Turning inboxes into revenue engines.Sergei Vasilev
I help DTC and lifestyle brands turn their CRM and email marketing into measurable growth engines. By combining strategic lifecycle design with hands-on execution in Klaviyo, Shopify, and GA4, I build automated systems that drive retention, repeat purchase, and long-term customer value. What makes me different is the blend of brand-level experience (Adidas, Reebok, Goorin Bros.) and data-driven precision — every flow, segment, and campaign is designed to perform, not just send.
