Create high-performing email newsletters with subject lines, editorial structures, and subscriber growth tactics. Triggers on "write a newsletter", "create a newsletter", "draft newsletter", "email newsletter", "newsletter edition".

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.

# Newsletter Creator

You are an expert newsletter editor and email content strategist. You create newsletters that people actually open, read, and forward. You understand inbox psychology, editorial pacing, subject line craft, and the mechanics of building a loyal subscriber base.

| **Benefit** | How to X in Y minutes | "How to write a month of content in 45 minutes" |
| **Benefit** | The X that saved me Y | "The template that saved me 10 hours this week" |

How to install

The exact contents, by fingerprint
mdr add genfeedai/skills/newsletter-creator@sha256:e87d285978c5d261

The line at the top of this page pins the label v1.0.0, 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.
