Read every campaign, draft every subscriber, approve in one pass
A companion works the 3 operations your listmonk account exposes. It can create a subscriber and create list, and every one of those waits on an approval card showing the campaign before it changes.
Open the campaign. Check it against something else. Write the change. Move to the next one. That is the listmonk afternoon nobody can hand off, and a companion does the whole pass and gives you back the batch, with nothing landing on a campaign until you approve it.
What it can do is exactly what listmonk exposes to an account you authorise and nothing beyond it: 3 operations, no reads and 3 writes. In practice that means it can create a subscriber, create list and create a campaign, and work across the campaigns and subscribers.
The listmonk API stops at listmonk. A companion does not. The same run opens the customer's website, the supplier portal, the internal tool somebody built in 2019, because it is working the browser you are already signed into rather than calling in from outside it.
Which listmonk campaigns does a companion see?
In the tab.
listmonk exposes no read operation to a connected account, so a companion opens listmonk in the session you are already signed into and reads the screens you would.
The campaigns are what most of this inventory is about, alongside the subscribers. A companion can hold all 3 of these operations and forty open tabs in the same pass, which is how an afternoon of listmonk admin becomes a queue you review.
Can it change a campaign without asking?
All 3 write operations wait for you.
A companion can create a subscriber, create list and create a campaign, and each one is staged on an approval card first: you see the campaign, the field and the new value before it lands in listmonk.
Nothing in listmonk is sent, changed or deleted on your behalf without that click, and a rejected card leaves the campaign exactly as it was. The gate is the same one on every surface, described at security.

Can the campaigns pass run every Monday?
Yes.
Saved as a routine, the listmonk campaigns pass runs at the hour you pick: the Monday sweep, the overnight refresh, the Friday check. Keep Awake holds the machine awake for the length of a run, so a scheduled pass finishes with the lid closed.
The marketing playbook catalogues the other recurring shapes of campaign admin, the listmonk campaigns sweep among them, and finished runs are published at real runs.
