Retention · Klaviyo email, SMS and WhatsApp

The revenue doesn’t stop at the first purchase

Flows that run without supervision, campaigns that do not burn the list, and a clear line between the two.

  • Klaviyo
  • Mailchimp
  • Omnisend
  • Attentive
  • Netcore

Lifecycle built on behaviour, not demographics. Measured by cohort, not by send.

Klaviyo and Shopify Deliverability monitored

Watch the team at work

A short example of how our team takes on a brief, from the first call to the results.

What makes a list pay

Everything that goes into a list that earns between campaigns. Named, not implied.

Flow architecture

The sequences that run whether or not anyone is watching. Welcome, browse, cart, checkout and post purchase.

Lifecycle segmentation

Every customer is segmented by lifecycle, purchase behaviour, value and engagement, so messaging, timing and offers are matched to where they are in the customer journey.

Campaign calendar

A rhythm the list can live with. Present enough to matter, segmented enough that unsubscribes do not do the pruning.

SMS where it earns it

Email does the heavy lifting. SMS steps in for moments where urgency, timing or intent can materially change the outcome.

Deliverability

Your messages belong in the inbox. We protect sender reputation with proper authentication, list hygiene and disciplined sending, keeping campaigns healthy as your database and revenue scale.

Reporting by cohort

Revenue tracked by the month a customer arrived, so retention is measured, not assumed.

How we grow with you

From the first audit to long-term retention, you always know what we’re doing, why we’re doing it, and what comes next.

We audit the customer journey

We analyse your data, purchase behaviour, existing flows and retention economics before changing a single message.

We build the lifecycle engine

Email, SMS, WhatsApp and automated flows are structured around where each customer is in their journey, from first purchase to repeat and reactivation.

We run the calendar around the customer

Campaigns, launches and offers are planned around buying cycles, seasonality and customer value, not arbitrary send volume.

We measure what compounds

Revenue is measured across cohorts, repeat purchase and lifetime value, so short-term wins never come at the expense of long-term retention.

Before you get in touch

The things brands usually ask us before we start on their email, SMS and WhatsApp marketing.

Mostly Klaviyo, plus Mailchimp, Omnisend, Attentive and Netcore. We work inside the platform you already use, so nothing is migrated unless it should be.

No. Flows start earning from the first customer who triggers them, and we grow the list alongside them, so with a smaller list the flows simply come first.

Flow fixes usually show within the first few weeks. Campaign rhythm and repeat purchase build over the following months, and every change is reported by cohort.

Yes. Our in-house email designers build every template and campaign, so design, copy and strategy come from one team.

No. Every send is segmented and planned around buying cycles, so your list stays healthy and unsubscribes stay low.
