Klaviyo Flow Setup and Architecture

The Automation Layer, Built and Run for You.

In our best-documented rebuild, flows drive about 70% of email revenue, around the clock. We build that machine: every trigger, split, and send engineered around how your customers buy, then tested monthly. You keep campaigns. We run the automation underneath. Every partnership includes:

How it works

There Are 20 Core Flows. Most Brands Run 5 of Them Badly.

"Set and Forget" Is How Flows Die.

A welcome series and an abandoned cart flow is not an automation strategy. It is the default setting. Klaviyo’s 2026 benchmark data shows flows producing about 41% of email revenue from 5.3% of sends, with revenue per recipient roughly 18 times higher than campaigns. Yet most accounts we open run a quarter of the 20 core flows, untested and untouched since launch.

That is how flows decay: built once, then left alone while products, prices, and the audience change. We treat your flows like a portfolio, not a finished to-do list. Every month each flow is reviewed against its own history. Winners get expanded, laggards get rebuilt, and new flows join when the data says your audience is ready.

The Depth Layer: Flows Your Competitors Don't Know Exist.

Abandoned cart is table stakes. Every brand has one, so every inbox ignores them. The revenue hides one layer deeper: predicted next-order flows that land a reorder prompt the week a customer runs low, milestone flows that reward a customer two purchases before they would have churned, back-in-stock and low-inventory triggers, VIP tiers for your top decile, and sunset sequences that protect your sender reputation.

These flows take real architecture: conditional splits, profile properties, and predictive analytics. That is why most agencies skip them, and why we lead with them.

What you get

How the Automation Layer Gets Built

Four workstreams, run in sequence and then in parallel. Rescue revenue first, depth second, always compounding:

Why it works

Why Brands Hand Us Their Automation

Revenue-Weighted Build Order

No alphabetical to-do lists. Flows get built in the order they pay: rescue first, replenishment next, depth after, sequenced by what your account is leaking most.

Runs Alongside Your Team

You keep campaigns, promos, and brand sends in-house. We own the automation layer underneath, with smart sending rules so the two never collide.

You Own the Machine

Every flow, split, and segment is built in your account and documented as we go. Part ways tomorrow and the engine keeps earning.

“We’ve worked with a few agencies that treat you like just another invoice. Emailium is different. You can tell these guys just love what they do. They are always pinging us with new ideas or small tweaks to squeeze out better performance, rather than waiting for us to ask. The revenue jump has been great, obviously, but the energy they bring to the brand is what actually keeps us around.”

FAQ

FAQs About Advanced Flow Architecture

Thinking about handing us your automation layer? These are the questions we get asked most:

End-to-End means we run everything, campaigns included. Flow Architecture means we own the automation layer while your team keeps campaigns. If you do not have campaign capability in-house, End-to-End Account Management is the honest recommendation, and we will make it.

No, and anyone who says you do is selling flow builds by the pound. The audit decides: a two-SKU consumable brand needs replenishment depth, not back-in-stock logic. You build what your customer behavior justifies, and the map shows the rest for when you are ready.

The audit answers that per flow. Some get kept and tested, some get restructured, and some get deleted, because a flow firing at the wrong moment is worse than no flow. Most accounts land on a mix, and you see the reasoning for every call.

Rescue flows go live inside two weeks and typically show revenue immediately, which is why they always come first. The depth layer compounds over the following 60 to 90 days. Flow revenue in our best-documented rebuild grew 452% across five months of this sequence.

Monthly partnerships run on revenue share: a pre-agreed percentage of the email revenue we generate, tracked in your own Klaviyo attribution. A flow that decays costs us money too, which is why nothing gets set and forgotten. Exact terms are set after your Health Score.
