Drafts and designs a complete HTML email newsletter from a topic or content brief. Outputs paste-ready HTML for Loops, Mailchimp, Beehiiv, Resend, or any standard email platform. Includes subject line options and plain-text fallback. Trigger when a user says "write a newsletter", "draft an email newsletter", "create an HTML email", "design an email for my subscribers", or "write a newsletter about [topic]".
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 Newsletter Draft and design a complete HTML email newsletter from a topic or content brief. Output is paste-ready for Loops, Mailchimp, Beehiiv, Resend, or any standard email platform. --- **Critical rule:** Table-based HTML with inline styles only. No CSS classes, no flexbox, no grid, no `<style>` blocks. Every element gets `style=""` directly. This is not optional -- email clients strip everything else. --- ## Step 1: Brief Intake Need three things to start. If all three present in the message: skip to Step 2. If any missing, ask exactly: > "To get started, I need three things: > 1. **Topic** -- what is this newsletter about? > 2. **Audience** -- who is reading? (role, company size, how they know you) > 3. **Primary CTA** -- what one action do you want readers to take?" Wait for all three before continuing. --- ## Step 2: Complete Intake Ask all questions in one message, grouped by category. User can skip any -- defaults apply. > "A few questions before I draft -- answer what you know, skip the rest: > > **Content** > 1. **Length** -- brief (300 words, punchy) / standard (500-700) / deep dive (800+ words)? …

How to install
mdr add varnan-tech/opendirectory/email-newsletter@sha256:84ecf39902a982b7The 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.
