The 10 Best Email Tracker Software

Let’s explore the features, pros, cons, pricing, and customer ratings of the top 10 email tracking tools available today:

1. GMass

GMass home page

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

With the GMass Chrome browser extension, you can:

  • Automatically track several email 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.
  • Send automated follow-up emails for maximum engagement.

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 breakdowns in your Campaign Report.

The Campaign Report is automatically generated after sending each email campaign and highlights all the core email marketing statistics you need to understand how recipients interact with your campaigns and craft better emails.

Some of these metrics are:

  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 campaign reports inside Gmail

And 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 email tracking reports — they will be waiting for you right in your Gmail inbox!

However, GMass also lets you track your email campaign performance via a dedicated dashboard for maximum flexibility. You can also view your Campaign Reports as web-based reports on both desktop and mobile platforms.

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!

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

You get advanced functionality like:

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

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 here, GMass allows you to schedule your emails in advance to plan your campaigns carefully. As 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.

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 streamline 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.
  • The number of follow-up emails each person receives.
  • The time gaps between each follow-up.
  • The follow-up email message.

Now that we have explored the top email tracker software available today, I’ll answer some FAQs related to email.

4 FAQs About Email Tracking

Here are my answers to some of the most common questions about email tracking:

1. What is Email Tracking?

Email tracking involves monitoring the sent emails to obtain information for business decisions. You track metrics like open rate, click-through rate, and unsubscribe rate to gain insights into the performance of the tracked emails.

2. How Does Email Tracking Work?

Email tracking tools can inform you when your sent emails have been opened and replied to.

This is possible because mail tracker tools insert an invisible tracking pixel in outgoing emails. These pixel trackers can detect the exact time an email has been opened.

An email tracker can also show you whether recipients have clicked on links in your tracked emails or if they’ve unsubscribed from your emails.

3. What Are The Benefits of Email Tracking?

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

1. It Helps You Manage Campaign Interactions

An email tracking tool lets you know when someone opens or engages with your emails. This way, the email tracking system helps you manage email campaign interactions without you 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.

Additionally, you’ll also get an idea of when they opened your tracked email. This can help you gauge when recipients are 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

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 any link 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

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.

For example, 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.

4. Are Email Trackers Legal?

If you’re worried if tracking your emails will get you in trouble, don’t be!

As long as you are GDPR compliant (if you’re in the EU) and follow some email tracking best practices, tracking your emails is perfectly legal. You can follow practices like including a double-opt-in and a one-click unsubscribe option to avoid legal trouble.
