Job description

We’re looking for a hands-on CRM & Retention Manager to own retention at SIZZ and turn more first-time customers into loyal, repeat customers.

This is not a strategy-only role. You’ll own retention end-to-end and work directly in Klaviyo, building the flows, campaigns, segments, experiments and reporting yourself.

Your mission is clear: increase repeat purchase rate and customer lifetime value, while growing CRM revenue without relying heavily on discounts.

What you’ll own

• Klaviyo strategy and hands-on execution
• First-to-second purchase conversion
• Lifecycle flows and automations
• Email campaign strategy and calendar
• Customer segmentation and personalization
• Winback and reactivation
• Customer retention and LTV
• A/B testing and experimentation
• Cohort and customer behaviour analysis
• Loyalty and VIP initiatives
• Reporting on what is actually driving repeat revenue

Who we’re looking for

You’ve worked hands-on with 7 or 8-figure DTC/e-commerce brands and know how to turn customer data into repeat revenue.

You:

• Have experience with brands doing €1M–€10M+ in annual revenue
• Have personally built and optimised high-performing flows and campaigns
• Understand retention, lifecycle marketing, segmentation and LTV
• Know how to improve the journey from first purchase to second purchase
• Are analytical and commercially minded
• Think beyond open rates, clicks and attributed email revenue
• Can identify why customers aren’t coming back and turn those insights into action
• Test constantly, learn quickly and use the results to decide what comes next
• Take ownership and move fast

Fashion experience is strongly preferred.

We’re looking for someone who has already seen what great retention looks like at scale. Someone who can find the opportunity in the data, build the solution in Klaviyo, launch it, measure the impact and keep improving it.

What we offer

• Performance-based bonus
• Ownership over one of our biggest sales channels
• A fast-moving DTC fashion environment
• The opportunity to directly influence retention strategy and customer LTV

English required. Dutch is optional.

Interested?

If you’ve personally helped improve retention at a 7- or 8-figure DTC brand, we want to hear from you.

When applying, show us what you’ve done. Share the brands you’ve worked with, what you personally owned and the measurable impact you had on repeat purchase rate, LTV or CRM revenue.

We’re looking for an individual who wants to take ownership of retention as part of our team.
