SentSignal Treats Email Opens as Clues, Not Proof

A Gmail extension that tracks open signals, separates likely human activity from suspected proxies, and turns sent messages into follow-up workflows.

Why it surfaced

SentSignal refuses to present a tracking pixel as a confirmed read: its sample log labels events “Likely person activity” or “Proxy suspected,” then keeps the uncertainty out of the summary decision. The site also gives the tool a concrete Gmail workflow—waiting folders, reusable templates, and follow-up actions—rather than stopping at surveillance.
