About
A lifecycle marketer who thinks in systems, not just sends.
I'm Kevin Castaneda. I've spent 6+ years building lifecycle programs across DTC, SaaS, and creator platforms — for brands doing email campaigns, SMS flows, and CRM strategy at scale. I work at Teachable, where I've seen what separates programs that convert from ones that just send.
