The Best Klaviyo Flows to Build, Ranked by What They Actually Return

Most brands build a welcome flow and a cart abandonment flow, watch them earn, and treat the rest of lifecycle marketing as a backlog item. Then someone sells them a post-purchase sequence on the promise that it’s where the real money is.

Klaviyo publishes per-flow numbers that settle this, and they don’t say what that pitch says. Ranked honestly, the best Klaviyo flows are not the ones most brands are told to build next. Read them before you scope anything.

Everything below comes from Klaviyo’s own platform data on its flows. Klaviyo sells the product these figures flatter and BLKDG is a Klaviyo Partner, so treat them as a vendor’s benchmarks rather than independent research. They’re still the best published numbers on Klaviyo flows available anywhere, and they’re specific enough to plan against.

The case for Klaviyo flows over broadcast campaigns is the least controversial thing here, and it’s worth stating precisely because it sets the scale for everything after.

Klaviyo’s 2026 email benchmarks report that “flows generate nearly 41% of total email revenue from just 5.3% of sends, with average revenue per recipient (RPR) that’s nearly 18x higher than campaigns.”

The engagement gap is narrower but still large. Klaviyo reports that “email flows deliver over 3x higher click rates (5.58% vs. 1.69%) and 13x higher placed order rates than campaigns.”

Two caveats before you build a forecast on that. The figures cover “over 183,000 Klaviyo customers,” which is a large base, but the page states no date range, so you can’t tell how current they are. And 41% of email revenue isn’t 41% of revenue.

That second one matters because it’s the mistake this post’s earlier draft made. Email is a channel, and a flow’s share of a channel tells you nothing about the channel’s share of the business.

Ranked by what they return, the best Klaviyo flows fall in an order that changes how most teams sequence a build.

Klaviyo’s abandoned cart benchmark report breaks revenue per recipient out by flow type. This table ranks the Klaviyo flows by what each one returns, and it’s based on “over 143K abandoned cart flows sent in 2023.”

That data is from 2023. At the time of writing that makes it roughly three years old, which is long enough for send volumes, inbox placement and buyer behavior to have moved. Use it as a ranking, not as a forecast for your own store.

Read as a ranking of Klaviyo flows, it says something blunt. The two Klaviyo flows nearly everyone already has are the two highest earners per recipient, and the flow most often sold as the upgrade earns about a ninth of what abandoned cart does.

Among the Klaviyo flows benchmarked, abandoned cart also converts best, at 3.33% on average, rising to 7.69% for the top 10%.

“We already have those” is not the same as “those are finished.”

Look at the spread between average and top decile in the table. Abandoned cart goes from $3.65 to $28.89, and welcome from $2.65 to $21.18. That’s roughly an eightfold gap between a flow that exists and a flow that’s been worked on.

No new Klaviyo flow you add to the backlog has that much headroom. Before you build a fifth Klaviyo flow, the honest question is whether your two biggest earners are near the average or near the top, and most teams have never checked.

Klaviyo reports that “nearly 48% of flow-driven email revenue comes from new buyers,” which is a useful sanity check on where your automation revenue is actually coming from. If almost half of it lands on people buying for the first time, the flows that greet and recover new buyers are load-bearing rather than solved.

If welcome and cart are tuned and you’re genuinely choosing what to add, browse abandonment has the strongest published claim at $1.07 average revenue per recipient and $7.21 for the top decile.

It works for the same reason the cart abandonment flow does. It catches someone who has already shown intent, while the intent is still fresh, which is a much shorter distance to a purchase than reactivating someone who has drifted.

It’s also the flow most affected by list quality and identification. A browse abandonment flow can only fire for someone you can recognize, so its ceiling is set by how much of your traffic is identified, which is a data problem before it’s an email problem. That groundwork sits upstream of the flows, and it’s what a properly built Klaviyo setup is for.

Post-purchase sits at the bottom of Klaviyo’s table at $0.41 average revenue per recipient. Build it anyway, and be clear-eyed about why it sits last among the benchmarked Klaviyo flows.

Revenue per recipient is the wrong scoreboard for a Klaviyo flow whose job is the second order rather than this one. A post-purchase sequence is spending on customers you’ve already paid to acquire, so its return shows up as repeat rate, time to second order, and lifetime value. None of those appear in an RPR column.

That’s a defensible reason to build it. “It’s where the real money is” is not, and Klaviyo’s own data is the thing that refutes it.

Replenishment and win-back need a bigger caveat: Klaviyo’s benchmark report doesn’t include them. There’s no published per-recipient figure to rank them against the four flows above, so anyone quoting you one is quoting something else. Judge them on your own reorder cycle and lapse window instead.

Replenishment is the easier of the two to justify, because the timing is a property of your product rather than a guess. If you sell something consumed on a predictable cycle, the send date is arithmetic. If you don’t, the flow has nothing to key off and it becomes a generic nudge.

The order below follows from the data rather than from a template, and it applies whether you run two Klaviyo flows or ten.

First, measure what your existing welcome and cart Klaviyo flows return per recipient and compare them to the table above. That comparison is the whole diagnosis, and it takes an afternoon.

Second, fix whichever of the two is furthest below its benchmark. The headroom between average and top decile is larger than the entire average value of any Klaviyo flow further down the list.

Third, add browse abandonment, assuming enough of your traffic is identified for it to fire.

Fourth, add post-purchase, measured on repeat rate rather than RPR, and set that expectation with whoever approves the budget before you build it rather than after.

Then look at replenishment if your product has a real reorder cycle, and win-back once you have enough lapsed customers for the segment to be worth addressing.

Trigger mechanics are a separate subject and a solved one. If you’re deciding how any of these should actually fire, basic versus advanced triggers covers it.

Two ways Klaviyo flows stop earning are worth naming, because both look like success on a dashboard.

The first is attribution overlap. A shopper who gets a browse abandonment email, then a cart abandonment email, then buys, can be credited to both flows depending on your attribution window. Stack enough Klaviyo flows and your reported flow revenue climbs while your actual revenue doesn’t.

The second is send fatigue. Every Klaviyo flow you add competes for the same inbox, and the marginal flow is the one most likely to push someone to unsubscribe. That cost lands on every future send, including the two Klaviyo flows that were earning most of your money.

Neither argues for fewer Klaviyo flows. Both argue for measuring flow revenue against total revenue rather than against itself, which is the same discipline any conversion funnel analysis applies to the rest of the journey.

The ranking of Klaviyo flows is not the build order most brands are sold.

Welcome and cart earn the most and have the most headroom, browse abandonment has the clearest case for being next, and post-purchase is worth building for reasons that don’t appear in a revenue-per-recipient column. Replenishment and win-back aren’t benchmarked at all, so judge them on your own data.

If you’d rather have someone measure your existing flows against these benchmarks and tell you which one is leaking, that’s what our Klaviyo email marketing work starts with.
