Email & SMS CopywriterAbout Momentum

Momentum Marketing is the dedicated email and SMS retention agency within CGC Ventures , an operator-led ecommerce and technology group.

We build and manage the full retention engine for DTC ecommerce brands, from strategy and campaign planning to lifecycle flows, copy and execution inside Klaviyo. We back our work with a revenue attribution guarantee and hold ourselves accountable to the numbers.

We are direct, commercially minded and allergic to agency fluff. Our clients trust us to grow customer lifetime value and protect their margins as acquisition costs rise. Every campaign and every email has to earn its place in the inbox.

We are growing and looking for a senior copywriter who can take complete ownership of the copy and retention strategy for a pod of brands.

The Role

You will be the lead copywriter within a client pod. Each pod manages approximately five to seven brands, depending on capacity and team structure, and you will own the copy across every campaign and lifecycle flow for the brands assigned to you.

This is not a role where you write a few isolated emails each week. You will be the retention copy engine for your pod, and your work will directly influence client revenue, repeat-purchase rate and customer lifetime value.

The role combines high-level copywriting with hands-on retention strategy. You must be able to decide what should be sent, when it should be sent, who should receive it and how each message supports the customer's journey.

What You Will Do

- Build a complete monthly campaign calendar for every brand in your pod. This is a core, non-negotiable deliverable.
- Write all campaign copy in line with the approved calendar, including subject lines, preview text, body copy and calls to action.
- Write and optimise lifecycle flows, including Welcome, Abandoned Checkout, Abandoned Cart, Browse Abandonment, Site Abandonment, Post-Purchase, Winback and Sunset flows.
- Take particular ownership of post-purchase strategy. We expect you to know how to turn a first-time customer into a second- and third-time buyer through education, product usage, cross-selling, replenishment and subscription messaging.
- Design flow structures strategically inside Klaviyo, including conditional splits based on customer behaviour, buyer intent, order history and customer value. You should understand where each message sits, who receives it and why.
- Adapt every piece of copy to the brand's voice, product, customer awareness level, target region and cultural context.
- Review campaign and flow performance, identify what is and is not working, and use the data to improve future copy and strategy.
- Complete all assigned work by its deadline and communicate early if a genuine blocker arises. The working day begins at 10:00 AM in the agreed team timezone, but performance is measured primarily by the quality,



consistency and timeliness of your output—not by hours logged.
- Work closely with strategists, designers, account managers and the rest of your pod to keep client work moving at a high standard.

Non-Negotiable: Supplement Brand Experience You must have proven, demonstrable success writing retention copy for seven- or eight-figure supplement brands . This is a hard prerequisite, not a preference.

You should understand supplement customer psychology at a working level, including:

- Why supplement customers buy, why they lapse and what genuinely reactivates them.
- How to drive replenishment, repeat purchases and subscriptions without sounding repetitive or desperate.
- How to communicate ingredients, mechanisms, benefits and product differentiation clearly and persuasively.
- How to write responsibly within the boundaries of health claims and brand compliance requirements.
- How to build post-purchase sequences that improve product usage, set expectations and turn a first order into a second and third.

You will be asked to provide relevant portfolio samples and proof of performance from seven- or eight-figure supplement brands. This should include real results such as click rates, conversion performance and attributed revenue. Anonymised evidence is acceptable where required by an NDA, provided the results can be credibly verified. If you cannot demonstrate this experience, please do not apply.

Manual, Original Copy Only

All final copy must be written by you. AI-generated copy, lightly edited AI output and prompt-paste-submit workflows will not be accepted.

Strong retention copy requires original thought, commercial judgement and a genuine understanding of the customer. It must adapt to a brand's voice, regional culture and natural language patterns. Generic copy that could belong to any product or market does not meet our standard.

If AI is doing the thinking or writing for you, this role is not the right fit.

Skills and Knowledge Required

- Conversion copywriting: High-performing email copy is your craft, and you can support that claim with real work and measurable results.
- Retention strategy: You can build a monthly calendar that balances promotional, educational, brand-building and lifecycle content, and you can explain the commercial reasoning behind every send.
- Klaviyo: You have solid working knowledge of flow structure, conditional splits, segmentation, buyer intent, customer value and how automation logic connects to copy.
- Post-purchase mastery:



You can speak in depth about how you build post-purchase journeys that improve customer experience and drive second and third orders.
- Supplement expertise: You understand the category, its customers, its compliance sensitivities and the difference between persuasive benefit-led copy and unsupported claims.
- Commercial awareness: You understand that opens are not the end goal. You think in terms of clicks, conversions, revenue, repeat purchases, customer lifetime value and margin.
- Cultural and linguistic range: You can adapt tone, language, references and selling angles for different regions and audiences.
- Ownership and organisation: You can manage multiple brands and deadlines without needing to be chased.
- Collaboration: You communicate clearly, support your pod and contribute positively to the wider team.

The Hiring Process
1. Application, portfolio and proof of performance from relevant supplement brands.
2. Shortlisted candidates complete a practical copy and strategy test.
3. Interview with the Momentum team.
4. Final culture and working-style assessment.

Culture and Expectations Please read this section carefully. We take it as seriously as technical ability.
- Punctuality and reliability: The working day begins at 10:00 AM. Deadlines are commitments, and consistent communication is expected.
- High standards, low ego: Talent does not excuse disrespect, entitlement or behaviour that damages team morale. We expect professionalism and accountability from everyone.
- Team first: We help one another across the pod and the wider agency. This is not an environment for lone wolves.
- A learner's mindset: There is always something to improve. You should welcome thoughtful feedback, act on it and be willing to challenge your own assumptions.
- Hunger: We want ambitious people who care about becoming excellent at their craft and helping their clients win—not people looking to coast.
- Ownership: If something is unclear or at risk, raise it early. We value people who solve problems rather than wait to be managed through them.

Compensation and Growth
- Competitive base compensation based on experience.
- Quarterly performance bonus with the potential to exceed one full month's base compensation. When your pod's brands win, you share in the upside.
- Long-term contract with meaningful opportunities for responsibility and progression as Momentum and CGC Ventures scale.
