Email marketing consistently delivers the highest return on investment of any digital marketing channel. Research shows it returns an average of $36 for every $1 spent. But sending occasional promotional newsletters is not what drives those returns. The real revenue engine in email marketing is automated flows: sequences that trigger at exactly the right moment in a customer’s journey and deliver the right message without any ongoing manual effort.
This guide covers every essential Shopify email flow, how each one works, the specific timing and content that makes each effective, which platforms to use, and how to measure and improve performance over time.
What Are Shopify Email Flows?
Shopify email flows are automated sequences of emails triggered by specific customer actions or time-based conditions. Unlike broadcast emails that go to your entire list simultaneously, flows are triggered at the individual level and respond to what each customer is doing.
A customer adds something to their cart and leaves without buying. An abandoned cart flow triggers automatically. A new subscriber joins your list. A welcome series begins. A customer completes their first purchase. A post-purchase sequence fires. Each flow responds to a specific behavioral signal and delivers a relevant message at the optimal moment.
The power of flows is their precision and timing. An email sent one hour after cart abandonment outperforms the same email sent 24 hours later. A post-purchase email sent the day after delivery outperforms one sent a week later. Flows let you deliver messages at exactly the right moment, personalized to exactly what the customer just did, automatically.
Shopify Email vs. Klaviyo: Which Platform Should You Use?
Before covering individual flows, it is worth understanding your tool options since the platform you choose determines what you can build.
Shopify Email is the native email tool built into your Shopify admin. It is free for up to 10,000 emails per month and handles basic flows including abandoned cart, welcome series, and post-purchase sequences. It is excellent for stores that are just starting with email automation and want a simple, zero-cost solution.
Klaviyo is the leading dedicated email marketing platform for Shopify stores. It integrates deeply with Shopify, pulling purchase history, browsing behavior, product preferences, and segment data in real time. It supports advanced multi-step flows with complex conditional logic, behavioral triggers, A/B testing, predictive analytics, and detailed revenue attribution reporting. Most high-growth Shopify stores use Klaviyo once they reach the stage where they want to maximize email revenue.
Our Klaviyo Shopify Integration service sets up Klaviyo correctly from day one, connecting your store data accurately and building the foundational flows that start generating revenue immediately.
For the flows covered in this guide, most can be built in either Shopify Email or Klaviyo. Where Klaviyo offers significantly more capability, that is noted.
The 8 Essential Shopify Email Flows
Flow 1: Welcome Series
The welcome series is the first automated sequence every new subscriber enters. It sets the tone for your brand relationship, introduces who you are, and ideally converts a new subscriber into a first-time buyer.
Most stores treat the welcome email as a single thank-you message. That is a missed opportunity. A properly built welcome series does far more than acknowledge a new signup. It builds trust, communicates your brand’s value proposition, highlights your best products, and creates a compelling reason to make a first purchase.
Recommended structure:
Email 1 sends immediately after signup. It delivers the welcome offer if you offered one (a discount or free shipping incentive in exchange for the subscription), introduces your brand warmly, and sets expectations for what subscribers will receive. Keep it concise and focused on the value you provide.
Email 2 sends two to three days after signup. It showcases your bestselling products or most popular collections. Use real customer reviews or social proof to build confidence. The goal is to help the subscriber understand what makes your products worth buying.
Email 3 sends five to seven days after signup for subscribers who have not yet purchased. Share your brand story, your mission, or content that deepens the relationship such as a how-to guide, a behind-the-scenes look, or a compelling customer story. For subscribers who have already purchased, exit them from this flow to avoid redundancy.
Email 4 sends ten to fourteen days after signup for non-purchasers only. Create a soft sense of urgency around your welcome offer if it has an expiry, or introduce a new reason to buy such as a limited-time product or a collection they may not have seen.
A well-structured welcome series consistently delivers the highest revenue per recipient of any automated flow because it captures subscribers at their highest point of interest.
