Know when your email is read
Add a tiny invisible tracker to your emails and see the moment they're opened and your links are clicked — right from Gmail, Outlook or any webmail.
Open tracking
A ✓✓ appears the moment your email is opened, with the time and device.
Link clicks
See which links in your email were clicked, and how many times.
Right away
Opens show in your dashboard and the extension within seconds.
Private
We never store the body of your email — only the subject, recipients and the open and click counts.
How it works
- 1. Install the browser extension and connect it with your token from this page.
- 2. Write your email in Gmail as usual — the tracker is added automatically. In other webmail, click “Track with iHeartPDF”.
- 3. Watch opens and clicks appear in your account and in the extension.
