Behavioural segmentation
Lists split by purchase history, engagement recency, browse behaviour and predicted value — so what arrives is relevant to that specific person.
Our email marketing services build revenue from the list you already own — email automation flows, drip campaigns, segmentation and deliverability on Klaviyo, Mailchimp and HubSpot. As an email marketing agency, we report on revenue per subscriber, not open rates.

The flows do the heavy lifting — they run continuously, trigger on real behaviour and typically generate a disproportionate share of total email revenue from a small fraction of total sends. Campaigns then layer on top for launches, seasonal pushes and re-engagement.
The ownership argument: an algorithm change can halve your organic social reach overnight and a competitor can outbid you on every keyword. Neither can touch your email list. It is the only audience that cannot be taken away from you.
Every engagement covers all five. Lifecycle flows sit at the centre — the rest make sure they reach the inbox, stay relevant and prove their revenue.
Lists split by purchase history, engagement recency, browse behaviour and predicted value — so what arrives is relevant to that specific person.
Welcome, browse abandonment, cart recovery, post-purchase, replenishment and win-back, each triggered by real behaviour rather than a calendar.
SPF, DKIM and DMARC configured properly, list hygiene, sunset policies and warm-up plans so you reach the inbox rather than the promotions tab.
Subject lines, send times, offers and creative tested with enough volume to be conclusive rather than declared a winner on forty opens.
Reporting on revenue per recipient and per flow, not open rate — because opens stopped being measurable the moment privacy proxies arrived.
Six workstreams, sequenced so deliverability is protected before volume increases — because sending more to a damaged sender reputation makes things worse, not better.
Authentication records, sender reputation, list health, engagement decay and inbox placement testing. You get a clear picture of whether your email is actually arriving before we touch anything else.
Lists rebuilt around behaviour and value rather than acquisition date. This single change usually lifts engagement more than any amount of copywriting.
Welcome, cart and browse abandonment, post-purchase and win-back, each triggered on real behaviour with proper exit conditions so people are not receiving three flows at once.
Templates that render correctly across clients and dark mode, with modular blocks so campaigns can be built quickly without rebuilding layout every time.
A standing test calendar on subject lines, offers, timing and creative — run at volumes that produce conclusive results rather than noise.
Revenue per recipient by segment and flow, list growth net of churn, and deliverability trend — reported monthly so decline is caught early.
ⓘ Deliverability is protected before volume increases — each phase starts only when the one before it is healthy.
We check inbox placement before increasing volume. Sending more from a damaged reputation compounds the problem, and most agencies discover this only after the damage is done.
Our headline metric, not open rate. It cannot be gamed by a clickbait subject line and it maps directly to what the programme is worth.
Automation produces a large share of email revenue from a small share of sends. We build that infrastructure first, then layer campaigns on top.
GDPR, PECR and CAN-SPAM handled properly — consent records, preference centres and clean unsubscribes. A complaint spike costs more than any campaign earns.
Removing unengaged subscribers usually raises revenue, because engagement drives placement. Most agencies avoid it because a smaller list looks worse in a report.
Klaviyo, Braze, HubSpot, Mailchimp or a custom stack — we work in what you already have rather than pushing a migration we happen to be certified in.
Same budget, very different outcomes. Point by point, here’s how a specialist partner compares to a typical agency or doing it in-house.

Privacy proxies made opens unreliable. We measure what still reflects behaviour and maps to money.
The headline number. Revenue generated divided by people mailed, tracked by segment and by flow so you see what is actually working.
How much revenue comes from always-on automation versus one-off sends — the clearest indicator of programme maturity.
Seed testing across major providers, because a campaign that lands in spam reports the same as one nobody opened.
Acquisitions minus unsubscribes and suppressions, so growth is not overstated by counting only new signups.
The proportion of your list that opened or clicked recently, which drives both placement and realistic reach.
Deliverability first, then automation, then volume. Reversing that order is how sender reputation gets damaged.
Authentication, sender reputation, list health, engagement decay and inbox placement testing, plus a review of any existing flows. You get a prioritised plan with the deliverability risks flagged first.
Deliverability report + priority planSPF, DKIM and DMARC configured, list cleaned, suppression rules set and a sunset policy applied. This protects placement before we increase send volume.
Authenticated, healthy sendingCore lifecycle automation built and tested with proper exit conditions, alongside the segmentation architecture that makes each flow relevant to the person receiving it.
Always-on revenue from automationCampaign calendar, standing test programme and monthly revenue reporting. Winners get rolled into flows; losers get retired rather than repeated.
Compounding revenue per recipientStraight answers on deliverability, list size and what email can realistically return.