Flow 2: Abandoned Cart Recovery
Cart abandonment is one of the most significant and most recoverable sources of lost revenue for any Shopify store. The industry average cart abandonment rate sits around 70%, meaning roughly seven out of every ten customers who add products to their cart leave without buying.
An abandoned cart flow does not recover all of them. But it consistently recovers between 5% and 15% of abandoned carts, which for a store doing meaningful volume translates directly into thousands of dollars in additional monthly revenue from purchases that would otherwise be lost.
Recommended structure:
Email 1 sends one hour after abandonment. This is your highest-converting email in the sequence. Keep it simple: show the products left in the cart, include a clear return-to-cart button, and keep the copy warm and helpful rather than salesy. Many customers abandon because they got distracted rather than because they decided not to buy. This email catches them while the purchase intent is still high.
Email 2 sends 24 hours after abandonment for subscribers who have not returned. Address potential objections directly. Reinforce your shipping policy, return guarantee, and any trust signals relevant to your brand. Consider including a brief social proof element such as a customer review of the abandoned product.
Email 3 sends 72 hours after abandonment for subscribers who have still not purchased. If you are comfortable offering a discount, this is the appropriate place to introduce one. Keep it time-limited to create genuine urgency. If you prefer not to train customers to wait for discounts, replace the discount with a strong value reinforcement message instead.
Exit subscribers from the flow immediately when they complete a purchase to avoid sending cart reminder emails to customers who have already bought.
Flow 3: Browse Abandonment
Browse abandonment is a less commonly implemented flow that captures a revenue opportunity most stores leave untouched. When a customer browses specific product pages on your store but leaves without adding anything to their cart, a browse abandonment flow triggers an email referencing the products they viewed.
This flow requires Klaviyo or a similar platform with the ability to track on-site browsing behavior. Shopify Email does not support browse abandonment natively.
Recommended structure:
Email 1 sends four to six hours after a qualified browse session where the visitor viewed the same product or collection multiple times without purchasing. Reference the specific products they viewed, provide additional information that might address purchase hesitation, and include a clear path back to those products.
The tone should feel like a helpful follow-up rather than surveillance. Something like “We noticed you were checking this out, here is what other customers say about it” works well because it leads with value.
Browse abandonment flows typically generate lower revenue than cart abandonment flows because the intent signal is weaker. But they capture revenue that no other flow touches and are worth implementing once your foundational flows are in place.
Flow 4: Post-Purchase Series
The post-purchase series is the most direct driver of customer lifetime value in your entire email program. A customer who just bought from you is at their highest point of trust and engagement with your brand. The way you communicate in the days and weeks after their first purchase largely determines whether they become a one-time buyer or a loyal repeat customer.
Most stores send only a transactional order confirmation and shipping notification. That is necessary but not sufficient. A strategic post-purchase series goes further.
Recommended structure:
Email 1 sends immediately after purchase as an order confirmation. Include the order summary, estimated delivery date, and a warm thank-you that reinforces the customer’s decision. Avoid discounts at this stage since the customer just paid full price.
Email 2 sends when the order ships with tracking information. Add a brief note about what to expect when the product arrives and any relevant care or usage tips that add value.
Email 3 sends three to five days after estimated delivery. Ask how the customer is enjoying their purchase. Express genuine interest in their experience. Include a product review request with a direct link to leave feedback. Reviews gathered at this stage have the highest completion rate.
Email 4 sends two to three weeks after purchase. Introduce complementary products or collections that relate to what they bought. Frame it as a personal recommendation based on their purchase rather than a generic promotional email.
Email 5 sends four to six weeks after purchase for customers who have not repurchased. Offer a gentle incentive to return, reference their previous purchase, and make it easy to shop again.
Flow 5: Win-Back Series
Customers go quiet for many reasons. They may have forgotten about your brand, found a competitor, or simply lost interest in the category for a period. A win-back flow systematically attempts to reactivate lapsed customers before you stop communicating with them entirely.
Define your lapse threshold based on your typical purchase frequency. For a store where the average customer buys every 60 to 90 days, a customer who has not bought in 120 days is lapsed. For a store with quarterly purchase cycles, 180 days might be the appropriate threshold.
