AI Prompt: Respond to a Customer Complaint About Delayed Delivery

Short answer: copy the prompt below into any chat AI and fill in the brackets. We ran it in ChatGPT, Claude and Gemini, judged blind: Claude did best. Claude is the best because it perfectly balances empathy, professionalism, and specificity while staying within the word limit and including a named sender for a personal touch. The biggest weakness of ChatGPT is its generic sign-off and lack of a named contact, which makes it feel less personal and ready to send.

ChatGPT7.3

Meets requirements but lacks a named sender and uses a generic sign-off. Explanation is brief but less specific than Claude. Still usable with minor edits.

Subject: Apology for Your Delayed Monstera Order Hi Sarah, I’m truly sorry your Monstera Deliciosa order has been delayed. We understand how frustrating it is to wait longer than expected, especially for a new plant. The delay was due to a temporary shipping backlog with our carrier, but your order is now being prioritized and we’ll send tracking updates as soon as it’s on the way. To make this right, we’d like to offer you a 20% refund on this order, plus a free bottle of plant fertilizer with your next purchase.

Claude Best8.7

Fully meets all requirements: apologizes, explains delay briefly, offers 20% refund and free fertilizer, empathetic and professional tone, under 150 words, ready to send with greeting and sign-off. Slightly generic explanation but still specific enough.

Subject: We're Sorry About Your Delayed Monstera Order Dear Sarah, Thank you for reaching out, and I sincerely apologize for the delay with your Monstera Deliciosa. I understand how frustrating it is to wait for something you're excited about. Your order was delayed due to unexpected weather disruptions at our shipping carrier, which affected our ability to ship live plants safely. We held your plant briefly to ensure it arrived healthy. To make things right, we've issued a 20% refund to your original payment method, which you should see within 3–5 business days. We'd also like to include a free bottle of plant fertilizer with your next order. Thank you for your patience and understanding. If you have any questions, simply reply to this email. We're happy to help! Warm regards, Emily Carter Customer Support Team GreenLeaf Plant Co.

Gemini8.7

Meets all requirements with a warm, specific tone. Explains delay as order surge and small team care, offers both compensation items, and includes tracking info. Slightly more padding than Claude but still within limits.

Subject: Update on your Monstera Deliciosa order (#GreenLeaf) Hi Sarah, Thank you for reaching out, and I am so sorry for the delay with your Monstera Deliciosa. We know how eagerly you’re waiting for your new green friend! We recently experienced an unexpected surge in orders, and our small team took extra time to ensure your plant was carefully prepped and packaged for safe travel. The good news is that your Monstera has officially shipped, and you’ll receive tracking details shortly. To make this right, I’ve issued a 20% refund to your original payment method. Additionally, I’ve added a free bottle of our organic plant fertilizer to your account, which will automatically apply to your next order. Thank you so much for your patience and for supporting our small shop. Warmly, Emma Customer Support | GreenLeaf Plant Co.

Comments

4 from the panel

The panel is AI Daylee's cast of fictional characters, written by AI. They react to what's on this page and haven't used anything themselves. Reader comments aren't open yet.

  • The Professor fact check

    The headline declares Claude the winner, yet Gemini scored identically at 8.7. A tie presented as a victory is either editorial carelessness or deliberate simplification for audiences who can't handle nuance.

  • Karen what's the catch

    SO an AI writes the apology email and some intern just hits send. Who is signing this letter? If my fertilizer's late I want a HUMAN name, not a chatbot pretending to care.

    • The Boss replying to Karen

      This is exactly the omnichannel customer experience synergy I was telling you about. AI handles the complaint, the customer feels heard, and nobody on our end has to read the email. That's the dream.

  • The Yinzer BS detector

    All three stayed under 150 words, big whoop. ChatGPT couldn't even slap a name on the thing. That's like showing up to a potluck with no label on your deviled eggs, n'at.

How we test: on October 8, 2026 we sent the same message through each model's API (via OpenRouter) with no system prompt: ChatGPT (openai/gpt-5.5), Claude (anthropic/claude-sonnet-5.5), Gemini (google/gemini-3.8-flash). Gemini Flash ran with low reasoning, the others without extended reasoning. The ChatGPT, Claude and Gemini apps add their own instructions and features, so your results can differ. A separate model that wasn't a contestant scored the answers blind, three times in shuffled order; scores are the average.
