Recommend on an event sponsorship using last year's actual leads

About this exercise

Your CMO, Joan, must decide on a $15,000 conference sponsorship. Write a prompt for exactly 3 plain-text lines: "Math:" with the full cost divided by expected leads based on last year's actual leads from the same event, "Target:" with the target CPL and whether the result is above or below it, and "Recommendation:" Sponsor or Decline with a reason under 12 words. Under 70 words.

Common mistakes when you ask AI for this

• Using the vendor's 100 leads. The AI uses the organizer's number, giving $170. Try: Say: "Use last year's actual leads (60), not the vendor's estimate."
• Forgetting travel costs. The AI divides $15,000 only. Try: Say: "Full cost includes the $2,000 travel."
• Liking the event. The AI weighs the CEO's enthusiasm and the speaking slot. Try: Say: "Decide only on CPL against the target."
• Letting markdown through. AI adds bold text and headings by default. Try: Add: "Plain text only, no bold, no headings."
• Trusting the AI to count words. AI is bad at counting and often runs past a word limit. Try: Cap each part (for example "each line under 15 words") so the total lands well under the limit.

What a strong prompt includes

• Names the three labels
• Uses actual leads
• Includes all costs
• Compares to target
• Caps reason and length
