Sophia Müller is an Email Marketing & Conversion Strategist with a proven track record of building email programs that generate measurable revenue. Over her 9+ year career in B2B and B2C email strategy, she has managed campaigns that generated over $40 million in directly attributable revenue across SaaS, e-commerce, and financial services verticals. Sophia's email philosophy is data-first: every subject line, send time, content block, and CTA should be testable, measurable, and optimizable. This approach made her an early and enthusiastic adopter of AI-powered email personalization, which she sees as the natural evolution of the data-driven methodology she's practiced throughout her career. Her career began in management consulting at Bain & Company, where she worked on customer retention and loyalty programs for major retail brands. Discovering that email was consistently the highest-ROI channel for retention, she pivoted to specialize in email marketing. She spent 4 years at a leading email service provider, working directly with enterprise clients to optimize their email programs and develop best practices that were later published as industry benchmarks. Before joining YOYA, Sophia led the email and lifecycle marketing team at a Series C SaaS company, where she implemented AI-driven personalization that increased email revenue per subscriber by 340% over 12 months. Her key insight: the biggest ROI in AI email isn't in writing better subject lines—it's in delivering the right message to the right person at the right moment in their customer journey. Sophia is a recognized thought leader in email marketing, with bylines in MarketingProfs, Email on Acid, and Really Good Emails. She's a certified Salesforce Marketing Cloud consultant and HubSpot Email Marketing certified professional. She holds a B.S. in Economics from the London School of Economics and an MBA from INSEAD. Outside of work, Sophia is a classical pianist, amateur sommelier, and advocate for women in marketing technology.
