Senior Lifecycle & Retention Marketing Manager (Ecommerce & Membership)

We are ARB Interactive, the team behind Modo Casino, one of the top Social+ platforms in the US. Founded in 2022, we've grown to nearly 200 team members and were named one of LinkedIn's 2025 Top 50 Startups in the United States. We move fast, think big, and love bold ideas that push boundaries (and buttons). From new rewards to fresh game mechanics, every challenge is a chance to innovate and have fun doing it. Our culture is collaborative, curious, and full of laughter because great ideas grow best between coffee, code, and a few epic high-fives.

About PCH

PCH runs a growing commerce, membership, and sweepstakes platform. Customers engage with us across shopping, membership, rewards, and sweepstakes, which gives us a lot of room to build personalized customer journeys. Lifecycle marketing is one of the main ways we grow conversion, repeat purchase, membership, and lifetime value.

Role Summary

You’ll own lifecycle and retention marketing across email, SMS, and membership communications. You’ll do both the strategy and the hands-on work. You’ll own the full customer journey, from registration and first purchase through membership, repeat purchase, retention, and win-back. Do they make a first purchase? Become a member? Buy again? Stay? Come back after lapsing? Email and SMS are large revenue drivers, and this role is accountable for growing that revenue. We measure this role by those outcomes, not by sends, opens, or clicks.

What You’ll Do

• Own the lifecycle roadmap. Find the biggest opportunities across the customer journey and bring them to the team, rather than waiting for someone to hand you a brief.

• Lead PCH’s move to Klaviyo by building our lifecycle program and core flows from the ground up.

• Build and optimize automated flows directly in Klaviyo. That includes trigger and event logic, segmentation, entry/exit and suppression rules, coordinating email and SMS, and personalization.

• Build behavior-based segments by lifecycle stage, purchase history, membership status, engagement, and customer value.

• Run membership programs: onboarding, benefit adoption, churn prevention, cancellation, win-back, and upgrades.

• Partner with Paid UA to turn customer data into Meta audiences and to align what new users experience from ad click to first purchase.

• Run a steady testing program. Every test starts with a hypothesis and a target KPI, and ends with documented learnings and a next step.

• Own the campaign calendar and QA process, especially during high-volume promotional periods and sweepstakes deadlines.

• Own lifecycle reporting. Connect CRM activity to revenue, conversion, repeat purchase, retention, churn, reactivation, and LTV.

In Your First 90 Days

You’ll audit our current lifecycle and Klaviyo setup and map the customer journey. You’ll also set baseline KPIs, launch or improve the highest-priority evergreen flows, and show measurable progress on at least one major conversion or retention metric.

What You Bring

• 7+ years in lifecycle, CRM, or retention marketing, including owning a lifecycle program end to end

• Deep hands-on Klaviyo experience, including building complex flows from strategy through implementation

• Experience leading a CRM/ESP migration or building a Klaviyo program from scratch

• Email and SMS experience in an ecommerce and/or subscription/membership business

• A track record of measurably improving retention, repeat purchase, conversion, churn, or LTV

• Proven revenue impact. You can point to lifecycle programs you built that measurably grew revenue.

• Strong analytical skills and experience running structured A/B tests

• Shopify or Shopify Plus experience

• Excellent attention to detail and QA discipline

• The ability to work independently and drive your own priorities

Nice to Have
Experience in sweepstakes, rewards, loyalty, or promotional ecommerce. Experience with membership platforms such as Appstle, Skio, or Recharge.

This Role Is Not
A newsletter or email production role, or a strategy-only role that hands implementation to agencies. This is an ownership role.
