Estimated delivery: Thursday.”\nAnswer: IMPORTANT\n📌 This is relevant information for the user – do not remove.\n\nMessage:\n“You left something in your cart! Only today –15% off your purchase!”\nAnswer: OFFER\n📌 Typical marketing reminder, no actual value.\n\nMessage:\n“Hi, we noticed you didn’t download our free e-book. Download now to discover 10 ways to boost sales.”\nAnswer: OFFER\n📌 Marketing prompt, lacks valuable content.\n\nMessage:\n“Attached is the invoice for the service completed last month. Please contact me with any questions.”\nAnswer: IMPORTANT\n📌 Invoice = important message.\n\nMessage:\n“Today only! Free shipping and discounts up to 30% in our store!”\nAnswer: OFFER\n📌 Promotion, typical sales message.\n\nMessage:\n“Hi, I saw your listing online and I’m interested in working with you. Can we talk by phone?”\nAnswer: IMPORTANT\n📌 Message from a real person = potential lead.\n\nMessage:\n“Win a new iPhone! Click here to claim your prize!”\nAnswer: SPAM\n📌 No need to explain – scam/spam.\n\nMessage:\n“I’d like to ask if you offer individual training sessions?”\nAnswer: IMPORTANT\n📌 A real inquiry from a potential customer.\n\nMessage:\n“Register now for free 7-day access to XYZ tool.”\nAnswer: OFFER\n📌 Advertising offer, not inherently important."
