About SendHeat
Stop guessing if your emails are being read.
SendHeat is the ultimate stealth email intelligence engine built directly into Gmail. Know exactly when your leads open your emails and click your links, all without them ever knowing.
Unlike amateur trackers that leave ugly "Sent with..." watermarks or trigger spam filters, SendHeat operates on a 100% invisible, zero-knowledge architecture. Your emails look perfectly normal, but your backend Command Center lights up with real-time analytics.
🔥 CORE FEATURES:
• 100% Invisible Tracking: Zero read-receipt popups and zero watermarks. Your recipients will never know they are being tracked.
• Hot Lead Radar: Set custom thresholds (e.g., "Alert me when a client opens this contract 4 times"). SendHeat will instantly ping your private inbox when a lead turns "Hot".
• Link Click Mapping: Sending a pitch deck, real estate listing, or contract? We silently map your links so you know exactly what they clicked.
• Command Center Dashboard: View your complete sending history, open rates, and engagement metrics in a beautiful, dark-mode analytics dashboard.
• Zero-Inbox Access: We prioritize your privacy. SendHeat never reads your inbox history, never harvests your contacts, and only tracks the specific emails you tell it to.
Perfect for founders, real estate professionals, sales teams, and anyone who needs to know exactly what happens after they click "Send."
Install SendHeat today and turn your Gmail into a revenue-generating radar.
