<b>One genuine personalized line lifts reply rate from 6.2% to 14.8% — three lines adds nothing</b>

Across 88,000 outreach emails (7-month window, A/B tracked):

— Zero personalization: 6.2% reply
— One specific, relevant opener: 14.8%
— Two-to-three personalized lines: 15.3%

The jump from zero to one personalized line is the entire effect — a 2.4x lift. Adding more personalization barely moves the needle (+0.5pp) while roughly tripling research time per prospect.

What it means: heavy 'deep personalization' is a labor sink past the first relevant sentence.

<b>Write one specific, true line per prospect, then send — don't gold-plate.</b>
