Email Open Tracker – Real-Time Gmail Read Receipts & Tracking

About

Know the moment your email is read.
  
  Email Open Tracker adds real-time open tracking to Gmail — no new tabs, no extra setup. Send an email, and you'll know exactly when it was opened, how many
  times, and on what device.

  Real-time open notifications
  The moment your email is read, it shows up in your activity feed with a timestamp, device, and browser. No delays, no guessing.

  Gmail toolbar counter
  A live pill appears directly in the Gmail thread toolbar — showing total opens at a glance while you're reading the conversation.

  Full activity timeline
  Every open event across all your tracked emails, in one place. Scroll through your history, filter by thread, and see the full picture.

  Sent folder status
  Open status appears across your entire Sent folder — so you can tell which emails have been read without opening each one.

  Proof of receipt PDF
  Generate a timestamped certificate for any tracked thread. Useful when you need to prove an email was received and read.

  How it works

  Install the extension, open Gmail, and sign in. Every email you send will be automatically tracked. Open the side panel at any time to see your activity feed.

  No email forwarding. No BCC. Nothing changes about how you write or send — it just works in the background.
