The Inbox Was Never an Owned Channel: Is Your Brand Ready for What Comes Next?

By Erin Kelsh & Stephen Meyer, 03.26.2025


The Disruption Already Happening

Email has been called an “owned” channel for as long as most marketers can remember, but it was always a rental agreement—you supplied the content, and inbox providers controlled the terms. Those terms have changed without notice. 

Apple rewrites preview text with an AI-generated summary before a human sees it. Gmail’s Gemini extracts key points from messages so the recipient doesn’t have to click through. Bots fire tracking pixels so open rate looks healthy, but no real eyeballs see your message. Omeda’s analysis of 2 billion emails confirms what many suspected: 81% of newsletter clicks aren’t human.

This isn’t a measurement problem. It’s a control problem. The longer brands treat it as the former, the longer they’ll optimize a channel they don’t own instead of building one they do. The tricky part: most companies aren’t prepared to make that shift.

The Harder Conversation

The pressure most brands feel right now isn’t coming from inbox providers; it’s coming from the boardroom. 

Email’s ROI has been the anchor for every marketing budget conversation for a decade: $36 back for every $1 spent, predictable, defensible, safe. Senior leaders build budget confidence around those returns, and that didn’t change when the channel’s foundations shifted. So, the instinct under pressure is to optimize harder: test more subject lines, increase frequency, tighten re-engagement flows. That puts more pressure on a channel already under structural strain. 

What rarely gets funded is evolution because it doesn’t come with a guaranteed return. It’s easier to make a case for a 2% improvement in click-through rate than a pilot for a capability with no benchmark.

The reframe that unlocks the conversation isn’t “email is in trouble.” It’s “here’s how we protect the returns leadership expects, while also extending into channels we control.” 

The Opportunity Hidden Inside the Disruption

Inbox disruption can serve as a springboard to better owned experiences. 

Look toward your app. Your loyalty program. Your authenticated web experience. These are environments where you control the presentation, you own the measurement, and no third party decides which messages are worth someone's attention. The brands that focus on these platforms aren't abandoning email, they're bridging the gap with what we call the “brand messaging center”: the layer that deepens the customer relationship and elevates email’s role to the acquisition and re-engagement engine. 

What the Brand Messaging Center Looks Like Today—and Where It's Going

What’s Happening Today

Some companies are already seeing success with similar strategies.  

Starbucks has quietly built the closest thing to this model, with 35.5 million active rewards members who increasingly check the app—not their inbox—for updates from the brand. Millions of individualized offers generated weekly, surfaced alongside reward tracking and contextual promotions, all inside a single experience Starbucks controls entirely.

Amazon operates a similar pattern through its in-app Message Center. Sephora has AI-powered recommendations and community engagement embedded in its Beauty Insider experience. Nike has experimented with persistent in-app content streams that feel native rather than interruptive. 

What separates these brands isn’t just infrastructure—any enterprise can license a platform with in-app messaging capabilities. It’s the skilled practitioners making deliberate choices at every layer: which audiences to migrate, what content to keep consistent long-term versus change for push communications, how to orchestrate across channels without creating noise, and how to measure what’s actually working. The technology is accessible. The strategy behind it is the differentiator.

But what exists today is still largely a digital version of the same broadcast model: the brand decides what to say, packages it, and pushes it out through a different channel. The brand messaging center of the future isn't a better channel. It's a fundamentally different relationship. Most brands aren't there yet. But the trajectory is clear, and the building blocks are more accessible than you'd expect. 

 

Where It’s Going 

Imagine opening a brand's app and being greeted not by a static feed of promotions, but by something that genuinely knows you. Not your segment, you. What you bought last, what you browsed and didn't buy, what's running low based on your purchase cadence, what's new that maps to your actual preferences. Not because a marketer built a journey for your cohort six weeks ago, but because an AI layer is assembling your experience in real time, with inventory, loyalty status, location, behavior, and purchase history all converging the moment you open the app. 

This is what becomes possible when brands move from campaign-driven messaging to context-driven conversation. 

A customer sees a personalized offer and asks a question about it directly in the interface, not through a separate support channel. "Does this work with what I bought last month?" "Can I use my points on this?" An AI agent, connected to product data, loyalty systems, and order history, answers in real time, and if the customer wants to act, the transaction happens without leaving the conversation.  

New open protocol standards like MCP (Model Context Protocol) now allow large language models to securely connect to a brand's commerce, CRM, loyalty, and inventory systems simultaneously, meaning an AI agent inside your app can pull from every system that knows your customer and act on it in real time. The architecture exists. The strategic decision to build it into the customer experience is what's lagging. 

And the most significant unlock isn't personalization. It's anticipation. 

“You’ve logged roughly 400 miles on your running shoes based on connected fitness data; here's your next pair, in your size, with your loyalty discount applied.”  

“Your subscription product ships in three days, but you haven't reordered the add-on you usually pair with it. You're near a store with the item you saved to your wishlist last week, and it's the last one in stock.” 

These aren't marketing messages. They're services delivered through a messaging layer.  And that distinction is what transforms a messaging center from a channel customers tolerate into one they rely on. 

None of this happens by accident, and none of it runs on autopilot. Every one of these scenarios requires someone who understands both the data architecture underneath and the customer psychology on top—deciding what to surface, when, and how aggressively. AI powers the delivery. Human judgment powers the design.

Why This Matters Now

Every time inbox providers add more AI between your message and your customer, the case for building your own intelligent messaging layer gets stronger. A brand messaging center isn't a campaign tactic you can spin up when the numbers get bad enough. It requires connected data infrastructure, creative systems that can personalize at scale, and teams that know how to orchestrate across owned channels rather than manage them in silos. The brands that start now, even with a single use case, won't just be hedging against inbox erosion. They'll be building a direct line to their best customers that no algorithm can interrupt.

Disruption in the inbox isn't the end of the story. It's the beginning of a better one, but only for brands willing to build it.

The Merkle Perspective

We sit at the intersection of CRM strategy, messaging technology, and AI-driven experience design. We don't think in channels, we think in customer relationships, then work backward to the data, platforms, and touchpoints that serve them best. That's what Modern CRM means to us: a framework that starts with the customer, connects the full owned-channel ecosystem, and uses AI to make every interaction smarter over time.

We manage email programs for many brands, and we're helping those clients think about what comes next to complement email, not replace it. We also work on the loyalty platforms, customer data infrastructure, and AI decisioning layers that make a brand messaging center possible. Bringing those together into a coherent owned-channel strategy is our specialty. 

Critically, we bring creative strategy and content into the same conversation, because the most sophisticated personalization engine still falls flat if what it's serving isn't compelling. The brands that win this next phase will need both sides working in lockstep, and that's where we come in. Reach out to explore what it’ll take to build your brand messaging center.
