Outline:
Among all the tools I tested, I’ve compiled my top list of 5 Gmail add-ons for various purposes. Click on each solution for its more detailed description.
| Category | Add-on | Why is it the best one? |
|---|---|---|

Read on to explore other add-ons from each category I’ve tested and make up your own list of top Gmail tools.
First things first: why should you trust my choice? Well, I wanted to suggest only practical and efficient software, so I personally tested each tool. During this experiment, I focused on the following:
I cross-checked G2, Capterra, Chrome Store ratings, and Chrome-Stats reviews to discover which tools are most popular with the sales and marketing community. I also turned to Reddit and Facebook channels that discuss business technology to discover Gmail extensions 2025 usage trends.
I wanted to prepare a list of top Gmail productivity tools that actually save time in daily use. So I tried to execute as many different workflows as possible with each extension. Then I compared the time I spent completing similar tasks with different software.
I also noted the time it took me to install the tool and get the hang of it. Software’s usability and interface were important during evaluation, too. After all, no one would love to strain their eyes every day to get through a complicated interface.
Not everyone uses a designated mailing client. Some professionals prefer to open their mailboxes directly from the browser. So I checked how Gmail extensions popular in 2025 behave in different browsers, how they combine with each other, and how they integrate with a Google Workspace ecosystem.
Additionally, I considered how easy it would be for a sales or marketing team to use particular tools. Does it allow team access? Do users need to pay for additional members? Which team functionality is available? These were the questions I entered the experiment with.
Budgets are tighter this year, so the top Gmail tools for small teams shouldn’t be too expensive. Even better if they have a free tier or at least a trial plan to fully explore the tool’s functionality before committing to it.
Whether you’re a marketing or sales professional, a recruiter, or a business owner, you’re probably juggling multiple workflows throughout the day. That’s why I tried to explore solutions that cover a variety of everyday routines: email tracking, outreach, productivity, contact management, meeting scheduling, etc.
With all of these criteria in mind, I started digging through available Gmail extensions. Here’s what I found.
For many sales professionals, recruiters, or business owners, email is the primary lead generation channel. Without proper tracking, you don’t know if recipients are reading your emails, which makes outreach a guessing game.
❗️Please note: According to our team’s research, tracking email opens can reduce your reply rate by half.
That’s why I highly recommend tracking link clicks instead to monitor your outreach performance.
Best for: Sales reps, recruiters, and SMB owners who need reliable tracking without limits.
Chrome Store rating ⭐: 4.9/5
Price: free
Schedule email sending, track your campaign performance, and receive follow-up reminders right inside your mailbox with this Gmail email tracker extension for Chrome. This add-on is absolutely free and secure.
Tracked emails don’t include any signatures, labels, or logos, so recipients never know about tracking. A user, on the other hand, gets instant push notifications when someone opens or clicks a message. More so, this tool always sends useful reminders regarding campaign engagement.
Key features of Snov.io Gmail email tracker:
✅ Pros:
This extension is truly free and unlimited – no hidden charges, no ads or logos. It’s also fast in operation, with a highly intuitive interface, which makes it the top Gmail tool for everyday use.
What if a user’s inbox can become their outreach hub, complete with engagement tracking? With this idea in mind, we’ve created a free Email Tracker for Gmail – helping our users stay organized and never miss out on an opportunity.
Head of Product Marketing at Snov.io
❌ Cons:
The reporting is not very sophisticated, so if you want a deeper analysis, you need to send your campaign from the Snov.io app.
User reviews:
Customers give Snov.io Email Tracker high acclaim.
My experience with this extension:
The best Gmail add-on for email outreach. It’s not sophisticated, but functionality works fine. Tracking is reliable across all sent emails, open alerts are instant, and reminders pop up on time. I haven’t encountered any challenges during installation or usage.
Best for: Individual users as well as teams that want to send high-volume, personalized outreach campaigns from the comfort of their inbox
Chrome Store rating ⭐: 4.8/5
Price: from $25/month
Gmass can turn your mailbox into an email marketing workstation. It allows sending personalized bulk campaigns, automating follow-ups, scheduling sends, managing replies, and optimizing deliverability.
Key features of GMass:
✅ Pros:
This Gmail email tracker add-on integrates seamlessly with Gmail and Google Workspace, including Sheets. The tool also offers automation features for streamlining email campaigns. Plus, it can safeguard your senders’ reputation and deliverability.
