SentSignal – Email Tracker for Gmail

Free unlimited email tracking for Gmail with open history, follow-up reminders, local folders, and reusable templates.

SentSignal adds lightweight open signals and follow-up organization directly to Gmail. Turn tracking on beside Gmail's Send button, see the time and number of open signals in Sent, and move messages into a Waiting queue or local project folders without uploading the contents of your inbox. Main features: • Unlimited open-signal tracking on Free and Pro • Exact signal times with proxy-suspected activity labeled separately • Waiting queue with follow-up dates and notes • Drag-and-drop local folders for visible Gmail rows • Reusable text, email, image, and banner templates • Free plan with three folders and three templates • Pro plan with unlimited folders and templates and control over the recipient badge • 15 interface languages Open signals are activity indicators, not proof that a person read a message. Image blocking, forwarding, privacy proxies, and security scanners can suppress or create signals. SentSignal does not upload or index the contents of your Gmail inbox.
