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 60+ passionate people who care deeply about helping our members reduce symptoms, feel better, and live fuller lives — while helping employers and payors reduce their spend.

The Role

Help us bring WellTheory’s marketing campaigns to life.

In this hands-on role, you’ll build and QA email and direct mail sends, pull clean performance data, and use what you learn to make each campaign better than the last. You’ll work side by side with our full-time Marketing Technology and Operations Lead, so every detail is covered and nothing slips through the cracks.

This role is for you if you enjoy the space where operations, project management, and data meet, and you want your work to help people live healthier, more empowered lives.

About you

These aren’t requirements. You don’t need to check every box. If this sounds like you, we’d love to hear from you.

You’re a campaign pro who brings precision to everything you touch, from inboxes to mailboxes. You move easily between tools like Customer.io and PostHog to deliver reliable performance data.

• 4+ years (or equivalent experience) building, QA’ing, and deploying email campaigns in platforms like Mailchimp, Iterable, and ActiveCampaign

• A sharp eye for detail: you catch the missing comma or dead link before it reaches an audience

• Experience on cross-functional, remote teams, and clear communication with marketers, designers, and developers

• Strong organizational skills. You’re not a project manager, but you think like one, planning a few steps ahead and delivering on time.

• A growth mindset and comfort with shifting priorities

• Ease pulling and organizing performance data across multiple platforms

Nice To Have

• Deep expertise in HTML and CSS for email development (to translate our Design team's incredible mocks into incredible emails!)

Who We’re Looking For

Outside of the specific role, here are qualities that make someone successful at WellTheory:

• Empathy for the autoimmune experience. You don’t need a personal autoimmune condition, but you care deeply about the lived experience of patients and can share it with others.

• Beginner’s mindset. You love learning, ask questions freely, own your mistakes, and stay open to new ways of solving problems.

• Persistence.You keep going when things get hard, whether that’s running a marathon, starting a company, earning a degree while working full-time, or getting through real adversity.

What You’ll Do

• Build, QA, and deploy on-brand email campaigns in Customer.io

• Maintain and segment marketing lists so targeting stays accurate

• Place and manage direct mail orders with our vendor, on time and error-free

• Own QA for email and direct mail proofs, so every piece meets our brand standards

• Create and manage redirects and tracking URLs for end-to-end campaign measurement

• Pull and combine campaign metrics from Customer.io and PostHog

• Deliver clear, accurate reports that help the team improve over time

• Bring curiosity and creativity to finding new ways to streamline workflows, deepen personalization, and sharpen reporting using AI

Details

• Location: Remote

• Role type: Part-time, hourly contract role (~15-20 hours per week)

• Flexible schedule

• Reports to: Head of Marketing
