Terence Tao: “Today there are a lot of very tedious types of mathematics that we don’t like doing, so we look for clever ways to get around them. But AIs will just happily blast through those tedious computations. When we integrate AI with human workflows, we can just glide over these obstacles. I also think mathematicians will start doing math at larger scales. Think about the difference between case studies and population surveys in sciences. If you were to study a disease in the 18th century, if it was a rare disease, you might study one patient who has this disease and record all their symptoms and take meticulous notes. But in the 21st century, you can do a clinical trial and you can administer a drug to 1,000 people and do statistics and get much more precise information about the efficiency of your drug. Mathematics is still very much at the case-study level. A paper will take one or two problems and study them to death in a very handcrafted, intensive way. That’s our style. But what AI tools enable is population studies.”

By 2025, that number had risen to five, and they were positioned higher up the table. “Chinese universities’ climbing in global rankings is real.

Greg Ip: “Technology enables us to produce more or better products with less hours of work. Over time, this makes us richer. It’s why we produce many times more food with far fewer farmers than 150 years ago and our factories crank out more products with a smaller workforce than in 1979. Technological advancements always cost some people their jobs—those whose skills can be easily substituted by tech. But their loss is more than offset through three other channels. The new technology enhances the skills of some survivors, who become more productive and better paid; it helps create new businesses and new jobs; and it makes some stuff cheaper, increasing consumers’ incomes, adjusted for inflation, which can be spent on other stuff, generating yet more jobs. These offsets explain why, through the sweep of U.S. history, technological advance hasn’t, by itself, raised unemployment for the country as a whole.”

NeoMails: The Attention and Monetisation Surface Brands Already Own (Part 12)

What Has to Be True for NeoMails to Win

NeoMails are a bet. A well-reasoned bet, with strong structural logic and early evidence behind it — but a bet nonetheless, on a new behaviour in a channel that has trained customers to expect very little. It is worth being clear-eyed about what has to be true for the bet to pay off.

The Open Must Be Earned, Not Forced

The entire architecture of NeoMails depends on the customer choosing to open — not out of urgency, not because the brand spent money on a subject-line optimisation tool, but because the email has earned a place in daily routine. That means the Magnet portfolio has to be genuinely good. Not adequate. Not acceptable. Good enough that a customer opens for the Magnet on days when they do not care at all about the brand.

This is an uncomfortable truth for marketers: the NeoMail must be worth opening even if it never mentioned the brand’s product. The brand is present — in the BrandBlock, in the from-line, in the Mu currency — but the primary reason to open cannot be the brand. It has to be the experience. Any dilution of Magnet quality in service of commercial messaging is a trade that costs more than it saves.

The Repeat Must Create Real Continuity

A single great NeoMail is marketing. A hundred consecutive NeoMails that each deliver something worth experiencing is a product. The distinction is everything. Marketing creates a moment; products create a relationship. The Mu mechanics, the streak system, the serial Magnet formats — all of these exist to make each NeoMail feel like a chapter in an ongoing story rather than a standalone send. If the continuity breaks — if the streak is not maintained, if Mu feels arbitrary, if the Magnet format is repeated too often — the habit breaks with it.

The hardest operational challenge in NeoMails is content velocity: the need to produce, rotate, and refresh Magnet content at a pace that prevents staleness while maintaining quality. This is a content production problem as much as a technology problem. It requires investment in Magnet formats, content pipelines, and quality benchmarks that most email teams are not currently structured to sustain.

The Trust Must Be Non-Negotiable

The inbox has a long memory. Every spam folder that filled up in the early 2010s was a collective customer verdict on brands that had violated trust. Every unsubscribe wave that followed each new email marketing trend was a market signal that customers had reached their limit. The inbox trust deficit is real and deep, and NeoMails are asking brands to ask for it back.

That requires the trust architecture to be not just adequate but exemplary. One ActionAd per NeoMail. No competitors. Brand-approved categories only. NeoMails-only unsubscribe that does not cascade to all brand communications. These are not features — they are the price of entry for a channel that customers have learned to distrust.

If NeoMails feel like a new form of adtech, they will die. If they feel like a genuine daily consumer product that happens to include one useful offer, they will become the most trusted regular email a brand sends.

The distinction between those two outcomes is made in dozens of small design decisions: how the ActionAd is placed, how the unsubscribe is handled, how the complaint rate is monitored, how quickly the kill switch is deployed. Trust is not built by policy; it is built by behaviour.

The Brands Must Shift Their Mental Model

Finally — and perhaps most difficultly — NeoMails require brands to change how they think about email. Not as a campaign channel to be optimised for individual send performance, but as a product to be built, sustained, and measured over a 90-day, 180-day, annual horizon. The metrics are different. The investment cadence is different. The success criteria are different.

