Barbs Media explains why retention goes beyond sending more emails and shares its four-step process for helping ecommerce brands increase customer lifetime value through email and SMS.

What Clients Say About Barbs Media

Nick has done an amazing job on email for us. We're seeing 131% growth on the email revenue side. The flows are up over 90% in conversion value, which is dope.

In addition, he helped us increase our email revenue 3 400% just in Q4.

Immediately upon working with him, our email campaign revenue doubled.

I think that Nick Barbs builds a lot of trust and actually is interested in helping you.

I would highly recommend Barbs Media for your email marketing.

Making Every Customer Worth More

If you're running a seven- or eight-figure e-commerce brand, chances are you're spending a lot of money acquiring new customers. And a lot of your focus is going to go towards figuring out how to acquire more of them, whether that means improving your ads, lowering your CAC, or simply spending more.

But I think there's another side of the growth equation that a lot of brands aren't paying nearly enough attention to. And that question is: how do you make every customer you acquire worth more?

Because if you're spending tens or even hundreds of thousands of dollars every single month acquiring customers, but most of them buy once and disappear, you're putting a ton of pressure on your front end to keep growing the business. Every month, you need more traffic, more customers, more ad spend just to keep moving forward.

But if you can get more of those customers to come back, buy again, and become more valuable over time, the economics of your entire business start to change.

And that's exactly what this video is about. Not how to send more emails, but how to build a retention strategy that gets more value out of the customers you've already paid to acquire.

Our Retention Experience and Results

My name is Nick. I'm the founder of Barbs Media, and over the last several years, my team and I have helped more than 50 ecom brands improve retention. Our work has contributed to more than $50 million in email-attributed revenue.

For Gentiel Apparel, we generated nearly $500,000 in email revenue from a list of only 15,000 subscribers in a single year. For Petara Shoe, we increased email revenue 131% year-over-year within our first 90 days of working with them. For Potent Hockey, we increased email revenue by nearly 400% just in Q4.

But honestly, one of the numbers I'm most proud of is that the average client stays with us for 22 months. Because to me, that says a lot more than any short-term result ever could.

Email Marketing Is Not the Same as a Retention Strategy

With that said, I can honestly say that the brands getting the most out of retention aren't necessarily the ones sending the most emails. They're the ones that understand what needs to happen at each stage of the customer journey.

The problem is that once someone actually becomes a customer, the strategy usually gets a lot less sophisticated.

Let's say you have a few Klaviyo flows running, you send campaigns every week, and you have someone on your team managing email. All of that is important, but the thing is, having email marketing set up is not the same thing as having a strategy for increasing customer lifetime value.

Remember, the goal isn't just to generate more revenue from email. It's to get more value out of every customer you're already paying to acquire. That is how you fundamentally improve the economics of your entire business.

And this matters for a lot more than just email revenue. Because when customers buy once and disappear, you have to keep going back to paid acquisition to generate the next sale. And as acquisition gets more expensive—as we know, Meta is always increasing their ad prices—that puts more and more pressure on your margins.

Acquisition Is Only Half of the Growth Equation

Which brings me to the first big idea I want you to take away from this video: acquisition is only half of the growth equation.

Two brands can sell similar products, have similar margins, and even similar acquisition costs. But if one brand is significantly better at turning first-time customers into second-, third-, fourth-time customers, they're going to have a major advantage. They're getting more value from every customer they paid to acquire.

When every customer becomes more valuable, you can afford to spend more to acquire the next one. That's the whole name of the game. That gives you more room to scale your ads, compete for customers, and grow without completely destroying your margins, because you already know that your customers are worth more than theirs.

So, if you're only focused on lowering customer acquisition, you're only working on one side of the equation. Increasing what happens after you acquire the customer can be just as important, and it's truly limitless.

Retention Is Not Just About Sending More Emails

Which brings me to my next point. Like I said before, retention isn't about just sending more emails.

