Solving Customer Acquisition Costs (CAC) Challenges: From Paid Media Over-Reliance to Multi-Channel Success

Are you struggling with rising customer acquisition costs (CAC), often relying heavily on paid media to drive growth?

While paid advertising can be an effective tool, an over-reliance on it creates vulnerabilities: higher costs, diminishing returns, and dependence on unpredictable platform changes. To build a more sustainable and profitable model, brands must diversify their acquisition strategies in smarter, more integrated ways.

We spoke with Power Digital’s fashion marketing experts: Lilly Fuhrman, Senior Account Director; Hanna Lane, Group Director; and Madison Sternberg, Account Director; who shared their insights on the pitfalls of paid media dependence and how brands can successfully transition to a multi-channel strategy.

Paid media can be a powerful driver of customer acquisition, but when brands rely on it too heavily, they put themselves at risk.

“It makes you at the mercy of the platforms,” Sternberg explains. “During competitive periods, you’re even more impacted by rising CPMs, which will automatically hurt deliverability and ultimately sales. Or if you’re relying heavily on a platform like TikTok, which may suddenly be banned, you’re left scrambling.”

 

Beyond cost volatility, Lane highlights a common misconception among brands. “A lot of brands assume that if overall e-commerce is growing, they should be growing too,” she says. “But is that industry growth coming from brands like yours? Or is it being driven by fast-fashion giants like Shein and Temu?”

Additionally, Lane warns that focusing too much on paid media can create an internal issue. “It leads to a damaging mindset where brands think paid is responsible for everything. This can cause over-scrutinization of paid efforts instead of looking at the bigger picture.”

Breaking free from paid media dependence requires brands to diversify their customer acquisition strategies, but not through guesswork or channel dumping.

A successful transition is not about adding more channels. It is about creating a connected ecosystem where each touchpoint amplifies the others.

“A phased approach is key,” Fuhrman advises. “Rather than cutting off paid media, brands should gradually invest more in owned and earned channels while refining their audience strategy.”

Lane adds that even if Power Digital is not managing a brand’s organic channels directly, the team consistently consults on cross-channel strategies. “We’ll notice if lifecycle marketing is down and suggest retention-focused adjustments, even if that’s not in our scope. The key is ensuring that brands do not rely on paid alone to sustain growth.”

This type of cross-functional awareness is what actually helps CAC stabilize. It is not simply turning on SEO or doing more email. It is aligning channel roles, ensuring measurement is consistent, and making sure paid is not compensating for gaps elsewhere.

If brands are looking to reduce CAC while maintaining growth, they need to invest in alternative acquisition channels in a more intentional and operationally aligned way. Below are the three areas our experts say deliver the biggest impact, and what it looks like in practice.

“Even if we are not managing organic, we always look at how it supports paid efforts,” Lane says. “For example, if a brand has strong organic rankings for certain keywords, we might advise pulling back ad spend on those terms and reallocating the budget elsewhere.”

She continues, “The best brands successfully leverage their lifecycle marketing efforts, using email, SMS, and retargeting, to increase customer retention without depending solely on paid acquisition.”

What this looks like in action:

Sternberg emphasizes that brands need to rethink their media mix. “SEO, influencer marketing, and even out-of-home advertising can provide additional touchpoints. Customers do not just exist on Meta and Google. They are engaging with content in different ways and need multiple touchpoints.”

How top-performing brands execute this:

Lane highlights the importance of understanding customer behavior. “Brands that effectively segment their audiences can target different groups with tailored messaging based on first-party data about their actual buyers. New customers.”

Where segmentation moves the needle:

Diversifying customer acquisition is not about abandoning paid. It is about creating a multi-channel system where paid becomes more efficient, less volatile, and better supported.