The brands that get there first will build a structural advantage that is genuinely difficult to replicate: a daily, habitual, trusted presence in their customers’ inboxes, earning attention without paying for it, funding itself through inbox-native monetisation, and eliminating the AdWaste cycle that currently drains their marketing budgets every quarter. That is not a campaign result. That is a moat.

The Economics — How Broken Relationships Become Revenue

Attention without economics is art. NeoMails are designed to be a self-funding system — and at scale, a profitable one — without charging the brand for sending. The economics work across three distinct layers, each of which generates value independently and compounds when combined.

Layer One: ZeroCPM

The ActionAd inside each NeoMail generates revenue from a third-party partner. That revenue covers the cost of the send — making the channel economically neutral for the brand before any commercial outcome is achieved. This is ZeroCPM: zero cost because the emails pay for themselves. For a brand that currently pays for every email send regardless of engagement, this is a structural shift in the economics of owned-channel marketing. The owned channel stops being a cost centre and becomes, at minimum, cost-neutral.

At scale, ZeroCPM becomes a meaningful line in the marketing P&L — not just a mechanism for covering send costs, but a revenue stream in its own right, generated from the attention the NeoMails programme has earned.

Layer Two: Avoided Reacquisition Cost

Every dormant customer reactivated through NeoMails is a customer the brand does not need to buy back from Google or Meta. The avoided CAC is real, cashable value — money that does not appear in a revenue line but does appear in a CAC line that is materially lower. At any positive reactivation rate, at zero incremental cost, this is strictly better than the alternative of paying full market rate to re-acquire the same customer through paid channels.

The depth of this saving becomes clear when you consider what brands are currently spending on reacquisition. If 60-80% of ‘new customer’ spend is actually REACQ spend — as the data consistently shows — then a systematic reduction in that rate represents not a marginal improvement, but a restructuring of the marketing cost base.

Layer Three: The Global Prize

The full scale of the opportunity only becomes visible when you aggregate it. There are millions — globally, billions — of email addresses sitting in brand databases that have gone quiet. Not deleted, not opted out, simply silent. Each represents a broken relationship. Each represents a customer who was once commercially active and could be again.

If NeoMails can generate even one rupee per email ID per month in net value — through a combination of avoided REACQ cost, ActionAd revenue share, and incremental commercial activity from reactivated customers — the aggregate prize is staggering.

In India alone, a single email address typically appears across dozens of brand databases simultaneously. Aggregated across major consumer categories, the total count of brand-customer relationships sitting dormant in Indian databases runs to several billion — each one a connection that was once earned and is now silent. Globally, it is an order of magnitude larger.

NeoMails is not a feature improvement. It is a category. The inbox, reconceived as an attention and monetisation surface, is an asset class that has never been properly valued or systematically exploited. NeoMails are the instrument for doing so — at scale, with trust intact, and without the platform tax that every other channel demands.

Gold has long been seen as a safe haven because its price has kept pace with the rate of inflation for centuries, albeit punctuated by busts and booms. The booms tended to come in periods when real interest rates declined. As returns fell on money held in savings accounts or bonds, people tended to move their wealth into gold, which offers no yield but at least can rise in price.”

A B2C Product in B2B Clothes

There is a mindset trap that catches most teams when they first build NeoMails. It goes like this: NeoMails are sold to brands, brands are our customers, therefore we should optimise for what brands want. What brands want is engagement that drives commercial outcomes. Therefore, NeoMails should be designed to drive commercial outcomes.

This logic is internally consistent and entirely wrong.

NeoMails are sold to brands (a B2B motion), but they succeed only if customers experience them as a consumer product (a B2C reality). The brand is the distribution channel. The customer is the user. And you cannot design a consumer product by optimising for the distribution channel’s preferences. You have to design it for the user’s experience.

The test is brutally simple: would customers miss this email if it stopped? Would they notice its absence the way they notice when a daily game disappears, or a morning digest they liked goes dark? That is the standard NeoMails must meet.

This standard is higher than anything email marketing has previously attempted, because it requires the brand to temporarily step back from its commercial agenda and ask a different question: what does this person genuinely want to experience in their inbox today? Not what do we want them to buy, not what offer will move the needle, not what subject line will improve open rates — but what is worth 60 seconds of their genuine, voluntary attention?

The closest analogies are not marketing products. They are habit-forming consumer experiences: Duolingo, for its daily streak and micro-lesson format. Wordle, for its single daily puzzle that creates the right amount of scarcity. The best morning digests, for making information feel like a daily ritual rather than a duty. What these products share is the quality of being anticipated — the customer wants to engage before the product has asked them to.

