The reference case for every Optin engagement is below. More client cases are still in flight. As they close their first quarters, this is where they'll live.
01Anchor case
M&A operator audience · Selective Distribution™
Walker Deibel — operator, M&A advisor, founder of Wealth Stack Weekly — built a 300K+ ICP newsletter from zero on Optin's Selective Distribution infrastructure. Open rate reported with Apple-MPP / prefetch inflation in mind — not our core metric. The audience is the moat every Optin engagement is built on.
The case proves the engine: verified ICP at scale, in an owned file, with no paid spend. The math holds across deal size and vertical.
Founders, search funds, micro-PE, and small-cap M&A advisors — the operator class buying and building businesses under $50M EV.
Placement-driven acquisition across our proprietary domain pool. Engagement-filtered weekly. Migrated to Walker's ESP under his brand.
Editorial discipline maintained through the ramp. Open rate did not degrade as the audience scaled — engagement filter held the line.
The audience lives in Walker's ESP, under his domain, under his brand. The compounding continues without Optin in the loop.
