Physical mail still cuts through when done with intention, but most small teams treat it as expensive noise. This episode builds the Direct‑Mail Micro‑Sprint: a privacy‑first, AI‑assisted routine to design one high-impact mailpiece, target a tiny, consented list, and measure conversion with simple QR/SMS anchors so you can prove lift on a single run. Lyric opens with a founder vignette where a well-timed postcard reactivated lapsed customers and the creative beat that made it feel personal. Nova defines minimal targeting signals and consent rules so lists stay privacy-light. Stryker diagrams a scrappy engineering stack: short URL QR codes, SMS capture fallbacks, ephemeral tracking tokens, and safe image/text enhancement. Pulse closes with a 21‑day pilot (print cap, response windows, KPIs) and three immediate plays listeners can run this week.
