About this exercise

Write the notice email to Odile at Brantley Tools. Subject line first (under 8 words), then "Hi Odile,". Include one line showing the math exactly like "48,000 x 1.05 = 50,400", the effective date, and the date the notice was due. No marketing language, no discounts, no urgency. End with "Kofi". Plain text, under 100 words.

Common mistakes when you ask AI for this

  • Copying marketing language. The AI pulls "game-changing" and "act now" from the notes. Try: Say: "No marketing language, no discounts, no urgency."
  • Missing subject or sign-off. The AI skips the subject line or ends with a long closing. Try: Say: "Line 1 is Subject:, then Hi Odile, and end with Kofi."
  • Skipping the math line. The AI writes "a 5% increase" without the arithmetic. Try: Say: "Include one line like 48,000 x 1.05 = 50,400."
  • Missing the dates. The AI leaves out the effective date or the notice deadline. Try: Say: "State the Mar 1 effective date and the Dec 31 notice date."
  • Getting markdown back. AI adds bold and headings by default, which show up as stray symbols where this is pasted. Try: Say "plain text, no bold, no headings, no asterisks".
  • Trusting the AI to count words. The AI runs long and cannot count its own words. Try: Cap each part ("each line under 12 words") and add "under N words in total".
