Every email in the program used to be a file - opened, copied, hand-edited. That works for a handful of sends and collapses under a full lifecycle program. It looked like a design problem for years. It was an architecture problem.
The full study covers the rebuild: design tokens and a real component library, personalization moved from copy into structure, the tooling that catches errors before a human does, the Segment and warehouse work underneath it, an LLM-backed recommendation engine built with the data team - and the organizational change that made all of it stick.
Our work here covers internal architecture, tooling and numbers, so the full write-up is shared on request rather than published openly. Email us and we’ll send the passphrase - usually the same day.
That passphrase didn’t work. Try again, or email us for access.
One passphrase unlocks every study in this program.