❌ Cons:
Some users report that it slows down their mail client during large campaigns. Its interface feels somewhat clunky compared to simpler tools. Also, it offers only a short 7-day free trial with only 50 send-outs available per day.
My experience with this add-on:
This extension is listed among the top Gmail tools for a reason. It worked smoothly for me; besides, I found the analytics accurate. However, I wouldn’t buy it for daily use since I can achieve the same functionality for free with other tools (e.g., Snov.io’s Cold Outreach Tool).
Best for: Users who exchange documentation via email
Chrome Store rating⭐: 4.4/5
Price: Fee plan; paid subscription is $5.99/month
Discover who opened your email and attached .pdf documents in real-time using a free version of Mailtrack. When upgrading to the paid subscription, you can track link clicks, view campaign reports, or integrate contacts with CRM software.
Key features of Mailtrack:
✅ Pros:
This Gmail email tracker has a clean, intuitive interface; it is easy to set up and use. The add-on offers numerous features for tracking document access, as well as adding videos, GIFs, and other media to your emails.
❌ Cons:
The free version is rather limited – it tracks opens, but not link clicks, which may lead to skewed analytics. The sending capacity is only 100 emails on a free plan compared to 60k on a paid tier. Additional software integrations are also a paid feature, which means I couldn’t even test their functionality.
User reviews:
Mailtrack has got lots of negative reviews, which, personally, for me, are a red flag.
My experience with this add-on:
Although I encountered no major issues with Mailtrack’s usage, a couple of my test emails landed in the Promotions folder. Besides, the free version’s capabilities don’t allow link tracking, which is an important task for marketers. Plus, recently, the tool has removed the option of tracking how many times the email has been opened – a discouraging update indeed.
Best for: Sales teams that need a sales enablement suite implemented in their Gmail
Chrome Store rating ⭐: 4.2/5
Price: from $19/month
The Yesware Gmail email tracker allows you to monitor your outreach campaign’s performance right from your mailbox. Its paid plans offer a full array of email marketing and sales enablement tools – from open tracking to integrations with Zoom, Teams, and phone meetings.
Key features of Yesware:
✅ Pros:
This tool offers open, click, attachment tracking, as well as activity history. It integrates well with CRMs, particularly Salesforce, offering numerous features to support team collaboration.
❌ Cons:
There’s no free tier, while the trial period lasts for only 14 days. Moreover, if you choose the cheapest plan, you’ll get a very limited number of campaign recipients per month. Plus, there will be a Yesware branding in your emails. To unlock unlimited sending volume, remove a brand logo, and access in-depth analytics, you must purchase at least the Premium subscription for $45/month.
User reviews:
Yesware can’t boast of positive comments, unfortunately:
My experience with this add-on:
Unlike other top Gmail tools, Yesware wouldn’t install in the Chromium browser I normally use. I found the interface quite confusing and bulky: it’s an entire panel that crowds the mailbox. But worse of all, it delivered some false positive results. As far as I could tell from the Chrome-Stat comments, other users also encountered this issue.
For business users, Gmail can quickly become overwhelming with overflowing inboxes, missed follow-ups, or scattered tasks. Gmail productivity tools ensure you’re not just sending more emails, but also remain organized and focused. Here is a list of the most popular productivity add-ons I’ve tested:
Best for: Professionals who need to manage tasks directly from their inbox
Chrome Store rating ⭐: 3.6/5
Price: Free plan; premium subscription is from $5/month
Todoist is the top Gmail productivity tool for users who don’t need more complex project management solutions. Run projects, manage activities, keep up with deadlines right from your mailbox – this add-on allows it all. You can create tasks, set priorities and reminders, enabling notifications as soon as you receive a new email.
Key features of Todoist:
✅ Pros:
Todoist is easy to use, making it comfortable for structuring your workflow without the need for extra tools. Its Gmail integration looks smooth.
❌ Cons:
The free version is limited to 5 active projects, while advanced features (custom reminders, calendar view, shared projects) require a paid plan. Some users claim problems with the add-on loading.
User reviews:
Users have ambivalent opinions about this Gmail tool.
My experience with this add-on:
Despite some negative comments, the integration worked well for me. Most of all, I appreciated the intuitive interface of this extension. Turning emails into actionable to-dos doesn’t take much time, helping you always remember your essential tasks.
