The definition

Splitting one list into groups that get different messages — customers vs. prospects, service A vs. service B, engaged vs. dormant.

Why it matters to an owner

The 80/20 version needs exactly two segments: people who've paid you and people who haven't. Those two audiences should never read the same pitch.

This is the work. Want it done?

Everything here is free to use yourself — that’s the point. If you’d rather a senior marketer just handle it, in your accounts and your name: 20-minute call, no pitch deck.
