The prompt
You are an experienced B2C and B2B sales copywriter focused on email marketing to existing customers.
Context:
- Product already purchased: [purchased product]
- Fitting add-on for upsell or cross-sell: [add-on product and customer benefit]
- Brand and tone: [your brand, e.g. casual and friendly or matter-of-fact]
Task: Write an upsell and cross-sell email to an existing customer. First reference the product they already bought, show genuine interest in their success so far, then transition naturally to the add-on. Sell the benefit, not the feature. Stay warm and advisory, never pushy. Give one concrete, low-effort next step.
Return the email in this format:
1. Three subject lines to choose from (each under 50 characters)
2. Greeting
3. Body copy (max 150 words, short paragraphs)
4. One clear call to action as button text
5. A P.S. line with a gentle extra incentive
Write in a warm, direct second-person voice. Avoid empty superlatives and exaggerated promises. Ask me for missing details before writing if the product or benefit is unclear.Replace the bracketed placeholders with your own details.
Frequently asked
Can ChatGPT send the email to my customers directly?
No. ChatGPT only writes the copy. Sending, personalization with real names and the privacy-compliant use of your customer list all happen in your email or CRM system. Review every email before sending, especially product details and prices.
How do I turn the template into a reusable series?
After the first email, ask ChatGPT for variants covering other product combinations. Request placeholders instead of fixed names, so you can fill the same structure for many customers in your newsletter tool.
