# Bulk Sender Lint - the Gmail, Yahoo and Outlook.com rules, checked in your mailer code

> Runs the same checker as the npm package `@readystack/bulk-sender-lint` on a Node.js runtime that pip installs for you (`nodejs-wheel-binaries`) - no system Node.js needed. Your files are checked locally.

21 dated checks over SPF, DKIM, DMARC, RFC 8058 one-click unsubscribe and TLS, in VS Code and in the browser

## Install

```
bulk-sender-lint file
```

Node 18+. The same 21 rules as the VS Code extension, from a terminal or CI.

## Free

- Check the file you have open - all 21 checks, every finding with the clause it comes from, the date it took effect and the line
- `--rules` lists every rule

## With a licence ($29 once)

- Sweep every matching file in the workspace and write a dated evidence report you keep, for a deliverability review or a client handover

```
@readystack/bulk-sender-lint --dir ./templates --report html --out report.html
```

A deliverability consultant bills $150 to $250 an hour

## Use from an AI agent (MCP)

Claude Code · Cursor · Windsurf · any MCP client - add to your MCP config:

```json
{ "mcpServers": { "bulk-sender-lint": { "command": "npx", "args": ["-y", "@readystack/bulk-sender-lint", "--mcp"] } } }
```

Tools: `check_text` and `check_file` (free) · `check_dir` (licence). The agent gets every finding with the line number.

## Use in CI

```yaml
- name: Bulk Sender Lint - the Gmail, Yahoo and Outlook.com rules, checked in your mailer code
  run: npx -y @readystack/bulk-sender-lint --dir . --ci
```

(container: `docker run --rm -v "$PWD:/work" getreadystack/bulk-sender-lint --dir /work --ci`)

The folder sweep, reports and CI mode need one licence — one payment, no subscription. Set `READYSTACK_LICENSE=<key>` or run `--license <key>` once.
