Klaviyo Retention Expert | Email, SMS & CRM Growth

📈 Turn First Time Buyers Into Repeat Revenue Most Shopify brands focus heavily on acquiring customers. The brands that scale profitably focus on keeping them. I'm a Retention & CRM Consultant specializing in Klaviyo, email marketing, SMS marketing, and lifecycle marketing for DTC ecommerce brands. I help Shopify businesses transform retention from an afterthought into a predictable revenue channel that increases repeat purchase rates, customer lifetime value, and profitability. Unlike many consultants who stop at strategy, I work strategy through execution. I diagnose the retention engine, architect the solution, and either build it myself or oversee implementation to ensure it performs. Currently, I lead retention marketing in-house for a premium DTC fashion brand generating £30M+ annually across four Shopify storefronts in the UK, US, EU, and Australia. 🚀 What I Help Ecommerce Brands Achieve If your brand has an email list but isn't generating the revenue it should, I can help you: ✅ Increase repeat purchase rates ✅ Improve customer lifetime value (LTV) ✅ Reduce reliance on discounting ✅ Strengthen loyalty and retention programs ✅ Improve email deliverability and list health ✅ Build scalable lifecycle marketing systems ✅ Understand customer behavior through retention analytics 📧 Klaviyo & Lifecycle Marketing I design and optimize the systems that turn customers into repeat buyers: • Klaviyo audits and account rebuilds • Email and SMS lifecycle flow architecture • Welcome series • Abandoned checkout flows • Browse abandonment flows • Post purchase journeys • Replenishment campaigns • Winback sequences • VIP customer programs • Sunset and re-engagement flows • Campaign planning and execution • Customer segmentation and suppression logic • List growth strategies and lead capture systems • Deliverability optimization and sender reputation management 🛍️ Shopify Retention & CRM Strategy Beyond email and SMS, I help brands build a complete retention ecosystem: • Klaviyo and Shopify integration setup • ESP migrations into Klaviyo • Loyalty program design and optimization • LoyaltyLion implementation • Customer retention strategy • Returns reduction and post-purchase optimization • Martech stack evaluation and rollout • Customer experience improvement initiatives 📊 Customer Research, Analytics & Forecasting Retention isn't guesswork. I help brands make smarter decisions using data: • Cohort analysis • Customer lifetime value analysis • Revenue forecasting • Repeat purchase modeling • Contribution margin analysis • CAC and break-even modeling • NPS and customer segmentation • Survey design and analysis • Voice of Customer research • Stakeholder-ready reporting and recommendations 🏆 Recent Results 📈 Rebuilt a DTC wellness technology brand's Klaviyo account across English and German markets, increasing flow revenue by 3.5x within the first 30 days. 📈 Led the redesign of a multi-store LoyaltyLion program for a £30M+ fashion brand after identifying misaligned reward economics and low customer awareness. 📈 Built and optimized 30+ interconnected lifecycle flows across four international Shopify storefronts using advanced segmentation and suppression logic. 📈 Delivered large-scale customer research programs involving 6,000+ survey respondents, transforming customer feedback into actionable retention strategies. 🎯 Who I Work Best With I typically partner with Shopify brands generating $500K+ in revenue, particularly within: • Fashion & Apparel • Beauty & Skincare • Wellness • Food & Beverage • Coffee • Lifestyle Brands • Consumer Products These businesses usually have a customer base, an email list, and growing traffic, but lack the retention systems needed to maximize customer value. 🤝 How I Work Whether you need a one-time Klaviyo audit, a complete retention rebuild, or ongoing fractional retention leadership, my focus remains the same: Turn retention into a measurable, compounding growth channel that drives repeat revenue and long-term profitability. If you're ready to get more value from the customers you've already paid to acquire, let's talk.
