How It Works

Find Your Listmonk Integration

List your connected accounts and grab your Listmonk integration ID. You can also fetch available settings to see what options are supported.

Discovery

# List all integrations
postiz integrations:list

# Filter for Listmonk
postiz integrations:list | jq \
  '.[] | select(.identifier=="listmonk")'

# Get Listmonk settings schema
postiz integrations:settings <listmonk-id>

Compose Your Email

Write your email body content. The content flag accepts plain text or HTML. Pair it with a subject line and preview text in the settings.

Compose

# Simple text email
postiz posts:create \
  -c "Hello subscribers! Here is your weekly update..." \
  --settings '{"subject":"Weekly Update","preview":"Big news inside","list":"list-1"}' \
  -i "listmonk-id"

# With HTML content
postiz posts:create \
  -c "<h1>Newsletter</h1><p>Content here...</p>" \
  --settings '{"subject":"March Newsletter","preview":"What happened this month","list":"list-2","template":"tmpl-1"}' \
  -i "listmonk-id"

Schedule and Send

Schedule your email campaign for a specific time or send immediately. Target a specific list and optionally apply a template for consistent formatting.

⏰

Proactive Automation

How Postiz Becomes an OpenClaw Skill

When you install Postiz Agent globally, OpenClaw automatically discovers it by reading the bundled SKILL.md file. This file tells OpenClaw what commands are available, what environment variables are needed, and how to compose Listmonk campaigns with the right settings.

✓Install from ClawHub with one command: clawhub install nevo-david/postiz
✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Eligibility is checked automatically — POSTIZ_API_KEY must be set
✓Skills are loaded on-demand, keeping the agent context clean
✓Works with any LLM backend: Claude, GPT, Gemini, Llama, and more

Install from ClawHub

# Install the Postiz skill
clawhub install nevo-david/postiz

# Or install the CLI globally
npm install -g postiz

# Set your API key
export POSTIZ_API_KEY=your_api_key

# Verify OpenClaw sees it
openclaw skills list --eligible

# Output:
# - postiz: Social media automation
#   CLI for scheduling posts
#   across 30+ platforms

Listmonk Campaigns with OpenClaw

Message OpenClaw from any platform — it reads the Postiz skill, discovers your Listmonk integration, and handles the entire email campaign workflow autonomously.

🦀

From Any Chat App

WhatsApp, Telegram, Slack, Discord...

Send a message to OpenClaw from your favorite chat app. It runs as a persistent daemon on your machine, so it picks up your message, discovers your Listmonk integration via Postiz, composes the email, and sends the campaign — all while you go about your day.

WhatsApp / Telegram

You: Send the weekly newsletter to
  list-1 with subject "March Update"

OpenClaw: Got it! Here's what I'll do:
  1. Find your Listmonk integration
  2. Compose campaign with subject
  3. Set preview text and target list-1

  Done! Your email campaign is sent.

Scheduled & Proactive

Cron jobs for recurring newsletters

OpenClaw supports cron-based heartbeat tasks. Set up a recurring job that generates newsletter content and sends it to your Listmonk lists automatically — no manual trigger needed.

openclaw.json (heartbeat)

{
  "heartbeat": [
    {
      "cron": "0 8 * * 1",
      "prompt": "Compile the latest blog
  posts from ~/content/posts into
  a weekly newsletter. Send via
  Postiz to Listmonk list-1 with
  subject 'Weekly Digest' and
  preview 'Your weekly roundup'.
  Use the newsletter-tmpl template."
    }
  ]
}

Why OpenClaw + Postiz for Listmonk

OpenClaw's skill system makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for Listmonk email workflows.

✓Message from WhatsApp to send a newsletter — no terminal needed
✓Cron jobs for hands-free weekly newsletter delivery
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Template selection applied automatically based on campaign type
✓Cross-post email content to Listmonk + social platforms in a single conversation
✓Model-agnostic — works with Claude, GPT, Gemini, or open-source LLMs

Also Works with Claude Code

Postiz Agent works as a CLI tool with any AI agent that can execute shell commands — including Anthropic's Claude Code.

Claude Code

by Anthropic

Claude reads the SKILL.md file to learn all available Postiz commands, then autonomously discovers your Listmonk integration, composes your email campaign with subject, preview text, and list targeting, and sends it on schedule.

Claude Code

> Send a newsletter to list-1 about our
  new feature launch, schedule for Monday

Claude will automatically run:
  postiz integrations:list
  postiz posts:create \
    -c "<h1>New Feature Launch</h1>..." \
    -s "2025-03-03T09:00:00Z" \
    --settings '{"subject":
      "Exciting New Feature",
      "preview":"Check out what we built",
      "list":"list-1",
      "template":"newsletter-tmpl"}' \
    -i "listmonk-id"

Listmonk + Other Platforms

Send an email campaign and post to social media simultaneously. Each platform gets its own settings.

Terminal

# Send email and post to social media simultaneously
postiz posts:create \
  -c "We just launched our new feature! Check it out." \
  -s "2025-03-01T09:00:00Z" \
  --settings '{"subject":"New Feature Launch","preview":"Something big is here","list":"list-1"}' \
  -i "listmonk-id,twitter-id,linkedin-id"

# Batch schedule a month of newsletters
for week in 1 2 3 4; do
  postiz posts:create \
    -c "Week $week newsletter content..." \
    -s "2025-03-0${week}T08:00:00Z" \
    --settings '{"subject":"Weekly Digest - Week '$week'","preview":"Your weekly roundup","list":"list-1","template":"newsletter-tmpl"}' \
