Retention Marketing Manager in London

Are YOU the Retention Marketing Superhero We're Looking For?

Who are you?

• You're a commercially minded retention marketer who loves seeing numbers move because of what you shipped.
• You're just as comfortable building and improving email and SMS flows as you are planning promotional campaigns, reviewing performance, and asking: "How do we get more value from the customers we already have?"
• You don't wait to be told exactly what to do - you come with ideas, discuss the biggest ones, then get on and execute.
• You enjoy being hands-on inside tools like Klaviyo, you understand how lifecycle marketing actually works in the real world, and you're motivated by growth, ownership, and impact.
• You like responsibility, fast feedback loops, and working closely with designers, copywriters, and leadership to get things live.
• Most importantly, you're a doer. You bias toward action, progress, and constant improvement. If you prefer endless planning over shipping, this won't be the right fit.

Who are we?

We're a UK-based, world-serving brand in the drink supplement space (think Red Bull but we're not an energy drink). We help people achieve more, win more, and do more with delicious-tasting drinks packed full of clinically-backed ingredients. And beyond performance, every sale we make helps feed and nourish a child for a year through our charitable partner - something we take seriously and are incredibly proud of.

As the business continues to grow, existing customers and subscriptions are a huge part of our future. That's why we're looking for a Retention Marketing Manager to take real ownership of this area and help us unlock the next stage of growth.

What's the role?

This is a growth-focused retention role with real ownership and accountability. You'll be responsible for growing existing customer revenue, with a particular focus on subscription growth, by owning how we communicate with customers across Email, SMS, and Physical Mail.

You won't just execute campaigns - you'll help shape the retention promotional calendar, taking into account stock levels, what the business wants to push, and wider commercial goals. You'll propose ideas, sense-check the most important ones with leadership, then own execution end-to-end.

Your responsibilities will include:

• Retention & Revenue Growth
  • Owning and growing revenue from existing customers
  • Being accountable for subscription growth, uptake, and retention
  • Planning and owning the retention promotional calendar, aligned to stock levels and business priorities
• Email, SMS & Lifecycle Marketing
  • Building, improving, and optimising email flows in Klaviyo
  • Managing and deploying email campaigns and promotions
  • Owning SMS campaigns and lifecycle flows
  • Managing physical mail campaigns, from segmentation and briefing through to deployment and review
  • Ensuring all retention channels work together, not in silos
• Performance & Optimisation
  • Monitoring performance across email, SMS, and physical mail
  • Running tests, spotting opportunities, and iterating quickly
  • Reporting weekly on progress, performance, and priorities
  • Bringing ideas and potential solutions when things aren't working
• Collaboration & Standards
  • Working closely with designers and copywriters to ensure assets are on-brand and effective
  • Acting as a guardian of tone, trust, and customer experience across retention channels
  • Maintaining high standards around accuracy, compliance, and clarity

Your skills & experience

We're not looking for someone who needs months of training. We're looking for someone who can hit the ground running. You'll likely have:

• Proven, hands-on experience in retention, lifecycle, or CRM marketing
• Strong practical experience with email and SMS marketing
• Confidence building and improving flows yourself (even if copy or design comes from others)
• A commercial mindset and comfort being accountable for results
• Experience working in fast-moving, execution-focused environments

Bonus points if you:

• Enjoy working closely with founders or senior leadership
• Like being close to the numbers and seeing direct impact
• Have worked in e-commerce or subscription-based businesses

Location & perks

• Salary: £34,000 - £40,000 (depending on experience)
• Performance-based upside: Clear goals with bonuses and/or pay increases for strong results
• Place of work: Office-based, 4 days per week
• WFH Wednesdays: Available once you're fully trained and up to speed (a genuine perk, not a default)
• Flexible start times: Option to start 1-2 hours earlier or later
• Work closely with leadership: Regular access, fast decisions, real responsibility
• Growth & progression: Strong performance unlocks more responsibility, influence, and reward over time
• Impact & variety: No two weeks look the same - and your work directly drives growth
• Access to our products: Boost your own performance while helping thousands of others do the same

Are we talking to YOU?

If you get excited by growing repeat revenue, optimising lifecycle flows, planning promotions, and seeing the numbers move because of what you built - we want to hear from you. We're looking for someone who's already hands-on, ready to take ownership, and motivated by performance, momentum, and impact. This is a role for people who like responsibility, thrive in an in-office environment, and want their work to genuinely matter.