Anticipation is the outcome NeoMails are designed to create. It is the opposite of the current state, in which most brand emails are tolerated at best and ignored at worst. Anticipation requires consistency (the email arrives at the same time, in the same format, with the same structural cues), quality (the Magnet is genuinely interesting, the content is genuinely relevant), and progress (the Mu balance grows, the streak extends, the story continues).

The Implications for Build Decisions

The B2C mindset has practical implications for every build decision. Magnet formats must be designed by people who think about consumer entertainment, not marketing copy. Mu mechanics must be designed by people who understand habit formation, not loyalty programme economics. The BrandBlock approval workflow must be fast enough that the brand can respond to real-world events and maintain relevance — not slow enough that it functions like a campaign approval process.

And the metrics that matter are consumer metrics, not campaign metrics. Not open rate — but repeat open rate. Not click rate — but interaction completion rate. Not list growth — but CRR improvement. Not impressions — but Mu earned per user over 90 days. These are the metrics of a product that customers have chosen to make part of their daily routine, not a campaign that was pushed at them once.

The brands that will adopt NeoMails fastest are the ones whose teams are willing to make this shift: from thinking of themselves as senders of messages to thinking of themselves as publishers of a daily consumer product. The inbox is the distribution surface. NeoMails are the content. The customer is the audience. Build for the audience, and the commercial outcomes will follow.

But fundamentally the same core product, solving the same core problem, the same core way. Salesforce in 2025 looked a lot like Salesforce in 2015. HubSpot in 2025 looked a lot like HubSpot in 2017. Zendesk, ServiceNow, Workday — same story. You could plan product roadmaps in 3-year increments and not be wildly wrong. That era is over. So, so, so over. And it ended so quickly.”

Tyler Cowen: “If AI produces a lot more stuff, income is generated from that and the economy keeps going, whether or not the resulting distribution pleases your sense of morality.  Along the way, prices adjust as need be.  If unemployment rises significantly, prices fall too, all the more.  I am not saying everyone ends up happy here, but you cannot have a) a flood of goods and services, b) billions accruing to the AI owners, without also c) prices are at a level where most people can afford to buy a whole bunch of things.  Otherwise, where do you think all the AI revenue is coming from?  The new output has to go somewhere, and sorry people it is simply not all trapped in currency hoards.”

The Email as Product — Header, Body, Footer

Most innovation in email has obsessed over the body. Better images. More personalisation. Dynamic content blocks. AMP interactivity. These are meaningful improvements, but they miss a larger truth: a NeoMail is not a message with a good body. It is an end-to-end product experience that treats every pixel — from the preview pane to the final line — as intentional design surface.

This requires thinking about three zones of the email that most marketers treat as afterthoughts.

The Header: From Line, Subject Line, and Mu Signal

The header is the first experience the customer has — and in many cases, it is the entire experience, because the email is seen in a preview pane without being opened. This means the from-line, subject line, and preheader are not merely labels. They are the product’s opening move.

The from-line must feel like a product the customer recognises and has chosen, not a campaign they are being subjected to. ‘YourBrand NeoMails’ is better than ‘YourBrand Marketing’. The distinction signals that this is a different kind of email — one with a different purpose from the promotional send that arrived yesterday.

The subject line carries the Magnet preview — the hint of today’s quiz or prediction or story — rather than a marketing headline. ‘Which country produces the most coffee? + earn 20 Mu today’ is a fundamentally different promise from ‘40% off this weekend only’. It is curiosity-led rather than urgency-led, and curiosity compounds over time in a way that urgency never can.

The Mu signal in the subject or preheader is a subtle but powerful cue: ‘+20 Mu available today’ functions the way a Duolingo streak notification functions — as a gentle, non-threatening prompt that today’s engagement is a step in a continuing story.

The Body: BrandBlock, Magnet, ActionAd in Sequence

The sequence matters as much as the content. BrandBlock first — speaking to an already-engaged customer. Magnet second — deepening the engagement. ActionAd third — offering a utility to a customer who is present and active. This is the only sequence that respects the customer’s attention hierarchy. Any other order inverts the value exchange and turns NeoMails back into a promotional email with extra components.

All interactions happen via AMP — inside the email, without navigating to a browser. This removes the click-through friction that causes most email engagement to evaporate at the transition point. When the Magnet is answered inside the email, the engagement is real. When the ActionAd action is completed inside the email, the conversion is real. Nothing is lost to the gap between intent and execution.

The Footer: Status, Ledger, and the Right to Leave

The footer of a NeoMail is not legal small print. It is a trust mechanism and a continuity signal. The status bar shows the customer where they are — ‘Day 14 streak’, current Mu balance — and makes the ongoing nature of the relationship visible. The Mu Ledger shows the history transparently: what was earned, when, and why. This accountability is not just reassuring; it is part of the product.

