Mailsuite adds everything Mailtrack users asked for over the years:
Yes — unlimited email tracking, free forever. Free accounts include a "Sent with Mailsuite" signature; paid plans remove it and add link tracking, documents and campaigns.
Mailtrack is alive and well — since 2024 it's part of Mailsuite. Same extension, same team, more features. Your account works as always.
Mailtrack® is a registered trademark of Mailsuite S.L., and the official extension is distributed only through this website and the Chrome Web Store listing "Email Tracker by Mailtrack" — the one with 3 million users and over 11,500 reviews. If you found a similar-looking product anywhere else, it isn't us.
When you hit send, Mailtrack inserts a tiny, invisible image — a tracking pixel — unique to that specific email. The moment your recipient's email client loads it, our servers register the event: the timestamp, the open count, and which recipient opened it in a group email. That signal is what turns your checks green and fires your notification.
Two green checks mean a person actually opened your email — not you, and not a machine. Mailtrack discards your own self-opens, filters automated opens caused by mail scanners and image prefetching, and identifies each recipient individually in group emails. It's the verification layer we've refined over a decade of tracking.
