Here is a stat that should make you rethink your marketing budget: for every $1 spent on email marketing, the average return is $42. Compare that to Meta Ads at $4–6 return per dollar, and you start to see why the smartest Shopify brands build their email engine before they scale their ad spend.

Yet most stores treat email as an afterthought. They collect emails with a generic pop-up, send the occasional blast when there is a sale, and wonder why email only accounts for 5–8% of their revenue. Meanwhile, the top-performing Shopify stores drive 25–40% of total revenue through email — most of it on autopilot through automated flows.
If you are spending money on ads to drive traffic and you do not have these five Klaviyo flows running, you are paying to fill a leaky bucket. Fix the bucket first.
Why Automated Flows Beat Campaign Blasts Every Time
Before we get into the five flows, it is worth understanding why automated flows outperform manual campaign sends so dramatically. A campaign is a one-time email you send to your list — a sale announcement, a new product launch, a seasonal promotion. Campaigns are useful, but they rely entirely on you pressing send.
Flows, on the other hand, are behaviour-triggered sequences that run 24/7 without you touching them. Klaviyo’s own data shows that automated flows generate an average of $0.25–$0.45 revenue per recipient, compared to $0.18–$0.30 for campaigns. That might sound like a small gap, but when you multiply it across thousands of subscribers triggering flows every month, the difference adds up to tens of thousands in revenue.
The best part? Once you build these flows, they work while you sleep. A store doing $40K/month with properly built flows should be generating $10K–$16K in email revenue every month without sending a single manual campaign. That is the baseline we aim for with every eCommerce Circle member.
Flow 1: The Welcome Series (Your Hardest-Working Salesperson)
Your welcome flow is triggered when someone joins your email list. This is the moment of highest engagement — they just expressed interest in your brand. What you send in the next 7 days determines whether they become a customer or forget you exist. A well-built welcome sequence should convert 5–12% of new subscribers into first-time buyers. If yours is converting below 5%, there is significant room to improve.
Here is the structure that works:
Email 1 (Immediately): Deliver the promised incentive (discount code, free shipping, etc.), introduce your brand in one sentence, and showcase your best-selling product. Keep it short — under 150 words. The goal is to get them to click through to your store while the interest is fresh. Subject line benchmark: aim for 50%+ open rate on this email.
Email 2 (Day 1): Tell your brand story. Why does your brand exist? What problem are you solving? This builds emotional connection. Australian shoppers especially love supporting brands with a genuine story and local roots. Include a founder photo or behind-the-scenes image — it humanises your brand and increases trust.
Email 3 (Day 3): Social proof email. Feature 3–5 of your best customer reviews with photos. Let your customers sell for you. This email typically has the highest conversion rate in the sequence because it tackles the “can I trust this brand?” objection head-on.
Email 4 (Day 5): Showcase your best sellers or curated collection. “Our customers’ favourites” is a powerful subject line because it combines social proof with product discovery. Include 3–4 products with images, prices, and star ratings.
Email 5 (Day 7): Urgency close. Remind them their welcome offer is expiring. Create a genuine deadline. “Your 10% off expires in 24 hours” drives action when the earlier emails built the desire. This email should include a countdown timer — Klaviyo supports dynamic countdown timers natively.
Pro tip: Add an SMS message after Email 1 if you have SMS consent. Welcome flow SMS messages convert at 2–3x the rate of email-only. Klaviyo’s SMS integration makes this a simple toggle within the flow builder.
Flow 2: Abandoned Cart Recovery (The Revenue Rescue)
Around 70% of online shopping carts are abandoned. That is not a stat to be depressed about — it is an opportunity. Every abandoned cart is a person who was interested enough to add your product but got distracted, had second thoughts, or hit a friction point at checkout. A good abandoned cart flow recovers 5–15% of those lost sales. Klaviyo’s benchmarks show that abandoned cart flows generate an average of $3.65 revenue per recipient — that is 12–20x a standard campaign send.
Here is the timing that works:
Email 1 (1 hour after abandonment): Simple reminder. “You left something behind.” Include a photo of the product, the price, and a direct link back to their cart. No discount yet — many customers simply got distracted and just need the nudge. This first email typically recovers 40–50% of all recovered carts.
Email 2 (24 hours after): Address objections. Include a customer review of the specific product they abandoned (Klaviyo’s dynamic content blocks make this possible), highlight your returns policy, or mention free shipping if they qualify. The goal is to remove the hesitation that caused the abandonment.
Email 3 (72 hours after): Final nudge with an incentive. “Still thinking about it? Here is 5% off to help you decide.” Small discounts (5–10%) are more effective than large ones because they create a sense of exclusivity without devaluing your product. Include a clear expiry on the discount — 48 hours works well.
Pro tip: Add an SMS message 4 hours after abandonment if you have SMS consent. The combination of email + SMS recovers 30–50% more carts than email alone. For stores doing $50K+/month, that can mean an extra $3,000–$5,000 in recovered revenue monthly. For more on getting your checkout conversion right, read our guide to Shopify checkout optimisation.
Flow 3: Browse Abandonment (Catch the Window Shoppers)
Browse abandonment emails target people who viewed a product page but did not add to cart. These visitors showed intent — they clicked through to a specific product — but something stopped them from taking the next step. This flow captures revenue that most Shopify stores completely ignore.
Email 1 (2 hours after browsing): “Still interested in [product name]?” Include the product image, a short benefit statement, and a link back to the page. Keep it simple — one product, one CTA.
Email 2 (24 hours after): Show related products or the collection they were browsing. Sometimes the first product was not quite right but a similar option will click. Use Klaviyo’s product recommendation engine to dynamically populate this email based on their browsing behaviour.
Browse abandonment emails typically convert at 2–5% — lower than cart abandonment, but because the volume is much higher (more people browse than add to cart), the total revenue impact is significant. Most Shopify stores doing $30K+ months see $1,500–$3,000/month from this flow alone. That is pure found revenue from people who would have otherwise forgotten about you.
Flow 4: Post-Purchase (Turn Buyers Into Repeat Customers)
The sale is not the end of the journey — it is the beginning of the most profitable relationship you can build. Repeat customers spend 67% more per order than first-time buyers and cost almost nothing to acquire. Your post-purchase flow is how you nurture that relationship and drive the critical second purchase.
Email 1 (Immediately after purchase): Order confirmation with a personal thank you. Not the generic Shopify notification — a branded email from Klaviyo that makes them feel good about their purchase. Include a message from the founder and set expectations for delivery.
Email 2 (3 days after delivery): “How are you enjoying [product]?” Include tips for getting the best results from their purchase. This reduces returns (customers who feel confident about their product are 40% less likely to return it) and builds satisfaction.
Email 3 (7–10 days after delivery): Ask for a review. Make it easy — a direct link to leave a review with a one-click star rating using tools like Judge.me or Okendo. Offer 10% off their next order for a photo review. Photo reviews convert browsers at 2x the rate of text-only reviews.
Email 4 (21 days after delivery): Cross-sell or replenishment reminder. “Based on what you ordered, you might love these…” or “Time to restock? Your [product] usually lasts about 30 days.” This email should use Klaviyo’s predictive analytics to recommend the products most likely to resonate based on their purchase history.

