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

so far, working good
There are a few bugs at the moment with the tool. Have just started using it. Let's see.
good
That tool is awesome. I just fixed the conversion tracking error. During conversions, it wasn’t showing desktop notifications or other tracking events.
TrackMailbox has given me an opportunity to track mails and their openings easily. Great tool!
So far fully reliable tracking. TrackMailBox is on its way to get 6 stars - so please increase the maximum review stars... Peter
I tried a few and this is the one I feel the most comfortable with and it works well, I use it a lot.
Handy! Works just as described and offers, for free, what many services nickel and dime you for. Bravo!
Outil très utile !
I have been using this email tracker for the past two months and it has been a wonderful experience. What I love most is that the receiver has no idea they are being tracked, which makes it incredibly useful for senders like me to monitor how my emails are performing. Highly recommended!
