There is a quiet truth about email marketing that most ecommerce founders learn the hard way. The campaigns you sweat over every week, the promotions, the new product launches, the seasonal sales, drive only a fraction of your email revenue. The real money is in automation. Industry data from Klaviyo shows that automated flows generate close to 41 percent of total email revenue from just over 5 percent of total sends. Read that line again. Roughly one out of every twenty emails your store sends is doing nearly half the work.
That is the unfair advantage of flows. They run in the background, every single day, while you focus on running the rest of your business. The catch is that you have to build the right ones, in the right order, with the right logic. Skip a flow or build it badly and you are leaving real revenue on the table every month, often without even realizing it.
If you run an ecommerce store on Shopify, WooCommerce, BigCommerce, or any platform connected to Klaviyo, these are the seven core flows that earn the most money for the brands we work with. We have arranged them in the order most stores should build them, starting with the ones that pay back fastest.
1. The Welcome Flow
This is the most important flow in your entire account. The welcome flow is the only series of emails where every single recipient has actively raised their hand and said yes, I want to hear from you. Engagement rates are sky high. Open rates regularly land between 50 and 60 percent. Conversion rates often outperform every other flow in the account.
A good welcome flow is not one email saying thanks for signing up. It is a structured sequence of three to five messages that introduces your brand, tells your story, sets expectations, and gently moves the subscriber toward their first purchase. The first email should land within minutes of signup, because intent fades fast. The second should arrive a day or two later, building trust and value. The rest should keep the conversation going while the offer is still warm.
The mistake we see most often is treating the welcome flow as an afterthought. A single discount code in a plain email is not a welcome flow. It is a missed opportunity.
2. The Abandoned Cart Flow
Roughly seven out of every ten shoppers who add a product to their cart will leave without buying. That is not a problem unique to your store. It is the global average across ecommerce. The good news is that a well built abandoned cart flow can recover a meaningful share of those lost sales because the shopper has already shown clear buying intent.
A strong cart flow usually has three messages. The first goes out within the first hour, reminding the shopper what they left behind. The second goes out about 24 hours later, often with social proof or a soft nudge. The third, sent two or three days later, can include a small incentive if your brand permits it, though many premium brands skip discounts in this flow entirely to protect their margins and brand positioning.
The flow needs careful filter logic. If a customer completes the purchase, they should exit the flow immediately. If they buy a different product, the flow should know. These small details are where most founder built abandoned cart flows quietly leak money.
3. The Browse Abandonment Flow
This is the most underused flow in ecommerce email marketing, and it is also one of the most profitable when set up well. A browse abandonment flow triggers when a known subscriber views a product page but does not add anything to their cart. It captures shoppers earlier in the funnel, before they have even committed to considering a purchase.
Because intent is lower than abandoned cart, you have to be subtler. A great browse abandonment email feels less like a sales pitch and more like a helpful follow up. It might highlight what makes the product special, share a customer review, or suggest similar items the shopper might also like. The goal is to keep your brand in their mind for the day or two it usually takes them to decide.
Setting this flow up properly requires onsite tracking and a clean Klaviyo integration. Most new stores miss this entirely, which is exactly why launching it can feel like finding hidden revenue.
4. The Abandoned Checkout Flow
This flow sits between abandoned cart and a completed purchase. It triggers when a shopper has reached the checkout page and entered enough information that Klaviyo can identify them, but they have not finished the order. Intent here is the highest of any flow in your account. These are people who were one button away from buying.
Because intent is so high, this flow should send quickly. The first email often goes out within 15 to 30 minutes. Many brands keep it short and helpful, focusing on practical reasons people abandon checkout, like shipping concerns, payment friction, or a moment of distraction. A simple one click link back to their saved checkout is often all that is needed.
The abandoned checkout flow tends to have one of the highest revenue per recipient figures in the entire account. If you are not sending it yet, this is usually the fastest revenue win for any store.
5. The Post Purchase Flow
This flow is where smart brands separate themselves from average ones. The post purchase flow runs after a customer completes a purchase, and its job is not to sell another product right away. It is to deliver a great experience, set expectations for shipping, thank the customer, ask for a review at the right moment, and lay the groundwork for a second purchase.
A great post purchase flow can include a thank you message, a shipping update, a how to use guide, a request for a review, and a soft introduction to related products or your community. Spread the messages over two to four weeks. The goal is to make the customer feel cared for, not chased.
Brands that invest in post purchase flows see meaningful lifts in repeat purchase rates and lifetime value. In ecommerce, where acquisition costs keep rising, that compounding revenue is one of the most valuable things you can build.
6. The Winback Flow
Every list has subscribers who used to buy but have gone quiet. The winback flow is your structured attempt to bring them back before they slip away for good. It typically targets customers who have not purchased in 60, 90, or 120 days, depending on your average purchase cycle.
A good winback flow acknowledges the gap warmly without being awkward. It might lead with a we miss you message, share what is new with the brand, surface popular products, and end with a meaningful incentive if the customer still has not returned. The key is sequencing the messages so the customer feels remembered, not pestered.
Winback is also where smart list hygiene begins. If a subscriber does not respond to your winback sequence at all, that is a strong signal that they should be moved out of your engaged segments. Klaviyo charges based on active profiles. Keeping disengaged subscribers in your main sending list quietly inflates your costs and hurts your sender reputation.
7. The Birthday Or Anniversary Flow
This is the smallest flow on the list and often the last one stores build, but it consistently outperforms expectations. A birthday or signup anniversary flow sends a small celebration to your subscriber on their special day. It builds emotional connection, drives a quick burst of revenue, and reinforces that your brand actually pays attention.
The flow itself is simple. One or two emails, sent on the day or just before, with a small offer or a thoughtful message. The setup work is in collecting birthday information at signup or post purchase, which requires planning your forms and properties from the start.
For brands in beauty, fashion, wellness, or lifestyle, this flow performs especially well. Customers in these categories often expect a personal touch, and a birthday note delivers exactly that with almost no ongoing effort once it is built.
Build Them In The Right Order And Your Email Channel Compounds
These seven flows are not a wishlist. They are the foundation of a serious ecommerce email program in 2026. Each one captures a different moment in the customer journey, from the first visit to the loyal repeat purchase. Together they form a system that quietly earns revenue every day, without you having to think about it.
The order matters too. Start with welcome, abandoned cart, and browse abandonment. These three alone can transform a new store’s revenue in the first month. Then add abandoned checkout and post purchase for the next level of impact. Finally, layer in winback and birthday to round out the system.
