Let’s rewind the game a bit. In Part 1, we saw the loyalty world through the player’s eyes, your customer. From the first brand encounter to checkout and beyond, we explored what it really takes to earn loyalty in a crowded arena.
Part 2 went deeper: we met the trendsetters and archetypes behind the screen. Experience-Driven Boomers, App-Hopper Gen Zs, and all the hybrid shoppers in between. Basically, we chose our fighter.
Now? It’s time to monitor performance, unlock upgrades, and make sure your loyalty program isn’t just running but racing ahead.
Here’s the thing: too many brands stop at the character selection screen. They launch a program, throw in some rewards, maybe even create a cool app and then… nothing. No tracking. No adaptation. No insight. Just a lot of coins left uncollected.
That’s why this final chapter exists. Because the endgame isn’t building a loyalty program. It’s building one that evolves and wins.
So let’s skip ahead and start at the finish line. What does success actually look like? Customers who become advocates, who know your brand, love your brand, and bring others along for the ride.
And guess what? You don’t get there by guessing.
You get there with metrics. The kind Kaizen helps you track, analyze, and turn into game-changing actions. Ready? Let’s press start.
Why Measuring Matters: Loyalty Needs to be Tracked
You launched your loyalty program. Great start. You’re on the track, kart revved, power-ups in place. But here’s the truth: starting the race doesn’t mean you’re winning it.
Even Mario wouldn’t make it to Rainbow Road blindfolded.
Without measurement, you’re just driving in circles. Fast, maybe flashy, but with no idea where you're headed or how you're doing. And in the loyalty game, what you don’t track can absolutely slow you down.
Think of metrics as your lap time, your drift accuracy, your item usage rate. Every insight helps you tweak your approach. Speed up here, brake there, drift through the curve of shifting customer behavior.
Because loyalty isn’t a one-time boost. It’s a circuit. And every loop gives you data. That data? It's not just numbers. It's signals, telling you:
- Who’s falling behind?
- Which power-ups (offers) work best?
- Where are the loyalty speed bumps?
- When is the perfect moment to re-engage?
Loyalty Power-Ups: What to Track and Why
A 2025 study analyzing $1.2 billion in e-commerce spending from 1.7 million customers revealed that businesses focusing on high-spending customers experienced over three times faster growth than those emphasizing broad customer retention.
Behind every high-performing loyalty program is a set of well-tracked, well-understood metrics. These aren't just numbers; they’re signals that show where you’re gaining momentum, where you're lagging, and where a well-timed boost could change the game.
Let’s look at what you should track, and what is optional for you to track.
1) Mushroom for Engagement Frequency
Mushrooms give you a short, sharp speed burst—perfect for slipping past the pack or catching up after a mistake. It’s not permanent, but it’s powerful when timed right.
High engagement is your speed boost. Low engagement? Drop a Mushroom of your own: send a time-limited offer, a push reminder, or spark interest with fresh content.
2) Golden Mushroom for Multi-Channel Interaction
The Golden Mushroom is a rapid-fire booster—you can hit it again and again for an extended burst of speed. It’s not subtle. It’s relentless.
If customers only engage in one place, you’re not using your full boost. Build a streak—link your campaigns across channels so they hop from email to app to store without losing momentum.
3) Red Shell for Offer Redemption Rate
The Red Shell is smart—it locks on, tracks your rival, and knocks them off their game. You don’t have to aim. Just fire and let it do the work.
If redemption is low, your offers aren’t hitting. Don’t throw random items—target segments that care. Personalize and time them right, just like a Red Shell that never misses.
4) Star for Customer Retention / Churn Indicators
The Star is pure magic. Speed, invincibility, immunity… You blast through obstacles, untouched. It’s a game-changer… for a limited time.
Spot the danger early. A well-timed Star—like a loyalty surprise or reactivation campaign—can stop churn before it starts. Stay alert, stay glowing.
5) Mega Mushroom for Net Promoter Score (NPS)
Mega Mushrooms super-size you. You become a towering force—stomping over smaller karts, impossible to ignore. It’s pure dominance.
High NPS? You're huge in their eyes. Low NPS? You're forgettable. Use feedback to grow where it counts—improve experiences, not just campaigns.
6) Bullet Bill for Customer Lifetime Value (CLV)
You’re way behind—then bam! Bullet Bill launches you to the front. You don’t steer. You just fly past obstacles.
Know who your high-value customers are. Invest more in keeping them, and use lookalike models to find more of them. That’s your fast lane.
7) Thunderbolt for Churn Rate
The Thunderbolt doesn’t play fair. It shrinks everyone ahead of you and wipes out their momentum. It’s disruptive, painful, and sudden.
Churn is the storm that flattens your lead. Monitor it closely. React fast with win-back campaigns or feedback loops before they disappear for good.
8) Banana Skin for Program Participation Rate
Banana Skins are silent troublemakers. Drop one and anyone who’s not paying attention spins out. They’re defensive, but sneaky.
If your participation rate is low, your program is invisible. Make joining feel like winning. Reward sign-ups, promote it everywhere, and make benefits instantly obvious!
Give Meaning to the Loyalty Metrics
Every metric has something to say, if you know how to listen. Like late-game power-ups in Mario Kart, the most telling data often shows up when the stakes are highest.
You’re on the final lap, and suddenly you get a Bullet Bill or a Star. That’s the game’s way of saying: you’re either way behind or right where you need to be for a comeback.
Your loyalty program data is no different. Metrics is a way of connection between your customers and your business.
- A drop in repeat purchases may be whispering, “We're losing their attention.”
- A sudden burst of cross-channel activity? That’s your audience shouting, “This moment matters!”
- A flattening of referral numbers might be quietly asking, “What’s in it for me now?”
Each metric is a checkpoint in your customer journey. When read together, they form a storyline: momentum building, moments missed, loyalty earned or lost. It’s not about obsessing over numbers, it’s about seeing the race they’re describing.
Adjust, Personalise, Repeat: Loop of Customer Loyalty
You don’t win Mario Kart with one perfect move, you win by staying responsive. You drift, dodge, adapt. Loyalty is no different.
What works today might be invisible tomorrow. A promotion that once created a redemption spike now barely moves the needle. A content format that drove massive engagement may start to feel stale. That’s not failure, it’s the track changing.
Loyalty programs thrive when they evolve. Feedback becomes fuel. The loop is simple, but it never ends.
Track → Learn → Adjust → Repeat
If your customers zig, you don’t keep zagging you pivot, reframe, offer something new. Dynamic personalization, fueled by clear, current insights, is the only way to stay competitive when everyone’s trying to win the same lap.

The race ends but loyalty doesn’t. Just like a Mario Kart match resets for the next round, customer loyalty is cyclical. Every experience leads into the next.
Advocacy is the final lap and the first one of the next race. Customers who refer, review, and recommend aren’t crossing a finish line. They’re becoming part of your crew.
These players (the ones becoming advocates) help others find the track. They’ve memorized the turns, they know where the boosts are. With the right insight, you can spot them early and reward them accordingly.
And here’s the kicker: advocates create new players. Loyalty becomes self-sustaining.
