The 6 Core Klaviyo Flows Every Ecommerce Store Needs

Quick answer: Before you touch anything fancy in Klaviyo, get six core flows live and well designed: a sign-up pop-up, a welcome series, abandoned cart, abandoned checkout, post-purchase, browse abandonment, and a win-back for inactive subscribers. These run in the background and make money on autopilot. Fancy segmentation and new features can wait. The foundation is what pays for everything else.

Why your flows matter more than your next campaign

Most product founders I meet have Klaviyo “set up.” When you look under the hood, that usually means a basic welcome email, maybe an abandoned cart, both built once and never touched, with creative that has quietly aged a few years.

I get it. Klaviyo is a beast. It never stops. There is always a new feature, a new segment, a new thing to strategise. It is genuinely a full-time job to stay on top of, which is exactly why most founders cannot.

Here is the good news. You do not need to master all of it. You need six core flows working properly. These are the automations that run quietly in the background and generate revenue while you do everything else. Get these right and email stops being a guilt trip and starts being an asset.

Let me walk you through each one, what it does, and why it earns its place.

1. The sign-up pop-up

This is the front door. A pop-up that captures email (and ideally SMS) in exchange for a small incentive, usually a first-order discount or a genuine reason to join.

Without it, you are paying to send traffic to your site and letting most of it leave without ever hearing from you again. The pop-up turns anonymous browsers into subscribers you can actually talk to. Every flow below depends on it doing its job.

2. The welcome series

When someone joins, the worst thing you can do is go quiet. The welcome series is your first impression and often your highest-converting flow.

It does more than deliver the discount code. It introduces who you are, what you stand for, and why your product is worth their money. For founder-led brands especially, this is where you show your face and tell your story, because people buy from people, not logos.

A good welcome series warms a brand-new subscriber from “just signed up” to “ready to buy” without you lifting a finger after it is built.

3. The abandoned cart flow

Someone added a product, then left. That is the highest-intent moment you get. The abandoned cart flow reminds them, handles the small hesitation, and brings them back to finish.

This is usually the first flow founders think of, and for good reason. It recovers sales that were almost lost. If yours is missing or stale, you are leaving easy money on the table every single day.

4. The abandoned checkout flow

This is the one people confuse with abandoned cart, and skipping it is a mistake. Abandoned checkout fires when someone got further, all the way into the checkout, and still did not complete.

That shopper is even closer to buying than a cart abandoner. Something tiny stopped them: a shipping cost, a distraction, a wobble. A separate, well-timed nudge here recovers orders that a cart flow alone would miss.

5. The post-purchase flow

The sale is not the end. It is the start of a repeat customer if you handle it well.

A post-purchase or thank-you flow confirms the order, sets expectations, and makes the buyer feel good about what they just did. Over time it is where reviews, referrals and second orders come from. Repeat buyers are cheaper to sell to and worth far more, and this flow is how you build that base.

6. Browse abandonment and the win-back

Two flows that quietly round out the foundation.

Browse abandonment catches the shopper who looked at a product but never added it to cart. Lower intent than an abandoned cart, but still a warm signal worth a gentle follow-up.

The win-back targets subscribers who have gone quiet, usually after about 90 days of no engagement. A well-built win-back gives them a reason to come back before they drift off completely. It is also the smart cousin of aggressively pruning your list, you try to re-earn attention before you give up on it.

That is the six. Pop-up, welcome, abandoned cart, abandoned checkout, post-purchase, browse abandonment and win-back. Build these properly and you have an engine that sells without you in the room.

The part everyone underestimates: design

Here is something founders rarely hear. The flows working is only half of it. How they look is the other half, and at a certain price point it is not optional.

If your brand sells premium products, your emails cannot look DIY. By DIY I mean generic, blocky, clearly built by someone who is not a designer. Your emails should scream your price point, the same way your packaging and your website do.

This matters even more when your customer is not a 22-year-old who lives on their phone. Older, higher-value demographics notice when an email looks cheap, and it quietly undermines the price you are asking them to pay.

One honest note on quality: emails do not need website-grade image files. They are viewed small, so pulling an image straight from your site is usually fine. The thing to invest in is the layout and the strategy, not chasing the perfect resolution.

Why rebuild instead of patch

If your flows are basic and a few years old, the temptation is to tweak them. Often a rebuild is the better call.

A rebuild lets you fix the strategy, the timing and the design all at once, so everything is congruent. Then your newsletters feed the flows, the flows feed the newsletters, and the whole system compounds. Patching one tired email at a time never gets you there.

And no, you do not need the giant package straight away. Get the core engine built first. It takes a bit of effort up front, then it starts generating its own money. Once that foundation is humming, you can layer on deeper segmentation and optimisation. Foundation first, fancy later.

Key takeaways

Six flows form the foundation: pop-up, welcome series, abandoned cart, abandoned checkout, post-purchase, browse abandonment and win-back. They run in the background and make money on autopilot. Design is not a nice-to-have. At a premium price point, DIY-looking email costs you sales. When flows are basic and dated, rebuilding beats patching, and you do not need the biggest package to start. Get the foundation right, then add the advanced stuff.
