But you can make even more out of Gmail. Using Gmail add-ons, apps, and extensions, you can do a range of things with your Gmail inbox, from using a Kanban board to documenting and managing leads, running a CRM, and more.

2. Gmelius: Editor’s Choice for the Best Gmail Add-ons 🏆

Rating: 4.9 out of 5

Best Gmail Add-ons, Best Gmail extensions, Best Gmail apps, top Gmail Add-ons, top Gmail extensions, top Gmail apps

With Gmelius, you can supercharge your Gmail inbox and turn it into a productivity powerhouse. I found out about Gmelius earlier this week with their recent launch on Product Hunt and decided to test out its features.

I was amazed at how effective and seamless this integration was. Gmelius works with Gmail, Inbox by Google, and G-Suite and has a ton of features to offer for email automation, email marketing campaigns, and security – some of which are listed below.

Gmelius grabs the top spot in this roundup for the best Gmail add-ons.

Key Features:

  1. Sales Automation
    1. Email Tracking
    2. Email Sequencing 🔥
    3. Scheduling and Recurring Emails 🔥
    4. Email Marketing Campaigns
    5. Smart follow-ups
    6. CRM integration 🔥
    7. Markdown
    8. GIFs and Unsubscribers support
  2. Collaboration
    1. Email Sharing 🔥
    2. Shared Labels
    3. Kanban Boards 🔥
    4. Email Templates
    5. Email Notes
  3. Security
    1. Email Stamping 🔥
    2. Trackers Detection

Pricing:

Gmelius comes with the following pricing plans:

  1. Free – free forever, limited email scheduling and follow-ups, 1 Kanban board, up to 5 email templates, and other basic features

3. EmailAnalytics:

emailanalytics gmail addon, email analytics gmail g suite add on

Over the course of the last few weeks, we oversaw a tough competition going on between Gmelius and EmailAnalytics. The latter hit our radar recently, and we decided to sneak into what the program had to offer. So, yeah, EmailAnalytics is slightly better, if not the “ultimate” or the “best” version of a Gmail Add-on or an Extension for that matter.

At its core, EmailAnalytics centralizes not only your Gmail account but also the rest of the apps in G Suite. However, since it is a substitute for conventional emailing through Google based IDs, the devs laid most of the emphasis on email functionality, back to back communication, intuitive design, and many other technical gimmicks.

The tool enables individual users, sales teams, admins, and any number of people to measure essential productivity metrics just like an average email response time. Makes sense? No?

Okay, how about creating a picture of your company’s rush hours when most of the communication happens, and then getting an insight on the same email traffic volume by a particular day of the week, a specific period, or some other time-stamped period? Sounds savvy, I know.

Take a look at some of the main highlights of this software.

Key Features:

  • Sales related email marketing campaigns are a great way of tracking read receipts, goal conversions, and vice versa.
  • It helps to eradicate the shortcomings of a traditional Google email account.
  • Intuitive UI with an overlay of modern-day color palettes.
  • Create your own team and sort users into them as you go by.
  • Set your preferred time-zone and related work hours for insight on communication analytics.
  • Block unwanted data from being tracked with filters.

Pricing:

By default, EmailAnalytics is not available for free. However, there is a trial version that you can use to see what the app has to offer.

  • Pro Package: Starts at $15 per mailbox per month.

Wait, there’s more!

Since it is a communication tool, the team behind EmailAnalytics has reportedly worked hard to ensure that end-user security remains the number one priority. On that note, the devs have taken the following measures to fortify user privacy for all EmailAnalytics subscribers and non-subscribers alike!

  1. EmailAnalytics is required by Google to undergo an annual 3rd party security audit. The auditor is Leviathan Security Group that has enabled the company to maintain its high-security standards.
  2. EmailAnalytics uses Gmail’s API to ensure 100% privacy & security.
  3. Emails are retrieved through a fully-encrypted connection.
  4. All communication between Gmail and our servers is protected using AES 168, 256-bit encryption and exchange mechanisms based on elliptic cryptography.
  5. None of your email data is stored at company servers; they briefly access the data for analysis, and that too in an encrypted format.

For more information, you can log on to EmailAnalytics’ official website at https://emailanalytics.com/.

  1. Amazing list, Steve! My favorites being Streak and Checker Plus.

    And I’m proud to say I just launched PurposeTab, which is a free Chrome extension that shows your goals, habits, to-do’s and more – every time you open a new tab. It’s your personal clarity dashboard. I was tired of remembering to check multiple different apps instead of automatically seeing all of those things at a glance.

    I think you and the Productivity Land readers would like it!

  2. I’m very happy to read your post. thanks for the little information you put on here, . now I see the reason we should have Gmail App on our mobile phones as devices.

  3. Rather idiotic move on Google’s part to remove apps – effectively putting thousands of programmers in the poor house – now the browser is really more of an “”also ran”” – do we all really want a large number of little tiny icons up in the right hand corner where we have to remember what each is – Google is loosing it’s soul and even it’s employees have begun to wonder what kind of corps they are actually working for, especially after Google recently decided that it was a good idea to be a part of a murderous military contract…

  4. I like “Contacts Inbox” add-on that integrates Google Contacts and Stripe info from senders. Also the extension “Auto Open Add-on” lets you open the add-on you choose automatically when Gmail starts.
