Lumo — Gmail open & click tracking

Privacy-first read receipts for Gmail. See when your email is opened and your links are clicked.

Lumo tells you the moment your Gmail is read. Send email like you always do — Lumo quietly adds open- and click-tracking to your outgoing messages, then shows the activity in a live dashboard. Smart filtering means Apple Mail Privacy, Gmail's image proxy, and security scanners never get mistaken for a real human read, so the signals you see are honest. • See when a message is opened, and when links are clicked • Real-time dashboard + optional desktop notifications • Bot / scanner filtering for trustworthy reads • Works inside Gmail's compose window — nothing else
