In early 2025, Marriott made what seemed like a routine corporate decision: swap Coca-Cola for Pepsi across its entire hotel portfolio. What followed was anything but routine. Loyalty members revolted. Social media erupted. Some guests threatened to defect to competing chains — all over a soda. It was a vivid, real-time reminder that brand loyalty isn't rational. It's deeply, stubbornly emotional.
For small and mid-size business owners, the Marriott backlash isn't just a headline to scroll past. It's a case study in what happens when a brand underestimates the relationships it's built — and a blueprint for what you should be doing differently. Because the same emotional dynamics that drove guests to rage-post about fountain drinks are at play every time a customer opens (or ignores) one of your emails. Your brand loyalty email marketing strategy is either strengthening those bonds or quietly letting them fray.
The good news? You don't need a global hotel empire to build the kind of loyalty that keeps customers coming back. You need a direct line to your audience, a commitment to showing up with value, and the right approach to the most personal marketing channel you own: email. Let's break down exactly how to make that happen.
Marriott Switched From Coke to Pepsi — And Customers Lost It
What Happened and Why It Matters
In early 2025, Marriott announced it was replacing Coca-Cola with Pepsi across its portfolio of hotels and resorts. The reaction was immediate — and fierce. Social media lit up with complaints, loyalty members threatened to switch hotel chains entirely, and the story dominated headlines for weeks.
Over a soda.
On the surface, it seems like an overreaction. Dig deeper, and it's a masterclass in what brand loyalty actually looks like in the real world. Customers weren't mourning a beverage. They were mourning the experience they'd built around it — the poolside Coke at the Ritz-Carlton, the familiar taste that signaled "vacation mode." Marriott disrupted a ritual, and rituals are sacred.
The Emotional Reaction Brands Underestimate
Here's what most businesses get wrong: they treat customer loyalty as transactional. Points, discounts, punch cards. But loyalty is emotional. Customers form identity-level attachments to the brands they choose, and those attachments run deep enough to spark outrage over a drink swap at a hotel they visit twice a year.

Research consistently shows that loyalty programs work best when they nurture genuine brand advocates — not just repeat buyers. And with customer acquisition costs running significantly higher than retention costs across industries, the ROI case for deepening existing relationships is overwhelming.
Now consider this: if a beverage switch can trigger that level of backlash, imagine the loyalty — or disloyalty — your own customers feel every day. The inbox is where those relationships are built or broken.
And that's exactly where SMBs have an edge worth exploring.
Brand Loyalty Is Emotional — And Email Is Your Most Personal Channel
The Marriott backlash wasn't about taste tests or price points. It was personal. Guests felt their brand had changed without asking them. That reaction tells you everything you need to know about where loyalty actually lives — not in logic, but in emotion and trust.
This is exactly why email deserves more of your attention than almost any other channel.

Loyalty programs work not because they offer points, but because they make customers feel recognized and valued, turning one-time buyers into devoted advocates. As a small or mid-size business, you already have something Marriott doesn't: the ability to know your customers by name and mean it. That personal touch is a real competitive edge.
Email and SMS: The Direct Line to Your Customer's Trust
Email marketing for small business isn't just a channel — it's a relationship. It's permission-based, personal, and direct. Done right, it should feel like a conversation with a brand you trust, not an algorithm yelling at you from a screen.
That authenticity is something big-box competitors can't easily replicate at scale.
And the strategic importance of email is only growing. As AI reshapes how consumers discover and interact with brands — including Google's integration of Gemini AI into Gmail — inbox data is becoming an increasingly valuable asset. SMBs investing in a strong email retention strategy now aren't just driving today's revenue — they're building a future-proof foundation.
The brands that own the inbox will own the relationship. Understanding why loyalty is emotional is the first step. But knowing where to invest your limited budget to protect and grow it? That's where the math gets compelling.
