Quick start

Run the postqueen CLI directly, or add the MCP endpoint to your Gemini CLI settings and ask for Listmonk campaigns in plain language.

MCP supported
Terminal or settings.json
npm install -g postqueen
export POSTQUEEN_API_KEY=your_api_key
 
# Or MCP, in your Gemini CLI settings:
# { "mcpServers": { "postqueen": {
#     "url": "https://api.postqueen.ai/mcp/KEY"
# } } }

What Gemini CLI can run on Listmonk

Listmonk commands it can verify

Gemini CLI runs postqueen and reads the JSON back, so it can confirm which Listmonk campaigns exist and at what times instead of reporting success it did not check.

Windows that fit Listmonk

Tell Gemini CLI when your lists are busiest and it schedules campaigns into that window on Listmonk, day after day, without reminders.

Whole campaigns, scheduled

Gemini CLI drafts the campaign and postqueen delivers it to your Listmonk lists, so subscribers hear from you on a schedule you set once.

Drafts until you are ready

Ask Gemini CLI for drafts only. They sit on the postqueen calendar unscheduled, so you can edit them and pick the time yourself, and nothing reaches your subscribers on Listmonk until you do.

Three steps to a full queue

Step 1

Discover Listmonk

Gemini CLI calls postqueen to list your connected lists and sees what Listmonk supports, so drafts start from real capabilities, not guesses.

Step 2

Draft with Gemini CLI

Give it the brief. The agent writes Listmonk-shaped campaigns and proposes publish times that match when your subscribers are around.

Step 3

Check and publish

Look over the queue on the postqueen calendar and change anything you want. postqueen publishes each post at its time, and Gemini CLI can pull the results after.

What Listmonk allows

Gemini CLI reads these limits from postqueen before it composes, so a draft that would be rejected never reaches the queue.

Frequently asked questions

How does Gemini CLI connect Listmonk to postqueen?

Over MCP, registered once in Gemini CLI's own config so the Listmonk tools are there in every session. It also runs commands, so the CLI covers the same Listmonk campaigns when you would rather script them; both use the same API key.

Can Gemini CLI schedule Listmonk campaigns at exact times?

Yes. Give it exact slots or a rule like mornings at nine and it sets publish times on the campaigns it creates, keeping your lists active on a steady rhythm.

Will Gemini CLI publish to Listmonk on its own?

Only if you ask it to. Tell it to save drafts and nothing is scheduled: the campaigns wait on the calendar until you set a time. Tell it to schedule, and they go out at the times you can see, which is the setup most people move to once they trust the output.

Can one brief cover Listmonk and other channels too?

Yes. postqueen connects 30 channels, so Gemini CLI can turn the same brief into Listmonk campaigns plus adapted versions for every other channel you run.

Does Gemini CLI access cost extra on postqueen?

No. The agent uses your regular API key and plan limits: unlimited posts on every plan, and channel counts from 5 on Creator up to uncapped on Ultimate.

Can I try Listmonk scheduling for free?

Yes. Listmonk itself is free and open source, and every postqueen cloud plan starts with a 7-day free trial, cancel anytime. If you want the whole stack under your control, self-hosting postqueen is free too, so the entire newsletter pipeline can run on your own machines.

What do I need to connect Listmonk to postqueen?

A running Listmonk instance that postqueen can reach over HTTPS, plus API credentials created in your Listmonk admin settings. Once connected, postqueen creates campaigns through the official API and your instance handles delivery through the SMTP servers you configured.
