The Hello Earth Retention System

One database. Two channels. Compounding LTV.

A retention operating model designed to compound, not just convert. Segmentation that gets sharper every cycle. Flows that learn from behaviour. SMS that earns its place in the inbox. Subscriptions that protect the cohort.

PILLAR 01

RFM segmentation

Recency, Frequency, Monetary value, the segmentation framework that unlocks personalisation at scale. We deploy 9-tier RFM grids in Klaviyo, refreshed weekly, with distinct creative and offer logic for each tier. No one-list-fits-all welcome series.

PILLAR 02

Behavioural triggers

Browse abandonment, cart recovery, post-purchase replenishment, win-back, VIP appreciation. Triggered by behaviour, not calendar. Each flow tuned to the buyer's exact stage and tested against measurable revenue lift, not open rate.

PILLAR 03

Deliverability discipline

Sender reputation. Engagement hygiene. List warm-up. DMARC, SPF, DKIM. Yahoo and Gmail's 2024 sender requirements still trip up most brands. We treat deliverability as a system, not a one-off audit. The inbox is the only channel that matters.

PILLAR 04

LTV measurement

Email and SMS aren't measured by send-level open rates. They're measured by cohort LTV, repeat purchase rate, subscription LTV, and contribution margin per recipient. Triple Whale and Klaviyo CDP feed one definition of winning.

The Channel Maturity Ladder

Every channel earns the right to scale.

No vanity scaling. No premature spend. The Channel Maturity Ladder is how we sequence work, diagnosing where each channel actually sits, then doing the right thing for that altitude. Applied to retention, it looks like this.

Stage 01

Stabilise

Fix the foundations. Audit the list, recover deliverability, deploy the core flows, restore measurement integrity.

Stage 02

Optimise

Once the foundation is sound, drive efficiency. RFM grids deployed, segments sharpened, predictive analytics active.

Stage 03

Scale

Now retention compounds. Subscription layer active. Loyalty programme integrated. LTV becomes the primary acquisition lever.

Subscriptions & loyalty

Where retention compounds into LTV.

For replenishment, FMCG and consumables brands, subscriptions are the single biggest LTV multiplier in DTC. A subscriber's LTV is typically 3–5× a one-off purchaser. A churned subscriber recovered through a smart win-back typically recovers 60–80% of original LTV. Loyalty layered on top compounds the effect: VIP tiers, points-led referral, replenishment rewards.

As Recharge Partners, we deploy subscriptions as a retention engine with intelligent churn prevention, replenishment timing tuned to the product cycle, smart skip/swap logic, and post-cancel win-back flows that recover meaningful cohorts. Layered with LoyaltyLion or Smile.io, the result is a retention stack that turns the average buyer into a high-LTV cohort.

