Keep the customers you already paid to win.
Acquisition gets the budget and the glory. Retention is where the margin actually lives. This is the pillar about turning a first order into a second, a third, and a habit.
The three layers of retention
Every pillar in the Revenue System has three layers. Retention breaks down into who you keep, the loop that brings them back, and the timing of the nudge. Most stores have a problem in exactly one of them.
Start here Segmentation
Knowing which customers are worth keeping, and treating the one-time buyer differently from the loyal regular. You cannot retain a group you have not separated.
Then Purchase loop
The mechanics that earn the second order: the post-purchase window, subscriptions done right, the reason to come back before they forget you exist.
Finally Trigger timing
The right message at the right moment. Win-backs, churn saves and flows that fire when behaviour says the customer is ready, not on a generic schedule.
Find out what a customer is really worth
Before you fix retention, see the size of the prize. The LTV Calculator turns your order data into lifetime value, your LTV to CAC ratio, and the one retention lever that moves your number most.

Worked through in order, these cover all three layers. Each one ends with a tool to run on your own store.
You don’t have a CAC problem, you have an LTV problem
Everyone obsesses over the cost of acquiring a customer. The stores that win quietly fix the other side of the equation.
The 48-hour window: post-purchase emails that earn the second order
The most valuable email you will ever send goes out right after the first purchase. Most stores waste it on a bare receipt.
Subscribe and save, done right (the widget most stores get wrong)
Subscriptions are the cleanest repeat-revenue there is, and the easiest to set up badly. The structure that actually retains.

Set these once and they earn while you sleep. The handful of automated flows that do most of the retention heavy lifting.
How to reduce subscription churn (the UX fixes that actually work)
People do not cancel because of price as often as you think. They cancel because the experience made it easy to.
Win-back campaigns that actually bring people back
A lapsed customer is cheaper to re-earn than a stranger is to win. How to spot them and what to actually say.
Where retention sits
Retention is the third pillar of the Revenue System. Traffic brings the right people in, conversion turns the visit into a sale, retention keeps them coming back. Fix them in that order.
