Post to Listmonk from Grok Bot

Grok Bot can send email campaigns through Listmonk using the Postiz plugin. Add the plugin to a Bot, store your Postiz API key as a secret, and describe the newsletter. The Bot writes the subject and preview text, picks the mailing list and template, schedules the send in Postiz, and can run a weekly newsletter routine from its cloud computer.

What is Grok Bot?

Grok Bot is the always-on AI teammate product from xAI and Cursor. You create named Bots, give each one a job, and they work 24/7 on their own persistent cloud computer — with a browser, a filesystem, and a terminal — pinging you only when they need approval.

Grok Bot is not the Grok chatbot. Grok is the assistant you chat with on X and grok.com. Grok Bot is a separate app for delegating real, multi-step work — like running your Listmonk presence with Postiz.

💻

Own Cloud Computer

Every Bot gets a persistent cloud machine with a terminal. Postiz runs there, so your Listmonk posts go out even when your laptop is closed.

🔁

Routines

Turn any task into a routine that runs on a schedule. Your Bot drafts, schedules, and reports on Listmonk content without being asked twice.

🛡️

Approvals Built In

Bots ask before changing external systems. Review the Listmonk posts your Bot prepared in Postiz, approve, and it publishes.

How Postiz Works with Grok Bot

Postiz is listed on the Grok Bot plugin marketplace. Add it to a Bot and the Postiz skill, CLI, and command reference are installed on its cloud computer — the Bot can then manage your Listmonk workflow on its own.

✓Type /add-plugin postiz in a Bot chat, or add it from the Plugins sidebar
✓Store your POSTIZ_API_KEY as a Bot secret when prompted
✓The Bot reads the bundled SKILL.md and learns every Postiz command
✓Works in every Bot on your shared workspace, on desktop and iPhone
✓Approvals keep a human in the loop before anything is published

Grok Bot

# 1. Add the plugin to your Bot
/add-plugin postiz

# 2. Store your Postiz API key
#    as a secret when prompted

# 3. Ask your Bot to verify
You: Find my Listmonk channel in Postiz

Bot: Running postiz integrations:list
  Found your Listmonk integration.
  All Postiz commands are ready.

How Grok Bot runs Listmonk on a routine

Your Bot reads the Postiz skill, discovers your Listmonk integration, and handles the entire posting workflow — from content creation to scheduling — on its own cloud computer.

🧠

Message Your Bot

Desktop, iPhone, or a group chat

Send a message to your Bot from the desktop app or your iPhone. It runs on its own cloud computer, so it picks up your message, discovers your Listmonk account via Postiz, uploads your media, and schedules the post — then asks you to approve before it goes live.

Grok Bot

You: Post to Listmonk about our new
  feature launch, schedule for tomorrow
  at 9am

Bot: Got it! Here's the plan:
  1. Find your Listmonk integration
  2. Compose your post content
  3. Schedule for tomorrow 9:00 AM

  Done! Post scheduled successfully.
  Post ID: abc-123

🧠

Routines

Recurring work on a schedule

Save the task as a routine. Your Bot runs it on a schedule from the cloud, checks for new content, and posts it to Listmonk automatically — no manual trigger needed.

Grok Bot routine

Routine: daily-listmonk-posts
Schedule: Weekdays at 9:00 AM

Instructions:

  computer for new .txt files. For

  and send me a summary.

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. See the Claude Code guide for Listmonk, the guide for any AI agent, or connect over the Postiz MCP server.

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.

Cross-post Listmonk content to 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

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

Listmonk rules Grok Bot follows

Grok Bot reads the Listmonk rules from postiz integrations:settings before scheduling. These are the ones that most often change what gets published.

✓subject, preview, and list are all required. Grok Bot writes the subject and preview text if you do not, and resolves the list ID with postiz integrations:settings.
✓template is optional and takes a Listmonk template ID. Without it Listmonk uses your default template.
✓Listmonk sends to real subscribers, so always review the draft before approving. Sending cannot be undone.
✓Postiz connects to your own Listmonk instance. Connect it in Postiz before asking the Bot.

Grok Bot and Listmonk: frequently asked questions

How do I send a Listmonk campaign from Grok Bot?

Add the Postiz plugin with /add-plugin postiz and store your POSTIZ_API_KEY as a Bot secret. Connect Listmonk in Postiz, then describe the newsletter. The Bot sets subject, preview text, list, and template, and schedules the send through Postiz. You approve before anything is sent.

How does Grok Bot choose the Listmonk list and template?

It runs postiz integrations:settings for your Listmonk channel, which returns your lists and templates with their IDs. Name the list and template in plain language and the Bot maps them to IDs. If a name is ambiguous, it asks before scheduling.

Can Grok Bot write the subject line and preview text?

Yes. Both are required by Listmonk, so if you do not provide them the Bot drafts a subject and a short preview from the newsletter body and shows them to you for approval. You can ask for alternatives before it schedules the campaign.

Is it safe to let Grok Bot send email campaigns?

Grok Bot asks for approval before it changes external systems, and Postiz shows the campaign in your calendar before send time. Review the draft, list, and schedule before approving, because a sent campaign cannot be recalled. Keep a human in the loop for every send.

Can Grok Bot run a weekly newsletter routine?

Yes. Save a routine that drafts the newsletter from a file on the Bot's cloud computer every Friday, resolves the list and template, and sends the draft to you for approval. After you approve, the Bot schedules the send through Postiz.
