Retention marketing: the cheapest revenue most ecommerce brands ignore.
Every customer in your database cost you money.
You paid Meta to find them. You paid for the creative that stopped them. You probably gave them 10% off to get the first order over the line. By the time that first purchase lands, a decent share of the revenue has already gone back out the door.
The profit was never in the first order. The profit is in the second, third and fourth.
And most brands I audit have built an entire business around getting the first one, then let the customer walk out into the street and never speak to them again.
The maths founders don’t run
Take a customer you acquired for $45. Your average order is $90, your gross margin is 55%. So that first order nets you about $50 before you’ve paid for anything else, on a customer who cost $45 to get. You are, technically, up five dollars.
That’s not a business. That’s a very stressful hobby.
Now let the same customer buy twice more over the next nine months. Those orders cost you nothing to acquire. No ads, no creative, no discount to a stranger who doesn’t trust you yet. Just an email that landed at the right moment. Same customer. Same product. Wildly different business.
This is why two brands with identical ad performance can have completely different outcomes. It’s the same reason a brand with brilliant paid and no retention always feels expensive to scale. Because it is. You’re paying full price for every single dollar of revenue, forever, and wondering why growth costs so much.
A brand with great paid and no retention is a leaky bucket. A brand with both is a machine.
Why founders under-invest here, every time
I’ve watched this pattern for years and it’s remarkably consistent.
New customers feel like growth. Existing customers feel like admin. There’s a dopamine hit to a new order from a stranger that a repeat order just doesn’t give you. Paid feels like hunting. Retention feels like filing.
It’s slower to show up. Turn on ads, see something within days. Turn on flows, and the compounding happens over months, quietly, in the background, in a channel nobody’s watching.
It’s not where the panic is. Founders work on whatever is loudest, and retention never shouts. It just sits there, unbuilt, costing you money in a way that never appears on any dashboard as a loss.
And nobody sold it to them. The agency they hired sells ads. So they talk about ads, report on ads, and quietly leave the cheapest revenue in the business on the table, because it isn’t in their scope and it isn’t in their interest.
The flows doing the heavy lifting
You don’t need forty flows. Most brands are enormously better off with a handful, built properly, than with a sprawling account nobody’s looked at since setup.
Welcome. Someone just gave you their email. It’s the single warmest moment you’ll ever have with them, and most brands answer it with a discount code and silence. This is where you say who you are and why you exist, and it is consistently one of the highest-revenue flows in any account I open.
Abandoned checkout, and abandoned browse. They wanted it. Something got in the way. Whatever it was, price, shipping, doubt, a crying toddler, the job is to remove the friction and return them to the exact moment they left. Browse abandonment is the one most brands skip, and it’s frequently the one with the most headroom.
Post-purchase. The most under-used flow in ecommerce, by a mile. Your customer is at peak enthusiasm. They’ve just bought, they’re waiting for the box, they’re checking the tracking. Most brands use that window to send a shipping notification and nothing else. That’s a wasted moment. That’s where the second order gets built.
Winback. They bought once, then went quiet. They already know you and already trust you enough to have paid you. Reaching them is a fraction of the cost of finding someone new, and yet nine out of ten brands are spending more to acquire a stranger than to recover a customer.
That’s the core. Get those four right before you build anything clever.
SMS is not email with fewer characters
Quick note, because this is where brands burn a good channel.
SMS is the most intimate channel you have. It lands next to messages from their family. That gives it extraordinary open rates, and it gives you exactly one chance to abuse it before you’re deleted forever.
Use it for the moments that are genuinely time-sensitive and genuinely useful: the checkout that’s about to expire, the restock they asked to hear about, the delivery that’s arriving today. Don’t use it to announce a sale for the fourth time this month.
Treat it like a text from a friend, not a billboard with your phone number on it.
Where to start if you have nothing
Don’t build the perfect programme. Build the four flows above, one at a time, in that order, and get them live.
Then go and look at your repeat purchase rate, the percentage of customers who buy more than once, and write the number down. It’s the number that tells you whether you’re building an asset or renting one, and it’s the one number I’d bet you can’t currently quote off the top of your head.
If it’s under 20%, you don’t have a traffic problem. You have a bucket problem.
Retention is almost always the cheapest lift available to a brand, and it’s almost always the last thing anyone looks at.
