About

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
