Gmail extensions are tools that add extra functions to your Gmail page, allowing you to customize Gmail to suit your preferences. If you want to enhance your Gmail experience with additional features, then using Gmail extensions is a good idea.
However, if you don’t need any extra functionality on your Gmail, you can easily do without these extensions.

Gmail extensions are tools built to improve functionality and add more features to your Gmail web app. While there are several extensions for Gmail, below is the round-up of the best ones I’ve come across based on the functions they offer, ease of use, and how users accept them:
SNo. | Extension Name | What it can do |

ChatGPT for Gmail
In the world of jaw-dropping AI innovation, currently, the most useful and practical use of AI is using it as a personal AI writing assistant. And since the majority of the communication in email is text, AI can be very useful to help you write faster and summarise your emails better.
This is where AI email clients are available for Gmail, out of which ChatGPT for Gmail has remained my favorite because it’s free and offers unlimited custom prompts without any hard limits, unlike other tools. Plus, you also don’t need to switch between tabs.
You can directly use that extension inside your Gmail tab. You can generate subject lines, rewrite them for better clarity, rewrite the complete email content, and even regenerate it at once. You can also custom reply to emails directly from the same interface without copy-pasting text between tabs.

Email Tracker by Mailtrack
Having a built-in email tracker can help you know when someone opened your email, especially in situations like business deals, job applications, and email follow-ups. However, despite being the primary email communication platform for the majority of users, Gmail still doesn’t have a native email tracker for your email communications. Fortunately, there are plenty of third-party extensions that offer this functionality for Gmail for free.
There are plenty of email track extensions available for Gmail but Mailtrack has remained my favorite because of two reasons, first the free version allows you to track individual emails with real-time link alerts and can also track recipients individually in group calls, and next it is also available for the iOS and Android as a mobile addon (for Google Workspace users) which can help them to track the emails on the mobiles too.
It is also GDPR-compliant and ISO certified, which you can use to track your emails, thus reducing your anxiety. The extension is free to use; you can download and start using it inside your Gmail for free.

InboxPurge
As the name implies, InboxPurge is a tool designed to clean your Gmail inbox of unwanted emails and effortlessly mass unsubscribe from newsletters or subscriptions you may have intentionally or unintentionally signed up for.

While using the software, it scans your email subscriptions and lets you unsubscribe from redundant ones all at once, with the option to delete their emails as well. Additionally, it allows you to bulk delete emails from any newsletter subscription without unsubscribing.
Furthermore, InboxPurge enables you to access and undo any mistakenly blocked email addresses. Another useful feature is the ability to organize your newsletters into an easy-to-read digest. Overall, this Gmail extension is very straightforward to use.

FlowCrypt
While Gmail is encrypted in transit, but still Google and others can still technically have access to your email and its contents. If you often share sensitive or confidential information in Gmail, such as legal documents, contacts, or even sensitive personal inquiries, encrypt your email so that you can make sure only the intended recipient can read it instead of a middleman.
Services like ProtonMail and Tutanota offer built-in encryption. Since you are using Gmail, you can get the same encryption standard using a free Google Chrome extension. FlowCrypt is one such tool that allows you to send encrypted emails directly from Gmail. Plus, along with the message content, all your attachments, including PDFs and images, can also be encrypted.
Even if the recipient doesn’t use FlowCrypt, you can send a password-protected message. In addition to these, FlowCrypt also has a dedicated mobile app for both iOS and Android, which can help send and access encrypted messages on these platforms too.
Todoist for Gmail
Often, tasks are sent to us via Gmail, whether assigned by others or self-assigned, and it’s easy to lose track of them among the many emails we receive. Todoist simplifies this by allowing you to track and manage tasks directly from your emails.

With a single click, you can convert an email into a task and add details like due dates, priority, and reminders (for paid users). This helps you keep your email to-do list organized and ensures you stay on top of your tasks.

Checker Plus for Gmail
Checker Plus for Gmail is an extension that enhances your Gmail experience with additional functions. It offers a new, unique Gmail interface with expanded editing capabilities, such as different fonts, text alignment options, and more.

You can also customize Gmail with themes and skins to suit your preferences and even have emails read out loud. What this tool essentially does is that it allows you to access your Gmail emails without opening the Gmail page, while also providing extra features.
This extension supports offline email access and desktop email notifications, making it a valuable addition to your Gmail toolkit.
Simplify Gmail
Simplify Gmail is another extension that allows you to customize your Chrome-based Gmail interface and user experience. It streamlines the Gmail interface, helping you focus on the essentials while enhancing the UI’s aesthetics.

With this tool, you can enable dark mode at any time, change fonts and menu arrangements, customize the browser tab, bundle emails by label, group emails by date, and much more.
It’s one of the must-have Gmail extensions, as it lets you create a completely new look for Gmail while simplifying your email management.

ActiveInbox
ActiveInbox is a third-party extension for Gmail that offers a range of features to enhance your email management experience. This tool allows you to turn emails into tasks, customize them by adding notes, and organize them into folders.

You can convert all your Gmail emails into daily to-do lists by adding due dates, enabling you to track them based on these dates.
Additionally, ActiveInbox lets you track email replies by setting a reply due date. If no reply is received by the due date, the email will automatically appear in your to-do list, providing a more efficient way to manage emails that have yet to be responded to.
Get ActiveInbox
Boomerang for Gmail
Boomerang is a Chrome extension for Gmail that enhances the Gmail Compose window with several handy features. It allows users to schedule emails for later, set up recurring emails, and track responses effectively.

One feature I found very useful on this tool is the read receipt, which notifies you when emails are read or links are clicked.
Additionally, Boomerang simplifies meeting scheduling directly from your inbox and offers the option to temporarily pause incoming emails, such as over the weekend, with an automated response. Overall, Boomerang is a valuable tool for anyone using Gmail on Chrome.

Sortd for Gmail
Sortd is another excellent Gmail extension designed to help you organize task-related emails and boost your productivity. It allows you to create boards like Trello, where you can sort emails as tasks using drag-and-drop functionality.

Additionally, you can add details such as due dates, priority levels, reminders, and more to any task. Moreover, you can share the board with others to collaborate. It’s a powerful tool that transforms email management into a more efficient task management system.
