About Stephanie Duncan

Lifecycle Marketing Strategist & Marketing Operations

Background

I have 6+ years of marketing experience spanning lifecycle strategy, marketing operations, CRM management, attribution, and conversion copywriting. I started in execution and moved into owning the systems behind performance.

I've managed lifecycle programs across 100K+ contact databases, led marketing operations for multi-location organizations, served as Marketing Director, and run Klaviyo programs that generated $146K in attributed revenue in 8 months. I also have DTC founder experience, which means I understand what it costs when lifecycle marketing isn't working.

My background sits at the intersection of two things most people have separately: the customer psychology needed for conversion, and the operational infrastructure needed to make marketing scalable. I'm comfortable in both and I know when each one is the actual problem.

I read consumer behavior research for fun. I spent a Saturday once going through checkout page psychology literature and took notes. I find the gap between what customers say they'll do and what they actually do genuinely interesting. That curiosity is what makes me good at this.

If your lifecycle is underperforming, I can tell you why.

Most teams already know something is off. They need someone to find exactly where it's breaking.
