Senior Lifecycle Marketing Manager - French-Speaking @ Sinch

Sinch is a global leader in cloud communications, helping businesses connect with their customers through messaging, voice, and email. Our platform powers billions of interactions every year - from transactional alerts and marketing campaigns to rich, AI-driven conversations.

We're at an inflection point. As enterprise communication shifts from one-way messaging to intelligent, multi-turn conversations, Sinch is building the products and infrastructure that will define this next chapter. That means investing in agentic AI, conversational intelligence, and the orchestration layer that ties it all together.

Sinch is looking for a Senior Lifecycle Marketing Manager to join the Mailjet marketing team and own lifecycle marketing for our growing global customer base.

Your mission is

build and run a scalable lifecycle program that moves customers from Free to Paid, from lower to higher plans and on to contract, and keeps them from downgrading or churning. You'll build it AI-first, using agents and automation to multiply what one person can do. This role is for a hands-on lifecycle marketer who builds journeys themselves and is strategic enough to decide which ones matter. You'll have the autonomy to define your approach and full ownership of lifecycle performance.

You will be accountable for: drive activation by helping new accounts achieve their first successful send, free-to-paid conversion, plan upgrades and add-ons and downgrades, churn and revenue retention.

• Identify sales-ready accounts and opportunities to drive adoption of complementary Sinch solutions, including SMS and WhatsApp.
• Define and own lifecycle performance metrics, reporting frameworks and measurement strategies, demonstrating the impact of lifecycle initiatives on revenue.
• Continuously experiment, test and optimize customer journeys, scaling what works and challenging what doesn't.
• Leverage customer, product and behavioral data to identify opportunities, anticipate customer needs and deliver actionable insights to Product, Growth and Engineering.
• Build and implement AI-powered workflows and agents to accelerate journey creation, localization, personalization and quality assurance, ensuring appropriate human oversight.
• Leverage AI to deliver account-level personalization and identify predictive signals for customer engagement, churn risk and expansion opportunities.
• Prototype new AI-powered tools and workflows, and share best practices to drive AI adoption across the organization.
• Ensure all lifecycle initiatives comply with GDPR, internal data policies, brand guidelines and email deliverability best practices.
• Collaborate cross-functionally with Product, Growth, Engineering, Product Marketing, Customer Success, Support, Sales and Finance to deliver a consistent and impactful customer experience.
• Develop and localize lifecycle strategies and customer experiences across Mailjet’s core markets: France, Germany, Spain, the UK and the US.

About you

• 5+ years of lifecycle, retention or growth marketing in B2B SaaS, ideally freemium or product-led.
• A track record of lifting activation, conversion, upgrades or retention, with numbers to show for it.
• Experience with experimentation, customer research and behavioral data; comfortable pulling your own data (SQL a plus).
• AI tools and agents are part of your daily work today, and you can show what changed because of it.
• Marketing automation platforms (e.g. Salesforce Marketing Cloud, Braze, Customer.io), in-app tools (e.g. Gainsight PX, Pendo) and product analytics.
• Experience migrating a lifecycle program between platforms is a strong plus.
