Someone still has to create batch operation. It does not have to be you
A companion works the 3 operations your Mailcheck account exposes. It can create a batch operation, and every one of those waits on an approval card showing the batch operation before it changes.
Open the batch operation. Check it against something else. Write the change. Move to the next one. That is the Mailcheck afternoon nobody can hand off, and a companion does the whole pass and gives you back the batch, with nothing landing on a batch operation until you approve it.
What it can do is exactly what Mailcheck exposes to an account you authorise and nothing beyond it: 3 operations, 2 reads and 1 write. In practice that means it can create a batch operation, and work across the batch operations, batch operation statuses and process single emails.
The Mailcheck API stops at Mailcheck. 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 Mailcheck batch operations does a companion see?
2 of the 3 operations are reads.
Your account, not a guess at it: a companion can process single email and get batch operation status, and the full list below is the whole list, with nothing inferred from Mailcheck's documentation.
The batch operations are what most of this inventory is about, alongside the batch operation statuses. A companion can hold all 3 of these operations and forty open tabs in the same pass, which is how an afternoon of Mailcheck admin becomes a queue you review.
- Process Single Email
- Get Batch Operation Status
Can it change a batch operation without asking?
The one write operation there is waits for you.
A companion can create a batch operation, and each one is staged on an approval card first: you see the batch operation, the field and the new value before it lands in Mailcheck.
Nothing in Mailcheck is sent, changed or deleted on your behalf without that click, and a rejected card leaves the batch operation exactly as it was. The gate is the same one on every surface, described at security.
- Create Batch Operation
Can the batch operations pass run every Monday?
Yes.
Saved as a routine, the Mailcheck batch operations 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 product and engineering playbook catalogues the other recurring shapes of the engineering admin, the Mailcheck batch operations sweep among them, and finished runs are published at real runs.
