Outcome

With over 200K unread messages, mostly junk, a long-time Gmail user asked Grok to help sort auto-generated email into keep-as-important, News or Promos, and unsubscribe or spam. The user applied the filters manually using Grok's search criteria, which were easy to verify, and three days later says the inbox shows only email from real people and messages tagged important.

Prompt Recreated prompt

The source didn't share its exact prompt, so we wrote this from what it describes.

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: Design Gmail filters that keep real people and important mail in my inbox and route the rest.

What I can give you (ask for whatever's missing):
- The kinds of mail I get most (I'll paste sender names or subjects)
- What I always want to see
- What I want to skim later
- What I never want

Rules:
- Group senders into: Important, skim-later labels, unsubscribe, spam.
- Write exact Gmail search strings for each filter and how to test them before applying.
- I'll apply filters myself; never ask for my password.
- Start small and check results before bulk actions like mark-all-read or delete.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A filter list with search strings, the label or action for each, and the order to apply them.

You'll know it worked when: my inbox shows only mail from people and things I marked important, and nothing I want is 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.

  • Clean up a Gmail inbox with Gemini's search prompts (hit or miss)Evidence: Article or interviewPartial

    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.
