Top 10 Email Tracking Software [2021 Reviews]

Looking for the best email tracking software?

An email tracking tool can track email opens and other metrics to help a sales rep or marketing executive run effective email marketing campaigns. It’s also useful for anyone who simply wants to know if their email has been opened or not.

In this article, I’ll cover why you need to track your emails and list the best email tracking software.

Three Key Reasons to Track Your Emails

While anyone can benefit from email tracking, it’s especially useful for email marketers.

Here’s why:

1. It Helps You Manage Campaign Interactions

If you’re an email marketer, chances are you send emails to hundreds of people.

However, you can’t manually monitor each interaction, right?

Luckily, an email tracking tool lets email senders know when someone opens or engages with their emails. This way, the email tracking system helps them manage their email campaign interactions without them having to lift a finger!

An excellent email tracking app can track when:

  • A recipient opens your emails.
  • They click on any link present in your email message.
  • They forward an email to someone else, and more.

None of the above is possible if you send emails normally or by using the BCC feature. By the way, you can check out 4 key drawbacks of using BCC in this article.

However, that isn’t all.

You’ll also get an idea of when they opened your tracked email.

This can help you gauge when they’re most active — so that you can send follow-up emails at the right time for maximum engagement.

2. You Get Unique Insights into Your Email Marketing Campaigns

Most email trackers do more than just track email opens and link tracking.

Ideally, an email tracking service will give you detailed reports over different aspects of your campaigns, like deliverability and conversions.

You get information on campaign metrics like:

  • Open Rates (OR): The number of recipients that opened your emails.
  • Click-through Rates (CTR): The number of email IDs that clicked the links in your emails.
  • Bounce Rates: How many email addresses didn’t receive your emails.
  • Unsubscribe Rates: How many email IDs unsubscribed from your campaigns.

How does this help you?

These metrics will help you understand:

  • If your emails are going through.
  • If they’re connecting with your audience.
  • What’s going wrong with your emails.
  • What needs to be changed.

Email senders can use these metrics to fine-tune various aspects of their emails, such as their email openings, to make them more attractive to their audience.

3. It Provides You with the Right Context for Follow-ups

Remember, your marketing campaign follow-ups need to be meaningful.

You can’t afford to bombard your recipients with follow-ups they don’t want.


It’s a surefire way to get you marked as spam, which will harm your deliverability!

Think about it.

You can’t send a weekly follow-up email to someone who unsubscribed recently, right?

With an email tracking system, email senders get actionable insights into their prospects’ interests and behavior. This helps you tweak and customize your follow-ups for maximum engagement.

Here’s how it boosts your outreach:

If you know that a person regularly engages with your mails, chances are, they’re interested in what you’re selling. You can now move them down your sales funnel and maybe give them a call, as they’re primed for a pitch.

An email tracking system helps you understand the kinds of content and links that engage your recipients. This lets you customize your follow-ups to appeal to their interests.

The Top 10 Email Tracking Tools in 2020

Here are the top email tracking tools to check out now:

1. GMassGMass homepage

GMass is powerful email outreach and tracking software that lets you run marketing campaigns from your Gmail inbox. Its robust mail merge capabilities have made it a popular email tracker that’s used by employees from Uber, Google, and social media giants like Twitter, Facebook, and LinkedIn.

With GMass, you can:

  • Automatically track several email campaign metrics accurately.
  • Quickly send sales and marketing campaigns to tons of people.
  • Automatically personalize mass emails on a person-by-person basis.
  • Easily schedule emails in advance.

Here’s a closer look at GMass’ key features:

A) Advanced Mail Merge Reports and Email Analytics

GMass accurately tracks various email metrics to give you detailed marketing breakdowns in your Campaign Report.

What’s the Campaign Report?

The Campaign Report is automatically generated after sending each email campaign and highlights all the core marketing statistics you need.

Here’s what GMass’ automated Campaign Reports contain:

  1. Total Recipients:
    The total number of email addresses to which an email campaign was sent.
  2. Unique Opens:
    The total number of unique email IDs that opened your email.
  3. Didn’t Open:
    The total number of email IDs that didn’t open your email.
  4. Unique Clicks:
    The total number of unique recipients that clicked at least one link in your email.
  5. Replies:
    The total number of recipients that replied to your campaign.
  6. Unsubscribes:
    The total number of email IDs that unsubscribed from your emails.
  7. Bounces:
    The total number of emails that came back as undeliverable because the address was invalid.
  8. Rejections because your Gmail account is over-limit:
    The total number of email IDs that didn’t receive your emails because Gmail limited your account’s sending ability.
  9. Blocks:
    The total number of emails that came back as undeliverable because the address rejected your email as spam.GMass interface showing a Campaign Report

However, GMass’ reports are far better than your regular campaign reports.


Unlike other email marketing tools such as Mixmax, SalesHandy and ContactMonkey, GMass places campaign reports right inside your Gmail account.

You won’t have to open a separate tool or window to access your sales email tracking. Your reports will be waiting for you right in your Gmail inbox!

B) Powerful Personalization

Email marketing is all about making a connection.

And how do you make a connection?

By personalizing your emails.

After all, what would you rather engage with?

Generic marketing emails?

Or those that are tailor-made for you and your needs?

But you can’t manually personalize hundreds of emails. That’s going to take forever!

Luckily, GMass offers you automated personalization features to tailor your marketing emails on a person-by-person basis.

It gives you features like:

As the tool does all the personalizing, you won’t have to lift a finger!

C) Email Scheduling

Timing plays a huge role in email marketing.

You need to send emails at the right time for maximum engagement.

For example, your email campaigns won’t be as successful if people receive your emails at 3 AM, right?

Ideally, you should send your campaigns when your recipients are most likely to check their inboxes.

To help you with this, GMass allows you to schedule your emails in advance to plan your campaigns carefully. Because the tool automatically sends these emails, you won’t have to be online when they go out.

If there’s a change of plans, you can always reschedule your emails via the Gmail Drafts folder.GMass interface showing Scheduling tab

D) Automatic Follow-Ups

After analyzing your campaign responses, you’ll have to send meaningful email follow-ups, right?

But what if you have to follow-up on hundreds of emails?

You can’t do that manually…

Don’t worry.

GMass supports follow-up email automation to automate the process for you.

It can send automated follow-ups to targeted recipients for maximum engagement. You can also customize everything about these follow-up emails, like:

  • The trigger for sending a follow-up. For example, GMass can send a follow-up email when a recipient clicks a particular link or replies to your email.
