The Difference Between an Email Marketer and a Retention Marketers
TL;DR: Most people talking about retention marketing are actually talking about retention tactics. Email, SMS, loyalty programs, subscriptions, rewards, replenishment campaigns, and repeat purchase rates are not retention—they’re tools used to influence it. The fundamental difference between an email marketer and a retention marketer is that email marketers optimize communications, while retention marketers optimize customer commitment across the entire business. True retention is the art and science of turning customers into communities by helping them succeed with your product, connect with your brand’s ecosystem, expand the value they receive, and ultimately become advocates. The brands that win long-term don’t simply send better campaigns; they create experiences and communities that customers don’t want to leave.

What The F**K is Retention Marketing?
Over the last two years, I’ve watched something fascinating happen.
Thousands of email marketers magically became retention marketers.
Almost overnight.
One day they were talking about subject lines, segmentation, click-through rates, and welcome flows.
The next day they’re posting about retention strategy, customer lifetime value, loyalty economics, and customer experience.
It’s a remarkable transformation.
In fact, if LinkedIn is to be believed, there are now approximately 47 million retention experts in ecommerce.
Most of whom have never owned retention.
Most of whom have never been responsible for customer service.
Never touched product onboarding.
Never managed loyalty.
Never influenced merchandising.
Never owned customer experience.
Never sat in executive meetings where retention wasn’t a channel metric but a company-wide operating system.
Now, before the email marketers get angry, let me be clear:
Email is incredibly important.
SMS is incredibly important.
I built my career around them.
My company has generated hundreds of millions in revenue through email and SMS programs.
The problem isn’t email.
The problem is confusing a channel with a business function.
That’s like confusing Facebook Ads with growth.
Or confusing customer service with customer experience.
Or confusing inventory with operations.
They’re connected.
But they’re not the same thing.
An email marketer optimizes communications.
A retention marketer optimizes customer commitment.
That single distinction changes everything.
Because when you understand retention properly, you realize it has very little to do with sending more campaigns and everything to do with creating reasons for customers to stay.
And that’s where most of the ecommerce industry gets it wrong.
The Great Retention Delusion
Ask ten ecommerce operators what retention means and you’ll get ten different answers.
Some will tell you retention is subscriptions.
Others will tell you retention is loyalty programs.
Others will tell you retention is replenishment flows.
Others will tell you retention is repeat purchase rate.
Others will tell you retention is reducing churn.
None of those definitions are entirely wrong.
But none of them are entirely right either.
Because they’re describing symptoms.
Not the system.
Retention isn’t a tactic.
Retention isn’t a channel.
Retention isn’t a metric.
Retention is the outcome of a well-designed customer experience.
That’s a fundamentally different way of thinking.
Let’s use an example.
If a customer purchases a protein powder subscription for twelve months, have you retained them?
Maybe.
Or maybe they’ve simply forgotten to cancel.
If a customer buys from you four times because you’re constantly discounting products, have you retained them?
Maybe.
Or maybe you’ve trained them to only purchase when there’s a promotion.
If a customer joins your loyalty program, have you retained them?
Not necessarily.
You may have simply collected another email address.
Real retention isn’t measured by what customers do.
It’s measured by why they do it.
That’s where most brands stop digging.
What Billion-Dollar Brands Actually Understand
I spent years studying and working alongside brands operating at scales most ecommerce businesses never reach.
And one thing became very clear.
The best brands never viewed retention as a marketing department.
Retention was a company-wide responsibility.
Marketing influenced retention.
Customer service influenced retention.
Operations influenced retention.
Product influenced retention.
Merchandising influenced retention.
Packaging influenced retention.
Community influenced retention.
Everything influenced retention.
Because retention wasn’t defined by a campaign.
It was defined by a customer’s willingness to continue the relationship.
That’s a much bigger objective.
When you think this way, email becomes one piece of a much larger machine.
An important piece.
But still just a piece.
The Real Definition of Retention
After working with more than 160 brands and serving as VP of Retention, I’ve arrived at a simple definition:
Retention is the art and science of turning customers into communities.
That’s it.
That’s the game.
Most businesses think they’re selling products.
The best businesses understand they’re building belonging.
Products create transactions.
Communities create commitment.
Products create purchases.
Communities create identity.
Products solve problems.
Communities solve loneliness.
And identity is one of the strongest economic moats a business can build.
Because people leave products all the time.
People leave software.
People leave stores.
People leave subscriptions.
People rarely leave communities they genuinely identify with.
The strongest retention strategy in the world isn’t another automation.
It’s creating an environment customers don’t want to leave.
Why Most Retention Strategies Fail
The average retention strategy begins with a second purchase.
That’s already too late.
