Sr. Lifecycle & Retention Marketing Manager

LettrLabs•Los Angeles, CA

3d•$150,000 - $170,000•Onsite

About The Position

LettrLabs helps companies automate direct mail the same way they automate email — triggered, personalized, and measurable. Our customers use us to win back churned subscribers, convert trial users, re-engage dormant accounts, and drive repeat purchases. The lifecycle engine is already working. Now we need someone to own it end-to-end. As our Senior Lifecycle & Retention Marketing Manager, you'll own the complete customer journey — starting before someone becomes a customer and continuing through activation, retention, and expansion. You'll build the programs that convert leads who haven't purchased yet, onboard new customers to first value fast, move monthly subscribers to annual plans, and drive expansion revenue without requiring sales to initiate every conversation. This role is a meaningful revenue lever, not a support function.

Requirements

4–8 years in lifecycle, retention, or CRM marketing in a B2B SaaS environment — with ownership of both pre-purchase nurture and post-sale programs (highest priority; post-sale only backgrounds will not be considered).
Hands-on experience building and managing automated programs in HubSpot, Marketo, Customer.io, or a comparable marketing automation platform — you build the workflows yourself, not just direct someone else to.
Demonstrated ability to connect lifecycle programs to revenue outcomes: conversion rates, retention rates, NRR, expansion ARR, or churn reduction — with numbers to back it up.
Strong segmentation instincts: you know how to use behavioral data, firmographics, and lifecycle stage to send the right message to the right person at the right time.
Analytical enough to own your own reporting — you can build a dashboard, interpret cohort data, and make program decisions without waiting for a data team.
Strong written communication: you write clear, on-brand copy for emails and direct mail without heavy editing support.
Comfortable operating independently in a fast-moving environment where priorities shift and you're building infrastructure that doesn't yet exist.
Must be willing to work on-site regularly in at our office in Culver City

Nice To Haves

Experience using direct mail as a lifecycle channel alongside email — or curiosity to build that motion from scratch.
Background in home services, e-commerce, or SMB-focused B2B SaaS audiences.
Experience with multi-channel attribution and revenue influence modeling.
Familiarity with product analytics tools (Mixpanel, Amplitude, or similar) to inform lifecycle trigger logic.

Responsibilities

Own the full customer lifecycle from pre-purchase nurture through activation, retention, and expansion — this role covers the entire journey, not just post-sale.
Build and manage automated nurture sequences for leads who haven't converted yet — email, in-app, and direct mail flows that move prospects to first purchase without sales intervention.
Design and own onboarding programs that get new customers to first value fast, measurably reducing time-to-activation.
Build retention and expansion programs that move customers from monthly to annual plans and drive upsells — reducing sales' dependency on owning every expansion conversation.
Develop win-back and re-engagement programs for churned or dormant accounts.
Build audience segmentation frameworks across customer types, verticals, and lifecycle stage to enable relevant, personalized messaging at scale.
Partner with Customer Success to identify at-risk accounts early and build intervention programs before accounts churn.
Own lifecycle reporting and attribution — activation rates, conversion rates, NRR impact, and revenue influenced across all programs.
Manage the marketing automation stack for lifecycle execution: HubSpot, customer data, segmentation tools, and the LettrLabs platform itself.
Run structured A/B tests across subject lines, send cadences, channel mix, and content to continuously improve performance.
