10 Essential Klaviyo Flows Every eCommerce Store Needs
Every store owner dreams of a salesperson who never sleeps, never forgets a customer, and always knows the perfect moment to speak up. Klaviyo flows fill that role perfectly. These automated sequences react to shopper behavior, such as signing up, abandoning a cart, or buying a product, and they deliver the right message at exactly the right time.
Brands that build the right set of Klaviyo flows earn revenue around the clock without sending every email by hand. This guide covers the ten flows that matter most, explains why each one works, and shows how they combine into a strong ecommerce email automation system.
Why Klaviyo Flows Deserve a Place in Your Marketing Stack
Campaigns grab attention for a single day, while flows keep working long after the send button disappears. That difference explains why seasoned eCommerce marketers treat flows as an important element in their email marketing program.
Klaviyo's benchmark reports consistently show that flows generate a disproportionate share of email revenue relative to their share of total sends.
Relevance drives that result. A flow fires because a shopper did something specific, so the message matches the shopper's current intent instead of a guess.
Flows also support customer retention, which matters because acquiring a new buyer typically costs several times as much as retaining an existing one. The ten flows below fall into three groups: converting visitors, maximizing each order, and bringing customers back.
Perfect Your Email Marketing Campaigns with Klaviyo
Flows That Turn Browsers Into Buyers
The first group focuses on when a shopper hovers near the checkout button without pressing it. Each flow below meets visitors at a different stage of interest and gives them a reason to act.
Welcome series
A new subscriber has just signaled genuine interest, so the welcome series captures that enthusiasm at its peak. Welcome emails earn much higher open rates than regular campaigns because subscribers expect them.
A strong sequence runs three to four emails over about a week, covering the brand story, bestsellers, customer reviews, and a modest first-order incentive.
Shoppers who receive this introduction understand the brand's value before a competitor reaches their inboxes, which lifts first-purchase conversion rates.
Abandoned cart flow
According to the Baymard Institute, 7 in 10 online shopping carts are abandoned. This number makes abandoned cart emails more valuable.
An effective version sends a gentle reminder within an hour, adds product reviews or shipping reassurance after a day, and closes with a small incentive on day three.
These messages reach shoppers who chose their products, so they recover sales that would otherwise vanish. Many stores find that this flow produces the highest revenue per recipient.
Browse abandonment flow
A lot of visitors never reach the cart, yet many reveal clear interest by viewing a product page. The browse abandonment flow catches those visitors with a lighter touch than a cart reminder.
The email features the exact item they viewed alongside two or three similar picks, which feels helpful rather than pushy. Browsing traffic far outweighs cart traffic, so even a modest click rate adds a meaningful number of extra orders.
Back-in-stock flow
Few signals reveal buying intent as clearly as a shopper asking to be notified when an item returns. The back-in-stock flow responds to requests the moment inventory refills.
Klaviyo integrates with the product catalog, so the alert is sent automatically with a direct link to the item. Subscribers asked for this message, so engagement stays high, and scarcity wording like "only a few left" encourages quick decisions. Sold-out products, therefore, become future revenue rather than lost traffic.
Flows That Make Every Order Count
A purchase marks the beginning of the relationship rather than the end. The next three flows use the days after checkout to deepen trust and grow the value of each customer.
Post-purchase thank-you flow
The moment after checkout carries more emotion than any other point in the journey. A thank-you flow uses that warmth to confirm the order, share the brand's values, and explain how to get the most from the product.
A personal note from the founder makes the buyer feel like a person rather than an order number. These emails also reduce "where is my order" support tickets, which saves the team time.
Customers who feel appreciated early tend to return more often, so this flow quietly builds customer retention.
Cross-sell flow
Buyers who purchase one product often need a companion item. A cross-sell flow reads the order and recommends complementary products a few days after delivery.
A shopper who bought a coffee grinder, for instance, receives suggestions for filters and fresh beans.
Timing matters here because the customer trusts the brand and has what they need. Cross-sell emails raise AOV without spending money.
Review request flow
Social proof drives conversions, and satisfied customers supply it better than marketing copy. The review request flow asks for feedback about two weeks after delivery, when customers have genuinely used the product.
Short emails with a one-click star rating collect more responses than long forms. Each new review strengthens the product page and improves conversion for future visitors.
Reviews also expose product problems early, giving the team honest data for improvement.
Flows That Bring Customers Back
Repeat buyers spend more and cost less to reach than first-time buyers. The final group of Klaviyo flows protects that valuable audience and keeps the relationship active.
Replenishment flow
Consumable products such as skincare, pet food, and supplements run out on a predictable schedule. A replenishment flow calculates the timeline and nudges the customer just before supplies run out.
Klaviyo's predictive analytics estimates each shopper's next order date, removing the guesswork. An email with a one-click reorder link eliminates friction at the exact moment. Customers who reorder on schedule rarely drift toward competitors.
Winback flow
Every customer list contains people who bought once and then went quiet. The winback flow reaches out after a period of inactivity, typically 60 to 120 days, depending on the product's buying cycle.
A friendly "we miss you" message paired with new arrivals or a tailored offer often revives interest. Re-engaging a past buyer costs far less than finding a new one.
When a contact ignores the entire sequence, the brand can suppress that address to protect deliverability and sender reputation.
VIP flow
A small group of top customers usually generates a large share of revenue, a pattern many marketers associate with the 80/20 rule. The VIP flow triggers when a customer crosses a spending or order-count threshold.
The email offers early access to new launches, exclusive perks, or a sincere thank-you. Recognition strengthens loyalty and turns big spenders into brand advocates who recommend the store to friends.
Final Thoughts
Klaviyo flows work like a team of tireless assistants, each handling one important moment in the customer journey. The welcome series establishes the relationship, abandoned cart emails recover lost sales, and post-purchase flows increase order value.
Replenishment, winback, and VIP sequences keep loyal customers close. A store does not need all ten on day one. Starting with the welcome series, abandoned cart flow, and post-purchase thank-you creates a solid foundation, and the remaining Klaviyo flows can follow as the business grows. Each flow added brings the brand closer to a fully automated, always-on revenue engine.
FAQ
How many Klaviyo flows should a new store launch first?
A new store gains the most from three flows: the welcome series, the abandoned cart flow, and the post-purchase thank-you. These three cover the key moments of sign-up, hesitation, and purchase, and they need relatively little setup. Once they run smoothly, the store can layer on the other seven.
How long does it take to see results from Klaviyo flows?
Most stores notice results within the first few weeks, because welcome and abandoned cart flows start working as soon as visitors arrive. Flows like winback and replenishment take longer to show impact, since they depend on customers reaching a certain point in their buying cycle.
How often should a store update its flows?
A quarterly review works well for most brands. Seasonal offers, new products, and changing customer behavior can make older copy feel stale. During each review, the team can compare open rates, click rates, and revenue per recipient to decide which emails need fresh subject lines or updated product recommendations.