The unsubscribe option in a NeoMail footer is different from a standard unsubscribe: it allows the customer to exit the NeoMails programme specifically, without opting out of all brand communications. This is one of the most important design decisions in the entire system. NeoMails must be optional without being punitive. A customer who finds the Magnet format not to their taste should be able to step back from NeoMails without destroying the broader CRM relationship. The exit must be clean, simple, and without consequence — because a product that traps its users is not a product people trust.

David Friedman: “Within the firm coordination is by central control, executives figuring out what workers should do and workers doing it as instructed. If that form of coordination was always and inevitably inferior to coordination by market transactions the result would be an agoric economy, each individual buying inputs and selling outputs, coordinating their activities by market transactions. Why does that not happen? How is it possible for a firm coordinated from above by its owner-manager to compete with the market alternative? Coase’s answer was that while centralized coordination indeed has costs, so does market coordination.” [via Arnold Kling]

Something big may indeed be happening with AI itself. For now, it remains largely invisible in the macroeconomic data.”

ET on the National Monetisation Pipeline (NMP 2.0) : “At the heart of the NMP framework is a distinction that policymakers have repeatedly stressed that asset monetisation is not outright privatisation. The government retains ownership of the underlying assets. What is transferred is the right to operate, maintain and earn revenue from brownfield infrastructure for a fixed concession period, typically under transparent bidding frameworks such as toll-operate-transfer models, infrastructure investment trusts, long-term leases or public-private partnerships. The economic logic of NMP 2.0 is straightforward. India has invested heavily in creating physical infrastructure such as highways, transmission lines, ports, airports, pipelines and railway freight corridors. These are capital-intensive assets with long gestation periods. Once operational and revenue-generating, they can be leased to private operators who are often better placed to extract efficiency gains and bear operational risks. The upfront proceeds realised by the government can then be recycled into new greenfield projects, creating a virtuous investment cycle. In effect, the state converts illiquid public assets into liquid financial resources, without relinquishing ultimate ownership. This recycling of capital is the core principle of NMP 2.0.”

ActionAds — Monetisation That Earns Its Place

The most common objection to NeoMails, when the concept is pitched to CMOs, is about the ActionAd. Will the brand allow third-party content inside its email? Will it feel like a betrayal of trust — the brand commoditising the relationship it spent years building?

The objection is legitimate. And the answer is not ‘trust us’. The answer is architecture.

One ActionAd per NeoMail, maximum. This is the foundational constraint. It is not a preference or a guideline; it is a hard limit built into the platform. Everything else in the ActionAd model is built on top of this constraint, because without it, NeoMails become an ad vehicle — and an ad vehicle will not earn the daily open that makes the whole system work.

Traditional email advertising fails for predictable reasons. Newsletter sponsorships ask the reader to shift context from the publication’s voice to a partner’s voice. Banner ads inside emails signal ‘this is transactional, not relational’. List swaps expose customer data to third parties without meaningful consent. All of these formats extract attention rather than earn it, and all of them degrade the quality of the inbox experience over time.

ActionAds are designed around a single organising principle: monetisation must be action-first, not click-first. The goal is not to take the customer somewhere else. The goal is to enable something useful, right here, in one step.

The formats that work best in this model are those that feel less like advertisements and more like featured utilities. One tap to save your details for a service you might use. One tap to book a discovery call. One tap to get a personalised quote. One tap to register for an event. One tap to subscribe. The ActionAd is not asking for your attention in exchange for nothing. It is offering a shortcut to something you might genuinely want to do — and making it frictionless.

The reason this matters economically is that ActionAd effectiveness is measured in actions completed, not impressions delivered. This is a meaningfully better metric for partners, because it is a direct measure of intent rather than an estimate of attention. An email database with a high-engagement NeoMails programme — where customers are opening daily, interacting with Magnets, and actively present in their inbox — is a meaningfully more valuable surface than a high-volume, low-engagement blast programme. The partner is not buying reach. They are buying access to real, demonstrated attention.

The Constraints That Make It Work

Beyond the one-ActionAd-per-email cap, the remaining constraints are equally non-negotiable. Category exclusions prevent competitors from appearing. Every partner category is whitelisted by the brand before any ad runs. An automatic pause triggers if complaint rates exceed a threshold.

Each constraint addresses a specific failure mode. The cap prevents the email from feeling like an ad vehicle. The category exclusions protect competitive positioning. The whitelist process keeps the brand in control of its associations. The complaint-rate trigger ensures the system is responsive to customer signals.

The result is a monetisation layer that earns its place — not by forcing itself onto the customer, but by offering something genuinely useful at a moment when the customer is already present and already engaged.
