A newsletter format you can fill in under an hour, every issue.
A fixed template for a recurring newsletter, then one finished issue written into it from your raw material.
Newsletters rarely stop for lack of ideas. They stop because every issue starts from a blank page, takes four hours, and slips past its send date until readers stop expecting it.
Email Newsletter fixes the shape once: opener, one main piece, one short item, one ask. Each issue becomes assembly. You get a drafted issue, three subject line options, and a final trim so it reads in a few minutes.
What it produces.
- →A saved template with the slots and word counts for each part
- →One finished issue built around a single idea
- →Three subject lines with preview text
- →A one-sentence closing ask that takes one line to answer
- ✦Solo operators who send a newsletter and dread the writing
- ✦Community managers keeping a weekly or fortnightly rhythm
- ✦Small teams restarting a newsletter after a long gap

Before you buy.
How is this different from just asking Claude directly?
Asked cold, Claude writes a newsletter that sounds fine and looks different each time. This locks a format first, so you recognize your own issue, limits each one to a single idea, and checks read time and repeated points before you send.
How is this different from a Tool?
Playbooks are systematically produced to a fixed template and priced accordingly ($12.99). Tools are hand-built, one at a time, and go deeper ($39 to $199). A Playbook gives you a reliable method for routine work; a Tool is for when the judgment matters more than the format.
Will this work with ChatGPT, Gemini, and other LLMs?
Yes. You get a native Claude Skill (.zip) that auto-invokes in Claude, plus a plain .md you can paste into a ChatGPT Custom GPT, a Gemini system prompt, or any LLM. The procedure travels with the file.
Can I share this with my team?
It's licensed for your own personal and professional use. The output it produces is yours to circulate. To put the Playbook itself in the hands of a whole team, email hello@authority.md about team licensing.
What if it doesn't work for me?
If the file hasn't been delivered, or arrives defective or empty, we refund in full: see our refund policy.
