AdWaste Crisis
Consumer businesses face an existential threat: skyrocketing customer acquisition costs (CAC). While performance marketing through adtech platforms promises quick results, it has created a toxic dependency. CAC increases 20-25% annually through auction-based platforms, straining marketing budgets and profitability. This upward spiral forces brands into an unsustainable cycle of spending more to maintain growth.
The spending breakdown reveals a troubling pattern that undermines business economics:
- 10% on retention (existing customers)
- 20% on genuine first-time acquisition
- 70% on reacquisition – the true “AdWaste”
This reacquisition spend goes toward winning back lapsed, dormant, or inactive customers time and again. These second-, third-, or nth-time acquisitions are truly the “AdWaste,” because in a more ideal world, marketers should not have to pay repeatedly to reach their own customers. Repeatedly paying to reach customers already in the database represents marketing’s cardinal sin. When brands have customer email addresses, phone numbers, and purchase histories, why must they rent access to these same customers through expensive intermediaries?
This wasteful cycle stems from three fundamental failures in modern marketing:
- The “No Hotline” Problem: Despite having contact details, brands lack reliable engagement channels. Email open rates languish in single digits, push notifications get blocked, and SMS lacks depth. Without a dependable way to reach customers, brands resort to paid advertising for basic communications.
- The “Not for Me” Problem: Generic messaging ignores individual preferences, driving customers into dormancy. Mass communications feel irrelevant or intrusive. Without personalisation, even interested customers become unreachable without paid ads. This creates a vicious cycle where poor engagement forces more ad spending.
- The “No Alternative” Problem: Brands see no option besides expensive adtech platforms for reactivation, perpetuating their dependency on Google and Meta. The auction-based pricing of these platforms means costs only increase over time, yet brands feel trapped without viable alternatives.
The consequences of this broken system are severe and far-reaching:
- Eroding profits as CAC outpaces revenue growth
- Under-monetised customer relationships
- Diminished lifetime value (LTV)
- Weakened loyalty and advocacy
- Reduced resources for product innovation and customer experience
- Unsustainable unit economics
As Fred Reichheld notes, true loyalty comes from consistently positive experiences that make customers “come back for more and bring their friends.” By failing to nurture existing relationships, brands waste their most valuable asset—customers who already trust them enough to buy. Instead of investing in deeper engagement and better experiences, they pour resources into repeatedly reacquiring the same customers.
However, a revolution in email marketing promises to break this cycle. By transforming email from a one-way broadcast medium into an interactive engagement channel, brands can simultaneously generate new revenue streams (“print money”) and reduce reacquisition costs (“save money”). This paradigm shift could finally enable sustainable, profitable growth without the AdWaste tax.
The key lies in reimagining email as more than just a communication tool—it must become a robust platform for engagement, commerce, and monetisation. Through innovations in personalisation, interactivity, and authenticated advertising, emails can evolve into the primary hotline between brands and customers, eliminating the need for costly reacquisition while creating new opportunities for value creation.
