RETENTION MARKETING

Post-iOS14 made customer acquisition 40% more expensive — US brands growing profitably are doing it through retention, not acquisition

The post-iOS14 environment fundamentally changed the unit economics of US e-commerce. CPMs are higher. Attribution is noisier. Customer acquisition cost has risen 40 to 60% across Meta and Google for most Shopify brands. The brands that are growing profitably in this environment have shifted investment toward retention: subscription programmes, loyalty systems, and LTV-focused lifecycle marketing that gets more revenue from customers already acquired. We build and operate those retention systems.

This is for you if

Who This Is For

You sell supplements, beauty products, pet supplies, food, or another consumable category. Customers buy once, use the product, and then either reorder or go to Amazon. You have no Subscribe and Save option on your Shopify store. You are leaving 3 to 4x LTV on the table for every customer who could be a subscriber but is currently a one-time buyer.

You have a Yotpo or LoyaltyLion loyalty programme. You have Klaviyo email flows. But the two are not talking to each other. Points earned in the loyalty programme are not triggering Klaviyo flows. Tier upgrades are not generating celebration emails. Points expiry is not sending automated warnings. The loyalty programme and the email marketing system are running in parallel without connecting, and the retention impact of both is reduced as a result.

Your acquisition investment keeps growing because you need to replace churned customers. Your returning customer revenue percentage sits below 25% and it is not improving despite a growing total customer count. You have the awareness that retention is a gap. You need someone to build the retention system that moves that number.

What's broken

What's Broken

No subscription offering for a product that customers need to replenish

Supplements, skincare, coffee, pet food, and other consumables without a Subscribe and Save option are generating one-time purchase LTV when they could be generating subscription LTV. A customer who buys a 30-day supplement supply once and does not subscribe has an LTV of one order value. A customer who subscribes to monthly replenishment has an LTV of 12 order values in the first year alone. The gap between one-time and subscription LTV is the single largest addressable retention opportunity for US brands in consumable categories.

Loyalty programme not integrated with email flows in Klaviyo

The loyalty programme is tracking points. Klaviyo is sending emails. But a customer who earns 500 points does not receive a Klaviyo email telling them they are 200 points away from a reward. A customer who reaches VIP tier does not receive a tier-upgrade celebration email. A customer whose points are about to expire does not receive a warning. The loyalty programme and the email system are siloed, and the result is a loyalty programme that generates loyalty account activity but minimal incremental purchase behaviour.

Returning customer revenue below 35% of total revenue

The benchmark for a healthy US e-commerce retention programme is 35 to 45% of total revenue coming from returning customers. Brands below 35% are over-reliant on acquisition to hit their revenue targets. When CAC rises (as it has consistently since iOS14), brands below the retention benchmark face a direct profitability problem because they cannot grow their customer base cheaply enough to compensate for the low LTV of one-time buyers. Increasing returning customer revenue to 35% or above creates a revenue base that is not dependent on the volatility of paid acquisition.

Win-back campaigns sent to the entire lapsed segment at a flat discount

A 10% win-back discount sent to every lapsed customer treats a customer who spent USD 2,000 over three orders identically to a customer who spent USD 45 on a single order. The high-LTV customer would likely return at no discount (or at a smaller one). The low-LTV customer may never return regardless of the discount offered. Sending a uniform discount to the entire lapsed segment wastes margin on both groups and reduces the profitability of the win-back campaign. Segmenting by historical LTV and calibrating the win-back offer to the customer's value is the standard approach for US brands with a mature retention programme.

What we engineer

What We Do

Subscription Programme Strategy and Implementation

For brands selling replenishable products, we design and implement a subscription programme using Recharge or Skio, the two dominant subscription platforms for US Shopify brands. This includes: subscription offer design (discount depth, frequency options, cancel and pause mechanics), product page subscription upsell copy, post-purchase subscription conversion flow (a sequence that offers one-time buyers a subscription upgrade after their first order), and a subscriber retention flow (a churn prevention sequence for subscribers who cancel or indicate intent to cancel).

