What TrackMailBox is
TrackMailBox is a free Chrome extension for Gmail that tracks email opens and link clicks. It reports when recipients open messages and how many times, and records which tracked links they click and when. Desktop notifications can alert users to both events in real time. In Gmail’s Sent folder, badges label messages Opened, Clicked, Unopened, or Untracked. TrackMailBox says scheduled Gmail messages receive tracking automatically. Its Best Time calendar analyzes engagement patterns across regions and time zones to suggest sending hours. Users can create, search, manage, and insert templates with subject lines and body content from Gmail’s compose window. The Free Forever plan costs nothing and includes unlimited tracking, notifications, click tracking, open history, an analytics dashboard, Chrome extension access, and email support. Opens are detected with an invisible 1x1 pixel, while tracked links pass through the service’s servers. Its privacy policy says email bodies are not stored. The help center notes that corporate firewalls may block tracking pixels and that tracking can be delayed.
