Klaviyo Post-Purchase Flow: How We Added 15% to Client MRR
We increased a client’s monthly recurring revenue by 15% with a single Klaviyo flow.
That number isn’t a projection. It’s the directly attributable revenue this one automation added to their bottom line, month after month. The brand was already doing well with customer acquisition. But like many eCommerce stores I see, they were leaving a fortune on the table after the first sale.
Their post-purchase experience was a single, default Shopify notification. It confirmed the order and then went silent. This case study breaks down the exact steps we took to turn that silence into their most profitable automated marketing channel.
Client’s initial post-purchase engagement challenges
The client is a fast-growing Australian apparel brand. They have a great product and a strong social media presence that drives a consistent flow of new customers. When they came to us, their focus was almost entirely on top-of-funnel.
Their paid ads were working. Their organic traffic was healthy. But their repeat purchase rate was under 15%, which for an apparel brand with a high-quality product, is a red flag.
When we looked at their email marketing, the problem was obvious. They had a basic welcome series and an abandoned cart flow. That was it. Once a customer made a purchase, they received the standard Shopify order confirmation. Then, nothing.
This created several expensive problems.
There was no strategy to build customer loyalty. The brand spent good money to acquire a customer, only to immediately treat them like a stranger. This meant they had to spend that money all over again to get the next sale.
They had zero upsell or cross-sell opportunities in place. A customer would buy a shirt, and the system would never think to show them the matching shorts a week later. They were completely reliant on the customer remembering to come back and browse on their own.
The result was a huge amount of unrealised revenue. Every new customer was a potential repeat buyer, a potential advocate. But without any meaningful communication after the sale, that potential was just evaporating.
Our strategic approach to the Klaviyo post-purchase flow
Fixing this started with a full audit. We never build a single email without understanding the data first. As part of our process, we dug into their Shopify and Klaviyo accounts to understand the customer journey. If you’re curious about the specific opportunities hiding in your own Klaviyo account, our free Klaviyo audit can help identify them.
We analysed purchase data, looking for patterns. What’s the average time between the first and second purchase? What products are most frequently bought together? Who are the most valuable customer cohorts?
From this discovery phase, we set clear, measurable goals for the new flow. We weren’t aiming for vague “engagement”. We targeted a 10-point lift in the 90-day repeat purchase rate and an increase in average order value for second-time buyers.
With goals defined, we mapped out the new post-purchase customer journey. We broke it down into key phases: 1. Confirmation & Reassurance (Day 0): The moment of purchase. 2. Anticipation & Education (Day 1-5): The shipping period. 3. Product Experience (Day 7-14): When the product has likely arrived. 4. Relationship Building (Day 21): Reinforcing the brand connection. 5. Encouraging the Next Purchase (Day 30-45): The strategic ask for a second sale.
Based on this map, we structured a five-email Klaviyo post-purchase flow. Each email had a distinct job. We carefully planned the timing between each send to align with the typical shipping and delivery window for their customers.
The goal wasn’t to just send more emails. It was to send the right message at the right time to make the customer feel valued and guide them toward their next purchase.
Content and segmentation for the post-purchase flow
A good flow structure is useless without the right content. Generic, one-size-fits-all emails don’t work. We focused on two key areas: providing genuine value and using smart segmentation.
Personalization and value-driven messaging
We used Klaviyo’s dynamic content capabilities to make each email feel personal. For example, instead of a generic “Thanks for your order”, the first email dynamically pulled in the exact product image the customer bought. You can find detailed guides on this in the official Klaviyo Help centre.
The real shift was moving from purely transactional to value-driven content.
If a customer bought a pair of their premium running shoes, an email sent a few days later would link to a blog post: “5 Stretches to Do Before Your Next Run”. It didn’t ask for a sale. It provided useful information related to their purchase, building trust and authority.
If they bought a technical jacket, we sent them a short guide on how to properly care for the fabric to make it last longer. This shows the brand cares about the customer’s investment, not just the initial transaction.
Calls-to-action were also rethought. Instead of just “Shop Now”, we used CTAs like “Get the Care Guide” or “Watch the Tutorial”. This encouraged engagement with the brand beyond just buying more products.
Strategic segmentation within the post-purchase flow
We built conditional splits into the flow to create different paths for different customers. This is one of the most powerful features in Klaviyo, and it’s where most brands can find immediate wins. We have a whole post on creating powerful Klaviyo segments if you want to go deeper.
The two most important segments we built were:
1. First-Time vs. Repeat Customers: A new customer needs to be welcomed and educated about the brand. A loyal, repeat customer already knows you. We created a split so that first-time buyers received an email about the brand’s story and mission. Repeat customers skipped that email and instead received a simple “Welcome back” message with a small, unadvertised bonus like free shipping on their next order.
2. Product Category Purchased: A customer who buys a t-shirt has different needs than one who buys a $400 jacket. We segmented the flow based on the product category. Someone who bought from the ‘Lifestyle’ collection would receive cross-sell recommendations for other lifestyle items. Someone who bought from the ‘Performance’ line would see recommendations for socks, shorts, and other workout gear.
This level of segmentation ensures every message is as relevant as possible, which directly translates to higher click-through rates and more sales.
Metrics and outcomes from our Klaviyo post-purchase flow
Theories and strategies are fine, but results are what matter. The numbers from this new flow were immediate and significant. We track all our results closely, and this was a clear winner.
Within 60 days of launching the new Klaviyo post-purchase flow, it became the client’s highest-performing automation.
Here’s a breakdown of the key metrics: * Attributed Revenue: The flow directly generated an average of over $35,000 in sales per month. This represented a 15% increase in the company’s total monthly recurring revenue. * Open & Click Rates: The average open rate across the five-email flow was 58%, with a 9% click-through rate. This was a huge improvement over the generic Shopify notifications and even beat their existing welcome series. * Repeat Purchase Rate: The 90-day repeat purchase rate for customers who went through the flow increased from under 15% to 27%. We nearly doubled the number of customers making a second purchase. * Average Order Value (AOV): By suggesting relevant products, the AOV for purchases made through the flow was 18% higher than the site-wide average. Customers were not just buying again; they were spending more when they did.
The most important outcome was the long-term impact on Customer Lifetime Value (CLTV). Our projections showed that a customer who completed the post-purchase flow had a 12-month predicted CLTV that was 30% higher than a customer acquired before the flow was implemented.
This wasn’t a temporary sales bump. It was a sustainable system for turning one-time buyers into loyal, high-value customers.
