# Newsletter publishing
Practical workflows for building and managing email newsletters for journalism and academia.

## Newsletter architecture
### Content strategy framework
```markdown
## Newsletter strategy document
### Core identity
- **Name**:
- **Tagline** (one line):
- **What readers get**: [specific value proposition]
- **Frequency**: [ ] Daily [ ] Weekly [ ] Bi-weekly [ ] Monthly
### Target audience
- Primary reader:
- What they care about:
- Why they'll subscribe:
- What they'll do with this info:
### Content pillars
1. [Core topic 1] - [how often]
2. [Core topic 2] - [how often]
3. [Recurring feature] - [how often]
### Voice and tone
- Formal ↔ Conversational: [1-5]
- Serious ↔ Light: [1-5]
- Reported ↔ Personal: [1-5]
### Success metrics (first 6 months)
- Subscriber goal:
- Target open rate:
- Target click rate:
```
### Issue structure template
```markdown
## [Newsletter Name] - Issue #[XX]
**Date**: [Date]
**Subject line**: [Subject]
**Preview text**: [First 50-90 characters readers see]
---
### Opening hook
[2-3 sentences that make readers want to keep reading]
### Main story
[Your primary content - 300-600 words for most newsletters]
### Secondary items (if applicable)
- **Quick hit 1**: [Brief item with link]
- **Quick hit 2**: [Brief item with link]
### Recurring section
[Weekly column, data point, recommendation, etc.]
### Sign-off
[Personal note, call to action, or preview of next issue]
---
**Unsubscribe** | **Preferences** | **Forward to a friend**
```
## Technical implementation
### HTML email template (responsive)
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>{{newsletter_name}}</title>
<style>
/* Reset styles for email clients */
body { margin: 0; padding: 0; width: 100%; }
table { border-collapse: collapse; }
img { border: 0; display: block; }
/* Responsive container */
.container {
max-width: 600px;
margin: 0 auto;
font-family: Georgia, serif;
font-size: 18px;
line-height: 1.6;
color: #333;
}
/* Dark mode support */
@media (prefers-color-scheme: dark) {
.container { background-color: #1a1a1a; color: #e0e0e0; }
a { color: #6db3f2; }
}
/* Mobile styles */
@media only screen and (max-width: 480px) {
.container { padding: 15px !important; }
h1 { font-size: 24px !important; }
}
</style>
</head>
<body>
<table role="presentation" width="100%">

def add_subscriber(self, email: str, name: str = None,
tags: List[str] = None) -> SubscriberWeb accessibility patterns for news sites, journalism tools, and academic platforms. Use when building accessible interfaces, auditing existing sites for WCAG compliance, writing alt text for news images, creating accessible data visualizations, or ensuring content reaches all readers including those using assistive technologies. Essential for newsroom developers and anyone publishing web content.
Electron desktop application development with React, TypeScript, and Vite. Use when building desktop apps, implementing IPC communication, managing windows/tray, handling PTY terminals, integrating WebRTC/audio, or packaging with electron-builder. Covers patterns from AudioBash, Yap, and Pisscord projects.
Remote JavaScript console access and debugging on mobile devices. Use when debugging web pages on phones/tablets, accessing console errors without desktop DevTools, testing responsive designs on real devices, or diagnosing mobile-specific issues. Covers Eruda, vConsole, Chrome/Safari remote debugging, and cloud testing platforms.
Use this skill when creating new files that represent architectural decisions — data models, infrastructure configs, auth boundaries, API contracts, CI/CD pipelines, or event systems. Flags irreversible decisions and forces a discussion about trade-offs before committing.
Python data processing pipelines with modular architecture. Use when building content processing workflows, implementing dispatcher patterns, integrating Google Sheets/Drive APIs, or creating batch processing systems. Covers patterns from rosen-scraper, image-analyzer, and social-scraper projects.
This skill should be used when the user reports a bug, describes unexpected behavior, says something is "broken", "not working", "failing", mentions an "error", "issue", or "problem" in code, or asks to "fix" something. Enforces test-driven bug fixing workflow.
Methodology for effective AI-assisted software development. Use when helping users build software with AI coding assistants, debugging AI-generated code, planning features for AI implementation, managing version control in AI workflows, or when users mention "vibe coding," Claude Code, Cursor, GitHub Copilot, Aider, Continue, Cline, Codex, Windsurf, or similar AI coding tools. Provides strategies for planning, testing, debugging, and iterating on code written with LLM assistance.
Web scraping with anti-bot bypass, content extraction, undocumented APIs and poison pill detection. Use when extracting content from websites, handling paywalls, implementing scraping cascades or processing social media. Covers requests, trafilatura, Playwright with stealth mode, yt-dlp and instaloader patterns.
