Growth Marketing Manager

About WellTheory

WellTheory is a digital health company helping people with autoimmune conditions take control of their health through personalized care, nutrition guidance, and ongoing coaching. We're a team of 50+ passionate people who believe better care starts with better relationships. We're also building one of the most AI-forward organizations in healthcare — not by replacing our team with AI, but by expanding what every person here is capable of.

About The Role

This role sits at the center of WellTheory's B2C side of its B2B2C model, partnering with employers and health plans to give their members access to best-in-class autoimmune care. Your primary mandate is to unlock the performance of email and direct mail channels, which drive the vast majority of our member enrollments. You'll be working closely with our Head of Marketing to sharpen our strategy, build more rigorous testing frameworks, and push the quality and performance of our core channels meaningfully higher. You'll be trained and supported throughout, and you'll bring enough channel expertise to operate independently once you're up to speed.

What You'll Do

• Email & Direct Mail
• Own the strategy and optimization of WellTheory's email and direct mail programs — our two highest-volume enrollment channels
• Drive performance through segmentation, personalization, creative testing, and sequencing improvements
• Design and run structured experiments: from hypothesis, establishing a baseline, estimating an expected delta, and establishing clear KPIs
• For direct mail: test formats and creative, and track response rates rigorously
• For email: own campaign strategy, segmentation, an A/B testing roadmap, and lifecycle flow architecture
• Integrate offline (direct mail) and online (email, SMS) channel strategies into a cohesive member journey
• Growth Strategy & Funnel Optimization
• Analyze the end-to-end enrollment funnel, identify drop-off points, and develop clear recommendations for optimizations — then execute on them
• Monitor all performance data daily and weekly; be one of the first people to know when something breaks or something's working
• Design and run structured experiments: from hypothesis, establishing a baseline, and establishing clear KPIs
• Conduct user research to understand who WellTheory's members are, what motivates them to enroll, and what keeps them engaged and translate those insights into smarter targeting, sharper messaging, and better product marketing
• Client & Stakeholder Work
• Partner with employer and health plan clients to support successful member enrollment — including responding to client communications and creating one-pagers and enablement materials
• Present performance, insights, and recommendations to senior leadership clearly and with conviction
• Team Operations
• Help keep the marketing team's Asana organized and up to date as it relates to email and direct mail campaigns

Our AI Philosophy

We believe AI is now a role requirement in every discipline, not just engineering. We expect you to use AI to streamline operations, reduce busywork, and give yourself more time to think about what's most important. That said, we don't expect you to use AI to replace taste or judgment. WellTheory's care model is centered on human-to-human connection, and that human touch is core to our marketing as well. No AI slop! We want someone who knows when to use it and when to put it down.

What We Offer

• The chance to define WellTheory's AI transformation from the ground up — with a founding team that is bought in, a company that is already ahead of most, and real urgency to go further
• A direct partnership with the co-founders and Staff leadership team
• A team that's already building in AI — you're accelerating something with momentum, not convincing skeptics
• Competitive compensation, benefits, and remote work
• A base salary range of $120,000 - $135,000 with meaningful equity and benefits. Placement within our range depends on directly relevant skills and experiences you bring to the role
