Today, messaging is wired into our digital lives and the way we communicate with each other both privately and professionally.

Messenger apps are on the rise, but does this mean the days of email are gone? We don’t think so. With extensions like MailTrack for Gmail, you can bring some of the features common for instant messengers into email. For example, to track if the recipient has opened your email.


I had the chance to chat with Eduardo Manchón, Co-Founder of MailTrack about their email tracking tool and tips on how you can boost your email productivity.

Tell us about the people that work on MailTrack for Gmail.


We are 10 people now working on this email tracking tool, six of them developers. We managed to create and maintain a light environment, in which everyone talks with everyone. This gives us the freedom to share ideas and help each other out when it is possible and needed. We’re also very proud of our small office in downtown Barcelona, Spain, with a great terrace. We’ve been throwing barbeque parties almost every month.

We’re all used to knowing whether someone has read our messages in messenger apps. Why do you think that has been the case?

We just all became used to that feature when using Facebook Messenger, Skype, WhatsApp and iMessenger. At first, we all thought it would be weird to know if our recipient got our message. But, nowadays, we value that information. That is why we started working on an email tracking extension for the most popular email provider.

How does your email tracking tool for Gmail boost productivity?

Since MailTrack tells you if your email was read or not, the first and most important productivity gain is the fact that you don’t have to follow up your recipient with messages and phone calls to simply ask if they saw what you sent them. So, the gain here is quantitative.

There is a qualitative gain as well which is essential: MailTrack`s email tracking helps your emails become more relevant. Over time, our extension helps you learn what works best, so you can improve your tactics and strategy when communicating with people.

Your follow-ups can focus only on what is valuable to your recipients, not “just checking if”, because you already know if they read what you sent. So you can see the overall effect here over time. More quality emails, and fewer of them. Who doesn’t want that?

What are your top tips for efficient emailing?

That’s definitely something we’re experts on. The most important thing we’ve learned becoming experts in email is to be human. Nowadays, we’ve become so used to the flood of marketing messages and techniques everywhere that everyone has become numb to their effects.

So, don’t overthink your emails in strategic terms. Keep your texts short, and to the point. Write descriptive subject lines that inform your recipient what your topic is, and do some research on Google to find out what they value, what is important to them.

Keep it relevant, straight and short.

What is coming next for MailTrack?

We’re very excited about our prospects. We’ve just released our add-on for Opera for computers. Our developers are working on an extension for Inbox for Gmail as well. We’re also working on features that will be released in the fall. MailTrack has just passed the 1 million sign-up threshold, and we’re about to break even and make our business sustainable. Our ambition is to become the #1 email tracking solution in the market by 2017, and contribute to keep email pertinent and productive.

    Awesome this is a useful extension

    • Yvonne Gonzalez

      Whoa! Glad you like it Adad! Comes in handy for sure! 🙂 -YG

  • Wizardling

    I loathe message tracking and always disable it on on my side so no one can see if I’ve done anything with their message.

    • Yvonne Gonzalez

      It is great to have that option as well. ;D

  • Pierre771

    The feature is interesting but I’m not sure it’s good for confidentiality…
    Chrome version is more recent

    • Yvonne Gonzalez

      I agree Pierre. Feature is interesting. 🙂

      Why is that you don’t trust the confidentiality?

      • Pierre771

        Hello Yvonne Because when you install it, a lot of authorization are required to Google to read the messagery. There is another pb : the feature works only if your recipient read the pictures of his mails. It supposes he has given the authorization to read them by default (it’s not my case, for example) or he has given the authorization for the sender or for the message : it’s the great weakness of your extension with the other pb I mentioned (privacy)
        I found the info in this article (so sorry, it’s in French)

        • Yvonne Gonzalez

          So the biggest concern is that you can only read it when there is an image available? Is that a common issue you have seen on the extension?

          • Pierre771

            No : your extension, when the user decides to follow a mail with it, creates in your mail an attachment, a very small picture (one pixel) the presence of which is necessary to the recipient to send an invisible acknowledgment (read the French article I indicate above). I the recipient blocks the pictures, (if’s often the default option), the extensions doesn’t work
            I you dont’ read French, there are automatic translators and there are certainly articles about it in English or Spanish
            I understand you are not a technician but ask to your collegues developpers to confirm it

  • Very nice information. When i am entering my site with opera browser it extention track my gmail

    • Yvonne Gonzalez

      Thank you! Glad you enjoyed it. 🙂

  • Pierre771

    Apart from privacy, there is another pb : the mechanism works only if the recipient reads the pictures of the mails he receives (I personnaly don’t)
    This is a very complete article about it (sorry, in French)

    Valve system is kinda awkward for new players it only allows you to play 2 games per day until you get your first rank. So if you don’t like wasting one week just to get ranked, you can check our section and chose your preferred CSGO Ranked Accounts.
