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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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segments (new, active, lapsed, win-back), and a suppression list (unsubscribed, hard-bounced, spam-complained, consent-withdrawn).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]
```

How to install

The exact contents, by fingerprint
mdr add aaron-he-zhu/aaron-marketing-skills/list-segment-builder@sha256:39565d9fbb0223ee

The line at the top of this page pins the label v20.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
