The free email tracker for Gmail
Know who opens your emails, when, and how many times — right inside Gmail. Free, unlimited, no card.
Kikili tracks your email opens for free, with no limit. Install the extension, write from Gmail as usual, and see in real time if you've been read. Kikili PLUS (€2/mo) adds link-click tracking.
Actually free, actually unlimited
Most trackers give you a handful of "free" emails, then push you to a plan. With Kikili, open tracking is free and unlimited, for everyone. No quota that runs out at the worst moment.
How it works
- Install the extension on Chrome or Firefox.
- Connect your account in one click.
- Write and send from Gmail, as usual.
- The moment it's opened, you get a notification and it shows on your dashboard.
Under the hood: an invisible pixel is slipped into your email. When the recipient opens it, the pixel loads and the open is recorded — nothing for them to do.
What you see
- Who opened your email (and how many recipients).
- When — the exact time of the first open.
- How many times — an email reopened several times is a signal.