Loyalty Programme and Klaviyo Integration

We connect the loyalty platform (Yotpo Loyalty or LoyaltyLion) to Klaviyo and build the full suite of loyalty-triggered email flows: points earn confirmation, milestone approach notification (200 points away from next reward), tier upgrade celebration, expiry warning (30 days before points expire), and redemption reminder for customers who have earned enough to redeem but have not done so. These flows run automatically based on loyalty events, not on a scheduled send calendar.

Post-Purchase Lifecycle Sequencing

We build a complete post-purchase sequence from order confirmation to day 120. The sequence is segmented by product category (consumable vs. non-consumable) and by purchase order (first purchase vs. second purchase). First-time buyers enter a different sequence than returning buyers. Consumable product buyers receive a subscription upgrade offer at day 15. Non-consumable product buyers receive cross-sell and discovery offers based on category affinity.

LTV-Segmented Win-Back Campaign Design

We build a win-back framework that segments lapsed customers by historical LTV into three tiers: high-LTV (top 20% by lifetime spend), mid-LTV (middle 40%), and low-LTV (bottom 40%). Each tier receives a different win-back offer: high-LTV customers receive a personal outreach with a meaningful reward; mid-LTV customers receive a standard win-back offer; low-LTV customers receive a lightweight re-engagement with no discount. This structure maximises recovery rate while protecting margin.

Subscription Upgrade Flow for One-Time Buyers

We build a Klaviyo flow that identifies one-time buyers of replenishable products and delivers a subscription upgrade offer between day 15 and day 30 after their first purchase, when they have experienced the product but have not yet committed to reordering. The offer is framed around convenience and savings rather than discount alone. Conversion rates on subscription upgrade flows are typically 8 to 15% of eligible first-time buyers.

VIP Programme Design

We identify the top 10 to 15% of customers by lifetime spend and design a VIP tier with meaningful benefits: an elevated loyalty earn rate, early access to new products and limited drops, a dedicated customer service pathway, and an annual VIP appreciation communication. VIP customers have a materially higher retention rate when the tier is actively communicated and maintained.

Returning Customer Revenue Tracking and Optimisation

We set up Shopify and Klaviyo reporting to track returning customer revenue as a percentage of total revenue on a monthly basis. The target is 35 to 45%. We build a roadmap of retention investments with a projected contribution to the returning customer revenue percentage, so the founder can see the expected revenue impact of each retention programme component.

Subscription Churn Prevention Flow

For brands with an existing subscription programme, we build a churn prevention flow that triggers when a subscriber cancels, pauses, or hits a failed payment. The flow offers a pause option before cancel, a personalised retention offer for subscribers who have been active for 3 or more months, and a win-back sequence for subscribers who cancelled more than 60 days ago.

