About Tiny Health

Tiny Health is the first precision microbiome intelligence platform dedicated to helping every person start — and stay — healthy for life.

We’ve built an AI-powered engine to train our platform with the latest scientific research on top of our proprietary bioinformatics pipeline leveraging shotgun metagenomics.

Trusted by +150,000 customers and +5,000 practitioners, Tiny Health’s mission is to make the microbiome measurable, accessible, and actionable at every life stage, from birth through healthy aging. Our vision is to build a world where chronic conditions are prevented and course-corrected through evidence-based microbiome interventions.

The Opportunity

We’re hiring a Lifecycle Marketing Manager to own the entire customer journey — from the moment someone discovers Tiny Health through member retention. This is a high-impact, high-ownership role at the intersection of strategy and execution. Email and SMS are your primary channels, but you’ll also shape how we use direct mail, in-app messaging, and other touchpoints to keep our customers engaged, drive repeat purchases, and deepen their relationship with Tiny Health over time.

You’ll collaborate closely with our growth, content, and product teams, and take full ownership of our lifecycle agency relationship, setting direction and holding them accountable to performance.

Responsibilities

Lifecycle Strategy

• Build and evolve Tiny Health’s end-to-end lifecycle strategy across the full customer journey from activation through retention, upsell, and win-back
• Develop segmentation frameworks that account for product line (baby, child, adult gut health, vaginal health, and Tiny+ memberships), test results, and member behavior
• Manage distinct lifecycle journeys for our two core audiences: parents focused on infant and early childhood gut health, and adults seeking digestive health insights
• Identify and close gaps in the current program: segmentation depth, testing cadence, content quality, and performance
• Partner with the growth team to connect lifecycle programs with acquisition insights and conversion data

Email and SMS Program Execution

• Own all lifecycle email and SMS end-to-end flows, campaigns, promotions, and transactional sequences built and managed in Klaviyo
• Leverage Shopify and Recharge data to power segmentation, trigger-based flows, and subscription lifecycle programs (trials, renewals, cancellation saves)
• Write, brief, and QA email copy in Tiny Health’s brand voice; partner with our copywriter for larger campaigns
• Own deliverability, list health, and ESP hygiene, and more

Analytics, reporting & testing cadence

• Build and launch a lifecycle performance dashboard that surfaces weekly optimization signals across list growth, flow performance, and campaign revenue, establishing the data infrastructure this role runs on
