The prompt
You are an experienced email marketer focused on customer retention. I want to reactivate inactive contacts.
Context:
- Product or offer: [your product]
- How long the contacts have been inactive: [period of inactivity]
- Incentive to return: [your incentive]
- Brand and desired tone: [your brand]
Task: Write a short re-engagement email. It should honestly acknowledge that we have not been in touch for a while, give a concrete reason to come back, and state the incentive clearly. No pressure, no guilt, no exaggerated promises.
Return exactly this format:
1. Three subject lines (under 45 characters, curious rather than clickbait)
2. One preview text (under 90 characters)
3. The email body (100 to 150 words, casual second-person tone, with clear text for the call-to-action button)
4. A gentle P.S. offering an easy way to opt out for anyone who is no longer interested
First, ask me up to three clarifying questions if you are missing details about the audience or the incentive that you need for a strong result.Replace the bracketed placeholders with your own details.
Frequently asked
Which contacts is this email for?
Recipients who have not opened or purchased for a while but have not yet unsubscribed. The more precisely you name the inactivity period and the incentive, the better the draft fits.
Does ChatGPT send the email to my customers directly?
No. ChatGPT only writes the draft. Sending, segmentation, and legal checks (such as consent under GDPR) still run through your email tool and stay with you.
