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

Its great when it works... ughhh
It is marked as suspicious and unvarified by google
I know over time there will have to be a cost for this, and I truly hope the programmer sticks with it. This so far is a really simple to use system. People sometimes need just simple, and this is it
very useful and best things is free and unlimited emails tracker. great experience
The service, options, dashboard, overal usage - and that all for free, forever - and it works - what's not there to like?
very helpful!!
Amazing free email tracker without limit. Thanks, and God bless you for this Chrome Extension. You can just install this and be a totally idiot because it's enabled automatically and you get all you need and want. Thanks again and God bless you and everyone that use it!
I have used better, given that this feels like a rush to market. Too many holes.
I had high hopes when I found this one, and it just so happens it doesn't track emails sent to Yahoo addresses, which is exactly what I need it for now.
Excellent Service and Light weight
