Email & SMS Retention Strategy for Australian Ecommerce Brands
Australia’s ecommerce retention landscape has its own rules. And if you’re applying a generic global playbook here without adapting it for local consumer behaviour, platform dynamics, and market realities, you’re leaving significant revenue on the table. After auditing dozens of Australian ecommerce accounts across fashion, swimwear, and lifestyle categories, the same gaps appear almost universally. The brands that struggle with retention aren’t failing because their product is wrong or their acquisition is broken, they’re failing because the relationship they build after the first purchase is almost nonexistent. This piece covers what we see, what we recommend, and what actually works for Australian DTC brands looking to build a sustainable email and SMS retention strategy.
The Post-Purchase Journey: Your Biggest Missed Opportunity
When I audit accounts, I consistently see the same foundational flows in place: abandoned cart, abandoned checkout, browse abandonment, and welcome. That’s a reasonable starting point. But the post-purchase journey and winback flow is either missing entirely or treated as an afterthought.
This isn’t a minor gap. It’s where retention is won or lost.
First-time buyers who receive personalised post-purchase communications show 45% higher second-purchase rates than those who receive no post-purchase outreach. Despite this, the majority of Australian brands go quiet the moment an order is confirmed. A transactional dispatch email goes out, and then nothing happens until the next campaign.
The post-purchase window is your most valuable real estate. From the moment a customer places their order through to receiving and using the product, they are at peak engagement. You are top of mind. That is the window to build a genuine relationship, and most brands aren’t using it.
What should be happening during that time? Personalised, considered content. Whether that’s a note from the founder, educational content related to the product just purchased, or simply acknowledging the customer as a new member of the brand’s community, every touchpoint in this sequence matters. Brands that get this right, and keep optimising it, see the impact reflected directly in their returning customer rates.
Email Retention: Personalisation Is the Differentiator
Australia sends over 8 billion emails per day, placing it in the top ten countries globally for email volume. Standing out requires more than a good subject line. For returning customers especially, generic broadcast content is a missed opportunity and a fast track to being tuned out.
Repeat customers make up only 21% of customers, yet they generate 44% of revenue and 46% of orders. That statistic alone should change how you think about your campaign strategy. Your returning customer segments are not just your most valuable audience, they are your most responsive one. Messaging that reflects where a customer is in their journey, such as “Add to your collection” or “Your next piece”, consistently outperforms generic sends because it speaks to someone who already knows and trusts the brand.
As an Australian consumer myself, I purchase from many local brands. The ones that influence my buying behaviour are the ones that treat me as an individual – they know where I am in my journey and they show up accordingly. That’s not luck. That’s an intentional strategy built on good segmentation and thoughtful content planning.
One of our clients, a leading Australian fashion brand, is a strong example of this in practice. After implementing more segmented and personalised email strategies, improving campaign cadence and increasing the relevance of communications they saw a 90% increase in email sessions period-on-period and a 123% increase year-on-year, with email’s share of total sessions growing from 2.8% to 4.4%. Over the same four-month period, Klaviyo-attributed revenue increased 16.18% period-on-period and 194% year-on-year.
The results from refining segmentation further were equally compelling. Over one month, the brand reduced campaign send volume by 32% while achieving a 30.8% month-on-month increase in placed orders and stronger engagement across key metrics. Sending smarter, not more frequently, is a principle we apply across every account we manage.
SMS Retention in Australia: A Higher Bar, a Better List
Australians are receptive to SMS marketing but they operate differently from consumers in the US or UK, and this distinction matters for your retention strategy.
Australians have a 97% read rate within 15 minutes of receiving a text message, which makes SMS one of the most powerful channels available to ecommerce brands. In Australia, consumers who sign up for SMS campaigns are 82% more likely to make a purchase, this figure reflects both the quality of the channel and the intent of the subscriber.
But there is a catch. Tolerance for irrelevance and poor timing is low here. The opt-in bar in Australia is higher than in many comparable markets, meaning your SMS list quality tends to be strong, but that trust must be earned and protected consistently. One poorly timed, off-context message can erode what took months to build.
