unstar removes Gmail’s STARRED system label from one or many messages. Use it after an automation has completed the work represented by a standard Gmail star.

Example

Remove the star from messages after applying a Completed label:
The Completed label must already exist in the selected Gmail account.

Inputs

Every input field also accepts a compatible Signal; the example chains the output of addLabel into unstar.

Output

The action returns a Signal<string[]> containing the modified message IDs in input order. This removes the standard STARRED label from individual messages. It does not change unrelated labels or other messages in the same thread.
