Online shopping still runs through a system that was never really built for shopping in the first place.
For years, email has quietly done far more than it was meant to do in e-commerce. It acts as a login, a receipt folder, a promotions channel, a password recovery tool, an identity marker, a loyalty touchpoint, and often the main line between a brand and a customer. It works well enough that most people rarely stop to question it. But when you look closely, a lot of the friction people feel while shopping online can be traced back to that one habit.
That is the part Rohan Mahadevan keeps pushing on.
As the founder of Node and a former PayPal executive, Mahadevan is not looking at email-based shopping as a small annoyance. He sees it as a structural problem. In his view, the inbox has become overloaded with receipts, offers, shipping updates, account prompts, subscriptions, and lookalike messages that all compete for attention. Instead of making commerce feel smoother, email often makes it feel fragmented, noisy, and harder to trust.
The bigger point is not that people hate getting promotional messages. It is that email has become the default infrastructure for shopping relationships, even though it was designed for personal communication. Mahadevan’s argument is that modern e-commerce has outgrown that setup.
Why email became the default for online shopping
Email became the standard because it was simple, universal, and already in everyone’s hands.
If a merchant needed a way to identify a shopper, send an order confirmation, deliver tracking details, or follow up after a purchase, email was the easiest option. No new system had to be invented. The customer already had an address, the merchant already had a way to send messages, and the whole process could be layered on top of existing checkout flows.
For a long time, that seemed good enough.
The problem is that e-commerce kept growing, while the role of email kept expanding far beyond its original purpose. What started as a communication tool slowly became the operating system for online shopping. That shift happened so gradually that most brands accepted it without asking whether it was still the best fit.
Mahadevan’s critique starts right there. Email may be universal, but universal is not the same thing as well-designed.
Rohan Mahadevan’s real issue with email-based shopping
When Mahadevan talks about what is wrong with shopping through email, he is talking about more than inbox clutter.
His issue is that personal email now does too many jobs at once. It is expected to act as a shopper ID, a message center, an authentication layer, a marketing opt-in, a customer record, and a long-term archive of every transaction. That might sound efficient on paper, but in practice it creates a messy experience for both shoppers and merchants.
For consumers, it means shopping activity gets mixed into personal life. Order confirmations land beside work messages. Return notices get buried under newsletters. Discount alerts compete with family emails. Fraud warnings, loyalty updates, shipping notifications, and one-time promo blasts all show up in the same place.
For brands, it means they rely on a channel that is crowded, inconsistent, and increasingly hard to use well. Even when a customer wants to hear from a business, the message has to fight its way through an inbox full of unrelated noise.
Mahadevan’s position is that this is not just inefficient. It is outdated.
Inbox clutter is not a side issue anymore
Most shoppers know the feeling.
You buy one thing from a store and suddenly your inbox becomes a chain of messages that never really stops. First comes the order confirmation. Then shipping. Then delivery. Then a discount code for your next purchase. Then a reminder that your cart is waiting. Then a sale announcement. Then a seasonal campaign. Then a loyalty nudge.
None of this is unusual. In fact, it has become normal.
That is exactly the problem.
Shopping-related email has become so routine that people are expected to manage it as part of daily life. Over time, important information gets harder to find because it is trapped inside the same stream as everything else. Past receipts are scattered. Brand messages pile up. Subscriptions become easy to forget. Returns and exchanges are harder to track than they should be.
Mahadevan sees this as a sign that the infrastructure is wrong. If shoppers need to dig through a personal inbox just to manage everyday commerce, then the system is not helping them nearly as much as it claims to.
Why trust breaks down in email-driven commerce
The trust issue may be even more important than the clutter issue.
Email is one of the main places where phishing and impersonation thrive. Consumers are constantly asked to judge whether a message really came from a retailer, a payment service, a shipping carrier, or a support team. Some fake emails are obvious. Others are not.
That makes email a weak foundation for modern commerce.
If shoppers are trained to expect receipts, offers, alerts, verification links, and urgent account messages in the same channel where scams also appear, then confusion becomes part of the user experience. Even legitimate brands lose trust because the environment around them feels unreliable.
Mahadevan’s view is that this is not simply a matter of teaching customers to be more careful. It is a design flaw. Commerce has been built on top of a channel that bad actors can easily imitate, and that makes every real message a little less trustworthy.
The result is a strange contradiction. E-commerce is supposed to make buying easier, but the communication layer around it often makes shoppers more cautious, more distracted, and less sure of what to click.
