Top 10 Email Tracking Chrome Extensions (Apps) for Gmail/ Outlook

Here’s a detailed look at the ten best Chrome extensions for email tracking in Gmail and Outlook:

1. GMass

Gmass homepage

If you’re a Gmail user looking for an all-round email tracker Chrome extension, then look no further than GMass.

GMass is a powerful email tracker and outreach tool used by employees from large companies like Twitter, Google, LinkedIn, and Uber to skyrocket their email campaign management.

However, its outreach capabilities aren’t just used by large companies.

It’s also perfect for solopreneurs and organizations like schools and churches to send email campaigns right from the familiar Gmail interface!

GMass helps you:

  • Personalize your email outreach campaigns right from your Gmail inbox
  • Measure campaign performance with detailed reports and analytics
  • Schedule your emails and follow-ups easily
  • Automate the follow-up email process
  • Perform extensive mail merges in no time

Additionally, it’s super easy to get started with GMass.

Simply download the Chrome extension from the Google Chrome web store and start using it!

Ideal for: Large companies, startups, email marketers, solopreneurs, and anyone else looking to boost their email outreach.

Compatibility: GMass works with Gmail and can even connect with the Gmail mobile app for Android.

GMass Key Features

Here’s a quick look at some key features of the GMass Chrome browser extension:

A. Detailed Analytics

Since email tracking is all about knowing how well your emails are doing, GMass offers you all the email tracking metrics you’ll ever need!

When you run an email campaign, GMass generates a Campaign Report that contains metrics like:

  • Total Recipients
  • Unique Opens
  • Unique Clicks
  • Replies
  • Unsubscribes
  • Bounces
  • Emails not sent due to Gmail’s email sending limit
  • Blocks

This way, you can quickly determine how well your emails are doing and where you can improve your email performance.

B. Automatic Email Personalization

If you want your emails to really resonate with your audience, you need to personalize them.

After all, nobody likes receiving generic, templated emails, right?

Manual email personalization can take hours, but GMass lets you personalize within a few minutes!

When you’re looking to send out a bunch of emails in one go, GMass will help personalize your emails by:

Check out GMass’ complete personalization features here.

C. Simplified List Building

One of the core parts of any email campaign is an email list.

And with GMass, building one doesn’t have to take forever.

You get tons of different ways to create an email list quickly in GMass, like:

  • Run a search in your Gmail account and let GMass compile a list from the results.
  • Pick a label in the Gmail interface, and GMass will compile a list from that label.
  • Build an email list through email notifications.
D. Automate Follow-ups

Not everyone is going to respond to your emails all the time. Fortunately, GMass automates your email follow-ups to ensure that your emails always stay on your recipients’ radar.

You can even customize several aspects like:

  • The frequency of follow-ups to be sent
  • The total number of follow-ups each recipient receives
  • The message each follow-up email contains
E. Bypass Email Sending Limits

Most email clients (like Gmail and Outlook) limit the number of sent emails every day.

For example, with G Suite, the limit is 2,000 emails per day, while Gmail caps the daily limit at 500 emails.

However, these restrictions can severely limit your outreach if you’re running a massive email marketing campaign.

Don’t worry! GMass has a way around this and can connect with external SMTP providers like SendGrid and Mailjet to send a virtually unlimited number of emails every day — right from your Gmail inbox!

F. Email Scheduling

With GMass’ email scheduling feature, you choose when you want to send out a mass email campaign.

You can:

  • Pick from a list of pre-configured future times.
  • Enter a custom date or time.
  • Alter the time or date after scheduling an email.

GMass Pricing

Unlike most other tools, GMass has an extremely user-friendly pricing structure:

  • Individual:
    • Standard: $25 per month or $225 annually. Includes unlimited emails, contacts, and campaigns. Plus mail merge personalization, Spam Solver, and dozens of other features.
