The more data you have on your email activity, the easier it is to understand what works, and what doesn’t.

Email tracking tools can help you gather data on how your recipients are interacting with your emails, whether it’s for sales outreach, customer support, or to improve your email marketing efforts in general.

In this guide, we’re going to look at the best email tracking software that you can use on Gmail, Outlook, or as a standalone platform, to help you improve your ROI on your email outreach efforts.

  4. 8 Best Email Tracking Tools to Improve Your Email Usage

Let’s dive in.

What is Email Tracking Software?

Email tracking software connects with your email account and lets you track actions like:

  • Whether someone opens your email or not

  • When they opened your email

  • The reply rate on your email campaigns

The functionality will depend on the tool you’re using, and your goals. For example, a sales-focused email tracker will help you track different metrics to a productivity or customer support email tracking tool.

How does Email Tracking Software Work?

There are two main types of email tracking software.

The first is standalone platforms. Once you create an account, you can log in to these platforms and manage your email activity from them without ever touching your inbox. These are often more powerful, but require you to commit to using that platform for your email activities.

The second type of email tracking tool works as browser extensions. They add new functionality to your existing Gmail or Outlook email inbox, and you’ll see them overlaid onto the inbox you use. These are generally more lightweight solutions.

To track how prospects engage with your emails, they insert a tracking pixel into the email body, which will notify you when your email is opened. If you include links, there will be a custom tracking URL that registers whenever the link is clicked.

One thing to note is that if your recipients have the “Ask before displaying external images” option enabled in their email settings, your tracking pixel won’t work if your prospect doesn’t load images.

There can also be a small impact on email deliverability, so track your emails with caution and always run regular deliverability tests. 

Benefits of Using Email Tracking Software

1. Understand How Prospects Interact With Your Emails

The first main benefit of an email tracker is that you know what happens to your emails after you hit ‘send’.

For example: 

  • How long after sending did your prospect open your email?

  • What time of day do most people open your emails?

  • Did they click any links, or forward the email on?

You can then use the data to optimize your future email sending habits. If you see the majority of your prospects open your emails between 9 and 12 am, you can schedule your next outreach campaign to send during that time period.

2. Improve Your Email Templates

You can use your reply rate and click-through rate data to gauge how engaging your emails are to your recipients.

If you’re seeing a reply rate of 10% or less, you know there are improvements you can make to your emails to improve how well they resonate with recipients. 

If you include a demo booking link as your call-to-action but no one is clicking it, you can test using a simple, text-based call-to-action in your next email campaign.

It’s worth noting that email trackers won’t tell you what to change in your email templates. They’ll report the data back to you, and then it’s on you to update your email templates.

3. Plan Your Follow-Up Emails

Tracking email activity can give you insights into when to follow up with prospects.

For example, if you sent a sales outreach campaign three days ago and then saw that your email was opened, but you didn’t receive a reply, you know it’s going to be a good time to follow up. You’ll also see that they’ve read your last email, so they’ll already have some context when they see your name in the inbox again.

If someone didn’t open or read your email, you can send a follow-up with more information to help start a conversation with your prospect.

The more context you have, the more personalized each interaction with your recipient can be.
