From 10+TB a day to nano segmentation: How Max Me delivered personalized marketing results in 3 months with Supermetrics

Max Me Corp Co., Ltd is the digital unit of PTG Energy Group, one of Thailand's largest energy companies. The team manages the MaxCard loyalty platform across PTG's wider ecosystem, known internally as MaxWorld. This spans PT petrol stations, MaxMart supermarkets, Punthai Coffee, Coffee World cafes, Subway restaurants, and Autobacs fast-fit service centers.

PTG Energy was collecting around 10+TB of customer data per day. The data was rich and granular, offering insights into customers’ daily lives — but it was sitting unused in the company’s data warehouse.

Max Me was set up to put this data to work. The unit’s two-person team was given three months to set up personalized, data-driven marketing campaigns and prove the ROI to the board.

So they turned to Supermetrics for help.

The challenge: a small team, a massive dataset, and a tight deadline

PTG Energy was generating 10+TB of data each day across multiple business units, point-of-sale (POS) systems, and digital channels. What it didn't have was a way to unify it and act on it.

Most standard marketing tools couldn't handle the volume or complexity of Max Me's data. More advanced platforms had the capability, but still required significant engineering work to set up at the scale and speed Max Me needed. Meanwhile, the team didn’t have the time or resources to build an in-house solution.

Max Me needed a different approach. It needed a tool that could handle the scale of PTG's data without requiring a full engineering setup, and without waiting months before it started delivering results.

The solution: why Max Me chose Supermetrics

Max Me shortlisted several vendors who claimed they could handle the data at scale. Before committing to any provider, Max Me ran every option through the same test: upload PTG's full dataset and see what happened.

One platform crashed on day one, while another took more than a week to process the upload. Supermetrics was the only one that handled the volume. The platform was designed for large-scale data without requiring a full engineering setup or long implementation program.

Supermetrics allowed Max Me to do three things:

• Bring data together across the ecosystem. PTG's customer data was spread across multiple POS systems alongside online channels and the Max Me app. Supermetrics brought these sources into a single system the marketing team could work with directly.
• Build audiences and campaigns with minimal effort of engineering support. The team could segment customers, design journeys, and launch campaigns through the platform's interface — without writing code or filing tickets with a data team.
• Run, test, and iterate quickly. Campaigns that would have taken weeks of engineering work to set up could be launched in a day, tested for a few days, and either kept running or dropped. That made experimentation cheap and fast.

For Max Me, the relationship with Supermetrics quickly went beyond a typical vendor engagement. Supermetrics proactively shared best practices, worked through problems alongside the team, and suggested new approaches tailored specifically to Max Me’s requirements. This ensured the solution was designed around genuine business needs.

The result: a 25% conversion rate and nano-segmentation at scale

When Max Me started, the team consisted of two people. Neither had a deep engineering background, and both were responsible for the data integration, campaign design, and day-to-day delivery alongside the rest of their work at PTG.

This was a small team operating under real pressure to quickly deliver results. And with Supermetrics’ help, they succeeded.

The first campaign was a card-to-app conversion. When a customer registered a physical MaxCard, the team gave them 15 days to download the Max Me app. If they didn't, Supermetrics triggered an SMS reminder with a reward on registration.

The campaign converted 25% of cardholders into app users — and it's still running as an always-on journey. This was the successful proof that Max Me presented to the board at the three-month deadline.

Since then, the team has scaled up their personalization efforts.

Max Me now runs nano-segmentation campaigns aimed at as few as 20,000 customers out of a base of 25 million, with segments built from real behavior across both online and offline touchpoints. A customer who regularly buys coffee with milk receives offers on new milk-based products, while someone who drinks Americano doesn't.

The entire ecosystem now uses these personalized campaigns. For example, PT petrol stations wanted to sell an additional 100,000 liters of fuel across three stations in 10 days.

Max Me used Supermetrics to target 20,000 customers who regularly used those stations with a double-points offer. As a result, the campaign successfully hit the target.

The real impact

Within three months, Max Me validated their personalized marketing model and proved ROI. They quickly moved from having raw data that wasn’t being used to generating meaningful customer engagement at scale.

That’s the real impact of Supermetrics — it gave a small, non-technical team the capabilities to create data-driven customer journeys at scale.

Looking ahead, Max Me is evolving beyond segmentation into AI-driven personalization. With Supermetrics in place, the team is now equipped to unlock far more sophisticated customer journeys and push personalized marketing even further.
