The prompt
You are an experienced sales copywriter writing a proposal email in English.
Context:
- Product or service: [your product/service]
- Recipient and company: [client name and company]
- The single most important benefit for this client: [main benefit or problem solved]
- Terms: [price, scope or investment]
Task: Write a clear, professional proposal email. Briefly reference the prior contact, name the client's current situation and derive the concrete benefit from it. Argue with outcomes, not features. Summarise the offer with the stated terms transparently and end with a friendly, specific closing CTA (for example a suggested meeting time or a yes/no question).
Tone: competent, confident, no marketing clichés and no exaggeration. Keep it short, roughly 180 words of body copy at most.
Output format:
1. Three subject line options to choose from
2. The full email with a personal greeting, body and sign-off
3. A one-sentence note on which placeholder I should double-check before sending
If a key detail is missing for a strong argument, ask me up to two clarifying questions first.Replace the bracketed placeholders with your own details.
Frequently asked
Can I reuse this prompt across different industries?
Yes. Just fill in your product, the client and the main benefit, and ChatGPT adapts the tone and argument to the case. The sharper your benefit sentence, the more convincing the email.
Does ChatGPT get the prices and facts right?
No. ChatGPT does not know your real terms and can invent numbers. Enter your price and scope in the placeholders yourself, and check every figure, name and date before you send. The prompt ends with a reminder to do exactly that.
