Send Listmonk Campaigns from OpenClaw

OpenClaw can create and schedule Listmonk email campaigns through the Postiz skill. You message OpenClaw with the newsletter content, and it calls the Postiz CLI to set the subject line and preview text, choose the subscriber list and template, and schedule the send, often alongside the social posts for the same announcement.

How Postiz Becomes an OpenClaw Skill

✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Run openclaw skills check to confirm the postiz binary and credentials are in place
✓Skills are loaded on-demand, keeping the agent context clean
✓Works with any LLM backend: Claude, GPT, Gemini, Llama, and more

Scheduled & Proactive

Cron jobs for recurring newsletters

OpenClaw automations run on cron expressions in an isolated session and can announce results to a chat channel. Create one that drafts and schedules your Listmonk content through Postiz, so nothing waits on a manual trigger.

openclaw automations (cron)

openclaw automations create "0 9 * * 1-5" \
  "Compile this week's published posts with postiz posts:list into a short newsletter and schedule it as a Listmonk campaign to the Subscribers list for 8am Friday." \
  --name "Listmonk daily post" \
  --session isolated \
  --announce --channel telegram \
  --to "<your chat id>"

# openclaw cron is an alias for the same command

Also Works with Claude Code

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code, which has its own guide for posting to Listmonk from Claude Code.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, 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: Done! Scheduled on Listmonk for
  tomorrow at 9:00 AM.

Listmonk + Other Platforms

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

Example

> Post "Excited to announce our new feature!" to
  Listmonk and LinkedIn tomorrow at 9am, then schedule
  a daily tip on Listmonk every weekday at 10am

OpenClaw: Done! Scheduled:
  - Listmonk + LinkedIn: tomorrow 9:00 AM
  - Daily tips on Listmonk: Mon-Fri 10:00 AM

Listmonk rules OpenClaw has to follow

Postiz enforces these Listmonk constraints when OpenClaw creates a post. Knowing them up front avoids a failed request.

✓subject, preview, and list are required. OpenClaw drafts subject and preview text if you do not provide them, but say which list to use.
✓Lists and templates are passed by ID. Ask OpenClaw to list your Listmonk lists and templates through Postiz before sending.
✓Listmonk is self-hosted. Postiz needs network access to your Listmonk instance, so connect it in Postiz first.
✓Email is hard to recall. Ask OpenClaw to create the campaign as a draft you approve before it sends.

OpenClaw and Listmonk: frequently asked questions

How do I send Listmonk campaigns from OpenClaw?

Install the Postiz skill in OpenClaw, run postiz auth:login, and connect your Listmonk instance in Postiz. Then message OpenClaw with the content, subject, preview text, list, and time. OpenClaw runs postiz posts:create with the Listmonk settings and confirms the scheduled campaign.

Can OpenClaw pick the right Listmonk list and template?

Yes. Postiz exposes your Listmonk lists and templates. OpenClaw runs postiz integrations:trigger to fetch them, matches the names you gave, and passes the IDs in the list and template settings. Ask "which lists do I have?" to see them first.

Why send email through a social media tool?

Because launches rarely stop at one channel. One request to OpenClaw can schedule the LinkedIn post, the tweet, and the Listmonk newsletter together, and Postiz shows them side by side in the calendar so your announcement lands everywhere at once.

Does OpenClaw need Listmonk API credentials?

No. Postiz holds the connection to your Listmonk instance, and OpenClaw only runs the Postiz CLI. You authenticate OpenClaw with postiz auth:login or a Postiz API key, so no Listmonk admin credentials are stored in OpenClaw. Revoke the connection from Postiz at any time.

Can OpenClaw send a weekly newsletter automatically?

Yes. Create an OpenClaw automation with a weekly cron expression and a prompt that compiles the digest and schedules the Listmonk campaign through Postiz. Ask it to create a draft and announce the preview in your chat channel so a human approves each send.
