Mailtrack.io shows you when your email has been read, now available for Inbox

Add as a preferred source on Google

This is not an extension for the faint of heart. If read receipts on iMessages freak you out, then read no further — this is not the tool for you. If, however, you want to know that you are being ignored, rejected, or otherwise put off, then go ahead, install Mailtrack. It’s a simple, easy-to-use read receipt for emails that can be equal parts incredibly useful and disheartening.

Today, the Barcelona-based startup released its newest version for Inbox by Gmail. One of the largest releases from the Mailtrack.io team to date, this latest update lets you see whether or not your email has been opened, how soon after it was received it was open, and how many times sit was opened. If that sounds like information overload, we understand — sometimes, ignorance really is bliss.

But hey, if you’re of the opinion that knowledge is power, then you’ll be joining the more than 1.5 million folks who have signed up for Mailtrack in a little more than three years. Indeed, during the startup’s short lifetime, it’s seen 300 million emails sent with its tracking feature. 

Today, the free Mailtrack extension is available for Google Chrome, Firefox, and Opera. It emulates the popular check mark-based interface used by Skype, Facebook Messenger, and WhatsApp to notate whether or not your email has been read, and while it has plenty of competitors, it looks like it’s leading the field. Indeed, the Mailtrack team told Digital Trends, it has recently surpassed by Streak and Yesware in its number of Chrome users.

“Our users install and keep Mailtrack because of the simplicity of our concept, so we’re investing in taking it everywhere. While it’s our intention to eventually create a version for smartphones, we’re currently focused on taking Mailtrack to Outlook.com,” co-founder Eduardo Manchón said, “We’re strong believers in the survival of email as an essential communication tool for business. Email is incredibly useful, so we want to do our part in making it smarter and more productive.”

The best free VPNs for 2026
The best free VPNs still come with compromises, but a few offer enough privacy and flexibility to be genuinely useful.
Proton VPN UI

A virtual private network (VPN) encrypts your internet traffic and routes it through a server run by the VPN provider. Websites see the VPN server’s IP address instead of yours, and you can get around geo-blocks, censorship, and ISP throttling. The best VPN services are paid, but there are still a handful of free options that do the job well. 

Most free VPNs come with a hidden cost, because running servers isn’t cheap and a company that doesn’t charge you has to make its money somewhere else. Many do so by logging your browsing activity and selling it to advertisers, while others flood you with ads and track you across apps.