Most brands start asking:
“How do we get them to buy again?”
The better question is:
“How do we make sure they succeed?”
Because customer success drives customer retention.
Not customer reminders.
The strongest predictor of future purchasing behavior is whether customers received the outcome they expected.
Not whether they opened your email.
Not whether they clicked your SMS.
Not whether they joined your rewards program.
Did they win?
Did they solve the problem?
Did they achieve the transformation?
If not, nothing else matters.
Which brings us to the first stage of real retention.
Stage One: Adoption
Adoption is where retention actually starts.
Not after thirty days.
Not after sixty days.
Not after the second purchase.
Immediately.
The moment someone gives you money, they begin evaluating whether they made a good decision.
Your job is to eliminate buyer’s remorse as quickly as possible.
That requires much more than email.
It requires:
Product education.
Customer support.
Packaging.
Unboxing experience.
Onboarding.
Content.
Community.
Expectations management.
Every interaction either increases confidence or creates friction.
And friction kills retention.
The goal of adoption is simple:
Help customers achieve success as quickly as possible.
Because successful customers stay.
Unsuccessful customers churn.
Everything else is secondary.
Stage Two: Retention & Belonging
Once customers experience success, something interesting happens.
They’re no longer evaluating the product.
They’re evaluating the relationship.
This is where community becomes important.
Not because community sounds trendy.
Because community creates identity.
The best brands give customers access to something bigger than the transaction.
A community.
A movement.
An identity.
A lifestyle.
A shared mission.
A shared challenge.
A shared aspiration.
This is why Peloton isn’t just selling bikes.
Why CrossFit wasn’t just selling workouts.
Why Harley-Davidson isn’t just selling motorcycles.
People don’t stay because of products.
People stay because of who they become.
Stage Three: Expansion
Most brands misunderstand expansion.
They think expansion means upsells.
That’s a very narrow view.
Expansion is about increasing value.
Sometimes that means another product.
Sometimes it means education.
Sometimes it means services.
Sometimes it means relationships.
The question isn’t:
“How do we sell more?”
The question is:
“How do we help customers get more value?”
That’s a completely different mindset.
And ironically, it usually creates more revenue.
Because value creates trust.
Trust creates purchasing behavior.
Stage Four: Advocacy
Advocacy is the highest expression of retention.
It’s when customers begin contributing back.
Reviews.
Referrals.
Testimonials.
User-generated content.
Feedback.
Community participation.
Most brands view advocacy as a marketing asset.
The best brands view advocacy as proof of belonging.
When customers voluntarily invest in your success, you’ve crossed an important threshold.
You’re no longer a vendor.
You’re part of their identity.
And identity is incredibly difficult for competitors to steal.
The Metrics Most Brands Should Be Measuring
Here’s another unpopular opinion.
Most retention dashboards are terrible.
They focus on lagging indicators.
Repeat purchase rate.
Customer lifetime value.
Revenue per recipient.
Useful metrics.
But they tell you what happened.
Not what’s happening.
The best retention operators monitor leading indicators:
Product adoption rates.
Time-to-value.
Customer satisfaction.
Community participation.
Account creation.
Content consumption.
Review generation.
Referral behavior.
Advocacy signals.
These metrics reveal future retention before financial reports ever do.
The Economic Power of Community
The reason retention matters isn’t because repeat purchases look good in a spreadsheet.
Retention matters because it changes the economics of your business.
Better retention lowers customer acquisition pressure.
Better retention improves cash flow.
Better retention increases lifetime value.
Better retention improves profitability.
Better retention creates referral loops.
Better retention compounds.
Acquisition rents growth.
Retention owns growth.
That’s the difference.
The businesses that dominate categories over long periods almost always have stronger retention systems than their competitors.
Not necessarily better marketing.
Not necessarily bigger budgets.
Better systems.
The Future of Retention
The ecommerce industry is entering a period where acquisition is becoming increasingly expensive.
Attention is fragmented.
Competition is increasing.
Customer expectations are rising.
Brands can no longer rely on acquisition alone.
The winners of the next decade won’t simply be the brands that acquire customers most efficiently.
They’ll be the brands that create the strongest customer commitment.
That’s why retention isn’t a marketing trend.
It’s an operating philosophy.
And that’s why I laugh when I see people suddenly rebrand themselves as retention marketers after spending years exclusively managing campaigns.
Because retention isn’t something you do inside Klaviyo.
Retention is something that happens across your entire business.
Email matters.
SMS matters.
Subscriptions matter.
Loyalty matters.
They’re all important.
But they’re all tactics.
Retention is the system.
The art.
And the science.
Of turning customers into communities.
And the brands that understand that distinction will outperform the ones that don’t for the next decade.