Best for: Professionals seeking a visual, drag-and-drop solution to manage emails and tasks
Chrome Store rating ⭐: 4.1/5
Price: Free plan; paid subscription starts from $12/month
Sortd is the best Gmail add-on for users who want visual task management directly in their mailbox. It transforms your inbox into a Kanban board, ideal for organizing emails into categories such as “To-Do,” “Follow-Up,” or “Later.”
Key features of Sortd:
✅ Pros:
The visual approach makes email management easy, eliminating the need for additional tools like Trello or Asana. It’s the top Gmail tool for small teams and solopreneurs.
❌ Cons:
The interface feels crowded compared to Gmail’s native look. Also, collaboration features require a paid plan.
User reviews:
Most customers love Sortd for its task organization as well as email management features.
My experience with this add-on:
I didn’t encounter any issues either with the extension’s installation or usage. Although having the board inside the mailbox may feel overwhelming for some people, I’m a total fan of the Kanban-style workflow, so I found Sortd’s features very convenient to use.
Best for: Professionals who need a Trello board inside a mailbox.
Price: Free plan for personal use; paid plan for teams starts at $6/ member per month.
Chrome Store rating ⭐: 3.4/5
The Cardbox app helps connect your Trello account with your mailbox. With this add-on, you can turn your email threads into Trello cards, which automatically update when you receive a reply.
Key features of this add-on:
✅ Pros:
This add-on makes task management easier for Trello and Gmail users.
❌ Cons:
Recently, there have been numerous reports of the add-on not functioning correctly.
User reviews:
My experience with this add-on:
A two-way integration between Gmail and Trello is particularly handy for heavy Trello users, thanks to the tool’s intuitive interface. However, Cardbox receives lots of complaints from users, which is why I can’t recommend it as one of the top Gmail tools for now.
Best for: Teams looking for email marketing automation as well as shared inboxes directly in Gmail
Price: 7-day free trial; plans start from $24/month
Chrome Store rating ⭐: 4.6/5
Gmelius combines email collaboration, task management, and automation in one Gmail extension. It also acts as an AI secretary, handling email sorting and replies for you.
Key features of Gmelius:
✅ Pros:
All-in-one functionality with embedded AI features makes Gmelius a valuable asset for teams dealing with a very high volume of emails. Its AI reply assistant learns from your previous replies to personalize future messages better.
❌ Cons:
It can feel overwhelming for solo users. Setting up automation requires a learning curve. Plus, it’s rather expensive for the Gmail add-ons.
User reviews:
Overall, customer feedback is positive, though some users point out occasional bugs and UI issues.
My experience with this add-on:
Gmelius integrated flawlessly with my inbox, so I could get to creating emails and sequences right away. The tool’s AI-powered features are very helpful, but if you want to have multiple outreach features in one package, I’d recommend considering a more compelling solution.
For instance, you can afford more advanced outreach tools, a powerful Gmail integration, and the Personalized AI Email Builder at the same price – Snov.io includes it all in a single package.
Best for: Anyone who wants error-free, professional communication
Chrome Store rating ⭐: 4.5/5
Price: Free plan; premium plan starts from $12/month
Grammarly for Gmail helps you write clearer, mistake-free emails, while sticking to the chosen tone of voice. It checks grammar, tone, and clarity in real time, ensuring your outreach looks professional and polished.
Key features of Grammarly Gmail extension:
✅ Pros:
Instant suggestions make emails more professional with minimal effort. The tool is lightweight and works seamlessly in Gmail’s compose window.
❌ Cons:
Some advanced features (plagiarism and AI detection, audience insights) are locked behind Premium.
User reviews:
My experience with this add-on:
I found Grammarly very useful for catching small errors and improving phrasing. For everyday professional communication, the free version is already enough. But if you write a lot of client-facing emails, you’d better subscribe to Premium to really elevate your outreach and save time.
The following top Gmail tools turn your mailbox into a lean CRM that keeps your pipeline organized.
Best for: Small teams and freelancers who need a simple CRM inside Gmail
Chrome Store rating ⭐: 4.5/5
Price: Free plan; pro from $59/month
You can manage pipelines, track leads, and collaborate with your team via this CRM. It’s a suitable solution for small businesses and freelancers who want simple CRM functionality without extra apps.
Key features of Streak:
✅ Pros:
Native Gmail integration makes it very easy to adopt. The mail merge function is useful for outreach.
