Write 4 pass/fail checks for AI newsletter drafts

Practice: Saying who it's for. About 5 minutes.

About this exercise

Your team uses AI to draft the weekly customer newsletter, and the editor wants 4 checks to grade drafts. She wants the offer in the first sentence, exactly one link, a subject line under 50 characters, and no claims without a source in the product sheet. Write exactly 4 numbered lines, each 'N. Check: ... | Pass: ... | Fail: ...', binary only. Plain text, under 170 words.

Common mistakes when you ask AI for this

  • Getting a rating scale. The AI suggests rating 'engagement' and 'clarity' 1-5. Try: Say: "Binary only: each line has a Pass and a Fail."
  • Generic email checks. The AI doesn't know what your editor wants, so it invents checks like 'is compelling'. Try: List them: "offer first, one link, subject under 50 characters, claims backed by the product sheet."
  • Checks you can't count. 'Subject is short' gets a different answer from every reviewer. Try: Use numbers: "Fail if the subject is 50 characters or more."
  • A guide instead of checks. The AI writes newsletter tips with headings. Try: Be exact: "Exactly 4 lines: Check | Pass | Fail."

What a strong prompt includes

  • Names the editor's wants
  • Asks for pass/fail
  • Shows the line shape
  • Says exactly how many
  • Asks for plain text
