The Best Gmail Tracking Extensions You Can Possibly Find

Eserto Editor

Worldwide, Gmail is one of the most used email services. There are many reasons why it enjoys such popularity.

One major reason relates to marketing. However, the power of a Gmail account will not be complete with only the basic account. To unleash the full marketing potential more is necessary.

To this end, there are many browser extensions available for marketing pros. One useful feature that is available through these extensions is email tracking.

In different fields of business, email tracking is becoming more and more relevant. It is often of interest to the sender to know if the addressee receives the email.

This is where email trackers come in handy.

For example, sales reps benefit from knowing whether someone received an email. It allows them to keep track of their most interesting leads.

With this information, it is easier to generate income by closing big deals. It also opens the way for them to automatically send follow-up emails.

Many email trackers are available and they are easy to install and use.

It is nice that there are a lot of choices, but which one is the best for you?

This article lists the best ten Chrome extensions for Gmail tracking. It discusses the important features and pricing for each option.

How Does Email Tracking Work?

There are different ways to track emails and retrieve various details about the user.

Often, the mail tracking software inserts a small, transparent image into each email sent. This image is a 1x1 pixel in size and is also called a ‘tracking pixel’.

This pixel provides the requested information to the tracking software’s database when the recipient opens the email. The user can then review the information in the database.

The unique feature of the mail tracking pixel is that it is silent. It works in the background without the email recipient being aware of it.

What information can mail tracking provide? Here are some of the parameters that are retrievable, depending on the software:

  • Who?
  • When?
  • Where?
  • How often?
  • What device did the recipient use?
  • Which attachments or links did the recipient open?

With the information in hand, the sender knows whether an email ended up in the inbox or the spam folder. Or if the email was somehow blocked from delivery.
