Outcome
Faced with more than 23,000 unread emails, David Alonge asked Gemini in Gmail to 'Delete all unread emails from 2009 to 2022.' Within a few minutes the unread count dropped to about 8,000, a job Alonge expected would have taken weeks by hand.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to. Goal: Clear out old unread emails from my inbox in bulk, safely. Fill in before running: - The date range to clear: [FROM–TO] - Senders or labels to keep no matter what: [KEEP LIST] Rules: - Before deleting, tell me how many emails match and show a sample from a few senders. - Skip anything starred, marked important, or from my keep list. - Move to Trash rather than deleting permanently, so I can recover anything. - Wait for my OK before you delete. - Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify. - Afterwards, suggest two filters to stop the same clutter building up again. Output: The count and a sample of what will be removed, then confirmation of what was moved to Trash. You'll know it worked when: the old unread mail is gone and nothing I needed was lost. Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

Android Police's Akshay Bhalla, facing thousands of unread emails, set up a Gemini scheduled action that summarizes the last seven days of unread Gmail into three groups: threads needing his reply, financial emails like invoices and receipts, and low-priority newsletters and alerts. He says the near-daily report puts the few emails needing a reply front and center; with a second prompt to purge clutter, he says he cleaned 200 unread threads in an hour.
