Klaviyo Email and Lifecycle Marketing
Email is the only channel you own outright, and most ecommerce brands use it like rented media.
Every other channel charges you again for the same customer. Email does not. We build Klaviyo as owned infrastructure: store data flowing in properly, a segmented list, a library of automated flows that catch revenue at the exact moments it is otherwise lost, and a campaign calendar that earns attention rather than spending it. Broadcast reaches everyone; lifecycle reaches the right person at the right moment, and that is where the money is.
The problem
Why most email programmes underperform the channel
Email rarely fails outright. It just settles into a rhythm of sending to everyone, converting a few, and slowly training the rest of the list to ignore you.
Sending to everyone, every time
The same message goes to a buyer from last week and someone who has not opened anything in a year.
The cost · You train your best customers to skim and your worst to unsubscribe, and deliverability pays for both.
Campaigns running, no flows built
The calendar is full but nothing is triggered by behaviour, so an abandoned checkout, a failed payment or a lapsed buyer gets nothing at the moment it matters.
The cost · The highest-intent revenue in the channel is left uncollected.
List growth left to the checkout
Subscribers arrive only when someone buys, so the list only grows as fast as sales already do.
The cost · Email cannot help acquisition, only repeat purchase.
Deliverability treated as somebody else's problem
Nobody prunes the unengaged, watches the complaint rate or warms a new sending domain.
The cost · Your reach falls quietly, and the first visible symptom is a revenue drop nobody can explain.
Open rate mistaken for performance
Reporting leads with opens, a metric privacy features inflate.
The cost · The programme is steered by the least reliable number available.
Klaviyo disconnected from the store
Purchase, browse and checkout events do not flow in properly, so segmentation is guesswork.
The cost · You cannot trigger on behaviour, which means you cannot do lifecycle at all.
Our methodology
How we engineer a lifecycle programme
Built in a deliberate order: get the data in, get the list clean, build the flows that catch revenue automatically, then layer campaigns on top of a foundation that can carry them.

Audit the account and the list
Evidence firstWhat is actually sending, what the list looks like underneath the total, where deliverability stands, and which revenue the current setup is not catching.
Fix the data foundation
Behaviour before messagesWire the store, forms and any CRM so purchase, browse and checkout events land in Klaviyo. Without those events there is no segmentation and no lifecycle.
Build the flows that catch revenue
Automation first, campaigns secondWelcome, abandonment, post-purchase, winback, cross-sell and payment recovery. These run once and keep earning, which is why they come before the calendar.
Segment on what people actually did
Not on who they arePurchase history, product affinity, engagement recency and any compliance or geographic rules, so a message can be relevant rather than merely addressed.
Run a campaign calendar worth opening
Earn the inboxA planned cadence tested on subject line, send time and offer, with suppression rules that protect the list from the calendar.
Protect deliverability and measure honestly
The unglamorous partOngoing hygiene, sunset rules and complaint monitoring, with reporting that leads on attributed revenue and conversion rather than on opens.
What is included
What is included
The owned channel, built and run end to end.
Lifecycle automation
The flow library that earns continuously once built, plus the segmentation it runs on.
Campaign programme
Calendar, production, testing cadence and suppression rules.
Migration to Klaviyo
Where you are moving from another platform: data mapping, consent integrity, flow rebuild and deliverability warm-up, covered here rather than as a separate project.
Capture and forms
On-site sign-up, quizzes and survey integrations feeding segmented lists and follow-up flows.
Deliverables
What you get
Concrete artefacts, not a slide deck. Everything is documented and handed over cleanly, nothing is locked to us.
Account and list audit
What is sending, what is not, and what the current setup is leaving on the table.
Data and integration layer
Store, form and CRM events flowing into Klaviyo so behaviour can trigger messages.
Lifecycle flow library
The automated sequences that catch revenue at the moments it is otherwise lost.
Segmentation architecture
Behavioural and purchase-based segments the whole programme runs on.
Campaign calendar and testing cadence
A planned schedule with a structured approach to what gets tested next.
Revenue reporting and deliverability monitoring
Attributed revenue by campaign and by flow, plus the health metrics that protect it.

The process
How we work together
Sequenced so the data foundation comes before the flows, and you always know what is next and why.
Growth Audit
Week 0We read where the channel is leaking revenue and agree what to build first.
Account audit and plan
Weeks 1 to 2The account, the list and deliverability assessed, and the flow and segment plan agreed.
Data and flow build
Weeks 2 to 6Events wired in, then the flow library and segmentation built on top.
Campaign cadence live
Weeks 4 onwardA planned calendar with testing and suppression rules that protect the list.
Optimise

Is this for you
Where this is the right call, and where it isn't.
We'd rather tell you it's not the right time than sell you the wrong thing.
A strong fit if
- You have an existing customer base or list you are under-using
- You sell something people buy more than once
- You are sending campaigns but have few or no automated flows
- You want revenue from a channel you already own
Probably not yet if
- You have no list and no traffic to build one from
- You sell a genuine one-time purchase with no repeat or referral path
- You want volume sending without segmentation or hygiene
- You cannot connect your store to Klaviyo
FAQ
Questions, answered.
Klaviyo email marketing is substantially more than newsletters. A newsletter is a broadcast to everyone at a time you chose. Lifecycle marketing is a set of messages triggered by what a specific person did, sent at the moment their intent is highest, which is why flows typically convert at a far higher rate per recipient than broadcasts do. Most of the revenue in a mature programme comes from the automated half.
Campaigns and flows do different jobs. A campaign is a one-off broadcast you schedule, and it drives volume and awareness across the list. A flow is an automated sequence triggered by behaviour, such as an abandoned checkout or a lapsed buyer, and it runs continuously without further work. Campaigns generate reach; flows generate efficiency. A programme needs both, and flows should usually be built first.
Email marketing should be measured on attributed revenue, conversion rate and revenue per recipient, with open rate treated as directional only. Privacy features on some mail clients register opens automatically, which inflates the number in ways that vary by audience. Open rate is useful for comparing your own sends over time; it is not a reliable performance measure on its own, and we do not report it as one.
We specialise in Klaviyo for ecommerce because its native integration with store events makes behavioural triggering and revenue attribution far more reliable than a general-purpose sending tool. For B2B lifecycle and CRM-driven marketing we work in HubSpot instead, which is a separate service. Specialising in two platforms properly is a deliberate choice over claiming to work in all of them.
Yes, and migration is covered under this service rather than sold separately. A migration involves considerably more than exporting contacts: consent status, engagement history and automation logic all have to be deliberately mapped rather than left behind, and sending reputation does not transfer, so new infrastructure has to be warmed in stages.
Klaviyo works differently on a small or unengaged list, and pretending otherwise is how programmes get damaged. On a small list the immediate priority is capture and flows, because a welcome sequence and an abandonment flow earn from every new subscriber. On an unengaged list the first job is hygiene, which usually means sending to fewer people before sending to more, since reach depends on reputation.
