What Makes a Good AI Prompt for Client Emails?

Before diving into the prompts, here's what makes them work well:

• Be specific: tell the AI your role, the client's situation, and the goal of the email.
• Set the tone: say whether you want it formal, warm, direct, or apologetic.
• Include key details: names, dates, context, and any important facts.
• Ask for a subject line: always ask the AI to include one.

The more detail you give, the better the result. Think of it like briefing a skilled assistant.

Thank you for sharing this it's a great idea. After reviewing the request, it falls outside the scope of our current agreement, so we wouldn't be able to include it within the existing project budget and timeline.

That said, we'd love to explore this as a separate add-on. If you'd like, I can put together a quick quote so we can discuss options.

Quick Tips to Get Better Results From AI Email Prompts.

• Always review before sending: AI gives you a strong draft, but personalise it to match your voice.
• Add specific names and dates: the more real context you include, the more relevant the output.
• Ask for multiple versions: try: "Give me 3 variations of this email: one formal, one casual, one brief".
• Specify word count: if you need a short email, say: "Keep it under 100 words".
• Iterate: if the first draft isn't quite right, just type: "Make it more direct" or "Add a stronger call to action".