SMS in an Australian email and SMS retention strategy should be used with discipline. It performs best when it’s timely, contextually relevant, and feels like a natural extension of the customer relationship. Think delivery updates, back-in-stock alerts for products a customer has shown interest in, exclusive early access for repeat buyers. These are the moments where SMS adds genuine value rather than noise.
Segmentation: The Engine Behind All of It
None of the above is possible without a solid segmentation strategy. First-time customers, one-time buyers, repeat purchasers, high-AOV customers – these audiences require entirely different conversations, and treating them as one standard list is one of the most common and costly mistakes we see in Australian ecommerce accounts.
The average DTC repeat purchase rate sits at 25–30%, with top-performing brands reaching 40% and above. For fashion and apparel specifically, repeat rates typically sit closer to 20–26% which means the majority of customers are still one-time buyers. That is where the biggest opportunity lies, particularly in the Australian market right now: converting those one-time buyers into second, third, and subsequent purchases through smarter segmentation and more relevant messaging.
Returning customer segments will consistently be your top-performing campaigns. They respond better, convert higher, and require less incentive. They also don’t need a formal loyalty program to feel rewarded – exclusive content, early access, and messaging that acknowledges their history with the brand goes a long way toward building the kind of loyalty that drives long-term LTV.
The goal is to use segmentation and personalisation across both campaigns and flows to move customers through the order count spectrum, from one-time buyer to second purchase, second to third, and so on, until they become genuine brand loyalists.
Integrating Email and SMS: When Both Channels Work Together
The most effective Australian ecommerce retention strategies use email and SMS in a coordinated, complementary way, rather than treating them as separate channels.
Email is the workhorse: longer-form, more content-rich, ideal for storytelling, product education, and nurturing the brand relationship over time. SMS is the interrupt: high-urgency, highly personal, best used sparingly and with precision. When these two channels are sequenced thoughtfully – for example, an email introducing a new collection followed by an SMS nudge for customers who opened but didn’t purchase – the combined performance consistently outperforms either channel in isolation.
The key is making sure the two channels don’t feel disconnected. Customers interact with a brand, not a channel. If your email says one thing and your SMS says something contradictory, or if a customer receives both within minutes of each other without clear coordination, the experience breaks down. Flow architecture and campaign scheduling need to account for cross-channel timing and suppress accordingly.
Measurement: How We Track Retention Performance at Thoughtful
Building a strong email and SMS retention strategy for Australian ecommerce retention is only half the work. Knowing whether it’s performing (and why) is what drives continuous improvement.
At The Thoughtful Agency, the metrics we prioritise for retention are:
Repeat Purchase Rate (RPR): The percentage of customers who return to purchase more than once within a defined window, typically 12 months. This is the clearest indicator of whether a retention strategy is working. For fashion and swimwear brands, we use 20–26% as a baseline and aim well above it.
Customer Lifetime Value (CLV): We track both Historic CLV and Historic Number of Orders using Klaviyo’s data platform to understand how much a customer is worth over their full relationship with the brand. This gives us a realistic picture of what acquisition spend is actually justified, and where to focus retention investment.
LTV Cohort Analysis: One of our most effective frameworks is identifying a brand’s top 10% of customers by Historic CLV and Historic Number of Orders. By reviewing that cohort’s behaviour (what they buy, how often, what content they engage with, how they first converted) we build a profile of what a “best customer” looks like for that specific brand. That intelligence then shapes segmentation, lifecycle automations, and messaging designed to lift LTV across the wider base. This analysis has become one of our most valuable strategic entry points for brands looking to maximise their CRM investment.
Together, these metrics give us a complete picture of retention health, and ensure the strategies we build are grounded in data rather than assumption.
Flows and campaigns working together, built around real customer behaviour, coordinated across email and SMS, and continuously refined through measurement – that’s what a genuine email and SMS retention strategy looks like in practice. And for Australian brands competing in a crowded market, getting this right isn’t optional. It’s the foundation of sustainable growth.
