“Hey, Mike! I saw you opened my email twice. When can I expect an answer?”. You don’t want to hear that kinda question while chilling by a water cooler. Yet, with the abundance of tools for email tracking, most of your inbox is likely already tracked with sophisticated tools. Want to join the tracking party too? Check out our list of the best free email trackers!

To track or not to track?

Email tracking is hardly a new thing. It’s been penetrating our inboxes and sending back the (not necessarily desired) information for quite a few years now. 

According to the 2018 Princeton University study, 70% of tested emails “contain resources categorized as trackers by popular tracking-protection lists”. 

Another study from One More Company (OMC) released in 2017 indicated that 40,6% of the 1,5B+ emails checked contained tracking software. 

Whether the true number is 40, 70 or anywhere in-between, it’s safe to assume tracking is nearly everywhere and more and more of it will be present in our lives. Even if we don’t realize it’s actually happening.

How do email trackers work?

There are various methods for tracking emails and various parameters people want to track. Email opens and clicks on links are amongst the most common ones. Some tools will also tell you which device a reader used to open your email, where they are located or what they did after clicking on your link.

There are three main ways to track emails.

Read Receipts are available with some email clients and allow for requesting a read receipt from an email recipient. It’s a non-intrusive way. Recipients need to either opt-in for sending such receipts in the client’s settings or confirm each receipt manually. Due to this, Read Receipts are not very reliable and, as such, have become rather rare these days.

Tracking Pixels are tiny, 1px x 1px transparent images attached automatically to emails. Each pixel is loaded with an individual tracking number. When an email (and a corresponding image) is opened, a message is counted as opened. Tracking Pixels are used by almost every email tracking software these days.

Trackable Links are links modified automatically with individual sets of characters. When such a link is clicked or tapped, a server logs such an event and is able to determine which particular links were clicked and by whom. With some tools, it’s able to also determine what happens next. Trackable links are also widespread in our emails.

Best free email tracking software platforms

Below you’ll find a number of tools for tracking your emails. They all come on a free or a freemium model so you’ll be able to use each without any expenses. There are also a number of tools that come with a free trial but to continue you need to upgrade to a paid plan. We don’t include them on this list. Only free stuff this time! 🙂

Mailtrack for Gmail

Mailtrack is a basic, free plugin for Gmail and Chrome. It lets you check if emails have been opened in a very visual way – with ticks. If an email was sent, you’ll see a single tick. Two of them mean an email was opened by the receiver.

On the free plan, you can send an unlimited number of emails. Each will, however, come with “Sent with Mailtrack” inserted into your email signatures. Annoying? You can upgrade to a premium plan available for $4.99 monthly or even $2.49 monthly when billed annually. The paid plan also comes with a set of statistics, such as the percentage of emails opened or links clicked. With this plan, you can also use a Mailtrack addon on Android devices.

Right Inbox

Right Inbox is an extension that brings your emailing efforts to the next level. With this tool, you’ll get all the functionalities that you wish Gmail included as standard. You can schedule emails to be sent later, set up automatic reminders, and add follow-ups that will be sent automatically if your prospect doesn’t reply.

One of the best aspects of Right Inbox is its flexible pricing model. Install the app, and you’ll immediately be able to use many of the best features free of charge, but with 10 emails a month limit.

Google Analytics

Google Analytics might not be the most commonly mentioned in the context of email tracking. After all – it’s a web tracking platform after all. But there’s more to it than you’ll read in many tutorials.

Google Analytics can be also used for tracking clicks as well as email opens.The first one offers advanced insights into what your recipients click on and where they navigate later on. The latter, though, is quite limited and a bit tricky to set up. You can track if the email was opened but you won’t know if a recipient keeps coming back. You also won’t be able to use GA with web-based email clients, such as Gmail.

Tracking emails with Google Analytics is free so, despite its limitations, it might be worth your attention. Probably you should consider using it alongside other tools for email tracking. And even more likely, you should read our detailed article to tracking emails with Google Analytics.

Limitations of email tracking

Before you start tracking your emails, you should be aware of several limitations that might impact your results.

Nearly all platforms we mentioned attach a tiny, invisible pixel for the purpose of tracking email opens. This pixel is treated as an image. Some email clients block images from being displayed by default. Some others (rather old ones) are simply not capable of displaying HTML emails and will opt for plain text, stripping all attached images. In both of these cases, an email open might not be recorded as a tracking pixel won’t be loaded.

Also while forwarding emails, some clients may strip them of images. While a tracking software will report an initial open, an email may be circulating around a company network without any further reports. 

In other news, Outlook users can also cause some discrepancies. When new emails arrive, they’ll end up in Outlook’s preview pane. At this time, a tracking pixel can be downloaded even though a recipient won’t even glimpse on a message. 

Finally, some users might be just blocking tracking pixels from loading in the first place in attempts to protect their privacy. While their use is not widespread, such plugins are easily available on the web.

By all means, don’t give up on email tracking because of these limitations. Just keep in mind that regardless of the software you use, the results may not always be 100% accurate.

Testing email tracking software with Mailtrap

Once you decide on one of the above-mentioned tools, you’ll probably want to check how it really works before sending out emails to your mailing list. The obvious approach may be sending your colleagues a bunch of emails and comparing the results with their actual behavior. 

However, there is a better way to go about this, and that is using Mailtrap Email Delivery platform. The platform consists of an Email API and Email Sandbox. Both of these can help in testing emails, sending, and tracking them. 

Using the Sandbox, you can run tests in a safe environment from staging without worrying about the limitations mentioned. Besides HTML/CSS validation and spam analysis, Email Sandbox lets you capture the outgoing SMTP traffic and review the tech info.

With the help of Email API, which has a reasonably quick setup process, you first and foremost send emails and then gain access to rich insights that track how your email deliverability is performing and help you understand what needs to be improved.
