Klaviyo and email

The cheapest revenue you have is the list you already paid for.

Every euro of media leaves something behind: an address, a browse, an abandoned basket. Flows and campaigns are how that becomes a second and a third order without buying the same customer twice. It’s the one channel where the audience is already yours.

ProofOn a brand we own

We wrote the flows on our own brand, then sold the brand.

Curated Chrome was ours. Across November and December 2024 the store took $174 771.71, email was credited with $55 825.00 of it, and 72.7 percent of that came from always on flows rather than campaigns sent by hand. Revenue on the days nobody pressed send. The case study opens the Klaviyo dashboards behind it. Why we measure it against the store is in a separate note.

Inside the month

Four things happen every month, whatever else does.

Flows don’t stay tuned, lists don’t stay clean and inboxes don’t stay open. The work is what keeps all three from drifting while you’re looking at something else.

How it starts

The order we work in, from the week you say go.

  1. 01Week 1

    We audit the account and the inbox

    Every flow, every segment, list health, sending domain and deliverability.

  2. 02Week 2

    The revenue flows go in first

    Welcome, browse abandon, cart, checkout, post purchase, winback and back in stock.

  3. 03Week 3

    Segments, then a calendar

    The list split into groups worth talking to separately, and a campaign calendar booked against the trading year rather than against whoever happened to remember.

  4. Every week after

    Send, split, read, repeat

    Campaigns out, subject lines and offers split tested, flows tuned on what came back.

The craft

What actually moves the account.

01

Flows before campaigns, always

A campaign sells once. A flow sells while you’re asleep, every day, forever. We build the seven that carry the revenue first and only then argue about the newsletter.

02

Segments that mean something

First time buyer, repeat buyer, lapsed, high value, browsed and didn’t buy. Sending everyone the same thing is what taught your list to stop opening.

03

Deliverability treated as infrastructure

Authentication, sending domain, warm up, sunset policy and engagement tiers. Inbox placement is the ceiling on every other decision in the account, so it gets set first.

04

Written like the brand, not like the tool

Klaviyo ships good defaults and every store using them looks the same. Yours gets a template system built from your own site, so the email and the shop are one thing.

05

Timing set by behaviour, not by a calendar

Delays, splits and conditions that read what somebody actually did. A cart reminder that lands ninety minutes later does work that the same email can’t do the next morning.

06

Measured against the store, not the platform

Klaviyo will happily claim an order the ads paid for. We set attributed revenue next to total store revenue, so the number in the report is one you can defend to anybody.

What lands on your side

What you get every month.

Every flow built and live

Not a plan for flows. Built in your account, styled to your brand, switched on.

A campaign calendar you can see

Booked ahead against the trading year, so nothing goes out because it was Tuesday.

Deliverability held on purpose

Authentication, warm up, sunset and engagement tiers, checked rather than assumed.

The account stays yours

Klaviyo, the lists, the templates and the flows, in your name from the first day.

What it costs

Two ways to pay for the flows and the calendar.

A fixed monthly fee, or a commission on the growth instead of most of that fee. Email is the cheapest channel you own, so the number is small either way, and it’s agreed before anything is built.

The same fee every month
Model one

A fixed monthly fee

One amount, agreed before anything starts and unchanged when a month turns out heavier than the last one.

  • Set by what the business needs, never by the hour
  • No percentage of your media budget on top
  • Reviewed once a quarter, never mid-month
A smaller base, a share of the growth, a cap
Model two

A commission on the growth

Most of the fixed fee comes off and we take a share of what the work adds, measured against the same month a year earlier.

  • Read from your own numbers, not from what a platform claims
  • Capped, so a very good month never becomes a penalty
  • You keep the accounts either way, permanently

There is no rate card. Which structure fits, and what the number inside it is, depend on what the business actually needs: margin, seasonality and how much growth is already in motion. We’ll tell you which one we’d recommend and why, in the same document as the number.

Questions

The questions that come up first.

Flows or campaigns first?

Flows, always. A campaign sells once and a flow sells while you are asleep. We build the seven that carry the revenue first and only then argue about the newsletter. On our own brand, across November and December 2024, 72.7 percent of email revenue came from always on flows rather than campaigns sent by hand.

Which flows actually carry the revenue?

Welcome, browse abandon, cart, checkout, post purchase, winback and back in stock. Those seven get built and then held, with a performance review and a tuning pass every month.

How many campaigns go out, and who writes them?

Two to four a week, on a calendar rather than when there is time, and we write them. Every campaign carries a subject line or offer split, so the calendar keeps teaching the account something.

Open rates fell off a cliff. Is that the writing or the inbox?

It is the first question we answer, before rewriting anything. Deliverability is treated as infrastructure: authentication, sending domain, warm up, sunset policy and engagement tiers, checked every month against real inbox placement.

How is the email work priced?

A fixed monthly fee, or a commission on the growth instead of most of that fee. Email is the cheapest channel you own, so the number is small either way, and it is agreed before anything is built.

What if our list is small?

Then flows matter more, not less. Every euro of media leaves an address, a browse or an abandoned basket behind, and flows are how that becomes a second and a third order without buying the same customer twice.
