A newsletter people open: positioning, format, sections, cadence and growth, fed by the posts Maggie publishes. Use when the user says things like "start a newsletter for our customers"; "turn our blog posts into a monthly email"; "what should go in our newsletter?"; "nobody opens our newsletter anymore"; "write this week's newsletter issue"; "how often should we send a newsletter?". Works with the CMO.so MCP server (cmo-so plugin).
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.

With CMO.so connected, the articles Maggie publishes on the website become the steady supply of material, so each issue sends readers back to the site and the newsletter costs little extra effort. ## When to use - Starting a newsletter, rescuing one with falling clicks, or turning a blog into a regular email. - Writing a specific issue from recent posts, news or product updates. - Choosing cadence, sections, a name or a growth plan for the list. - Not for: automated sequences triggered by a signup or behaviour (use `cmo-email-sequences`), outreach to people who never opted in (use `cmo-cold-email`), win-back and failed-payment emails (use `cmo-churn-prevention`). ## Before you start …

How to install
mdr add ai-marketing-os-ltd/cmo-so-skills/cmo-newsletter@sha256:b25f2b0251ff0511The line at the top of this page pins the label v0.15.0, 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.
