it’s easier to plan and schedule team functions, events, meetings, and projects.

This is a particularly useful app for those in management. You’ll often have multiple people and projects to juggle at any given time.

But with TeamCal, you get useful features like Google Calendar syncing, phone syncing, sharing, printing, and event invitation management. That way, you can take the pressure off yourself and put it on the extension.

35. Gfycat

In modern email etiquette, there’s nothing more important than GIFs. Joking aside, GIFs have truly become more popular and acceptable in communication ranging from text messages all the way to professional emails.

However, up until now it was a little confusing and difficult to find the right GIF and send it via email.

Luckily, Gfycat is a useful extension for Gmail that solves this problem. You can easily find the perfect GIF in comments from a selection of over 40 million of them. And the best part is, you can then insert them right into your email without ever leaving Gmail.

Bonus Tool: Contact Out

ContactOut is a Chrome extension that gives you the ability to quickly find the email addresses and other contact details of your leads right on their LinkedIn or Github profiles. This powerful tool taps into a database of over 1 billion triple verified email addresses, delivering contact details with high volume and accuracy.

This tool also comes with a dashboard that allows you to organize your leads and export your list to your device, and a people search portal that you can use to find prospects in any industry that are not on LinkedIn. It can also integrate with Greenhouse and Salesforce.

Conclusion

But don’t get carried away. Too many extensions can slow your browser down, and some don’t play nicely with each other. Keeping it simple is critical. Choose your extensions wisely and ditch any that you aren’t using on a day-to-day basis.

Work smarter – not harder – as we move into 2024.
