What we measure
No vanity metrics. No invented results.
We've been honest since day one: the numbers below are the ones we hold ourselves to on every engagement — not promises of past results.
Flow revenue share
The share of total email revenue driven by automations. Industry leaders run 30–45% of email revenue through flows — this is the biggest lever we look at first.
Revenue per recipient
How much each subscriber is worth per send. We optimise the audience, the offer and the cadence to lift it every month.
List growth & hygiene
Consistent growth plus active list-hygiene — the two things that protect your sender reputation long term.
Deliverability
Bounce rates, spam complaints and inbox placement. If it doesn't land, nothing else matters.
Why brands work with us
The agency model, minus the parts everyone hates.
Free audit, no lock-in
See the plan before you commit. Stay because of results, not because of a contract.
Speed as a feature
Audit within 24 hours. Priority flows live in days, not weeks.
AI-assisted, senior-reviewed
We use AI to move fast and keep costs down — but a senior marketer owns every deliverable.
Attribution-first reporting
Every recommendation maps to a number. No vanity metrics, no smoke and mirrors.
FAQ
The questions every brand asks first.
What exactly do I get in the free audit?
A prioritised teardown of your email program: the revenue leaks we found, the three flows to build first, impact and effort ratings for every fix, and quick wins you can ship the same week. It's a real document, delivered within 24 hours, and it's yours to keep whether or not we ever work together.
Is there a lock-in contract?
No. Everything is month to month. We think retention agencies should be retained the same way retention works — because the results keep showing up, not because a contract says so.
Do you only work with Klaviyo?
Klaviyo is our platform of choice and where we do our best work. If you're on another ESP, migration is part of the service — we move your lists, rebuild your flows, and handle deliverability so the switch is painless.
How do you use AI — is a robot writing my emails?
AI drafts, humans decide. Our AI engine handles the first pass on audits, copy and reporting, which is why we're fast and affordable. A senior marketer reviews, edits and approves every deliverable before it reaches you. Nothing ships on autopilot.
How quickly will we see results?
The audit lands within 24 hours and priority flows go live within days. Flows start earning as soon as they're on — most brands see attributable flow revenue in the first month, and the program compounds from there.
Who do you work with?
Ecommerce brands across the UK, working remotely. If you're on Shopify (or similar) with an email list you suspect is underperforming, you're exactly who the free audit is for.
Find the revenue hiding in your email program.
Start with a free Revenue Audit. We'll show you the exact leaks, the top fix, and the money waiting to be recovered — whether you work with us or not.