“Working with Hello Earth has been brilliant from start to finish.They've been a true partner through some of our biggest moments - our Dragons' Den appearance, the launch of our first TV ad, and a period of huge growth for the business. Whatever we threw at them, they delivered.What stood out most was their communication: always clear and always fast. The content they produced was consistently excellent, and beyond the deliverables, they genuinely helped us shape and sharpen our brand. I couldn't recommend them more highly.”
Lauren Hale - Head of Growth Sprive
“"Working with Hello Earth has been a great experience. The team is consistently communicative, collaborative, and easy to work with. They bring original creative ideas to every brief and have a strong understanding of what performs well in the UGC space. A dependable and creative partner we’re always happy to work with."”
Amit Ramati - Creative Strategist Free Soul
“Working with the team has been a great experience. Right from the start the whole team has shown a genuine appreciation and understanding of the brand, and as a result the work they do is extremely well-aligned with our brand ethos and tone of voice. They have approached our account with a proactive and initiative-driven mindset, genuinely caring about our business performance. They have not only focused on the specific channels they were responsible for but also considered the broader scope of our business growth. The whole team is in constant communication and always there when we need them, which is a real luxury. We truly appreciate the support we receive from Hello Earth. They have full ownership of their campaigns and projects, and are always refreshingly transparent and honest when identifying areas where we could improve. They are a passionate, committed and results-driven partner, and I would recommend their digital marketing services.”
Lara Smrtnik, Marketing Director The Simple Folk
“The team feel like an extension of our own team. They are not only responsive and proactive but also always bring insights and new ideas to the table. They make us feel like a priority, and that our company means a lot to them. They care about the brand, and it means they're always striving to make the best and most informed decisions for us. Commercially, we’ve seen significant improvement in our metrics across the board, from a decrease in CPA and an increase in ROAS to improving our website conversion rate. They’ve also helped with how the brand shows up online with content, from email to paid creative; they know how to tell the NICE story. If you’re looking for an agency that feels much more collaborative than transactional, then Hello Earth are for you. They have the best intentions for your brand, and are responsive to all targets set.”
Madeline Tomalin-Reeves , Brand Manager NICE
“We were pleasantly surprised by the immediate results they achieved for us. Within the first month of collaboration, our Return on Ad Spend (ROAS) increased significantly, allowing us to confidently invest more in our advertising efforts. However, what truly sets Hello Earth apart is their unwavering commitment to understanding and representing our brand. They went above and beyond to conduct extensive research, ensuring that our advertising materials remained perfectly aligned with our core values and brand identity. This attention to detail not only captured the essence of BRANWYN but also resonated with our target audience in a meaningful way.”
Novak Anton, CTO Branwyn
“From the moment we brought Hello Earth on board, the team and I have been thoroughly impressed. It’s been a revelation working with such a talented, agile group who truly understand how to elevate a brand. We've already seen a significant step change in our output, and the most exciting part is, this is only the beginning. Together, we've made incredible strides towards cementing Biotiful as the leading brand in Natural Gut Health, and the momentum we've created is undeniable.”
Vince Lawson, CMO Biotiful Gut Health
“We joined Hello Earth in 2023 and it has been a foundational reset of how we approach our online marketing. With a focus on continuous content creation and iterative testing we’ve seen improvements across all channels and are delighted with the results so far. We’ve made great strides across meta ads, performance ugc & seo to drive our doorstep delivery sales, office milk and nursery milk leads, and even recruitment of drivers. We’re ‘dairy’ excited to see what we can do together for all of 2024.”
Peter Donoghue, CEO McQueens Dairies
“Working with Hello Earth has been transformational for our business. We've always aspired to be a "DTC first brand" but never been able to unlock true scale on digital ad platforms. Hello Earth's deep knowledge of Meta and other platforms, together with an understanding of the broader inputs such as ad creative, rather than just media buying, has helped us 5x our Shopify sales in less than 12 months.It's not just platform knowledge that distinguishes them from the other agencies in the market. Every agency says that they want to be your "partner" but very few act like it. With Hello Earth we operate off a shared business plan, and have an ongoing dialogue with their team to keep things on track.I've personally recommended Hello Earth to several brands in my network, and continue to do so.”
Ed Armitage, CEO Freja

FAQs

A normal email marketing agency might send out a monthly newsletter and pat themselves on the back. But at Hello Earth, we’re far from normal. We like to view email marketing as the secret sauce, one that’s been designed specifically for the ecommerce space to keep your customers coming back again and again and again. We’ll handle the lot. From subject lines that send open rates soaring to design that has customers crawling back for more, our ecommerce email marketing doesn’t just look pretty, it performs. If you want to build a full funnel marketing approach with us to support your email campaign, from that viral TikTok ad through to a tailored Google Ad strategy, you’re safe in our hands. 

Imagine having the power to drop an irresistible nudge straight into the inbox of someone already eyeballing your brand…that’s email marketing in a nutshell. Clients often ask do I even need an email marketing agency in this day and age? The truth is that if you do email marketing right, you could blow newer channels’ ROI out of the water. That’s because email marketing campaigns target people who are already into you. Whether they’ve signed up for your newsletter or they’ve bought from you in the past, our job as an email marketing agency for ecommerce brands is to nurture these people. Curious browsers become buyers, buyers become repeat customers and repeat customers become brand fanatics. 

(Psst, if you still don’t believe email marketing works, check out our case studies).

A good email marketing strategy is like a well-oiled marketing money-printing machine, targeted, automated, optimised, and triggered as soon as someone signs up for your newsletter or abandons their cart.

As your email marketing agency, we’ll advise on building out a mailing list if you don’t already have one, whether that be through a lead gen strategy, paid social ads or something organic. While your competitors are shouting into the digital void, you’ll be sending laser-guided emails into the correct inboxes. Then we’ll add a subject line that’s catchier than a Christmas song in December. 

Once your recipient opens, they’ll be hit with copy and design that work better together than Ant & Dec. Add in a sprinkle of personalisation, switch on automation so your emails work their magic while you sleep, and then we’ll test and tweak until your results hit harder than a matcha on a Monday morning.

Absolutely. If email is your unstoppable, automated revenue machine, then SMS is like a hard-hitting sidekick that gets the job done fast. iMessage, WhatsApp, you name it, we’ve got you covered. If you’re looking for an SMS marketing agency that can take you from being left on read to instant replies, reach out to Hello Earth today.

The exact cost of working with an email marketing agency depends on what you require from a campaign. Fortunately, our team at Hello Earth knows email marketing better than their own children and will be happy to advise on exactly what you require. If you’re ready to reach out, book a call today, and we’ll take it from there.

Let's make some magic.
