Myth: Deterministic identity resolution is always worth chasing
The ideal everyone sells: stitch every touchpoint to one perfect person. The correction: chasing 100% deterministic match across anonymous, logged-out, cross-device traffic burns quarters for marginal lift — household or probabilistic good-enough often clears the bar.
— A thread on the diminishing returns curve of identity match rates.
— A piece on identity resolution tradeoffs — accuracy vs. coverage vs. cost.
— A teardown of a match-rate project that never paid back its build.
— A checklist for the use cases that genuinely need deterministic.
Skip if you run regulated, high-value 1:1 journeys. Essential before you fund a year of identity-stitching work.
That's the stack for this week. Forward to a teammate.
