Overview
Product summary
Review the store description, core capabilities, and common use cases.
TrackMailbox is a free, unlimited email tracking extension for Gmail — with no signatures, no branding, and no hidden limits.
Know exactly when your emails are opened, how many times they're read, and when your links are clicked — all in real time, directly inside Gmail.
WHY TRACKMAILBOX?
Most email trackers either add embarrassing "Sent with [Tool Name]" signatures to your emails, cap free tracking at 10-20 emails per month, or lock basic features behind expensive paid plans.
TrackMailbox is different:
✅ Truly free — no paid plans required for core tracking

just amazing best one so far for free
I’ve been using this email tracker extension for the past 2 months, and it’s honestly one of the best extensions I’ve come across. It’s very easy to use, works smoothly, and does exactly what I need without any complications. The best part is that it offers free unlimited tracking without adding any signature, which is rare. Highly recommended for anyone looking for a reliable and simple email tracking tool!
Easy to use and reliable
Love it.
Love it. Almost everything I want from a free mail tracker. But one thing -- I want to see the IP address! Also, when I write an email, sometimes I need to save it as a draf, exit, then go back in so I can scroll down to the send button.
I installed the extension, but it requires you to sign into your Gmail account in order for it to work. What's even worse is that even though I signed into my Google account more than once, it still says I have to sign in! And so far, none of my outgoing emails have been tracked yet. I don't know what's going on or why this isn't working, but I am now uninstalling it. 👎
Great Extension but the only problem is, it tracks the email when receiver opens it on desktop but not on mobile phones.
So far good. Clean and easy to use interface. No ads. Cons: - not able to deactivate link tracking which uses a really obvious domain for the links which can lead to users not feeling secure to click the link - opening your own sent folder will trigger tracking which leads to false stats - one can not delete entries in the stats
Very helpful free extension on chrome
awesome chrome extension - tracker. this tracker has a beautiful and really helpful feature call template. which is very useful for recurring emails. keep it up.
