Rachel Wilkie has led digital marketing for billion-dollar brands and product lines, including MAC, Estee Lauder, and Harry Potter, and she’s done GTM for startups. Here’s what she’s learned about scaling D2C profitably while protecting margin.

The ROAS Problem Preventing Profitable D2C Growth

Most direct-to-consumer brands celebrate hitting 150-200% return on ad spend. They’re pouring budget into Meta and TikTok, optimizing creative, and wondering why they can’t scale D2C profitably past that ceiling.

Rachel Wilkie managed a $27 million digital marketing budget at Merrell and achieved 300% ROAS—double what most D2C brands consider successful. The difference wasn’t more budget or better targeting. It was letting go of something most marketing teams hold too precious.

D2C ROAS Optimization: Stop Being Precious About First Impressions

The problem isn’t your creative—it’s treating every ad like a pristine brand moment that prevents D2C ROAS optimization.

“So many teams treat it like it’s super precious,” Rachel Wilkie explains. “Like ‘oh this is the first impression people have of our brand, it has to be on point.’ But I think one thing that TikTok has taught us is that sometimes a first impression—like controversial even—brings a consumer in for more questions or curiosity.”

The breakthrough comes from understanding that the first impression gets them in the door. The experience after that is what keeps them coming back—and what allows you to scale D2C profitably.

Meta, in particular, is a beast to feed. The platform rewards diversity in creative—different formats, different hooks, different audience segments. But if you’re bottlenecking every piece of creative through brand approval processes and perfectionism, you can’t feed the algorithm fast enough to drive profitable D2C growth.

Rachel’s recommendation for D2C ROAS optimization: creative automation templates. “It’s so easy actually to get a whole MCP agent going to fill in templates with assets. I think that’s the way to manage those platforms now.”

The competitive landscape has exploded with AI tools making it easier than ever to launch e-commerce sites. You need diversity in content to reach different consumer groups. Meta highly rewards that. If you’re too precious about brand guidelines, it will cost you massive opportunity to scale D2C profitably.

The playbook to improve D2C ROAS:

• Build creative automation systems that scale
• Test controversial or curiosity-driven hooks (not just polished brand moments)
• Prioritize volume and diversity over perfection
• Let the algorithm reward what works, kill what doesn’t

E-Commerce P&L Ownership: Why It Supports Profitable Growth

Most CMOs are measured on top-line growth—traffic, conversions, revenue. Rachel Wilkie owned full P&Ls for brands doing $300M at MAC and $110M+ at Merrell. When you’re accountable for both revenue AND margin, every decision changes—and you learn how to scale D2C profitably instead of just scaling.

Revenue at All Costs Prevents You From Scaling D2C Profitably

“So many companies get this wrong at the executive leadership level where it is just a push on revenue at all costs,” Rachel says. “And what does it take to push revenue? Spend. Spend. Margin attrition. And that is directly against profit.”

When CMOs aren’t accountable for the P&L, they optimize for vanity metrics—clicks, impressions, even revenue—without understanding the impact on contribution margin and EBITDA. Rachel grew up in e-commerce with P&L responsibility from day one, which gave her fundamentally different insights on how to spend marketing dollars to drive profitable D2C growth.

E-Commerce Attribution Strategy: More Than Last-Click

GA4 gives you last-click attribution. But that’s not where customers actually discover your brand—and it’s not how you scale D2C profitably.

Rachel Wilkie’s approach: ask post-purchase questions. Where did you first hear about us? What made you decide to buy today? Hearing directly from customers gives you insights that attribution tools miss entirely.

“I think attribution is really important in understanding not just last click with GA4 but also where are customers learning about you. Where are they discovering your brand.”

The decision-making framework for profitable D2C growth shifts based on business needs:

• Revenue season: Flex up marketing as percent-to-total, prioritize growth
• Profit season: Dial down spend, tighten to the most ROAS-efficient channels

But you need clear objectives from leadership to make these trade-offs intelligently. Without e-commerce P&L ownership, CMOs default to spending more—because that’s the only lever they control. That’s how you burn margin instead of scaling D2C profitably.

