    Systems & Operations

    Marc spent nearly two decades building systems in IT before he opened a Klaviyo account. It shows in what he asks first, which is how a thing is wired rather than what it says. Most brands run email on instinct. A Tuesday newsletter, a discount code, hope. He builds the opposite: flows you can open up and inspect, segmentation and suppression logic that holds, deliverability groundwork nobody notices until it fails, attribution clean enough that nobody has to squint at a dashboard. He also runs the rhythm behind every Flowbutler account, the frameworks, the QA, the reason work lands when it is meant to and nothing goes out half checked. He is slow about the parts most agencies rush. That is generally why the numbers move at all.

    Strategy & Design

    Sue is an award-winning interior designer and a Dulux Colour Awards finalist, and she thinks about email the way she thinks about a room. Someone moves through it, and how they feel on the way is the whole point. She decides what a brand says, in what order and to whom, then makes it look like the brand instead of a template with a logo dropped in. She also runs the numbers, which is a rarer pairing than it sounds. Most email underperforms because the thinking behind it was thin, not because the send was late. Sue starts at the thinking.

What we believe

The principles behind the results.

  • An extension of your team

    Boutique on purpose. No account layers, no juniors learning on your account — the people who scope the work are the people who build it, and they have been doing it long enough to know what breaks.

  • Systems where systems belong

    Retention is high-volume work, so the checking is automated and the execution is humans and AI together. Strategy stays human, because that is a conversation. The point of the machinery is protecting the asset you own.

  • Design and commercial, not one or the other

    An email has to look like your brand and it has to do a job. Pretty that does not sell is decoration. We are interested in what the business made, not in which dashboard claims the credit.