Recommended structure:
Email 1 sends at your lapse threshold. Acknowledge the time since their last purchase subtly and remind them of your brand’s value. Feature your newest products or most popular items to give them a fresh reason to engage.
Email 2 sends two weeks after Email 1 for non-purchasers. Introduce a win-back incentive: a discount, free shipping, or exclusive offer. Make it time-limited to create genuine urgency.
Email 3 sends two weeks after Email 2 for non-purchasers. This is your last-chance message before you sunset the subscriber. Be direct about the fact that you will stop sending if there is no engagement. Some customers will re-engage simply because they do not want to miss out.
For subscribers who do not engage with any of the three emails, suppress them from your active list. Continuing to email truly inactive subscribers damages your sender reputation and deliverability for your entire list.
Flow 6: VIP Customer Flow
Your highest-value customers deserve a distinct communication experience that reflects their status and deepens their loyalty. A VIP flow creates that experience automatically.
Define your VIP threshold based on data rather than intuition. Common criteria include customers who have made three or more purchases, customers whose total spending exceeds a defined threshold, or customers whose purchase frequency places them in the top percentile of your list.
Recommended structure:
Email 1 triggers when a customer crosses your VIP threshold. Acknowledge their loyalty explicitly, welcome them to a special tier, and communicate the specific benefits they now receive such as early access to new products, exclusive discounts, or priority support.
Ongoing VIP emails should provide genuine exclusivity: early access to launches before the general list, invitations to private sales, birthday or anniversary offers, and content that makes VIP members feel like insiders. The content should feel meaningfully different from what your standard list receives, otherwise the VIP designation feels hollow.
A well-executed VIP program directly increases customer lifetime value. Customers who feel genuinely valued and recognized purchase more frequently, spend more per order, and refer more friends. Our Smile.io Shopify Integration service connects your loyalty program data with your email flows so VIP triggers fire at exactly the right moment.
Flow 7: Product Review Request Flow
Customer reviews are one of the most powerful conversion tools available to any Shopify store. Shoppers who read reviews convert at significantly higher rates than those who do not. Reviews also provide SEO value through user-generated content on your product pages.
A review request flow automates the collection of reviews at the moment when customers are most likely to respond positively, which is shortly after they have received and had a chance to use their purchase.
Recommended structure:
Email 1 sends five to seven days after the estimated delivery date. Ask sincerely for their feedback, link directly to the review form for the specific product they purchased, and keep the email brief and easy to act on.
Email 2 sends seven days after Email 1 for customers who have not left a review. A gentle reminder mentioning that their feedback helps other customers make informed decisions works well without feeling pushy. Offering a small incentive such as loyalty points in exchange for a review can increase response rates significantly.
Time your review requests based on your product type. A clothing item can be reviewed within a week of delivery. A supplement or skincare product might need two to three weeks before the customer has experienced enough to review it meaningfully.
Flow 8: Back-in-Stock and Price Drop Flows
These flows capture purchase intent from customers who demonstrated interest in a product but could not buy at the time either because it was out of stock or outside their price comfort zone.
Back-in-stock flows trigger when inventory is replenished for a product a customer previously clicked on or added to their cart. Price drop flows trigger when you reduce the price on a product a customer browsed or wishlisted. Both flows reach customers at a moment of renewed purchase opportunity and consistently deliver strong conversion rates because the intent signal is very specific.
These flows require platform capabilities beyond basic Shopify Email. Klaviyo supports both through its back-in-stock trigger and price drop trigger functionality, which connect directly to your Shopify product inventory data.

Key Metrics to Track for Email Flows
Measuring the performance of your flows is essential for continuous improvement. Track these metrics for each flow separately:
Open rate measures the percentage of recipients who open your email. Industry averages for eCommerce sit around 20% to 30% for automated flows, with welcome and abandoned cart flows typically exceeding this. Low open rates indicate subject line or sender name issues.