❌ Cons:
Advanced reporting and automation are lacking compared to standalone CRMs. The free plan is too limited for serious use.
User reviews:
Streak boasts of many positive reviews from customers.
My experience with this add-on:
The setup was effortless, but the tool itself lacked automation features. I don’t see how bigger teams would use this Gmail extension in 2025.
Best for: Sales teams looking for a full-stack CRM inside Gmail
Chrome Store rating ⭐: 4.8/5
Price: from $30/month
NetHunt CRM brings powerful sales automation and pipeline management into Gmail. It’s built for sales teams that want to handle leads, email campaigns, and customer interactions right from their inbox.
Key features of NetHunt:
✅ Pros:
Very customizable CRM with deep Gmail integration and robust automation. Strong analytics for sales tracking.
❌ Cons:
Higher learning curve than with lighter tools, and the price is steeper than Gmail-first CRMs like Streak.
User reviews:
My experience with this add-on:
NetHunt is definitely the best Gmail add-on for those who want a CRM embedded in their mailbox. But, frankly, it may take some time to set up properly and learn.
Best for: Businesses that want to integrate Gmail into their Zoho CRM workflow
Chrome Store rating ⭐: 3.9/5
Price: Free for 3 users; $3-5/user/month per add-on, depending on the total number of add-ons you buy
The Zoho CRM add-on links your Gmail to the broader Zoho ecosystem. It allows you to view customer information, log emails, and add leads or deals directly from your inbox. It’s best suited for teams already using Zoho products.
Key features of Zoho CRM:
✅ Pros:
Convenient for existing Zoho users – syncs smoothly with the CRM and allows quick access to customer data.
❌ Cons:
Limited use if you’re not on Zoho CRM. The interface inside Gmail feels less polished than other add-ons.
User reviews:
Interestingly, Zoho CRM doesn’t have a lot of fresh reviews. As for the most recent ones, there are certain complaints:
My experience with this add-on:
For Zoho users, this is the best Gmail add-on to keep work streamlined. But if you’re not already in the Zoho ecosystem, it doesn’t stand out compared to other solutions.
Best for: Businesses using HubSpot who want robust email tracking and CRM integration
Chrome Store rating ⭐: 4.4/5
Price: Free plan; paid Sales Hub starts from $15/month
The HubSpot Sales extension brings email tracking, meeting scheduling, and CRM sync into your mailbox. It’s designed for businesses that want to connect outreach with HubSpot’s full CRM and marketing platform.
Key features of HubSpot sales extension:
✅ Pros:
Strong free plan with tracking and scheduling. The best Gmail add-on if you’re a HubSpot CRM user.
❌ Cons:
Full power requires a Sales Hub subscription, which gets pricey. Can feel heavy inside the mail client.
User reviews:
While there are users who are satisfied with the add-on, many report having issues with the features loading, etc.
My experience with this add-on:
It took some time and effort to install and try out different features. Just like Zoho, the main value this solution brings to users who already utilize HubSpot CRM is that, otherwise, having so many features may feel unnecessary.
In this part, I’ll list some of the best Gmail add-ons for calendar, scheduling, or automation that can save time on logistics and allow your team to focus on revenue-driving conversations.
Best for: Professionals who schedule frequent client or team meetings
Chrome Store rating ⭐: 4.3/5
Price: Free plan; paid plans start from $12/month
The Calendly extension makes scheduling meetings from Gmail a one-click affair. Instead of sending back-and-forth emails, you can insert available time slots directly into your message or share your calendar link.
Key features of Calendly:
✅ Pros:
Makes scheduling effortless for both sides, and the free plan covers most basic needs.
❌ Cons:
Customization options are limited unless you upgrade.
User reviews:
Most customers love using this app for its convenience.
My experience with this app:
I like how intuitive this app’s interface is – it’s very easy to set up and use. It’s user-friendly and reliable, without any unnecessary fluff. Although configuring advanced workflows requires a paid version, I think this top Gmail tool is worth the price.
By the way, you can insert meeting links directly into your emails and LinkedIn messages in Snov.io. The platform seamlessly integrates with Calendly, so you can automatically follow up with contacts who schedule a meeting through your campaign.
Best for: Sales professionals who want advanced outreach and automation inside Gmail
Chrome Store rating ⭐: 4.5/5
Price: Free plan; Paid plans start from $34/month
Mixmax transforms Gmail into a full productivity and outreach platform, with email tracking, templates, reminders, and scheduling. It’s marketed as an all-in-one solution for sales reps and marketers.
