Your Gmail cleanup tool found nothing because your mailbox is the wrong shape

Description and use

Gmail cleanup tools that rely on fixed categories fail for inboxes full of many small messages from a few senders. Enumerating senders and counting all messages per sender lets users accurately identify and delete clutter.

Problem

Inbox cleanup tools rely on fixed category searches that miss clutter in mailboxes with many small, non‑promotional messages, leading to ineffective cleanup.

Outcome

By counting messages per sender instead of relying on category searches, users can accurately identify and remove large volumes of clutter, even in mailboxes that are not promotion‑heavy.

Workflow

• 1. Sample the inbox with diverse searches (e.g., older_than:2y, is:unread, after:2026/01/01) and note senders.
• 2. For each frequent sender, run a full Gmail search (e.g., from:[email protected]) to get the exact count.
• 3. Sort senders by count and decide which to act on.
• 4. Apply exclusions (e.g., -is:starred -invoice) in the same search used for counting.
• 5. Delete or archive messages from selected senders via the extension or manually.
• 6. Repeat periodically to maintain a clean inbox.

Evidence

Category searches get written before anyone sees your mail

The question that works on every mailbox shape is not "what category is this" but "who keeps sending me things"
