About

What is KillBounce?

Three-layer email verification with a real SMTP probe not regex pretending. Built because the $80/month tools couldn't handle catch-all domains on Google Workspace (anti-enumeration tricks every regex-and-DNS approach into a false "accept all"). KillBounce opens a live SMTP session with the recipient server and reads the actual response. $4 per 1,000 credits. Pay-as-you-go. Credits never expire. Public legal stack at /trust for procurement.
