Job description
About THRIVIN
THRIVIN is building the uniform for disciplined women.
We create premium performance gymwear designed for women who train with intent and expect more from themselves and from what they wear.
We are not building a brand people buy from once.
We are building a brand customers come back to, again and again.
Retention is not a support function.
It is a core growth driver.
The Role
We’re looking for a Retention Manager to own execution across CRM and lifecycle marketing.
This is a high-ownership, performance-driven role focused on driving repeat revenue and customer lifetime value.
You will manage and execute across email, SMS, and lifecycle — building systems that bring customers back consistently.
This is not just about sending campaigns.
This is about building a retention engine that compounds over time.
What You’ll Be Doing
Retention Execution
- Own and manage all CRM channels (email, SMS, lifecycle)
- Execute weekly campaigns, launches, and promotional calendars
- Ensure all campaigns are delivered on time and to a high standard
Lifecycle & Flows
Build and optimise high-performing flows, including:
– Welcome series
– Abandoned cart and checkout
– Post-purchase journeys
– Win-back and reactivation
- Continuously improve flows based on performance data
Copy & Creative
- Write high-converting copy for campaigns and flows
- Test hooks, angles, and offers
- Maintain a consistent, premium brand voice
Performance & Optimisation
Track and improve key metrics:
– Revenue per recipient
– Repeat purchase rate
– Customer lifetime value
- Use data to continuously test, iterate, and scale what works
Collaboration
Work closely with:
- CRM Strategy Lead → direction and priorities
- Design team → creative execution
- Performance team → alignment with paid activity
- Act as the execution partner to the CRM Strategy Lead
What We’re Looking For
- 2–5+ years experience in CRM / retention marketing
- Strong copywriting skills with a focus on conversion
- Hands-on experience with Klaviyo
- Data-driven mindset with strong analytical ability
- Experience with segmentation, testing, and optimisation
- High ownership and ability to execute independently
- Strong understanding of customer behaviour and lifecycle marketing
- Affinity with fitness, wellness, or gym culture
- Fluent in English
Ideal Candidate
- You think in terms of revenue, not just sends
- You understand how to turn first-time buyers into repeat customers
- You are both creative and analytical
- You move quickly, test often, and improve constantly
- You take ownership and deliver without needing oversight
What Success Looks Like
- Retention becomes a key revenue driver
- Flows and campaigns consistently perform and improve
- Repeat purchase rate increases over time
- Customers stay engaged with the brand
- CRM becomes a predictable, scalable growth channel
Why Join THRIVIN
- Own a critical growth channel end-to-end
- Be part of a fast-growing global brand
- Work in a high-performance, results-driven team
- High ownership, fast execution, real impact
Location
United Kingdom (Remote)
