About The Position

Sinch is looking for a Senior Lifecycle Marketing Manager to ensure Mailgun customers don't just sign up—they actively adopt, engage with, and extract ongoing value from our platform. As the global owner of Mailgun's lifecycle marketing strategy, you will define and execute the strategy for moving self-serve users from signup through activation, paid conversion, and long-term engagement. This role is focused on driving user activation, deepening product engagement, and maximizing customer lifetime value through data-driven lifecycle programs that directly support business growth. The ideal candidate brings deep experience in lifecycle marketing, onboarding optimization, and user retention strategies within a B2B SaaS product-led growth (PLG) environment. You obsess over cohort retention curves, understand the psychology of behavior change, and know how to design, optimize, and evolve engagement experiences that drive meaningful customer and business outcomes.

Requirements

• 5+ years of experience leading lifecycle marketing initiatives within a B2B SaaS organization, ideally in a product-led growth (PLG) subscription business.
• Proven success building and optimizing lifecycle programs using experimentation, customer insights, and data to improve activation, conversion, and retention.
• Strong project management and prioritization skills, with the ability to independently balance multiple initiatives and drive them to completion.
• Experience partnering with cross-functional teams, including Product, Growth, Marketing, Customer Success, and Engineering, to deliver customer-focused outcomes.
• Excellent written and verbal communication skills, with the ability to translate customer insights and data into actionable recommendations.
• Experience with lifecycle marketing platforms, in-app messaging tools (such as Gainsight), marketing automation platforms, and product analytics tools.

Responsibilities

• Design, build, and continuously evolve lifecycle experiences across email, in-app messaging, and other customer touchpoints that help users realize value faster and move confidently from signup to paid.
• Identify customer-journey friction that cannot be solved through lifecycle messaging alone, develop evidence-based recommendations, and drive prioritization and execution with Product, Growth, Engineering, Marketing, and Customer Success.
• Audit Mailgun’s existing lifecycle programs and independently prioritize, redesign, retire, or build journeys based on performance.
• Establish the lifecycle measurement framework, use performance and product-usage data to identify opportunities, and own optimization of activation, conversion, engagement, retention, and attributed revenue.

Benefits

• Comprehensive market competitive medical, dental, and vision plans.
• Variety of supplemental plans.
• Access to telehealth for all participants.
• Free virtual counselling resources through our global Employee Assistance Program.
• Roth and Pre-tax 401(k) options including an employer match.
• Generous paid time off program.
• Paid parental leave and family planning support.
• Paid time off to support a volunteer program of your choice.
