Filter messages by subject

I need the inbox narrowed to messages with the subject 'Invoice dispute' so I can triage them before the 3pm call. Show only threads whose subject line exactly contains Invoice dispute, newest first, and include unread only. Confirm there are no other threads that look like disputes but use different phrasing.

Before I hunt for disputed invoices, make the subject filter less painful for reviewers: surface counts of unread vs read, highlight any threads with attachments, and flag threads older than seven days so the ops lead can push for resolution.

I searched for Invoice dispute and got 327 threads — many are unrelated because the subject text varies. I have Jamie in ops and Priya in finance waiting for a clean list. Which likely reason is causing the noise, and what precise subject-filter rule should I use now to get only bona fide invoice disputes for the 3pm call?

Across the last three months I lose time fishing for disputes because people write subjects like Billing issue, Charge question, or Invoice dispute — inconsistent wording costs hours. What habit should I change in our team to standardize subjects and cut triage time by at least half? Give the email subject rule and the one-line instruction I can paste in a template.
