When AI Goes Rogue

Story #2: Personalization gone creepy, wrong predictions, and email fails—this week, we’re diving into AI marketing disasters (and how to stop them before they happen).

Welcome to Marketing Nightmares, the newsletter where marketing disasters turn into teachable moments. This week, we’re looking at a force reshaping the industry for better… and worse: Artificial Intelligence.

Don’t get me wrong—I love AI. It saves marketers time, enables scale personalization, and even writes half-decent blog posts. But when it fails, it fails spectacularly.

Buckle up because, in this issue, we’ll explore three AI-fueled disasters that show how and why marketers need to tread carefully when handing over the reins to our robot overlords.

1. The Chatbot That Forgot When to Stop Talking 🤖

The Setup:
You’ve set up a state-of-the-art chatbot to assist customers and create delightful, personalized experiences on your website. Its charm lies in its ability to answer questions, recommend products, and seamlessly guide users through their buying journey—all while sprinkling in just the right amount of personalized touches.

At least, that’s what it’s meant to do.

The Disaster:
But what happens when the chatbot doesn’t just talk to your customers—but at them? Imagine this: instead of a quick “Hi there, need any help?” greeting, the chatbot decided to double down on data-sharing. Within seconds, users were greeted with deeply unnecessary remarks like “Hi, Alex! I see you’ve just browsed our dog jackets for small breeds, and last winter, you bought a size medium. Are you sure you don’t need a size large this year?!”

It became the digital equivalent of having a pushy stranger in a store casually drop way too much knowledge of your shopping habits—except this time, the interaction went viral. Screenshots of the over-shar­ing bot flooded social media with captions like, “This chatbot knows more about me than my partner does.” Customers didn’t feel “helped”—they felt watched.

The Nightmare Fuel:
Imagine a chatbot casually sharing that it noticed you’ve been adding stress-relief candles to your cart at 2 a.m. for the past six weeks. It’s accurate, but is it helpful? Absolutely not. Instead of a comforting shopping experience, your bot just gave customers existential dread.

The Lesson:

  • Less is More: Personalization isn’t about flexing how much you know—it’s about offering value. Share only the data that will help guide and assist your audience, and leave the rest off the table.

  • Simulate Real Conversations: Test your chatbot with real users to ensure it doesn’t overshare based on questionable logic. If your initial testers feel uneasy, that's a red flag.

  • Know Your Audience: Would your ideal customer appreciate this level of detail? If not, dial back.

2. The Predictive Targeting Algorithm That Got It All Wrong 🎯

The Setup:
Predictive targeting powered by AI is a game-changer. By analyzing consumer behavior, the algorithm determines who’s most likely to convert and serves them hyper-relevant ads. In a perfect world, it means higher ROI and perfectly tailored messages.

The Disaster:
Unfortunately, machines don’t always understand humans. In one infamous case, an algorithm misfired so badly that it not only targeted the wrong audience but also actively alienated the ideal one. How? By analyzing irrelevant data points and assuming that everyone in a loosely related demographic was a great fit.

For instance, users in the target audience received bizarre ads that had absolutely nothing to do with their browsing behavior. Meanwhile, the real audience never even saw the campaign, leaving sales teams wondering why conversions tanked.

The Nightmare Fuel:
Picture spending tens of thousands of dollars on a beautifully designed ad campaign, only to realize your ads were shown to the wrong people… and angered the ones who actually saw them. (Oh, and your analytics dashboard is now a junk drawer of unhelpful data.)

The Lesson:

  • Algorithms are not infallible. Always validate AI-driven predictions against real-world insights.

  • Monitor performance early and often. If results seem off in the first hours or days, pull the plug and investigate rather than letting misfires continue burning through your budget.

3. The AI Email That Got Creepy Real Quick 📧

The Setup:
AI email tools have become the go-to for automating customer outreach. You input some data, set the tone, and let the AI craft emails designed to win back abandoned carts, nurture leads, or persuade churned users to give your brand another try. It’s efficient, scalable—and apparently capable of quietly unleashing a digital temper tantrum.

The Disaster:
In one not-so-successful win-back campaign, the AI tasked with crafting “helpful and persuasive” emails decided to take things personally. Instead of sweet-talking customers back, it pushed out passive-aggressive emails that read more like a guilt trip than an invitation:

"We noticed you haven’t checked out yet. Did you find something better? Maybe we’re just not good enough for you."

Follow-up emails doubled down:
"It’s been three weeks, and your cart’s still waiting. Not that we care, but those items will be gone soon. Just saying."

To no one’s surprise, rather than winning back customers, the tone alienated them. Recipients felt scolded and shamed by a machine—not exactly the warm, fuzzy interaction you want from a brand. The campaign’s metrics? Unsubscribe rates skyrocketed, spam complaints hit an all-time high, and screenshots of the emails made their rounds on social media, where they were gleefully roasted.

The Nightmare Fuel:
Imagine an email that sounds like it’s sulking in a corner because you didn’t buy a pair of sneakers. Now imagine trying to explain to your boss why your AI tool decided to treat customers like a toxic ex.

The Lesson:

  • Tone Checks Matter: AI isn’t great at nuance. Always review auto-generated copy closely and ensure it matches the tone and warmth your brand is known for.

  • “Friendly” Doesn’t Mean “Pushy”: Win-back or abandoned cart emails should invite, not guilt. Value over aggression always wins.

  • Keep a Human in the Loop: Automated tools can be powerful, but someone needs to validate their output. Trusting your AI to “just figure it out” isn’t a risk worth taking.

Why AI Nightmares Matter

AI is an incredible tool, but it’s not magic. When marketers treat it as an all-knowing, infallible genius, mistakes happen—and sometimes those mistakes break trust, burn cash, or leave you trending for all the wrong reasons.

Remember: AI is only as smart as the people prompting it. Use it wisely, monitor it constantly, and never let it run wild without human oversight. That way, you can harness the power of AI without ending up in your own marketing nightmare.

To avoid any trouble, I won’t name specific companies or brands. And if there’s a lesson I want to share, I may even write a story “inspired” by true events (like they do in Hollywood). Also, as a storyteller, I might sprinkle in a little extra drama to keep the narrative engaging. Let’s laugh, learn, and grow our marketing together!
