About the startup

Pitchblock connects to your inbox and filters out cold sales emails before you ever see them. A three tier system combines pattern recognition, cold email platform detection, and AI analysis to catch outreach while protecting every real email. Every email that matters lands exactly where it should. Setup takes sixty seconds and there is nothing to configure after that. Your inbox just gets quieter.