Flow 5: Win-Back (Re-engage Customers Before You Lose Them)
A customer who has not purchased in 60–90 days is at risk of churning. Your win-back flow is the last line of defence before they become a lost customer you have to re-acquire from scratch — which costs 5–7x more than retaining them. A well-built win-back sequence recovers 3–8% of at-risk customers.
Email 1 (60 days since last purchase): “We miss you” with a personalised product recommendation based on their purchase history. No discount — just a reminder that you exist and a reason to come back. Use dynamic content to show products related to what they previously bought.
Email 2 (75 days): Highlight what is new. New products, new reviews, new content. Give them a reason to come back beyond a discount. If you have launched any new collections since their last purchase, feature them prominently.
Email 3 (90 days): The “last chance” email with a meaningful incentive. “Here is 15% off because we would hate to see you go.” This is the appropriate time for a bigger discount — you are competing against the cost of re-acquiring them through paid channels, which typically runs $15–$40 per customer. A 15% discount is almost always cheaper than re-acquisition.

Setting Up Your Flows in Klaviyo: The Technical Basics
If you are new to Klaviyo, here is the quick-start path. First, ensure your Shopify-Klaviyo integration is active and syncing customer data, order data, and browsing behaviour. Go to Klaviyo → Integrations → Shopify to confirm.
To create each flow, go to Flows → Create Flow. Klaviyo has pre-built templates for all five of these flows — start with the template and customise the copy, timing, and design to match your brand. The templates give you a solid starting structure; your job is to make the content specific to your products and audience.
Key settings to get right: set your smart sending window to prevent over-emailing (we recommend 16 hours minimum between flow emails). Enable quiet hours so emails do not send between 10pm and 7am in your customer’s timezone. And always add a flow filter to exclude customers who have already purchased since entering the flow — you do not want to send a cart abandonment email to someone who already completed their order.
If you are not on Klaviyo yet, it is the platform we recommend for every Shopify store doing $20K+/month. Omnisend is a solid alternative for stores on a tighter budget, and Mailchimp has improved its ecommerce features recently, but Klaviyo’s Shopify integration and flow builder remain the gold standard.

The Compound Effect: How These Flows Work as a System
Each flow works on its own, but the magic happens when all five are running together. Your welcome flow converts new subscribers. Your cart and browse abandonment flows capture lost revenue. Your post-purchase flow builds loyalty and generates reviews. Your win-back flow prevents churn.
Together, they create a self-reinforcing system that drives 25–40% of your total revenue on autopilot. For a store doing $40K/month, that is $10–$16K in email revenue every month without sending a single campaign. For a store doing $100K/month, it is $25K–$40K. That is the power of automated flows — and why we insist every eCommerce Circle member gets these built before they scale their ad spend.
The typical implementation timeline is 2–3 weeks to build all five flows, with most stores seeing measurable revenue impact within the first 7 days of going live. Start with the welcome series and abandoned cart flow (they drive the most immediate revenue), then layer in browse abandonment, post-purchase, and win-back over the following two weeks.
