Email & Retention
Turn First-Time Buyers Into Repeat Revenue
Lifecycle email and SMS built on how your customers actually buy — replenishment timing, browse behaviour and purchase history. Owned-channel revenue that compounds instead of resetting every month with your ad budget.
- Flows timed to your product’s real replenishment window, not a generic template
- Segmentation built from purchase and behaviour data you already own
- Reported on email-attributed revenue and repeat purchase rate, not open rate

The Problem
The customer retention challenge
Nine reasons owned revenue stays flat. Most stores have six or seven of them, and every one is cheaper to fix than buying the equivalent revenue through ads.
Too many one-time buyers
A customer base that looks large and behaves like a stream of strangers. Acquisition keeps refilling a bucket nobody has patched.
Low repeat purchase rate
A consumable category running at 18–20% repeat when it should sustain double that. The demand exists; nothing is asking for it.
Abandoned carts
Sessions that reached the cart and left, recovered by a single generic email sent four hours later, if at all.
Weak post-purchase engagement
The order confirmation is the last thing a customer hears until the next promo blast. The highest-intent window in the whole lifecycle, unused.
Generic promotional emails
The same 15% off to the whole list every fortnight. It trains people to wait for discounts and to ignore everything else.
Poor customer segmentation
One list, one message. First-time buyers, VIPs and lapsed customers all treated identically, so none of them get anything relevant.
Underused customer data
Purchase history, browse behaviour and product affinity sitting in the platform unused, while campaigns are planned on gut feel.
Low customer lifetime value
LTV that never grows enough to justify rising acquisition costs, so every CPC increase squeezes the same thin margin.
Overdependence on paid acquisition
Revenue that stops the week the ad spend stops. No owned channel doing meaningful work in the background.
What We Do
Our email & retention services
Ten workstreams. Flows and segmentation come first — campaigns sent into an unsegmented list are the least valuable thing on this page.
Email Marketing Strategy
Channel role, cadence, offer architecture and how email fits next to paid.
Email Automation & Flows
The always-on lifecycle programme that earns revenue without a send button.
Campaign Management
Planned promotional calendar, built, sent and reported on every month.
Customer Segmentation
Segments built from purchase, browse and product-affinity data you already hold.
SMS Marketing
Compliant SMS for the moments that genuinely justify interrupting someone.
Abandoned Cart Recovery
Cart, checkout and browse recovery sequences timed to actual drop-off behaviour.
Post-Purchase Marketing
Shipping, education, review request and the second-purchase prompt.
Win-Back Campaigns
Lapsed-customer automation triggered on your real purchase-cycle data.
Loyalty & Retention Strategy
VIP tiers, subscription mechanics and rewards where the category supports them.
Email Testing & Optimization
Subject lines, offers, timing and creative, tested on revenue per recipient.
Retention compounds fastest alongside conversion optimization and paid advertising, or inside a full eCommerce management engagement.
Lifecycle
Email automations & lifecycle flows
One journey from first subscribe to win-back. Every stage has a trigger, a message and a metric — nothing runs because a template included it.

Win-Back
The eleven flows that carry the revenue
Welcome series
Sets expectation, delivers the incentive and earns the first purchase.
Browse abandonment
Triggered on category and product views that did not reach the cart.
Cart abandonment
Multi-step recovery with escalating incentive only where margin allows.
Checkout abandonment
Separate from cart, because reaching checkout is a much stronger signal.
Post-purchase
Shipping updates, product education and setting up the second order.
Product recommendations
Driven by affinity and category, not by best-sellers for everyone.
Cross-sell / upsell
Timed to when the first product has actually been used.
Review request
Sent on delivery plus usage window, feeding social proof back to the PDP.
Replenishment
Timed per product from your real repurchase interval data.
Customer win-back
Triggered when a customer passes 1.5x their expected repurchase cycle.
VIP / customer loyalty
Recognition and early access for the cohort carrying your margin.
The Process
Our email & retention process
Six stages. The last two run continuously once the programme is live.
01
Audit & Analyze
Your existing flows, list health, deliverability, purchase-interval data and where revenue is currently coming from. We quantify the gap before proposing anything.
02
Segment Customers
Segments built on purchase history, product affinity, order value and recency — not on an arbitrary engagement window.
03
Build the Strategy
Lifecycle map, channel split between email and SMS, offer architecture and the cadence each segment should actually receive.
04
Create & Automate
Copy, creative and build. Flows go live in priority order so revenue starts before the full programme is finished.
05
Test & Optimize
Subject lines, timing, offers and creative, measured on revenue per recipient rather than open rate.
06
Retain & Grow
Monthly reporting on repeat rate, LTV and flow revenue, with the backlog re-prioritised on what moved.

01
Convert
Turn a subscriber or an abandoned session into a first order.
- Welcome incentives
- Cart recovery
- First-purchase campaigns
02
Engage
Stay relevant between purchases without training people to wait for discounts.
- Personalized campaigns
- Relevant content
- Customer segmentation
03
Retain
Earn the second and third order, where the margin actually lives.
- Post-purchase communication
- Replenishment
- Loyalty programs
04
Grow
Increase order value and reactivate the customers worth reactivating.
- Cross-sells
- Upsells
- VIP campaigns
- Win-back strategies
By Goal
Retention marketing by business goal
Seven outcomes and the retention strategy each one needs.
Increase Repeat Purchases
Lifecycle + post-purchase campaigns
Set up the second order in the window right after the first, when intent is highest and cost is zero.
Recover Lost Sales
Cart & checkout abandonment
Separate sequences for cart and checkout, timed to real drop-off behaviour rather than a fixed delay.
Increase LTV
Segmentation + personalization
Stop sending one message to everyone; relevance is what extends the customer relationship.
Increase AOV
Cross-sell & upsell campaigns
Pairing timed to when the first product has been used, measured on incremental revenue.
Re-Engage Customers
Win-back automation
Triggered on your actual purchase-cycle data, not a generic 90-day lapse rule.
Build Customer Loyalty
Loyalty + VIP campaigns
Recognition, early access and tiering for the cohort that already carries your margin.
Reduce Paid Ad Dependency
Owned-channel revenue growth
Shift a share of revenue to a channel with no media cost, so a CPC increase stops being existential.