Key features of Mixmax:
✅ Pros:
The tool combines tracking, scheduling, and automation in one polished extension.
❌ Cons:
It’s expensive compared to similar tools, while its free plan is rather limited.
User reviews:
Overall, Mixmax has lots of positive feedback from users. What is a problem for customers, however, is pricing.
My experience:
I ran into the compatibility issue immediately after installing Mixmax, as it didn’t integrate with the Mailsuite. Once installed, I really appreciated the tool’s modern design and functionality. But I am honest with my review, so I should state here that, unfortunately, it didn’t deliver a message to my Apple mailbox during the test. And personally, for me, that is a red flag.
Best for: Professionals who want better control over email tracking and meeting scheduling
Chrome Store rating ⭐: 4.2/5
Price: Free plan; paid plans start at $4.98/month (billed annually)
Boomerang focuses on scheduling emails, setting reminders, and pausing your inbox to regain control. It’s one of the oldest Gmail productivity tools and is still popular among email users.
Key features of Boomerang:
✅ Pros:
This Gmail extension is very easy to use and reliable for scheduling and reminders.
❌ Cons:
Some features conflict with other top Gmail tools. The free plan is restrictive, and the paid plan can only be purchased on an annual basis.
User reviews:
Most users are satisfied with this Boomerang’s functionality.
My experience with this add-on:
Just like Mixmax, Boomerang didn’t get along with Mailsuite. Also, it didn’t deliver to some mailboxes by niche providers. Otherwise, the extension worked fine. I found it to be overall functional, but clunky compared to other solutions.
Best for: Teams that rely heavily on Zoom for client or internal meetings
Chrome Store rating ⭐: 4.5/5
Price: Free basic plan; pro plan starts from $16.99/month
This add-on for Gmail lets you quickly start or schedule Zoom calls without leaving your inbox. You can insert meeting invites directly into emails, making it simple to switch from email to video call.
Key features of Zoom add-on:
✅ Pros:
Great if your organization already uses Zoom. Removes the necessity of switching apps.
❌ Cons:
The add-on itself is quite basic compared to the full desktop client. Also, user reviews point out stability issues.
User reviews:
Overall, comments are positive. As I’ve just mentioned, some customers report there are instabilities in how the add-on operates.
My experience with this add-on:
The extension worked fine, but opening Zoom directly seems just as easy. And if I’m already logged in to my Gmail account, it’s more convenient for me just to use Google Meet.
The best Gmail add-on for you is the one that matches your goals and workflow. To make the selection process more straightforward, I recommend asking yourself the following questions:
For example, if you need email tracking, the top Gmail tool should monitor link clicks with the highest accuracy. If your goal is increased productivity, it should turn emails into actionable tasks – and so on.
Interfaces with a clean, well-designed UI save time and reduce friction in daily use. They guide you naturally without demanding extra effort.
The best Gmail add-ons should bring value that outweighs the cost. Plus, some offer generous free tiers that cover most workflows without a paid subscription.
Smooth integrations reduce manual work and errors across the platforms. The Gmail add-on that plays well with your CRM and collaboration apps quickly proves its value by making your team more productive and improving your workflow.
❗️Remember: Add-ons have broad access to your inbox, so don’t overlook data safety measures. Make sure the provider has a solid reputation and complies with privacy regulations like GDPR.
Your inbox is where most business relationships start, so it makes sense to manage contacts and deals without leaving it. So if you or your team lives inside the mailbox, there’s no getting by without add-ons. Otherwise, you risk slowing down your workflows and losing a competitive advantage.
The shift toward remote and hybrid collaboration also dictates the necessity of Gmail extensions in 2025. Distributed teams rely heavily on seamless workflows across email, chat, video calls, and CRMs. Add-ons bring all these tools into one interface, reducing click fatigue.
Finally, time is one of the most expensive assets in business these days. Between back-and-forth emails, meeting coordination, and routine follow-ups, valuable hours slip away. Gmail add-ons help you automate repetitive inbox tasks, freeing up hours each week.
I’ve tested 17 add-ons and tried to provide my honest review of each of them based on my personal experience with the tools. I hope this analysis will help you choose the best solution for your goals.
I also picked the best add-on from each category and compiled a toolset I would use for my daily tasks:
