By the numbers

Email is the quiet revenue lever stores ignore.

Most stores chase open rates. The teams making real money chase revenue per email. Here's how the four core flows actually perform on a healthy list.

A typical setup

Five flows, running in parallel.

Most stores try to do email "campaigns". The compounding money is in flows that run on autopilot, week after week, without you touching them.

Trigger

Subscribes

Email or SMS opt-in via popup, footer, or checkout.

Flow 1

Welcome series

3 emails, brand intro, first incentive, social proof.

Outcome

First purchase

Welcome flow alone earns 30%+ of email revenue for most stores.

Trigger

Adds to cart

Product added but checkout abandoned within 2 hours.

Flow 2

Cart recovery

Email + SMS sequence, 1h, 4h, 24h, 48h cadence.

Outcome

Recovered cart

15–30% of abandoners return when the flow is set up properly.

The Method

Six disciplines. Run sequentially. Then forever.

The order is the system. Skip step one and your "open rate" obsession will quietly cost you list health. Start at the foundation.

/ 01

Audit your list health

Engagement segments, sender reputation, deliverability scoring. Know whether you're sending into the inbox or into the void before you change anything else.

/ 02

Segment by behaviour

Engaged 30, lapsed 60, VIPs, browse-only, reorder-due. The segmentation foundation that makes every later flow more profitable.

/ 03

Build the four core flows

Welcome, abandoned cart, browse abandonment, post-purchase. Set up in this order, with the email-and-SMS sequencing rules that actually work in 2026.

/ 04

Write copy that gets opened

Subject line frameworks, preview text discipline, plain-text vs designed templates. The patterns that move open rates and revenue without sounding like a brand reading a script.

/ 05

Layer in campaigns

Once flows run, weekly editorial. Cadence rules, content mix, the calendar template that compounds revenue without burning the list out.

/ 06

Measure what matters

Open rates lie. Revenue per email, list growth velocity, sender reputation trends. The dashboard you'll actually open weekly, plus what to act on.

The Library

Five guides. Read once, reference forever.

Every guide is a downloadable PDF you can print, annotate, and hand to your designer or copywriter. No video to sit through, no playback speed to fiddle with.

/ G01

The List Health Audit Manual

Step-by-step diagnosis for sender reputation, engagement segments, suppression rules, and the exact warnings to fix before sending another campaign. The foundation everything else rests on.

PDF

/ G02

The Four Core Flows Playbook

Welcome, abandoned cart, browse abandonment, post-purchase. The exact email-and-SMS sequencing, timing rules, and conditional logic that quietly recovers £30K+/mo for the average store.

PDF
Frameworks
/ G03

Subject Line & Copy Workbook

Frameworks that actually move open rates, preview text discipline, plain-text vs designed templates, and the human-voice patterns that turn email from a chore into a conversation.

/ G04

The Campaign Calendar Toolkit

Weekly cadence rules, content mix ratios, sale-week vs editorial-week balance, and the planning template that runs your campaigns six weeks ahead without burning your list out.

The Monthly Email Review

The 60-minute monthly review serious teams run on their own programmes. Includes printable agenda, the metrics that matter, and the dashboard you'll actually open every week.

Who it's for

Three store profiles. One disciplined system.

Whether your list has 500 names or 50,000, the framework adapts. The principles are the same, the priorities shift.

i.

The new store

Your list is small but engaged. You don't need a 200-page strategy doc, you need to set up the four core flows and let them run while you focus elsewhere.

List under 5K First flows Klaviyo setup
ii.

The plateaued list

20K–100K subscribers, email contributes 15–25% of revenue, but you suspect there's another tier of performance hidden in flows you've never sequenced properly.

Mid-list Flow rebuilds Segmentation
iii.

The agency owner

You manage email for clients and want a productised audit and flow-build framework you can ship faster, document better, and defend to clients with evidence.

Audit kits Client SOPs Productised
Receipts

Real stores. Real recovered revenue.

Representative results from store teams who ran the framework patiently, set up the flows, and let them compound.

Subject: I owe you a thank-you note
I'd had Klaviyo connected for two years and never set up an abandoned-cart flow properly. The Four Core Flows guide walked me through it in an evening. The cart-recovery flow alone is now adding £14K a month.
Subject: Finally, my list is paying for itself
The List Health Audit forced me to suppress 12,000 dead subscribers. Sender reputation jumped, deliverability fixed itself, and revenue per send tripled in three weeks. Counter-intuitive but true.

Subject: Worth every penny
The Subject Line Workbook unlearned every clickbait habit I had. Open rates went from 21% to 38% across our send list. Revenue followed. My list now earns more than my paid social.
Subject: Productised my agency offer
I run email for seven clients. Used to scope each from scratch. Now I run the audit framework on every new account and ship the four core flows in week one. Doubled my retainer.

FAQ

Things people actually ask.

Anything missing? Message us in the RetainFlow community. We answer within a working day, often in minutes.

Will this work on Klaviyo, Postscript, Attentive, Mailchimp? +
Yes. The frameworks are platform-agnostic, with platform-specific notes called out where they matter. Klaviyo gets the most worked examples since it powers most serious e-commerce stores, but the principles transfer.
My list is small. Is this still useful? +
Especially for small lists. The four core flows compound the most when you set them up early and let them run as the list grows. Small list, set up properly, beats large list run badly nine times out of ten.
Do I need a copywriter or designer? +
No. The Copy Workbook gives you frameworks anyone can apply, and we lean toward plain-text emails over heavily-designed templates because they tend to perform better. If you want polished templates later, the guides include exact briefs you can hand a designer.
How is this different from Klaviyo's free academy? +
Klaviyo's academy teaches you to use Klaviyo. We teach you which flows actually earn revenue, in what order, with what sequencing, on any platform. Different question, different answer.
What's actually inside the RetainFlow community? +
A private Discord with 1,100+ active members, coaches, alumni. Channels for flow reviews, deliverability questions, copy feedback, and weekly office-hour links.
How does the 30-day guarantee work? +
Read the first three guides, set up at least the four core flows, don't see measurable improvement, email within 30 days. Refund processed inside 24 hours. No questions, no exit form.