Click rate measures the percentage of opens that result in a click. A strong click rate for eCommerce flows sits around 3% to 8%. Low click rates despite good open rates indicate issues with email content, layout, or CTA placement.
Conversion rate measures the percentage of recipients who complete a purchase after receiving the email. This is the most direct revenue metric and the one to optimize most actively.
Revenue per recipient divides the total revenue attributed to a flow by the total number of recipients. This metric lets you compare the efficiency of different flows and identify which deserve the most optimization attention.
Unsubscribe rate measures how many recipients opt out after receiving a specific email. A spike in unsubscribes from a particular email usually indicates the message is either poorly timed, irrelevant, or too aggressive.
Connect your Shopify store to Google Analytics 4 to track email-sourced revenue at the session and conversion level in addition to your email platform’s attribution reporting.

Conclusion
Shopify email flows are the most reliable and cost-effective revenue automation available to any eCommerce store. They work continuously, they personalize automatically, and they generate returns that compound as your subscriber list grows.
Start with the three foundational flows: welcome series, abandoned cart, and post-purchase series. These three alone deliver the majority of email flow revenue for most stores. Then layer in the remaining flows as your program matures.
The stores that build strong email programs early grow faster, retain customers better, and become less dependent on expensive paid advertising over time. Every day without your flows running is a day of passive revenue left uncaptured.
Frequently Asked Questions (FAQs)
1. What is a Shopify email flow? A Shopify email flow is an automated sequence of emails triggered by a specific customer action or time-based condition. Unlike broadcast emails sent to your entire list at once, flows send to individual customers based on what they do. Common triggers include signing up for your list, adding items to a cart without purchasing, completing a purchase, or becoming inactive for a defined period.
2. What is the most important email flow for a Shopify store? The abandoned cart flow and the welcome series are consistently the highest-revenue flows for most Shopify stores. The abandoned cart flow recovers revenue that would otherwise be completely lost. The welcome series converts new subscribers into first-time buyers while their interest in your brand is at its highest. Both should be the first flows you build.
3. Do I need Klaviyo to run email flows on Shopify? No. Shopify Email, Shopify’s native email tool, supports foundational flows including abandoned cart, welcome series, and post-purchase sequences and is free up to 10,000 emails per month. Klaviyo is needed for more advanced flows such as browse abandonment, back-in-stock, price drop flows, and complex behavioral segmentation. Most stores start with Shopify Email and graduate to Klaviyo as they scale.
4. How much revenue should email flows generate for my Shopify store? A well-built email flow program typically generates between 20% and 35% of total store revenue for established Shopify merchants. Abandoned cart flows alone typically recover 5% to 15% of otherwise lost carts. Welcome series flows convert 3% to 10% of new subscribers into first-time buyers within the first 14 days. Post-purchase flows increase second-purchase rates by 15% to 30% compared to stores with no post-purchase communication.
5. How long should my welcome series be? Most effective welcome series run between three and five emails over a 10 to 14 day period. The exact length depends on your product complexity and how much brand story you have to tell. B2C product stores with straightforward products typically perform well with three to four emails. Brands with a strong mission, community, or educational component can support five to six emails before subscribers start to disengage.
6. Should I include a discount in my abandoned cart emails? It depends on your brand positioning and margin structure. Discounts in abandoned cart flows do recover more carts in the short term, but they also train customers to abandon intentionally to wait for a discount. A common compromise is to reserve discounts for the third and final email in the sequence rather than offering them immediately, so you only discount customers who were genuinely undecided rather than those who would have bought regardless.
7. How do I know if my email flows are performing well? The key metrics to monitor are open rate, click rate, conversion rate, and revenue per recipient for each flow. Compare your flows against industry benchmarks: abandoned cart flows should achieve open rates above 40% and conversion rates above 5% for well-optimized sequences. Post-purchase flows should see strong open rates above 50% given the high relevance of the content. If a flow is underperforming, test different subject lines, adjust timing, or review whether the content addresses the specific concerns a customer in that stage of the journey would have.