It's one of the biggest mistakes I see brands make. They know retention is important, so the solution becomes more campaigns, more flows, more promotions, more discounts. But before you decide what email to send, you need to understand what you're actually trying to change.

Maybe your biggest problem is that you're generating plenty of subscribers, but very few of them become customers. Maybe customers are buying once but not coming back for a second purchase. Or maybe they are coming back, but it's taking six months when realistically it could have happened in three. You could also be discounting customers who would have happily paid full price anyway.

And the thing is, these aren't email problems or email-specific problems. They're fundamentally strategic problems. Simply sending more emails is not going to solve them.

You need to understand what's actually preventing customers from buying again and then build your email and SMS strategy around solving that problem.

Your Back End Affects How Aggressively You Can Scale

And that brings me to my third point. Your back end affects how aggressively you can scale the front end.

Now, I want to be clear. Retention is not going to fix ad acquisition. If your product doesn't sell, your website doesn't convert, or your ads simply aren't working, better retention isn't magically going to solve those problems.

But once you've built an acquisition engine that works, eventually you start running into the economics of scaling it. And at that point, lowering your cost of acquisition isn't your only lever anymore. There's another side of the equation: increasing what each customer becomes worth after you acquire them.

Because the more value you can generate from the customers you're already acquiring, the more room you create to continue investing in acquisition.

Most brands spend the majority of their time trying to improve the front end. For us, we focus heavily on what happens after the customer is acquired, because when acquisition and retention are working together, you can build a much stronger growth engine.

Our Process: Diagnose, Strategize, Build, Optimize

So, how do we actually do this? Our process is pretty simple. Four parts. First, we diagnose, then we strategize, then we build, and then we optimize.

Firstly, we're going to look at your entire customer journey to understand where the biggest opportunities actually are. How are subscribers converting? How many customers come back? How long does it take for them to purchase again? And where are customers falling through the cracks?

Because every brand is different, and your retention strategy ultimately is going to reflect that.

Once the diagnosis is done, then we strategize. Once we know where the biggest opportunities are, we can build a roadmap around what needs to change and what we believe will have the biggest impact.

Once we strategize correctly, now is the time to build. That's where we actually execute the strategy through your flows, campaigns, segmentation, email, SMS, and everything in between.

And finally, we optimize. We continuously look at the data, what customers are responding to, what's working, and where the next opportunity is.

We're not just going to be sending emails. We're actually looking at how our customers are going to respond to that. We're constantly looking at the bigger picture of how we can make your customers more valuable over time.

Knowing What to Fix First

Now, the thing is, you might agree with everything I've just said. You know repeat customers matter. You know LTV matters. And you probably know there are things you could be doing better with retention.

But the harder part is knowing exactly what to fix. Where is the biggest opportunity in your business? What should you prioritize first? And what's actually preventing more of your customers from buying again?

Because the answer is going to be different for every brand. Without a clear strategy, it's very easy to spend months testing different flows, campaigns, offers, and everything without actually addressing the thing that's holding your retention back.

That's where having someone looking at retention from a strategic level becomes super valuable. And that's exactly what we do at Barbs Media. We're not just another email marketing agency trying to make your Klaviyo numbers look good.

Becoming a Genuine Growth Partner

We want to become an actual growth partner for your business. That means understanding the unit economics behind your business, your margins, your cost of acquisition, your average order value, your repeat purchase rate, your LTV, and ultimately what actually makes you more profitable.

Because generating more revenue from email means very little if we have to destroy your margins with discounts to do so. Ultimately, our goal is to understand how your business actually makes money, identify the biggest opportunities within your customer base, and then build a retention strategy around improving those economics.

Our Offer and Guarantee

So, here's our offer. If at any point you're not satisfied with the work we're doing, we'll refund every penny you've ever paid us. No complicated formulas or fine print.

We're not interested in locking brands into relationships that aren't working. We want to earn your business by becoming a genuine growth partner and focusing on what actually matters: building a stronger, more profitable business, not just making your Klaviyo numbers look better.
