Lab 01 · Inbox Zero Sprint

Triage a 25-email Monday-morning inbox with AI: classify by urgency, summarize the two threads too long to read, and draft replies in three different tones — then prove every draft against the thread facts before anything gets "sent". Sixty minutes, free tools, and a triage habit you will keep.

Priya Nair is the office and admin manager at Meridian Facility Services Pvt Ltd, a fictional 200-person facilities company in Pune. She was off Friday. It is now 9:05 on Monday, her inbox shows 25 unread messages, and her first meeting is at 10:00. Two of the emails are long, tangled threads — a customer complaint and a vendor negotiation — and somewhere in the pile there is at least one thing that is not what it claims to be. Your job is to get Priya to a fully triaged inbox, with every reply drafted, edited into her voice, and fact-checked, in under an hour.

You will need

  • A chat AIfree ChatGPT, Claude, or Gemini all work; M365 Copilot if you have it.
  • A blank doc or notes file to act as your "outbox" — you will paste drafts there, not send anything.
  • Timeabout 60 minutes.
  • No real dataeverything below is synthetic and obviously fictional. Never run this exercise on a real inbox that contains customer or employee personal data unless your company has approved the tool.

The inbox

Here is Priya's unread list — sender, subject, and the first line of each message. Paste-ready.

The two threads that need summarizing before anyone can reply:

THREAD A - "Deep-clean complaint - Site 4" (Trentwood Hotels, our client)
28 Jul, Sunita Rao: Deep-clean of banquet hall was scheduled for 26 Jul.
  Team arrived 3 hours late and left carpet shampooing unfinished.
29 Jul, Priya Nair: Apologies - confirming with the site team, will revert.
30 Jul, Prakash (Site 4): Team was late due to transport strike. Carpet job
  finished next morning 7am before hotel opened. Photos attached.
30 Jul, Sunita Rao: Finished or not, my banquet manager lost half a day.
  I want a credit on the August invoice. We were billed Rs 14,800 for this
  deep-clean under invoice INV-2041.
01 Aug, Meridian billing (auto): Reminder - INV-2041 (deep-clean, Site 4,
  Rs 14,800) due 15 Aug.
04 Aug, Sunita Rao: Third time writing. No response since Thursday. I expect
  a full credit of Rs 18,400 against INV-2041, or we review the contract.
  Copying my regional head.
THREAD B - "Revised rates - housekeeping consumables" (Apex Supplies, vendor)
12 Jun, Rajesh Kulkarni: Requesting a call to discuss revised rates -
  raw material costs are up 9 percent.
13 Jun, Priya Nair: Call done today. Summary: we agreed you will send a
  revised rate card for REVIEW. No commitment given. Any revision applies
  only from the NEXT quarter after written approval.
27 Jul, Rajesh Kulkarni: As agreed on our 3 June call, sharing the revised
  rate card. Kindly note the new rates apply from 1 June as discussed.
  Invoice for June-July difference (Rs 42,300) attached.
02 Aug, Rajesh Kulkarni: Gentle reminder. Awaiting confirmation since last
  week. We have been servicing Meridian for 6 years and this delay in
  approving a small adjustment is disappointing.

Steps

  1. Set up the triage. Open your chat AI and paste the 25-line inbox list with this prompt: "You are helping an office manager triage email. Classify each message into: URGENT-TODAY, THIS-WEEK, DELEGATE, FYI-ARCHIVE, or SUSPICIOUS. Give a one-line reason per message. Present as a table." Do not paste the threads yet — triage works on the manifest alone.

  2. Audit the AI's triage before trusting it. Read every classification and reason. The AI is guessing from subject lines, exactly as a rushed human would — and a rushed human gets at least two of these wrong. Check specifically: does anything flagged urgent actually deserve it, and is anything dangerous sitting in a harmless-looking category? Correct the table yourself and note each correction — you will need the list at the end. Ask the AI to re-print the corrected table.

  3. Summarize Thread A. Paste the complaint thread with: "Summarize this client complaint thread in 5 bullet points: what happened, what the client wants, what our team says happened, current risk level, and any facts that do not add up." That last clause matters — you are explicitly inviting the AI to spot inconsistencies rather than smooth them over.

  4. Verify the summary against the thread. Take each bullet and find the exact line in the thread that supports it. Two things to check by hand: every rupee amount, and every date. If the AI's summary states what the client is asking for, confirm that number appears in the thread — and confirm it is consistent within the thread. Write down anything that conflicts. Do the same paste-summarize-verify pass for Thread B, asking specifically: "List every date and every amount mentioned, with who said it."

