Guidance on maintaining a healthy email list, including re-engagement and sunset practices — trigger when a user asks about list cleaning, inactive subscribers, or email deliverability.
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.

All practices are sourced exclusively from Exit Five podcast guests and reflect their direct experience and recommendations. ## Re-Engagement Before Removal Before removing inactive subscribers, run a re-engagement campaign first. Invite inactive contacts to opt back in or confirm their continued interest. Only after this attempt — and only for contacts who remain unresponsive — should you proceed with removal. Treat the sunset policy as the final step in a sequence, not the starting point.

This skill cannot provide guidance on those specifics. Treat this as a directional principle, not an executable workflow, until more sourced detail is… …

How to install
mdr add the-nam-shub/e5-real-skills/email-list-hygiene@sha256:2aafa90ae8d71f4fThe line at the top of this page pins the label v2026-04-21, 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.
