3 direct mail courses to test agency marketing

Walk into any CMO’s office this quarter, and you’ll find dozens of vendor proposals built around 12-month payback periods, with vendors most certain in the first year and less certain in the third year. This is where a successful pilot becomes a technical and operational liability.
Agent commercial spaces begin to blur together. One rewrites the funnel, another integrates the stack, and the third replaces the tools the CMO bought 12 months ago. The acronyms are there (UCP, MCP, A2A, etc.), and the demos are impressive. But like any emerging stage, there are big unknowns: acquisitions, evolving deals, and pricing changes that could shape the three-year road.
To evaluate this investment, it is useful to look at a channel that has already survived decades of technological disruption: direct mail.

Although it’s not fashionable to say, direct mail will outlast most of the marketing agent marketing startups sending you today. That’s staggering in a year where AI agents will influence 20% of all Cyber Week orders by 2025 and generate an estimated $67 billion in global sales, according to Salesforce. The talent is real, and so is the money behind it.
Direct mail, on the other hand, was supposed to die when email arrived, and it’s back to banner ads, programmatic, social, and retail media. It’s still on budget, having survived four rebuilds of everything around it.
Despite all the headlines to the contrary, direct mail endures because brands own what makes it work. That’s a useful test for every business investment you’re considering today.
Direct mail has survived because brands own assets, focus on solid operations, and consistently measure results. Those common features provide a useful framework for evaluating commercial investments.

1. The brand owns the asset base
Direct mail works and infrastructure is unlikely to be disrupted anytime soon, as postal addresses are a public service. Customer files, response history, and accumulated knowledge of what works for a specific audience become more important over time. Everything stays with the mark.
Most of the past decade in digital has provided a slow (and expensive) lesson in how little basic infrastructure products own, and how that lack of ownership translates into revenue for the platforms that want it first.
In contrast, the ad inventory used on social media whose auction logic is constantly changing. Audience access is employed by networks that have reduced targeting more than once, often with little transparency. Marketers have lived through the “end” of third-party cookies, ATT, and declining organic reach across social media.
Now they are asked to build a commercial infrastructure for the agent trade. Contracts are changing, LLMs are changing, and many companies are still looking for sustainable profits. Data clauses are often similar to social media contracts signed in 2011 when the industry was still in its infancy.
Marketing teams need to ask tough questions during field demos to understand where they stand if vendor pivots, protocols change, or other technical disruptions arise.
First-party structured data and information that can be migrated to another system qualify as assets to invest in. Vendor lock-in costs and high switching costs, however, may outweigh any early benefits, even if they help beat a competitor in the market.
2. The work provides a solid foundation for new formats
Direct mail evolved from simple beginnings to include postcards, self-mailers, catalogs, dimensional packages, dynamic data printing keyed to CRM segments, information delivery previews, and QR codes to throw in email sequences.
Although the delivery method may change every few years, the basic purpose remains the same. Direct mail delivers a customizable message to a known household and measures response. That was true in 1968 and will probably happen in 2035.
New marketing investments follow the opposite pattern, where the trajectory of format and function remains unclear, especially as information, industry alliances, and technology continue to change. Chatbots became conversational AI, then copilots, then agents, then agent workflows, and each transition started another buying cycle.
By 2030, AI itself may fade into the background, as does the information superhighway. If so, platforms whose core strength is artificial intelligence will need to demonstrate tangible value beyond the label.
Teams that have embraced every chatbot wave of 2017 rarely pinpoint a single skill that has survived across a brand. They can identify four items purchased, each of which has been replaced.
Gartner expects that more than 40% of AI projects will be canceled by the end of 2027, citing rising costs, unclear business value, and weak risk management. The company also estimates that about 130 of the thousands of self-described agent sellers are not genuine. Another is agent washing, labeling old assistants, and decades-old robotic process automation (RPA).
It requires vendors to define their product in terms of a core function that remains in demand even if the basic model, interface, and delivery method change completely within three years.
For example, “Representing our offerings accurately in machine shopping centers” is a long-term task. “Designing productive multimodal experiences across channels” is a format that does the job.
Buying new technology is often the right call. The discipline is to identify the work that will still need to be done if the platform disappears overnight. Direct mail marketers answer that question without a doubt. Agent sellers are often the ones who deserve your attention.
3. Consistent measurement allows for continuous improvement
The measurement of direct mail slowly evolved while everything around it was moving. For direct mail, the list, offer, date, cost, and response window are well-known organizations. The test depends on the control cell, and marketers have measured the response in the same way for at least 40 years.
Digital marketing and engagement, in contrast, have never achieved the same stability. The definition of clicks gave way to engagement, engagement in care, attention to growth, and elsewhere, media mix modeling came back from the dead. Each wave came with a new vocabulary and a suggestion that the previous method was absurd. Agency marketers now sell “agent ROI” and “result attribution,” terms that vary by field and may not survive in this rapidly changing environment.
When evaluating a commercial platform, look beyond ease of use and consider how benchmarks and metrics will hold up over time. In a system where agents handle acquisitions, recommendations, and payments, and products from wherever agents direct buyers, two questions help determine whether you’re making a long-term investment or hiring for short-term results:
- What does the brand store? This may include product data, interaction history, and chat policies that can be migrated to another system and remain as proprietary assets. Contrast that with a configuration locked within a vendor’s platform.
- What questions will we have to answer in 2029? “Did the agent’s recommendations increase qualified conversions versus foreclosures?” important question. Achieving a high score on the merchant identity index is not.
Answering these questions helps determine if the investment is solid or if contract terms should reflect a temporary arrangement while more build-versus-buy scenarios play out and the market matures.
If the stadium’s potential is significant but the surrounding infrastructure remains under rent, renegotiating the initial procurement rate to secure long-term majority ownership may seem more prudent than accepting the initial terms or walking away and allowing competitors to gain a short-term advantage.
Considerations for the coming months
Amid the pressure to keep up with competitors and rising customer expectations, the appeal of early adoption is obvious. Still, doing nothing may be less expensive than running into an unstable base. The main discipline lies in maintaining consistency while moving quickly, because the speed on the leased base only accelerates the need to migrate.
Before the next contract or renewal, define the version of this skill you expect to use in 2029. If that idea includes assets, knowledge, and scale that are not the product of the seller, the investment can be compounded over time. If you can’t describe those assets, you may be buying a short-term property of 12 months or less, and the contract should reflect that fact.
Vendors will continue to market new products to come. The strategy of choosing is to define what you intend to have and invest accordingly.
