How It Works

Find Your Listmonk Integration

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

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.

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

  --settings '{"subject":"March Newsletter","preview":"What happened this month","list":"list-2","template":"tmpl-1"}' \
  -i "listmonk-id"

✓nanoclaw reads the SKILL.md and learns all Postiz commands
✓POSTIZ_API_KEY must be set in environment
✓Skills are loaded on-demand, keeping the agent context clean
✓Runs on Anthropic's Agents SDK for reliable execution

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"

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"}' \
