## What it does

The skill covers newsletter formats and cadence, topic planning, and email structure. It offers frameworks for balancing educational, product, and promotional material, testing subject lines, and choosing how to show code in an email. It also outlines ways to attract subscribers through a blog, documentation, or other channels.

Start by loading audience details from `.agents/developer-audience-context.md`, including readers’ roles, interests, other content sources, and preferred tone. If that file is missing, run `developer-audience-context` first. Without this context, the advice cannot reflect the audience’s stack and interests.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill developer-newsletter -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/developer-newsletter/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/developer-newsletter/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill developer-newsletter -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill developer-newsletter -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/developer-newsletter/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill developer-newsletter -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/jonathimer/devmarketing-skills/tree/HEAD/skills/developer-newsletter/SKILL.md

## When to use it
- choose a newsletter format and publishing cadence
- plan topics for upcoming issues
- structure an email for developer readers
- prepare subject line variants for an A/B test
- find channels for newsletter growth

## Example prompts
- Use `.agents/developer-audience-context.md` to suggest a newsletter format and cadence for developer readers.
- Draft an issue with a short opening, clear sections, and a links block.
- Suggest subject line variants and an A/B testing plan for the next issue.

# Developer Newsletter

This skill helps you build and write newsletters that developers actually open, read, and look forward to receiving. Covers content strategy, writing, growth, and deliverability.

---

## Before You Start

**Load your audience context first.** Read `.agents/developer-audience-context.md` to understand:

- Who you're writing for (role, seniority, tech stack)
- What content resonates (problems, interests)
- Where else they consume content (to avoid duplicate effort)
- Voice & tone (how casual/technical)

If the context file doesn't exist, run the `developer-audience-context` skill first.

## Newsletter Strategy

### Define Your Newsletter Type

| Type | Description | Example |
|------|-------------|---------|
| **Product updates** | Changelog, new features, tips | Vercel's updates |
| **Curated links** | Best content from around the web | TLDR, Bytes |
| **Original content** | Your own articles, tutorials | Cassidy Williams |
| **Community digest** | What happened in your community | Dev community roundups |
| **Educational series** | Teaching a topic over time | Course-style newsletters |

**Best practice**: Pick ONE primary type. You can mix in others, but have a clear identity.

### Frequency Matrix

| Frequency | Best For | Risk |
|-----------|----------|------|
| **Daily** | Curated links, news | Fatigue, hard to maintain |
| **Weekly** | Most newsletters | Sweet spot for most |
| **Bi-weekly** | Original content heavy | Can lose momentum |
| **Monthly** | Product updates, digests | Easy to forget you exist |

**Developer preference**: Weekly is the sweet spot. Developers are busy and inbox-protective.

## Content Mix Framework

### The 70-20-10 Rule

| Percentage | Content Type | Purpose |
|------------|--------------|---------|
| **70%** | Value content | Teach, inform, help |
| **20%** | Product content | Updates, features, how-tos |
| **10%** | Promotional | CTAs, asks, sales |

### Content Categories

Build a rotation of these:

| Category | Examples |
|----------|----------|
| **Tutorials** | "How to implement X" |
| **News analysis** | "What Y announcement means for you" |
| **Tool/library roundups** | "5 libraries for handling Z" |
| **Code snippets** | "Quick tip: better error handling" |
| **Community highlights** | "Best from our Discord this week" |
| **Industry takes** | "Why I think X is overhyped" |
| **Behind the scenes** | "How we built feature Y" |
| **Q&A** | "You asked, we answered" |

## Writing Developer Emails

### Subject Line Framework

What works for developers:
```
END THIRD-PARTY FILE f76aafe2813899b9

The third-party file has ended. Everything between the f76aafe2813899b9 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