Why Us
Why choose our email & retention services
Eight things that separate lifecycle retention from sending more newsletters.
eCommerce-Focused Strategy
Replenishment windows, subscription mechanics and category purchase cycles are our daily work. B2B nurture playbooks do not transfer to a consumables brand.
Lifecycle-Based Marketing
The programme is built as a journey, not a calendar of sends. Automation carries the revenue; campaigns add to it.
Data-Driven Segmentation
Segments come from purchase interval, product affinity and order value — data you already own and almost certainly are not using.
Personalized Customer Journeys
A first-time buyer, a lapsed customer and a VIP get genuinely different sequences, not the same email with a different name token.
Revenue-Focused Automation
Flows are measured on revenue per recipient. Open rate is a diagnostic; it has never paid an invoice.
Continuous Testing
Subject lines, offers, timing and creative tested on a running schedule, with results documented either way.
Cross-Channel Retention
Email, SMS and on-site coordinated so the same customer is not hit three times with the same offer in one afternoon.
Transparent Reporting
Email-attributed revenue reconciled against store revenue, plus repeat rate and LTV by cohort. Including the flows that underperformed.
Proof

CHALLENGE
A 21% repeat purchase rate in a consumables category that should sustain far more, with one generic monthly newsletter and no automation beyond an order confirmation.
RETENTION STRATEGY
Rebuilt the programme around per-product replenishment timing rather than a single generic flow, segmented by product affinity and order interval, and added win-back triggered on 1.5x expected cycle.
IMPLEMENTATION
Eleven flows built over nine weeks, replenishment timing derived per SKU from two years of order data, and SMS added only for the replenishment and win-back moments.

CHALLENGE
Strong repeat intent with no subscription mechanic: 91% of second orders were placed manually between day 26 and day 38, and the subscribe option converted under 2%.
RETENTION STRATEGY
Built a post-purchase flow offering subscription conversion at day 21, rebuilt the welcome series around the subscribe-and-save proposition, and added lapse-risk segmentation for subscribers.
IMPLEMENTATION
Post-purchase sequence timed to the observed 26–38 day window, PDP and email messaging aligned on per-unit saving, and a separate subscription-lapse win-back path.

CHALLENGE
A subscription box launch with no owned-channel programme, relying entirely on paid social for both acquisition and the retention that a box model depends on.
RETENTION STRATEGY
Built the full lifecycle from launch: welcome, cart and checkout recovery, onboarding for the first three boxes, pause-and-skip handling, and a referral-led loyalty layer.
IMPLEMENTATION
Cart and checkout treated as separate sequences, first-three-box onboarding to survive the highest-churn window, and a pause flow to catch cancellations before they happened.

Retention outcomes vary heavily by category. A consumable with a 30-day cycle has far more headroom than a once-every-five-years purchase, and we will tell you which one you are on the call.
FAQs
Email & retention FAQs
Eight questions that come up before most retention engagements. More on our full FAQ page.
How much revenue should email actually drive?
For most eCommerce brands with a functioning lifecycle programme, 20–35% of total revenue is a realistic range, with consumables and subscription models at the top of it. If you are under 10%, the gap is almost always missing automation rather than insufficient campaign volume. Anyone quoting you a single benchmark without asking your category and repurchase cycle is guessing.
What is the difference between flows and campaigns?
Flows are automated and triggered by behaviour — someone subscribes, abandons a cart, or passes their replenishment window. Campaigns are one-off sends to a segment. Flows typically produce the majority of email revenue at a fraction of the effort, which is why we build them first and treat campaigns as the addition rather than the programme.
How long before retention work shows results?
Cart and checkout recovery usually shows within two weeks of going live. Welcome and post-purchase flows show inside a month. Replenishment and win-back take one full purchase cycle to prove out — so 30 days for a consumable, considerably longer for a durable good. Repeat purchase rate and LTV are cohort metrics and need two to three cycles to read honestly.
Do we need SMS as well as email?
Not always. SMS earns its place for genuinely time-sensitive moments — replenishment, back-in-stock, order issues, and sometimes cart recovery. Used as a second promotional channel it burns the list quickly and gets expensive. We would rather run email properly and add SMS to three or four specific triggers than launch both at half strength.
What does email & retention cost?
Standalone retention engagements typically run $2,500–$7,000/month depending on list size, platform, campaign cadence and how much creative production is in scope, separate from your ESP subscription. Inside a full management engagement it is part of the wider fee. Our pricing page explains how we scope it.
Will you migrate us to Klaviyo?
Only if the current platform is genuinely limiting you. Klaviyo is our default recommendation for Shopify because of its flow logic and product-level segmentation, but a migration costs time and risks list health. If Mailchimp or Omnisend can do what your programme needs, we will build it there and say so.
Who writes the emails and makes the creative?
We do, unless you would rather your team did. Copy, layout and campaign graphics are in scope by default. If you have brand guidelines or an in-house designer we work to them; if you do not, we build a template system that stays consistent without needing a designer for every send.
How do you handle deliverability and list health?
It is part of the audit before anything is built. Authentication records, sending reputation, engagement-based sunsetting and re-permission where a list has gone stale. Building sophisticated flows on a domain with damaged reputation is wasted work, so we fix that first even when it is the least interesting part of the engagement.
