Measurement over opinion.

I've spent 11+ years in conversion optimization and e-commerce email across European brands. Built and ran email programs for supplement companies, coffee roasters, cosmetics labels, pet food shops. After the tenth audit I saw the same pattern everywhere: flows firing on calendars, customers buying in cycles, and nobody measuring the gap between them.

clv.marketing exists to make that gap visible — as a number, from real order data, before anyone spends a dollar fixing it. German engineering mindset: reconcile, validate, then conclude. If there's no leak, the report says so and you keep your money.

The programs behind this method ran at real scale — including a hardware brand whose email channel we built from zero to six figures a month, tracked with our own attribution discipline instead of platform defaults. At that volume, guessing gets expensive fast.

We don't write think pieces — we publish what we measure.
