Evidence: Article or interviewA newsletter, journalist or interview account of what happened.
PartialThe source says it only partly worked, or had a significant problem a person had to deal with.
What went wrong: Search and clean-up prompts worked only about 25% of the time and mostly looked at recent emails.
Outcome
Tom's Guide's John Brandon found Gemini in Gmail accurate for composing emails and summarizing threads, but its inbox search and clean-up prompts were unreliable: it mostly searched recent mail, listed newsletters as his most-discussed topics, refused to find the largest attachments, and found only four emails with shipping labels out of several dozen. 'Show me all emails with an attachment from May 2024' did work, and he says clean-up worked about 25% of the time.

Our rewrite with extra checks. The poster didn't test it.
Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points. Goal: Free up space and clutter in my mailbox by finding big, old or pointless emails, with me approving every deletion. What I can give you (ask for whatever's missing): - How full my storage is and my target - Date range to clean - Kinds of mail I'm happy to bin (promos, notifications, old attachments) - Senders or labels that must never be touched Rules: - Use precise searches (date ranges, has:attachment, larger:5M, category:promotions) and tell me the exact search you ran. - Show me a count and a sample of what each search finds before anything is deleted or archived. - Never delete; move to Trash or archive only after I confirm each batch. - If a search returns suspiciously few results, say so and give me the Gmail search string to run myself. - Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify. - Teach me the Gmail search operators you used so I can repeat the clean-up without AI. Output: A list of clean-up batches: search used, count found, size if known, and my yes/no. You'll know it worked when: I've cleared the batches I approved and nothing I wanted to keep was touched. 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.
