Do your flows look set up on the surface but abandoned carts are still slipping through, welcome emails are underperforming, and repeat purchases just aren't happening consistently? If this sounds familiar, your retention system is leaking revenue every single day. And that's exactly what I help DTC eCommerce brands fix. I am a Klaviyo Email Marketing & SMS Retention Specialist who helps Shopify and DTC eCommerce brands, particularly in health, beauty, wellness, and supplements and turn their email lists into predictable revenue channels through high-converting flows, lifecycle automation, advanced segmentation, and data-driven campaign strategy. I operate as a full ownership partner, not an order-taker. I come to you with what I'm planning to send, why it will work, and how it ties to revenue. You approve. I execute. My goal is simple: 👉 Build and manage a complete Klaviyo retention ecosystem that drives measurable revenue — without you having to think about it daily. Most Shopify store owners lose revenue not because their products are weak — but because their Klaviyo setup is incomplete, their flows are disconnected, their list hygiene is poor, and their segmentation isn't built around actual customer behavior. Abandoned carts are lost, post-purchase upsells aren't firing, winback sequences are missing, and deliverability is silently killing open rates. I solve that by building conversion-focused Klaviyo systems designed around customer lifecycle marketing, retention strategy, and revenue optimization — with always-on A/B testing and weekly performance tracking built in. 🚀 What I Can Help Your Brand With ✔ Klaviyo Email Marketing Strategy & Full Account Setup ✔ Klaviyo Flow Architecture, Optimization & Audit ✔ Email + Klaviyo SMS Marketing Integration ✔ Campaign Calendar Management (Promotional, Seasonal, Product Launches) ✔ Advanced Customer Segmentation & Audience Targeting ✔ Welcome Series, Abandoned Cart & Browse Abandonment Flows ✔ Post-Purchase, Upsell & Replenishment Flows ✔ Winback, Re-Engagement & Sunset Flows ✔ Shopify + Klaviyo Integration & Flow Automation ✔ List Hygiene, Deliverability Optimization & Suppression Strategy ✔ A/B Testing (Subject Lines, Send Times, Offers, CTAs) ✔ Revenue-Focused Email Copywriting & Brand Voice ✔ High-Converting Email Template Design (Mobile-Responsive) ✔ Figma to Klaviyo Email Design & Implementation ✔ Performance Reporting (Open Rate, CTR, Revenue Attribution) ✔ Zapier & Make Automation Workflow Integration 💡 What Makes My Approach Different I don't just build emails. I build complete retention and lifecycle marketing ecosystems inside Klaviyo engineered around customer psychology, segmentation logic, conversion timing, and revenue growth. ✔ Every flow has a clear, quantifiable revenue goal ✔ Every automation is built to increase LTV and repeat purchase rate ✔ Every campaign is tied to performance metrics — not just opens and clicks ✔ Every decision is data-informed and supported by numbers I work autonomously and proactively. I don't need daily direction. I monitor performance, flag issues early, and bring proactive recommendations whether that's a new flow, a deliverability issue, or a list health problem driving up your Klaviyo bill. 🎯 Who I Work Best With Whether you run a Shopify store, DTC health brand, beauty or skincare brand, wellness or supplement brand, subscription business, or fashion brand — I help you build a system where new subscribers become paying customers, abandoned carts turn into recovered revenue, one-time buyers become repeat customers, and your email list becomes one of your most profitable business assets. 📊 Why This Matters Your competitors aren't winning because they have better products. They're winning because they have smarter lifecycle marketing systems, stronger retention strategies, better segmentation, cleaner lists, and a dedicated operator who ties every decision back to revenue. 👉 Send me a message and let's build a conversion-focused email and SMS retention system that actually works.

I specialise in large-scale web research and structured data collection, helping founders, teams, and growing companies build accurate, reliable datasets they can actually use. As a Web Research & Data Collection Specialist, I’ve delivered projects across industries including tech, aviation, culture, and consumer markets.

Beyond research, I bring experience as a Startup Generalist and Product Operations Coordinator. I’ve supported founders, managed interns, and set up internal systems and documentation that help early-stage teams operate with clarity. That said, my primary focus here is delivering high-quality research and data at scale.
