Key takeaways
- As acquisition gets more expensive, the modern marketing stack is shifting from winning new customers to keeping the ones you have.
- The essential stack for retail and hospitality: a CRM, marketing automation (email/SMS), analytics, personalisation, and a loyalty platform that ties them together.
- Loyalty has moved from "nice-to-have" to a core retention tool, because it's the layer that tells the rest of your stack who's loyal and who's about to leave.
- The strongest setups don't run loyalty in isolation. They feed loyalty data into the tools teams already use, like Klaviyo, to power sharper segmentation and personalised campaigns.
Every marketing team has a stack of tools, and every year the tools that matter change. The clearest shift right now: with acquisition costs climbing and customer switching remaining high, retention has become a bigger priority, and the stack is reorganising around it.
For CRM and marketing teams in retail and hospitality, that raises a practical question: which tools actually earn a place in the stack, and which are just noise? This guide breaks down the essential modern marketing stack, and why a loyalty platform has quietly become one of its most important pieces.
Why the marketing stack is changing
For years, the stack was built for growth at all costs: pour budget into ads, widen the funnel, win new customers. That model is breaking. Paid acquisition is more expensive than it used to be, with customer acquisition costs rising by an average of 60% over five years, while privacy changes have made targeting harder and consumers are more willing to switch brands than ever.
The result is a shift in priority from acquisition to retention: keeping and growing the customers you already have. Retention is more cost-efficient. It is widely cited that acquiring a new customer costs several times more than retaining one, and it compounds: loyal customers spend more over time, refer others, and cost less to serve. So the modern stack is being rebuilt around one question. Not "how do we get more customers?" but "how do we keep and grow the ones we have?"
What belongs in the modern marketing stack
Here's the essential stack for a retail or hospitality marketing team, and what each tool is for.
Most teams already have the first three. The gap is usually the last two, personalisation and loyalty, and they're closely linked, because loyalty data is what makes personalisation genuinely personal.
Why loyalty is the tool most teams are missing
Loyalty has quietly moved from "nice-to-have" to a strategic lever. In Deloitte's Consumer Loyalty Program Survey, loyalty programs rank just behind price and product as a driver of brand loyalty, and consumers say they get more value from brands with a strong program.
But the real reason loyalty belongs in the stack isn't the program itself. It's the data. A loyalty platform is the only tool that measures how attached each customer actually is to your brand. That signal is what the rest of your stack is missing: your CRM knows what someone bought, your email tool knows if they opened, but neither knows whether they're a loyal advocate or a discount-chaser about to leave. Loyalty data fills that gap, and makes every other tool smarter.
How loyalty connects the rest of your stack
The best marketing stacks aren't a collection of disconnected tools. They're integrated, with data flowing between them. Loyalty is increasingly the connective tissue.
Take the most common setup in retail and hospitality: a loyalty platform feeding a marketing automation tool. Instead of segmenting on purchase history alone, you segment on how loyal each customer is, then trigger the right campaign for each group through your existing email and SMS. That's the difference between blasting everyone the same offer and targeting with intent.
This is exactly how TRIFFT works with a tool like Klaviyo: TRIFFT measures each customer's loyalty, segments them by behaviour, and recommends the campaign most likely to improve loyalty for each segment, which you then run straight from Klaviyo. The loyalty platform supplies the intelligence; your automation tool does the delivery.
How to choose the right loyalty tool for your stack
Not every loyalty tool earns its place. For retail and hospitality teams specifically, look for:
- It measures loyalty, not just points. The value is in knowing how loyal each customer is, not just tracking transactions.
- It works online and offline. Retail and hospitality live in-store, so the tool must connect POS and in-person behaviour, not just ecommerce.
- It integrates with your existing tools. It should feed your CRM and automation platform, not replace them or sit in a silo.
- A lean team can run it. You shouldn't need a dedicated ops hire or months of setup to get value.
The bottom line: build a stack that keeps customers, not just wins them
The modern marketing stack is a retention stack. The teams pulling ahead aren't the ones with the most tools. They're the ones whose tools work together, with loyalty data at the centre telling the rest of the stack who to keep, who to grow, and who's about to leave.
If your stack already has a CRM, email and SMS automation, and analytics, the missing piece is usually the one that measures loyalty and prevents churn. That's the gap a loyalty platform fills, and it's why loyalty has become a core part of the retention marketing stack rather than a bolt-on. Add it, connect it to the tools you already run, and every campaign gets sharper: you segment by real loyalty, catch at-risk customers before they churn, and grow customer lifetime value instead of training people to wait for discounts.
That's where a platform like TRIFFT fits in. It measures how loyal each customer is, segments them by behaviour, recommends the campaign most likely to improve loyalty for each group, and works across ecommerce, in-store, and hospitality.
