unmarkAsImportant removes Gmail’s IMPORTANT system label from one or many messages. Use it when an automation has determined that mail no longer belongs in Gmail’s Important view.
Example
Clear the importance marker from newly received automated reports:Inputs
Every input field also accepts a compatible
Signal; the example passes the filtered message ID signal directly.
Output
The action returns aSignal<string[]> containing the modified message IDs in input order.
Gmail’s own importance classifier can add IMPORTANT again later. This action changes only the supplied messages, not the other messages in their threads.
