About
I'm Karl Kyamko, a GTM Engineer and cold email specialist based in the Philippines. I've spent years in the trenches of B2B outbound — not as a strategist who talks about it, but as the operator who builds and runs it.
Through Smart Inbox Leads, I help B2B companies build outbound infrastructure that actually works — from the first DNS record to the first booked meeting. I also build AI SDR systems that classify replies, deliver personalized lead magnets, and book meetings without human intervention.
My methodology is rooted in Jay Feldman's Lead Gen Insiders framework, and I've validated every system with real campaign data across multiple industries.