Email was never meant to be a commerce identity layer
Another reason Mahadevan pushes against email-based shopping is that email now functions like a default identity system.
Think about how often a shopper is asked for an email address. Sometimes it is needed for checkout. Sometimes for an account. Sometimes for a newsletter. Sometimes for a discount code. Sometimes for loyalty benefits. Sometimes it is just there because brands want a way to reconnect later.
That creates a strange reality where a personal email address becomes the ticket into almost every commercial interaction.
Mahadevan clearly believes that is too much exposure for something so personal. When the same address follows you across stores, categories, and devices, it turns into a permanent commerce identifier whether you wanted that or not. It also creates friction. People use guest checkout because they do not want another full relationship with every brand they buy from. But email keeps dragging them back into an account-style system anyway.
This is one of the reasons Node is framed around the idea of a separate commerce identity rather than just a cleaner inbox. The thinking behind it is simple: shoppers should not have to hand over their personal email every time they want to buy something.
The hidden cost of email for merchants
It is easy to hear this debate and assume it is only about consumer convenience. It is not.
Mahadevan’s criticism of email-based shopping also has a merchant side.
Brands want conversion at checkout, but they also want retention after the purchase. That creates a tension. The easier the checkout flow becomes, the less likely a shopper is to want a full account relationship. But the more a merchant depends on email after the purchase, the more they are forced to pull that shopper back into a crowded, low-trust environment.
This is why so many e-commerce businesses feel stuck between guest checkout and account creation.
Guest checkout reduces friction, which can help conversion. But guest buyers are often harder to bring back because the post-purchase relationship is weak. On the other hand, forcing sign-up adds friction and can hurt the first sale.
Mahadevan’s broader point is that email sits awkwardly in the middle of this problem. It is treated like the bridge between brands and guest shoppers, but it is a poor bridge. It is noisy, unreliable, and too dependent on a channel that was never designed to carry the full weight of modern customer engagement.
What Node is trying to replace
Node is built around the idea that commerce needs its own identity and messaging layer.
Instead of asking shoppers to keep using personal email, Node gives them what it calls a Commerce Token. The pitch is that it works where an email is normally requested, but it separates shopping activity from the shopper’s personal inbox. Receipts, offers, order updates, subscriptions, and other commerce messages are meant to live inside a dedicated commerce environment rather than inside personal email.
That matters because Mahadevan is not arguing for a small email cleanup tool. He is arguing for a different model.
In that model, shopping data stays on the user’s device, commerce messages are organized around actual brand relationships, and the shopper keeps more control over what gets seen, stored, and acted on. The idea is to reduce spam, limit phishing risk, remove some account friction, and make repeat purchases easier without forcing the old sign-up flow.
Whether that model becomes mainstream is still a bigger question. But the problem it is responding to is real, and that is why Mahadevan’s argument gets attention.
Why email-based shopping feels older than people realize
One reason this topic lands is that online shopping has changed a lot, but the underlying communication system has not changed much with it.
Consumers shop across phones, laptops, apps, mobile wallets, marketplaces, and social platforms. They expect speed. They expect convenience. They expect trusted experiences. But so much of the post-click infrastructure still depends on passwords, inboxes, and traditional account logic.
Mahadevan describes this gap as part of a larger shift in commerce. His thinking suggests that the future of online shopping will not be built around filling out forms, recovering passwords, and sorting through inbox clutter. It will be built around faster identity, more direct permission, better organization, and more consumer control.
That is why his criticism of email-based shopping feels bigger than one app or one startup. It points to a broader question: if consumers now carry powerful personal devices everywhere, why should online shopping still depend so heavily on old systems that create friction, spam, and trust issues?
What makes this argument worth paying attention to
Even if someone never uses Node, Mahadevan’s critique is hard to ignore because it reflects everyday shopping behavior.
People are tired of unnecessary account creation. They are tired of cluttered inboxes. They are tired of guessing whether a message is real. They are tired of using personal email as the entry point for every commercial interaction.
That does not mean email disappears tomorrow. It is too deeply embedded for that.
But it does mean the weaknesses of email-based shopping are becoming harder to defend. What once felt standard now feels patched together. The customer journey may start with convenience, but it often ends in confusion, overload, and weak long-term trust.
Rohan Mahadevan’s core message is that e-commerce has been asking too much from email for too long. And once you look at online shopping through that lens, it becomes much easier to see why the current system feels so dated.
