Never miss an open
A toast appears in Gmail the second a tracked email is opened — who read it and which subject — without leaving your workflow.
Context
Jump from an alert to the thread. The side panel or Outlook pane shows open count, device, and timestamps.
Timing
Reach out minutes after an open instead of hours later — while your message is still top of mind.
How it works
Add the extension or add-in and connect your Flexus TrackMail account.
Enable browser or Web Push when prompted — one-time setup.
Every open on a tracked message can trigger an alert in real time.

Catch investor interest before the inbox moves on.
