Responsibilities

• The Retention Marketing Manager owns BRUNT’s lifecycle marketing program across our owned channels, SMS and Email, building the flows and segmentation logic that move customers through the full lifecycle: from list growth (including on-site acquisition) through first purchase, repeat purchase, and long-term loyalty. You architect multi-step, conditional customer journeys with D2C revenue, repeat behavior, and customer lifetime value (LTV) as your north star metrics. You’re also responsible for the broader health of these channels: deliverability, audience growth, engagement, and conversion.
• Channel Management
• - Lead the hands-on build of SMS and Email flows directly in Klaviyo & Postscript, partnering with the Email Marketing Associate and creative team on execution and QA.
• - Act as BRUNT’s subject matter expert in SMS and Email, tuning our campaign calendar to prioritize the campaign types that consistently drive revenue and brand engagement.
• - Be an authority on copy and design, leveraging past performance data to back decisions, and running a thoughtful A|B testing program across campaigns to continuously optimize on a monthly basis.
• - Run thoughtful A/B tests in Email/SMS flows (welcome, post purchase) that impact BRUNT’s key objectives. Regularly track and maintain A/B test results and report out on performance internally.
• - Build and maintain advanced customer segments from behavioral, transactional, and lifecycle data (RFM, purchase history, engagement, product/category affinity) to power segment-specific messaging.
• Platform & Data Management
• - Serve as the in-house Klaviyo & Postscript expert, owning flow architecture, list/segment hygiene, and deliverability configuration without relying on outside developers or agencies.
• - Understand how customer and order data moves between systems (Shopify, Klaviyo, Postscript, Rivo) - custom properties, events, and integration syncs — and troubleshoot when data or triggers break.

Requirements

• 2-3+ years of hands-on retention/lifecycle marketing experience, with demonstrated ownership of building (not just briefing) Email and SMS programs
• Deep, hands-on expertise in Klaviyo & Postscript (or a comparable ESP/SMS provider such as Attentive, Iterable, or Braze) - you can independently build and debug complex, multi-step flows, including conditional splits/if-then branching logic, dynamic content, and API-based triggers, without relying on a developer
• Comfortable writing basic HTML/CSS and Liquid templating logic (if/else conditional blocks) to personalize content within a single template
• Strong Excel skills - comfortable building pivot tables, blending data from multiple exports, and turning raw performance data into clean reports and dashboards for leadership
• Strong command of customer segmentation and data: comfortable building dynamic segments from behavioral and transactional data (RFM, LTV, purchase/engagement history) and mapping them to differentiated content paths
• Familiarity with data integrations between an ESP/CDP and ecommerce platforms (Shopify) - custom properties, event tracking, and basic troubleshooting when syncs or triggers break; SQL or other data-querying skills a plus
• Experience with A|B testing
• Adept in strategic thinking & analytics with a passion for innovation and creative problem solving (familiarity using tools such as Google Analytics, Looker a plus)
• Demonstrated ability to excel in a demanding and ambiguous environment with competing priorities
• Ability to commute to the office in North Reading, MA 4X per week