D2C Retention Strategy: Stop Flooding Customers

Churn is the silent killer of D2C brands trying to scale profitably. You’re acquiring customers at $50-$100 CAC, they buy once, and they disappear. Rachel’s been talking to brands about the same D2C retention strategy mistake for over a decade—and most still haven’t fixed it.

More Messages Don’t Equal Better D2C Retention

“Most brands think about retention in terms of sending more communications and making sure that you’re constantly top of mind,” Rachel Wilkie explains. “But it’s not. It’s actually about sending fewer messages with higher intent.”

The D2C retention strategy unlock: make every communication relevant to the customer. Don’t flood them with generic promotions or product launches they don’t care about. This requires ruthless prioritization of what categories matter most to your customer—and the operational discipline to segment accordingly. This is how you scale D2C profitably without constantly replacing churned customers.

Why don’t more brands implement this D2C retention strategy? Because it’s operationally difficult.

“You have to really have templatization and you have to have ruthless prioritization of what the categories are that are most important to your consumer. Without those two things, it’s so difficult for lean teams.”

Rachel’s retention ecosystem at Merrell included SMS segmentation and product bundles that became core revenue streams—not just retention tactics. The key was building an asset engine that could support highly segmented communication at scale.

The D2C retention strategy playbook:

• Fewer messages with higher relevance beats constant communication
• Templatize communications so segmentation is scalable
• Ruthlessly prioritize the 3-5 categories that matter most to your customer
• Build the asset engine (creative, copy, offers) to support segmented messaging

If you can’t operationalize segmentation, you’ll never achieve the level of personalization required to retain customers and scale D2C profitably.

Shopify Replatform Strategy: How to Launch in 6 Months Without Breaking Everything

Rachel Wilkie replatformed to Shopify and launched an in-house e-commerce conversion rate optimization engine in under 6 months. Most companies take 12-18 months and burn millions trying to preserve every feature from their old platform—the opposite of scaling D2C profitably.

The Shopify Replatform Strategy Secret: Cut Ruthlessly

“A lot of platforms fail because they’re trying to preserve decisions made in prior platforms,” Rachel says. “Trying to maintain the functionality of something you once had is crippling.”

The wrong question: What features did we have on the old site that we need to rebuild?

The right Shopify replatform strategy question: What do customers actually need on the new site? What problems are we solving for them?

Rachel’s approach: strip down to an MVP focused entirely on what benefits the customer. Get live on Shopify, then use Shopify’s speed and flexibility as a catalyst for future enhancements. Don’t try to rebuild everything on day one.

“Shopify is a catalyst for future enhancements and growth because you can move so much faster than a lot of the platforms I’m replatforming away from—like Magento, WooCommerce, BigCommerce.”

The Shopify replatform strategy playbook:

• Define MVP based on customer needs, not internal wish lists
• Cut everything that isn’t essential to a great customer experience
• Get live fast, then iterate rapidly post-launch
• Use Shopify’s agility as an advantage, not a constraint

Rachel has replatformed over 300 businesses using this approach. The brands that scale D2C profitably are the ones willing to let go of legacy functionality that no longer serves the customer.

E-Commerce Conversion Rate Optimization: From 3 Tests to 40 Tests Per Month

Most D2C brands run 2-3 A/B tests per month. Rachel Wilkie established e-commerce conversion rate optimization programs running 20-40 tests per month. The difference in revenue impact—and your ability to scale D2C profitably—is staggering.

Why Scale E-Commerce Conversion Rate Optimization Testing?

“When you’ve got traffic coming into your site and people leave and conversion rate is so low for almost every brand—especially with a higher AUR product—you’re literally leaving money on the table. You’re just bleeding out money.”

Think about every dollar spent to drive traffic to your site. If you can increase conversion rate by even 1% through e-commerce conversion rate optimization, that’s a massive revenue impact on a $100M business. Every bit of the experience counts when you’re trying to scale D2C profitably.

But scaling to 40 tests per month requires the right tech stack and the right culture.

The Tech Stack That Enables E-Commerce Conversion Rate Optimization at Scale

Most CRO tools like Optimizely don’t allow you to run many tests simultaneously—you split traffic too many ways and lose statistical confidence. Rachel Wilkie’s solution: move to a headless environment.

