Not every flow is worth the same. Here are the ones that earn the most.
Some Klaviyo flows earn several times more per send than others, because they catch people at very different moments of intent. Here is how the core flows rank by revenue per recipient, grounded in the brands we audit and Klaviyo's published data, so you build the ones that pay first instead of the ones that are easiest to set up.
Core flows by revenue per recipient
How much each flow earns per send, in tiers. The order holds across the brands we audit and is in line with Klaviyo's published benchmarks, even though the exact figures vary by store, so treat this as the shape, not a scoreboard.
| Tier | Flows | Why they land here |
|---|---|---|
| Highest per recipient | Welcome series, Abandoned cart | They reach people at peak intent, someone who just subscribed or was moments from buying, so each send is worth the most. In our audited fleet these two consistently top the ranking, in line with Klaviyo's published benchmarks. |
| Strong | Post-purchase | The retention engine: education, cross-sell, and the review ask turn one order into the next. Solid revenue per recipient and it compounds, because it lifts the repeat rate that feeds every other flow. |
| High for the right catalog | Replenishment, Back in stock | For consumables and inventory-constrained brands these fire on very high intent, someone about to run out, or waiting on a restock, so they can rival the top tier. Their value depends on whether your catalog creates the trigger. |
| Lower per recipient, high reach | Browse abandonment, Win-back | Colder or earlier intent means each send is worth less, but they reach far larger audiences and recover customers the high-intent flows never see, so they still add up to real revenue. |
| Not a revenue flow | Sunset / list hygiene | Earns almost nothing per recipient by design. Its job is to suppress chronically unengaged contacts so your revenue-driving flows keep landing in the inbox. Profitable indirectly, through deliverability. |
Most profitable means two things at once
Revenue per recipient tells you how efficient a flow is; total revenue tells you how much it actually contributes. They are not the same, and the best flow for your store depends on both. A welcome series earns a lot per send but only reaches new subscribers, so its total is capped by how many people sign up. A browse abandonment flow earns far less per send, but it can reach many times more people, so its total can rival a higher-efficiency flow. That is why the ranking above is the starting point, not the answer. The most profitable flow for you is whichever combination of per-send value and audience size adds up to the most on your account, which is exactly what a dollar-ranked audit surfaces.
Start with the highest-value flow you don't have
The ranking makes the build order simple: the biggest win is almost always a top-tier flow you are missing entirely, not a small improvement to one you already run. For most stores that means making sure the welcome series and abandoned cart flow are built and built well before anything else, because they sit at the top and catch people at peak intent. After the core set is in place, let your catalog decide the next build: replenishment if you sell consumables, back-in-stock if inventory runs tight, post-purchase to lift repeat rate. The essential flows checklist covers the full core set and how to tell which of yours are dead weight.
The only ranking that counts is yours
A general order tells you where to look; it cannot tell you which flow is worth the most on your store, or how much you are leaving on the table by not running it. That depends on your traffic, catalog, and repeat rate. A free Klaviyo audit ranks your flows by the actual revenue each one drives and each one could drive, so you see your highest-value flow, the gaps below it, and the dollar figure attached to closing them. So you build in the order that pays.
Is it safe to connect Klaviyo?
- Read-only. It can read your campaign and flow performance. It cannot send, edit, or delete anything in your account.
- No customer data stored. It works from your metrics, not your subscriber list. Names, emails, and phone numbers are never stored.
- Nothing ships without you. Built emails land as drafts for your review; nothing is pushed to Klaviyo on its own.
- Built by an operator. David Refaeli-Berman ran enterprise email at Chewy, Amazon, Overstock, and Bed Bath & Beyond.
Questions
What is the most profitable Klaviyo flow?
For most stores it is the welcome series or the abandoned cart flow. Both reach people at peak intent, someone who just subscribed or who was moments from checking out, so each send is worth more than a typical email. That said, the most profitable flow for your store is often the high-value one you are not running yet, because a missing flow earns nothing at all.
How do you measure which flow is most profitable?
Two ways, and you need both. Revenue per recipient tells you how efficient a flow is, how much each send is worth. Total revenue tells you how much it actually contributes, which is revenue per recipient multiplied by how many people the flow reaches. A high-efficiency flow that reaches few people can total less than a lower-efficiency flow with a large audience, so profitability is always both numbers together.
Do flows with lower revenue per recipient still matter?
Yes. Browse abandonment and win-back earn less per send than welcome or cart flows, because they catch colder or earlier intent, but they reach much larger audiences, so they add up. They also recover customers the high-intent flows never see. Lower per recipient is not the same as low value; it usually just means the payoff comes from reach rather than from each individual send.
Which Klaviyo flow should I build first?
The highest-value flow you do not already have. For most stores that is the welcome series or abandoned cart if either is missing, since they sit at the top of the ranking and reach people at peak intent. After the core set is in place, the next build is driven by your catalog: replenishment for consumables, back-in-stock for inventory-constrained brands, post-purchase to lift repeat rate.
Is a sunset flow profitable?
Not directly, and that is the point of it. A sunset flow earns almost nothing per recipient because its job is list hygiene, not sales: it quietly suppresses chronically unengaged contacts so your sending reputation stays healthy. It is profitable indirectly, by keeping your genuinely revenue-driving flows and campaigns landing in the inbox.
