+# developer-newsletter
+
+**Build newsletters developers actually open.**
+
+## What It Does
+
+Guides you through creating and growing a developer newsletter. Covers content strategy, writing, subject lines, growth tactics, and avoiding spam filters.
+
+## When to Use
+
+- Starting a developer newsletter
+- Writing your next issue
+- Improving open/click rates
+- Growing your subscriber base
+- When you say "newsletter," "email marketing," "dev newsletter," or "email list"
+
+## Quick Start
+
+```
+/developer-newsletter
+
+I want to start a weekly newsletter about JavaScript performance.
+Target: frontend developers at mid to senior level.
+```
+
+The skill will:
+1. Load your developer audience context
+2. Help define your newsletter type and frequency
+3. Guide content mix and structure
+4. Optimize subject lines and deliverability
+
+## Key Frameworks
+
+### Content Mix (70-20-10)
+
+| Percentage | Content Type |
+|------------|--------------|
+| 70% | Value content (teach, inform, help) |
+| 20% | Product content (updates, features) |
+| 10% | Promotional (CTAs, asks) |
+
+### Subject Line Patterns
+
+What works:
+- Specific benefit: "Cut your build time by 40%"
+- Technical curiosity: "The JavaScript feature nobody uses"
+- Direct announcement: "v2.0 is here: async/await support"
+- Number + topic: "7 TypeScript tricks senior devs use"
+
+### Benchmarks
+
+| Metric | Target |
+|--------|--------|
+| Open rate | 30-50% |
+| Click rate | 5-15% |
+| Unsubscribe rate | <0.5% |