“When you move to a headless environment, you can actually start to truly split the traffic and run tests outside of Shopify’s black box because the headless site essentially sits on top of the Shopify backend.”

The headless architecture allowed Rachel’s team to run tests, identify winners, and turn them on permanently—all within the same sprint. This is the e-commerce conversion rate optimization infrastructure that lets you scale D2C profitably.

The E-Commerce Conversion Rate Optimization Flywheel in Action

Out of 40 tests, maybe 5 win. If you’re only running 3 tests per month, it takes 6 months to get 5 winners. That’s hard to see meaningful impact—especially because some tests take you backwards during that time.

Rachel’s mantra: fail fast, fail forward.

“That flywheel—when you’re like ‘oh there’s 5 test wins here, we’re turning them all on, we’re pivoting these 3 tests and we’re shutting off the rest’—that’s basically how it was every sprint.”

Stack that month over month, and in 4 months you have 20-30 meaningful improvements to customer experience instead of maybe one. This is how you scale D2C profitably through systematic optimization.

What Rachel Wilkie tested for e-commerce conversion rate optimization:

• Product discovery paths (helping customers find what they didn’t know you offered)
• Cross-category recommendations (what people also bought from)
• Repeat purchase drivers (pens at Rifle Paper Co., earrings at Alex and Ani)

The insight: if you have a customer that buys multiple categories, there’s much higher propensity they’ll come back. Some products have higher repeat rates than others—test to find them, then optimize discovery. This directly impacts your ability to scale D2C profitably.

The e-commerce conversion rate optimization playbook:

• Invest in the right tech stack (headless if you want 20+ tests)
• Build a team that’s curious, motivated, and willing to take chances
• Fail fast—turn off losers, turn on winners, move forward
• Focus on product discovery (customers can’t buy what they can’t find)

What legacy brands get right about product strategy that smaller DTC-native brands miss —and vice versa

Rachel Wilkie’s career spans both worlds: billion-dollar beauty brands (MAC, Estée Lauder) and scrappy D2C startups. She’s worked on licensed product lines (Harry Potter, Disney, Barbie) and D2C exclusives that scaled from $200K to $16M profitably.

Legacy Brands Win on Collaboration—But Lose on Speed

Legacy brands have an easier path to licensing and collaborations. When you’re MAC or Estée Lauder with a $14 billion portfolio, you can command the room. Licensing partners come to you.

But that advantage can backfire if you’re not strategic. Rachel Wilkie remembers pulling back a Cruella de Vil launch at MAC because PETA was protesting animal testing in cosmetics—it would have been a PR nightmare.

“The decision isn’t really ‘should we do it.’ It’s making sure that you’re partnering with the right licensing partners, the right collaborations, the right people who are going to resonate with your customer.”

The flip side: legacy brands don’t move fast enough. Getting a new product launch through a billion-dollar ecosystem means you miss market trends entirely. By the time a TikTok partnership gets approved, the moment has passed. This prevents them from scaling D2C profitably in fast-moving markets.

Smaller D2C Brands Win on Speed—How to Scale D2C Profitably Through Agile Partnerships

The advantage D2C brands have when trying to scale D2C profitably: they can move fast on consumer insights and find partnerships at their scale.

“That’s the advantage of smaller brands—if you really know your customer and have it dialed in, there’s so much opportunity to partner with small mom-and-pop businesses. People love rooting for them.”

Rachel’s examples from Merrell (a legacy brand that acted scrappy to scale profitably):

• Local artist collaboration: Rainbow Mountains artwork on a best-selling silhouette—drove millions in weeks
• Dogfish Head brewery partnership: Customer insight showed trail runners loved beer—created a limited edition shoe that sold out immediately

The advantage D2C brands have: they can move fast on consumer insights and find partnerships at their scale. There’s no reason a small business can’t collaborate with local artists, breweries, or niche influencers to reach new audiences and scale D2C profitably.

The collaboration playbook to scale D2C profitably:

• Legacy brands: Be strategic about partnerships, move faster than your structure allows
• D2C brands: Use speed as an advantage, partner with small collaborators who resonate with your customer
• Both: Let consumer insights drive partnership decisions, not just what’s prestigious
