Free Gmail email tracking with open, link and attachment insights
Get alerted through Chrome notifications or email the moment your message is opened, so you can time a follow-up while the interest is fresh.
See how many times and exactly when a recipient accessed your email, which helps identify the messages and segments that actually land.
Know when someone clicks a link in your message or opens an attached file, not just whether the email was opened.
Choose a visible tracker to encourage replies, or an invisible tracker when you prefer recipients not to know.
