Using ChatGPT for email copywriting: our process and results

We have integrated ChatGPT into our email copywriting workflow. Here is how we use it effectively.

What works well

• First drafts of product update emails
• Subject line variations (generate 20, pick the best 3)
• Rephrasing existing copy for different segments
• Writing email sequences from an outline

What still needs human editing

• Brand voice consistency (AI tends toward generic)
• Technical accuracy (always fact-check)
• Emotional resonance for sensitive topics
• Humor and cultural references

Our prompt framework

We use a system prompt that includes our brand guidelines, tone of voice examples, and audience description. Then we provide specific instructions for each email. This produces much better output than generic prompts.

AI has cut our copywriting time by about 40%, but human oversight remains essential for quality.
