Walk into any CMO’s office this quarter, and you’ll find a stack of vendor proposals built on 12-month payback periods, with vendors quite confident about year one and a little less sure about year three. This is where a successful pilot turns into technical and operational debt.
The agentic commerce pitches start to blur together. One rewrites the funnel, another consolidates the stack, and a third replaces tools the CMO bought 12 months ago. The acronyms are in place (UCP, MCP, A2A, etc.), and the demos are impressive. But like any emerging category, there are big unknowns: acquisitions, evolving protocols, and pricing changes that can upend a three-year roadmap.
To evaluate these investments, it helps to look at a channel that has already survived decades of technological disruption: direct mail.
Unfashionable as it may be to say, direct mail will outlast most of the agentic commerce startups pitching you today. That’s a strange thing to say in a year when AI agents influenced 20% of all Cyber Week orders in 2025 and drove an estimated $67 billion in global sales, according to Salesforce. The capability is real, and so is the money behind it.
Direct mail, meanwhile, was supposed to die when email arrived, then again for banner ads, programmatic, social, and retail media. It’s still in the budget, having survived four rebuilds of everything around it.
Despite all the attention-grabbing headlines to the contrary, direct mail endures because brands own what makes it work. That’s a useful test for every agentic commerce investment you’re considering today.
Direct mail has survived because brands own the assets, focus on durable functions, and measure results consistently. Those same characteristics provide a useful framework for evaluating agentic commerce investments.

1. The brand owns the asset base
Direct mail runs on infrastructure unlikely to be disrupted anytime soon, since postal addresses are a public utility. Customer files, response history, and accumulated knowledge of what works for a particular audience grow more valuable over time. All of it stays with the brand.
Most of the past decade in digital offered a slow (and expensive) lesson in how little of the underlying infrastructure brands actually own, and how that lack of ownership translates into revenue for the platforms that claim it first.
In contrast, ad inventory is rented from platforms whose auction logic changes frequently. Audience access is rented from networks that have narrowed targeting more than once, often with little transparency. Marketers lived through the “end” of third-party cookies, the ATT, and the decline of organic reach across social platforms.
Now they’re being asked to build commercial infrastructure for agentic commerce. Protocols evolve, LLMs change, and many companies are still searching for sustainable profitability. The data clauses often resemble the social media contracts signed in 2011 when that industry was still in its infancy.
Marketing teams need to ask tough questions during platform demos so they understand where they stand if a vendor pivots, protocols change, or another technology disruption emerges.
Structured first-party data and know-how that can move to another system qualify as assets worth investing in. Vendor lock-in and high switching costs, however, can outweigh any early gains, even if they help beat competitors to market.
2. The function provides a strong foundation for new formats
Direct mail evolved from simple beginnings to include postcards, self-mailers, catalogs, dimensional packages, variable-data print keyed to CRM segments, Informed Delivery previews, and even QR codes that drop you into an email sequence.
While the delivery mechanism may evolve every few years, the underlying purpose doesn’t. Direct mail delivers an addressable message to a known household and measures the response. That held true in 1968 and will likely hold true in 2035.
Many newer marketing investments follow the opposite pattern, where format leads and function remains unclear, especially as specifications, industry alliances, and technologies continue to change. Chatbots became conversational AI, then copilots, then agents, then agentic workflows, and each shift triggered another procurement cycle.
By 2030, AI itself may fade into the background, as the information superhighway did. If so, platforms whose primary strength is artificial intelligence will need to demonstrate tangible value beyond the label.
Teams that went all in on the 2017 chatbot wave can rarely point to a single capability that survived every rebrand. They can point to four purchases, each of which was eventually replaced.
Gartner expects more than 40% of agentic AI projects to be canceled by the end of 2027, citing escalating costs, unclear business value, and weak risk controls. The firm also estimates that only about 130 of the thousands of self-described agentic vendors are the real thing. The rest are agent washing, attaching the label to older assistants, and decades-old robotic process automation (RPA).
Require vendors to describe their product in terms of a core job that remains necessary even if the underlying model, interface, and delivery mechanism change completely within three years.
For example, “Representing our offer accurately in machine-mediated buying environments” is a durable function. “Orchestrating multimodal generative experiences across the omnichannel surface” is a format masquerading as a function.
Buying new technology is often the right call. The discipline lies in identifying work you’d still need done if the platform disappeared overnight. Direct mail vendors answer that question without hesitation. The agentic vendors who can usually deserve your attention.
3. Consistent measurement enables steady improvement
Direct mail measurement evolved gradually while everything around it churned. With direct mail, the list, offer, date, cost, and response window are known entities. Testing relies on a control cell, and marketers have measured incremental response the same way for at least 40 years.
Digital advertising and engagement, by contrast, never achieved the same stability. Click attribution gave way to engagement, engagement to attention, attention to incrementality, and somewhere along the way, media mix modeling came back from the dead. Each wave arrived with new vocabulary and the suggestion that the previous approach was naïve. Agentic vendors now sell “agentic ROI” and “outcome attribution,” terms that vary by platform and may not survive this fast-changing environment.
When evaluating an agentic commerce platform, look beyond ease of implementation and consider how benchmarks and metrics will hold up over time. In a setup where agents handle discovery, recommendations, and checkout, and brands appear wherever agents steer shoppers, two questions help determine whether you’re making a long-term investment or renting short-term results:
- What does the brand keep? This may include product data, interaction history, and negotiation policies that can be migrated to another system and remain as owned assets. Contrast that with configurations locked inside a vendor’s platform.
- What questions will it still answer in 2029? “Did the agent’s recommendations lift qualified conversion against a holdout?” is a valuable question. Achieving a high score on a vendor’s proprietary index is not.
Answering these questions helps determine whether an investment is durable or whether contract terms should reflect a more temporary arrangement while additional build-versus-buy scenarios play out and the market matures.
If a platform’s core capability is valuable but the surrounding infrastructure remains rented, renegotiating the scope of an initial procurement to secure greater long-term ownership may prove more strategic than accepting the original terms or walking away and allowing competitors to gain a short-term advantage.

Considerations for the months ahead
Between pressure to keep pace with competitors and rising customer expectations, the appeal of early adoption is obvious. Even so, inaction may cost less than rushing onto an unstable foundation. The greater discipline lies in maintaining coherence while moving quickly, because speed on a rented foundation only accelerates the need for migration.
Before the next contract or renewal, define the version of this capability you expect to operate in 2029. If that vision includes assets, knowledge, and measurement that belong to the brand rather than the vendor, the investment can compound over time. If you can’t define those owned assets, you’re likely buying a short-term feature with a lifespan of 12 months or less, and the contract should reflect that reality.
Vendors will continue marketing future innovations. The strategic choice is to define what you intend to own and invest accordingly.
