## Description

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/生命周期分群/抑制名单/流失召回

# 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segments (new, active, lapsed, win-back), and a suppression list (unsubscribed, hard-bounced, spam-complained, consent-withdrawn).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 → active → at-risk → lapsed → win-back), and (4) a **suppression list** (unsubscribed, hard-bounced, spam-complained, consent-withdrawn), each segment named with a size labeled **Measured** (counted from an exported column) or **Estimated** (inferred, method stated), informing the SEND **E (Engagement/targeting)** dimension, plus the standard handoff summary.