After
Before Supplements, skincare, coffee, pet food, and other consumables without a Subscribe and Save option are generating one-time purchase LTV when they could be generating subscription LTV. A customer who buys a 30-day supplement supply once and does not subscribe has an LTV of one order value. A customer who subscribes to monthly replenishment has an LTV of 12 order values in the first year alone. The gap between one-time and subscription LTV is the single largest addressable retention opportunity for US brands in consumable categories.
After The subscription programme converts a percentage of one-time buyers into subscribers. Each conversion replaces a single-order LTV with a multi-order annual LTV. For a brand with an average order value of USD 60 and a subscription conversion rate of 10% on first-time buyers, this represents a material shift in the blended LTV of the acquired customer cohort and a direct improvement in the profitability of paid acquisition.
Before The loyalty programme is tracking points. Klaviyo is sending emails. But a customer who earns 500 points does not receive a Klaviyo email telling them they are 200 points away from a reward. A customer who reaches VIP tier does not receive a tier-upgrade celebration email. A customer whose points are about to expire does not receive a warning. The loyalty programme and the email system are siloed, and the result is a loyalty programme that generates loyalty account activity but minimal incremental purchase behaviour.
After Loyalty-triggered Klaviyo flows push customers to redeem points, celebrate tier upgrades, and prevent expiry. The loyalty programme moves from a passive points-tracking system to an active retention communication layer. Brands that add loyalty-triggered flows typically see a 15 to 25% increase in loyalty programme contribution to revenue within 60 days.
Before The benchmark for a healthy US e-commerce retention programme is 35 to 45% of total revenue coming from returning customers. Brands below 35% are over-reliant on acquisition to hit their revenue targets. When CAC rises (as it has consistently since iOS14), brands below the retention benchmark face a direct profitability problem because they cannot grow their customer base cheaply enough to compensate for the low LTV of one-time buyers. Increasing returning customer revenue to 35% or above creates a revenue base that is not dependent on the volatility of paid acquisition.
After As the subscription programme, loyalty flows, and post-purchase sequences compound over time, the returning customer revenue percentage climbs. This reduces the revenue dependence on paid acquisition and improves profitability. Each percentage point increase in returning customer revenue represents a reduction in the effective blended CAC required to hit a given revenue target.
Before A 10% win-back discount sent to every lapsed customer treats a customer who spent USD 2,000 over three orders identically to a customer who spent USD 45 on a single order. The high-LTV customer would likely return at no discount (or at a smaller one). The low-LTV customer may never return regardless of the discount offered. Sending a uniform discount to the entire lapsed segment wastes margin on both groups and reduces the profitability of the win-back campaign. Segmenting by historical LTV and calibrating the win-back offer to the customer's value is the standard approach for US brands with a mature retention programme.
After LTV-segmented win-back campaigns direct the highest-quality offers to the customers most worth recovering. High-LTV customers who would return at no discount are not given a 20% discount. Low-LTV customers who are unlikely to return regardless of offer are not given expensive win-back incentives. The result is a higher net margin on win-back revenue and a higher recovery rate on the high-LTV segment that is worth investing in.
How it works

Process

  1. 01

    Retention and LTV Audit

    Week 1

    We pull cohort data from Shopify and Klaviyo and map: returning customer revenue as a percentage of total revenue, repeat-purchase rate by cohort, subscription programme performance (if one exists), loyalty programme engagement rate, and blended LTV by acquisition channel. We identify the highest-impact retention gaps and produce a prioritised retention roadmap with projected revenue impact for each component.

  2. 02

    Subscription and Loyalty Strategy Design

    Weeks 2 to 3

    We design the subscription programme structure (for brands without one) or audit and improve the existing programme. We map the Klaviyo-loyalty integration points and design the flow architecture. We design the win-back segmentation framework and calibrate offer levels by LTV tier. All strategy documents are reviewed with the founder before build begins.

  3. 03

    Build and Platform Configuration

    Weeks 3 to 6

    We implement Recharge or Skio for the subscription programme. We build Klaviyo loyalty-trigger flows. We configure LTV-segmented win-back campaigns. We build the subscription upgrade flow for one-time buyers. We set up the subscription churn prevention flow. All flows are tested end-to-end before activation.

  4. 04

    Launch, Monitor, and Optimise

    Ongoing

    Flows go live. We monitor subscription conversion rates, loyalty flow engagement, win-back recovery rates by LTV tier, and returning customer revenue percentage monthly. A monthly retention report is delivered with performance data and a clear recommendation for the next priority test.

Common questions

FAQ

What subscription platform should I use for a Shopify store selling replenishable products in the US?

