Gmail unread search operators
Gmail label:unread vs is:unread: which unread search operator should you use?
Use is:unread for the clearest unread-state search in Gmail. Use label:unread when you see it in older Gmail operator examples, then combine unread searches with in:anywhere, in:inbox, sender, subject, and date operators to find the messages hiding outside your normal inbox.
Short answer: use is:unread first.
is:unread is the clearest Gmail search operator for messages currently marked unread. label:unread targets the same unread state in many examples, but is:unread is easier to read, easier to combine, and less ambiguous when you are building a repeatable cleanup search.
Useful Gmail unread searches

Why unread cleanup keeps coming back
Gmail search operators help you find the backlog. They do not stop the next wave of unknown senders from creating new unread noise. KeepKnown handles that second problem by moving non-contact senders out of the inbox before they become another unread count to triage.
