list-segment-builder

Use when the user asks to "build email segments from my list", "make engaged / lapsed / RFM segments", "set up cart-abandoner or lifecycle-stage audiences", or "build a suppression list of unsubscribes and bounces"; turns the user''s OWN list/CRM/GA4/ecommerce export into behavioral, attribute, and lifecycle-stage segments plus a suppression list, with per-segment sizes labeled Measured/Estimated, informing the SEND E (Engagement/targeting) dimension. Not for scoring EQS or running vetoes — use email-quality-auditor; not for authentication or spam-content checks — use deliverability-qa. 邮件列表分群

# List Segment Builder Turns the user's own list/CRM/GA4/ecommerce export into behavioral segments (engaged-90d, cart-abandoners), attribute and RFM tiers, lifecycle-stage segments (new, active, lapsed, win-back), and a suppression list (unsubscribed, hard-bounced, spam-complained, consent-withdrawn). It defines **who each segment is and who must never be mailed** — email-creative-builder and email-sequence-designer then compose for those segments; this skill does not send, design flows, or score the program. ## Quick Start ``` Build email segments from my list export: [path]. Goal is retention. ESP export attached. ``` ``` Make engaged-90d, lapsed, and cart-abandoner segments from my ecommerce + ESP export, and give me the suppression list. [CSV] ``` ``` Map my list to RFM tiers and lifecycle stages so I can reuse the same audiences across every campaign. [CRM export] ``` ## Skill Contract **Expected output**: a **segment map** in four buckets — (1) **behavioral segments** grouped by activity (opened/clicked recency, cart-abandon, browse-abandon), (2) **attribute + RFM tiers** (recency/frequency/monetary from the user's own order data), (3) **lifecycle-stage segments** (new → acti

How do I install it?

Run `npx skills add aaron-he-zhu/aaron-marketing-skills --skill list-segment-builder --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From aaron-he-zhu/aaron-marketing-skills, a repository with 2,508 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
