Most email finder tools pull from static databases of scraped email addresses. These databases go stale as people change jobs and companies update their email infrastructure. Signal Plug takes a different approach: every search performs a live check against stoplight.com's mail server using SMTP verification. This means results reflect the current state of Stoplight's email system — not a cached result from months or years ago.
Signal Plug enriches every result with supporting data: a confidence score (0–100), deliverability status (Valid, Risky, or Catch-all), job title where available, and LinkedIn profile URL. This context helps you prioritize which Stoplight contacts to email first and personalize your outreach before you hit send.
