Zero Co, the Australian sustainable household brand, uses purchase history, website behaviour and email engagement to time refill reminders and tailor product recommendations. McKinsey research found 71% of consumers expect personalisation online and 76% are frustrated without it. Small businesses can apply the same principle using the purchase and engagement data they already collect.
When my daughter was born, everything shifted. I became hyper-aware of what was in our home, the chemicals, the waste, and I knew I wanted to create a cleaner, safer space for her to grow up in. It wasn’t just about today, it was about building habits that set a better example for her future. But if I’m being honest, I’m not the most patient person. I wanted to implement everything at one, even though I knew that was not realistic, and also, likely not sustainable.
That’s when I came across Zero Co. It checked all the boxes, cleaner products, no nasty chemicals, and a bold mission to eliminate single-use plastics, something that was next on my list to tackle. What drew me in even more was their focus on impact. It wasn’t just about what they were doing as a business; it was about how I, as a customer, could be part of that change too, and that’s something I look for in the brands I support.
So, who is Zero Co. Zero Co, the Australian-born sustainable household brand, is on a bold mission to reduce single-use plastic waste. With refillable, eco-friendly products and a closed-loop delivery system, they’ve built a business that beautifully aligns profitability with purpose. But what truly sets Zero Co apart isn’t just their clever branding or bold mission; it’s how they’ve mastered the use of data-driven strategies to drive growth, foster loyalty, and deliver measurable impact.
From my first order (hello, beautifully designed starter kit!) to refill reminders landing perfectly in my inbox, it’s clear that Zero Co seamlessly uses data to deliver on its promise while giving me plenty of reasons to stick with them. In todays world of online buying, customers demand personalisation, and Zero Co are doing just this.
The Challenge
When it comes to sustainability, trust is everything. Customers want to know that the brands they support are walking the talk. For Zero Co, the challenge appears twofold, grow their customer base and optimise operations while delivering measurable impact, without ever compromising their values.
And as a loyal customer, I can tell you they’ve nailed it. Every interaction feels intentional, from the thoughtful timing of their refill reminders to the smooth returns process. That level of trust doesn’t happen by accident, it’s built with a solid foundation of strategy and smarts.
How Zero Co Uses Data to Deliver Purpose and Performance
Here’s what I’ve noticed as a customer (and what I think they’re absolutely nailing):
1. Personalised customer experiences
What I’ve seen.
I get perfectly timed reminders based on my purchase history, so sticking to my sustainable habits feels effortless. Their emails feel thoughtful, with tailored product recommendations and updates that actually add value, not noise.
How they do this (I imagine):
Zero Co likely taps into customer purchase history, website behaviour, and email engagement to deliver these personalised experiences. You know when you get an email and find yourself asking “How did they know?!” consumer behaviour data allows us to anticipate in our marketing sales techniques, providing an enhanced experience for our customers. It’s how companies know what you need before you do, and it’s this type of knowledge and information that build meaningful connections.
Also, the data doesn’t lie. A study by McKinsey found that 71% of consumers demand personalisation in their online experiences, and 76% get frustrated when they don’t get it.
Why it works:
For me, it’s simple, I don’t have to stress (or think) about running out of cleaning products or keep track of when to order. For them, it eliminates the guesswork. This makes it easier for me to stay loyal, and for them to drive repeat purchases, a win for both sides.
2. Smart supply chain management
What I’ve seen:
Orders always arrive on time, and their refill pouch return process is seamless. Sustainability has been turned into a system that feels effortless for customers.
How they might do this:
By analysing sales patterns, inventory levels, and return rates, Zero Co is able to ensure they have the right products in the right place at the right time. Their closed-loop system is data-driven, reducing waste and minimising unnecessary transportation.
Why it works:
As a customer, I trust that my orders will arrive when I need them. And let’s be honest, sustainability has to be easy for us to stick with it long-term. Zero Co makes it effortless in my opinion, and I’m here for it.
3. Data-driven campaigns that resonate
What I’ve seen:
Their campaigns hit home. From sharing educational content about plastic waste to celebrating the collective impact we’ve made together (like the amount of plastic saved), every message feels authentic and inspiring.
How they might do this:
By measuring campaign performance, website traffic, click-through rates, customer acquisition costs, and other key metrics, Zero Co can identify what resonates most with their audience. They focus their efforts where they know they’ll have the biggest impact.
Why it works:
As a customer, I feel like I’m part of something bigger. It’s not just about buying products; it’s about being part of a community where I feel like my family and I are making a tangible difference. That sense of shared purpose keeps me engaged and loyal.
The results (from a customer’s perspective)
Here’s why Zero Co stands out:

- Purpose that feels real: Seeing the data. How much plastic we’ve collectively saved makes me feel like my choices matter.
