Guides Claude to help B2B marketers build, maintain, and activate segmented email lists — covering exclusion logic, engagement monitoring, personalization, and list hygiene. Trigger when a user asks about segmenting email audiences, managing list health, or improving email relevance.
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
# Email List Segmentation ## Overview This skill covers B2B email list segmentation practices: how to structure segments, maintain list health, personalize sends, and avoid common over-inclusion mistakes. All practices are sourced exclusively from Exit Five podcast guests across 4 episodes. No general marketing knowledge has been added — gaps in coverage are intentional. --- ## Building Your Segmentation Logic ### Start with Exclusions, Not Inclusions When planning any email send, begin by identifying who should be excluded before deciding who to include. Ask explicitly: Should we exclude contacts who recently had a positive sales conversation? Should we exclude anyone who just filed a support ticket with a product complaint? This exclusion-first approach reduces over-inclusion, improves relevance, and produces cleaner segmentation without requiring complex inclusion logic.

How to install
mdr add the-nam-shub/e5-real-skills/email-list-segmentation@sha256:eaf9ad89aa1924c7The line at the top of this page pins the label v2026-04-20, 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.
