Automate Listmonk with Hermes

Hand Hermes one brief and it plans the whole week: drafting Listmonk campaigns, scheduling them at the right times and reporting back when the queue is full.

Quick start

Install the CLI where Hermes executes commands, then hand over the Listmonk plan in plain language.

Terminal
npm install -g postqueen
export POSTQUEEN_API_KEY=your_api_key
 
# A task for Hermes:
# "Plan next week on Listmonk: draft five
# campaigns, schedule them and list
# what you queued"

What Hermes can run on Listmonk

One brief, a full Listmonk plan

Hermes breaks a goal into steps on its own: draft the campaigns, upload media, schedule each one and report back with what it queued for Listmonk.

Windows that fit Listmonk

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

Whole campaigns, scheduled

Hermes 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 Hermes 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

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

Step 2

Draft with Hermes

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 Hermes can pull the results after.

What Listmonk allows

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

Frequently asked questions

How does Hermes connect Listmonk to postqueen?

Install the postqueen CLI where Hermes runs commands and export your API key. Every command returns JSON, so the agent can create, schedule and list Listmonk campaigns reliably.

Can Hermes 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 Hermes 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 Hermes can turn the same brief into Listmonk campaigns plus adapted versions for every other channel you run.

Does Hermes 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.

What formats do Listmonk campaigns support?

Campaigns can be rich HTML, Markdown or plain text, and they run through Listmonk's template system, so personalization variables like the subscriber's name keep working. Draft the body in postqueen and it arrives in your instance ready to send.

When is the best time to send a newsletter?

It depends entirely on your subscribers' inbox habits, and no tool can know those in advance. Pick a consistent day and hour so readers learn to expect you, then compare open behavior across a few scheduled sends and settle on what your own data supports.