Recharge and Skio are the two dominant subscription platforms for US Shopify brands. Recharge has the larger installed base and the most mature third-party integrations, including deep Klaviyo integration for subscription lifecycle flows. Skio is newer, has a more modern checkout experience, and is growing rapidly among Shopify Plus brands because of its co-developed checkout with Shopify. For brands on Shopify (not Plus) with a straightforward replenishment model, Recharge is the more tested option. For Shopify Plus brands that want a more native checkout experience and are comfortable with a newer platform, Skio is a strong choice. The platform decision is secondary to the subscription offer design: frequency options, pause mechanics, and the discount structure matter more than which platform hosts the programme.

How do I integrate a loyalty programme with Klaviyo email flows?

LoyaltyLion and Yotpo Loyalty both have native Klaviyo integrations that push loyalty events as Klaviyo custom properties and events. Once the integration is active, each loyalty event (point earn, tier upgrade, points expiry approaching) becomes a trigger for a Klaviyo automated flow. The specific flows to build first are: a points milestone approach flow (triggered when a customer is within 200 points of the next reward threshold), a tier upgrade celebration flow, and a points expiry warning flow (triggered 30 days before expiry). These three flows address the most common loyalty engagement gaps. Brands that add these flows after running a passive loyalty programme typically see a measurable increase in redemption rate and in the proportion of loyalty members who make a purchase within 60 days of a loyalty communication.

What percentage of revenue should come from returning customers for a US e-commerce brand?

The benchmark for a healthy US e-commerce retention programme is 35 to 45% of total revenue coming from returning customers. Brands below 35% are over-dependent on acquisition and face deteriorating profitability as CAC rises. Brands above 45% are typically operating mature subscription or loyalty programmes and have a customer base with strong habitual repurchase behaviour. For brands currently at 20 to 25% returning customer revenue, the path to 35% typically runs through three investments: a subscription programme for consumable products, an active loyalty communication plan, and an automated win-back flow for lapsed customers. Each component contributes incrementally to the returning customer revenue percentage.

How do I identify which lapsed customers are worth a win-back discount versus a no-discount re-engagement?

The segmentation variable is historical lifetime spend. Customers in the top 20% of lifetime spend (high-LTV) are worth a meaningful win-back offer because the expected future value of retaining them exceeds the cost of the incentive. Customers in the bottom 40% of lifetime spend (low-LTV) have a low expected future value and are unlikely to become high-LTV customers regardless of the win-back offer; a lightweight no-discount re-engagement message tests whether they return organically. Customers in the middle 40% receive a standard win-back offer calibrated to a positive expected margin after discount. In Klaviyo, this segmentation is built using the predicted customer lifetime value property (available on Klaviyo's ML models) or a custom property calculated from Shopify order history. The LTV-segmented approach consistently outperforms flat-discount win-back campaigns on both recovery rate and win-back margin.

What is the difference between a loyalty programme and a VIP programme for US e-commerce?

A loyalty programme is a points-based system open to all customers that rewards purchase, review, and referral behaviour with redeemable credits. A VIP programme is a tier-based system that recognises the brand's highest-value customers with exclusive benefits not available to the general customer base. Most mature US e-commerce brands run both: a loyalty programme for the full customer base and a VIP tier within or alongside the loyalty programme for the top 10 to 15% of customers by spend. The VIP programme adds benefits that points alone cannot provide: early access to product launches, a higher earn rate on purchases, dedicated customer service, and communications that make the VIP customer feel genuinely recognised rather than part of a mass programme. Retention rates for customers in an actively managed VIP tier are typically 20 to 30 percentage points higher than for customers in the standard loyalty tier.

Acquisition got more expensive. Retention economics are how profitable US brands are adapting.

Post-iOS14, the US brands with sustainable growth are not the ones who found a cheaper way to acquire customers. They are the ones who made each acquired customer worth more: subscription programmes that convert one-time buyers into recurring revenue, loyalty flows that keep customers returning between purchases, win-back campaigns that recover high-LTV customers without wasting margin on the rest, and a returning customer revenue percentage that sits at 35 to 45% rather than 20%. The retention system is what changes the economics. We build it.
