Senior Manager, Lifecycle Marketing, Mail

Superhuman is an AI productivity platform on a mission to unlock the superhuman potential in everyone. They are seeking a Senior Manager, Lifecycle Marketing to own the lifecycle strategy and execution for the Superhuman Mail business unit, focusing on user activation, engagement, retention, and expansion through scalable programs.

Responsibilities:

• Own lifecycle strategy for Superhuman Mail (0→1 and scale) by defining and building end-to-end lifecycle across onboarding, activation, engagement, self serve team creation, expansion, retention, and win-back — including identifying key user moments, lifecycle gaps, and growth levers
• Build lifecycle foundation. Establish core systems including segmentation frameworks, lifecycle architecture, experimentation strategy, and KPI definitions (activation, engagement, retention, LTV)
• Design and optimize cross-sell and expansion journeys across Grammarly, Coda, and Superhuman Mail — including audience prioritization, messaging strategy, and journey orchestration
• Design A/B and holdout experiments, define incrementality frameworks, and translate insights into clear product and marketing recommendations
• Build best-in-class lifecycle programs across email and in-product messaging — balancing scale, personalization, and user experience
• Work closely with Product, PMM, Data/Analytics, and Marketing Ops to align lifecycle with product surfaces, growth loops, and business goals

Requirements:

• 6–10 years of experience in lifecycle marketing — or a closely related function like growth — at a consumer technology, SaaS, or product-led growth company
• Proven ability to build lifecycle programs from scratch; has owned 0→1 program development, not just optimized established playbooks, and brings structure to ambiguity
• Deep expertise in lifecycle program execution across email and in-product messaging, with end-to-end ownership from strategy through measurement; Iterable experience strongly preferred
• Strong experimentation acumen: designs scientifically sound A/B and holdout experiments, understands incrementality measurement, and can draw accurate conclusions in complex multi-holdout environments
• Experience in cross-sell or multi-product lifecycle marketing — has designed programs that move users from one product into an adjacent one, or can reason clearly about cross-sell audience identification and journey design
• Expert-level segmentation skills — builds nuanced audience strategies based on behavioral, demographic, and inferred data; understands the difference between a broad segment and a precise one, and when each is appropriate
• Data-driven decision making: can pull their own data, build simple reporting, and form hypotheses without waiting for a data pull; partners effectively with Data Science and knows when directional insight is sufficient vs. when precision matters
• Cross-functional fluency — navigates PMM, Data Science, Marketing Ops, and Business Unit partners effectively; builds trust quickly and can unblock themselves without unnecessary escalation
• Values a data-informed, experiment-oriented working style, embraces continuous improvement, and aligns with our Superhuman values
• Has a demonstrated ability to work autonomously with minimal oversight, proactively manages tasks and priorities across multiple projects, analyzes and executes work efficiently, collaborates effectively with cross-functional teams, and thrives in fast-paced, results-oriented environments
