The Klaviyo Email Flows Every Shopify Brand Must Have Running Before Their Next Ad Campaign

You are about to launch an ad campaign. Before you spend a penny, answer this: when a visitor lands on your store, gets interested, and leaves without buying, what happens? For most brands the honest answer is nothing. They vanish, and the money you paid to bring them is gone. Running ads to a store with no email capture and no recovery flows is pouring water into a bucket with no bottom, and it is the most common reason ad spend underperforms.

This post covers the Klaviyo flows every Shopify brand must have running before the next campaign goes live. These are the automations that catch and convert the traffic you are about to pay for, working in the background long after the ad spend stops. Get them running first and every pound you spend on ads works harder.

Why flows matter more than the campaign you are about to send

There are two kinds of email in Klaviyo. Campaigns are the one-off sends you write and broadcast. Flows are the automated sequences that trigger off a customer’s behaviour: they sign up, they abandon a cart, they place an order. Campaigns need your time every week. Flows are built once and then earn money on autopilot for every visitor, forever.

This distinction is the whole point. The traffic your ads bring does not buy on the first visit. The large majority leave, and without a flow capturing and recovering them, that interest evaporates. A brand with strong flows monetises the same ad spend two or three times over, because the visitor who did not buy today gets a welcome sequence, an abandoned cart reminder, and a reason to come back. The brand without flows paid for that visitor once and lost them.

This is why flows come before campaigns and before ads. Across the brands we manage, email automation alone generates around 15% of total revenue, and almost all of it comes from flows, not broadcasts. That is revenue earned with no ongoing send effort, from traffic you already paid to acquire. We build this engine as part of Klaviyo email automation and lifecycle marketing.

The flows you must have live before you spend on ads

These are not optional extras. If your ads go live before these are running, you are leaving the majority of your acquired traffic uncaptured.

1. The welcome flow

Triggered when someone subscribes, usually through a signup form offering a first-order incentive. This is your highest-performing flow because it catches people at peak interest. It should introduce the brand, deliver the incentive, handle the common objections, and lead to a purchase across a short sequence of emails. Most of your new email revenue starts here.

2. The abandoned cart flow

Triggered when someone adds to cart and leaves without buying. These are your warmest non-buyers, people who got all the way to the cart. A two or three email sequence reminding them, handling hesitation, and offering help recovers sales that would otherwise be lost entirely. This single flow often pays for the whole email programme.

3. The browse abandonment flow

Triggered when someone views products but does not add to cart. Lower intent than an abandoned cart, but far higher volume, and most brands never set it up. A gentle nudge showing what they looked at brings a meaningful share of browsers back. This is found money most stores leave on the table.

4. The post-purchase flow

Triggered after an order. This is where you turn a first-time buyer into a repeat customer, which is the cheapest growth there is. Confirm the order, set delivery expectations to reduce anxiety and support tickets, then follow up to drive the second purchase and request a review. Retention starts the moment someone buys, not months later.

5. The win-back flow

Triggered when a customer has not purchased in a set period. It costs far less to win back a lapsing customer than to acquire a new one through ads. A win-back sequence re-engages them before they are gone for good. This flow quietly protects the customer base you spent so much to build.

The flow most brands get wrong: capture, before any of it can work

Here is the failure that makes the whole system pointless. You can build perfect flows, but if you are not capturing email addresses, the welcome and browse flows have nobody to send to. The capture rate is the foundation, and most stores treat it as an afterthought.

Your signup form is the most important conversion point in your email programme. A weak one, a tiny footer box asking people to “subscribe to our newsletter”, captures almost nobody. A strong one offers a genuine reason to give an email, a first-order discount or something of real value, appears at the right moment, and is tested on mobile where most visitors are.

Get the capture rate up and every downstream flow has more people to convert. This is the leverage point: doubling your capture rate doubles the input to your entire automated system. Before you launch ads, make sure your signup form is doing real work, because the ads are about to send you the exact traffic that form is meant to catch. We treat capture as the first build, not the last, in every email automation engagement.

Common mistake

Launching ads first and “getting to email later”. By the time you set up flows, you have already paid to acquire thousands of visitors who left and will never be contacted again. That traffic is gone, and you cannot get it back. The flows have to be live before the spend, so the very first visitor your ad sends is captured and worked. Email built after the campaign is email that missed the campaign.

The numbers that tell you a flow is healthy

Once your flows are live, you need to know whether they are actually working. Use these as working benchmarks rather than precise rules, because they vary by brand and product, but they tell you quickly whether a flow is pulling its weight.

Welcome flow. This should be one of your highest-converting flows because it catches people at peak interest. Open rates well above your campaign average are normal here, and it should drive a healthy share of first orders. If your welcome flow is not converting, the usual cause is a weak incentive or too long a wait before the first email.

Abandoned cart flow. Recovering a meaningful percentage of abandoned carts is the mark of a working flow. If recovery is near zero, check that the flow triggers quickly, that the first email goes out within an hour, and that it handles the real reasons people hesitate rather than just saying “you left something behind”.

Browse abandonment flow. Lower conversion than cart recovery, because intent is lower, but very high volume, so it adds up. Treat any revenue here as upside, since most brands earn nothing from browsers at all.

Post-purchase flow. Judge this on repeat purchase rate and review generation, not immediate sales. Its job is the second order, which is the cheapest revenue you will ever earn.

The deeper point: do not judge email by your manual campaigns. Open your Klaviyo flow reporting and look at the revenue each flow produces on its own. That automated revenue, earned with no weekly effort, is the real engine, and it should grow steadily as more traffic enters the flows. If it is flat, your capture rate is the bottleneck, not the flows.

What good looks like

A Shopify brand ready to advertise has, at minimum, a welcome flow, an abandoned cart flow, a browse abandonment flow, and a post-purchase flow live, fed by a signup form that captures a healthy share of visitors. With that running, every ad pound buys a visitor who is then captured, nurtured, and recovered automatically, which is why the same budget produces far more revenue than it does for a brand with no flows. Email becomes a channel that earns around 15% of revenue with no weekly effort, on top of whatever your campaigns add.

What to do next

Before your next ad campaign goes live:

Build a strong signup form with a real incentive and test it on mobile.
Launch the welcome flow to catch new subscribers at peak interest.
Launch the abandoned cart and browse abandonment flows to recover warm traffic.
Launch the post-purchase flow to turn first-time buyers into repeat customers.
Add a win-back flow to protect the customer base you are paying to build.

The campaign you are about to run will send you traffic whether or not you are ready to keep it. Build the flows first and you keep it. Skip them and you rent it.