  5. Draft the client reply — apologetic but precise. Prompt: "Draft a reply to Sunita Rao. Tone: apologetic, professional, de-escalating. We accept the team arrived late. We will discuss a credit but must confirm the correct invoice amount first — do not commit to a specific credit figure. Under 150 words. Do not invent any facts not in the thread." Read the draft. If it commits to any amount, or apologizes for something the site team disputes without acknowledging their account, fix it.

  6. Draft the vendor reply — firm, not rude. Prompt: "Draft a reply to Rajesh at Apex Supplies. Tone: firm and factual. Point out exactly what our 13 June email agreed: revised rates were for review only, no retroactive application, changes only from next quarter after written approval. Decline the June-July difference invoice. Keep the relationship door open. Under 150 words." Check the draft quotes the real call date and terms from Thread B — not the vendor's version.

  7. Draft the internal replies — warm and quick. In one prompt, ask for three short replies: to Vikram (board visit — confirm plan by Wednesday, ask about parking count), to Shweta (water leakage — treat as today's priority, name the next step), and to Kiran (approve leave, one warm line). Internal notes should sound like a colleague, not a press release — if any draft says "I hope this email finds you well," delete that line.

  8. The 60-second check, then close the sprint. For each of the five drafts in your outbox doc: read it aloud once, verify every number and date against the source thread, confirm the tone matches the recipient, and confirm it makes no promise Priya is not authorized to make. Finally, ask the AI: "Turn what we just did into a reusable triage prompt I can paste every Monday." Save that prompt — it is the real take-home.

Pro Tip

Never let an AI draft commit money, dates, or apologies-with-admissions on your behalf — instruct it up front what it may not promise, then check that it obeyed.

Verify your work

A completed sprint has all of the following:

  • A triage table with all 25 emails classified — and at least two classifications you corrected by hand, with reasons.
  • One email flagged SUSPICIOUS and not replied to, reported instead.
  • Thread A summary with the client's demand and the billing discrepancy explicitly flagged, not averaged away.
  • Thread B summary with the two versions of the call date and the retroactivity claim called out.
  • Five edited drafts: client (apologetic, no committed amount), vendor (firm, cites the 13 June terms), and three internal notes that sound human.
  • Every number and date in every draft traced to a line in the source thread.
  • A saved, reusable Monday-triage prompt.
▸Answer key — the planted problems and what good output looks likeoptional deep dive — click to expand

Planted issue 1 — the phishing email (message 04). The sender domain is meridian-facilties.example — "facilities" is misspelled. A password-expiry email with a click link from a lookalike domain is a phishing pattern. Correct handling: classify SUSPICIOUS, do not click, do not reply, report to real IT. If your AI filed it under "internal request", that is the triage correction the lab expects you to catch.

Planted issue 2 — the fake urgency (message 07). A newsletter with URGENT in the subject. Correct classification: FYI-ARCHIVE. Anything that inherits urgency from its subject line alone is a triage failure.

Planted issue 3 — the amount discrepancy in Thread A. The client demands a credit of Rs 18,400, but the invoice she cites (INV-2041) is for Rs 14,800 — stated twice in the thread, once by her. The two numbers are a digit-swap apart. A correct reply commits to no figure and asks to reconcile the invoice amount. If your draft promised Rs 18,400 — or even Rs 14,800 — you gave away money without verification.

Planted issue 4 — the vendor's rewritten history in Thread B. Rajesh cites a "3 June call"; Priya's own email shows the call was 13 June, and its summary explicitly ruled out retroactive application. The vendor is claiming rates apply from 1 June — before the call happened on either date. A correct reply cites the 13 June email, declines the Rs 42,300 back-billing, and offers to review rates for next quarter.

Grading yourself: 4/4 issues caught = excellent. 3 = solid; re-read the one you missed and ask what check would have caught it. 2 or fewer = repeat the lab tomorrow with fresh eyes before moving on — this catching habit is the foundation for every later lab.

Expected classifications for the rest: URGENT-TODAY: 05, 06/14, 20 (leakage near a server room outranks almost everything). THIS-WEEK: 03, 08, 09/22, 10/19, 16, 24, 25. DELEGATE: 11 (reception can log the printer call), 13, 17, 23. FYI-ARCHIVE: 01 (reply takes 10 seconds — do it now), 02 (forward to accounts), 12, 15, 18, 21.

Key Takeaway:

AI turns a 25-email pile into a 60-minute sprint — but the value is in the audit, not the drafts. Classify with AI, verify with your own eyes, and never let a model commit an amount, a date, or an admission you have not checked against the thread.
