How to Chain Prompts Together: Email Drafting Edition

So far, you’ve learned the basics of prompt engineering and built a custom assistant. Now, let’s take it up a notch by creating a multi-step AI workflow — using prompt chaining. We’ll walk through a real-world task: drafting the perfect email.

🔗 What is Prompt Chaining?

Prompt chaining means using the output of one AI prompt as the input for the next. It’s a way to break complex tasks into smaller, manageable steps — and guide the AI to better results.

✉️ Use Case: Writing a Polished Email

We’ll guide the AI through 3 steps:

1. Generate key points
2. Create a rough email draft
3. Polish the final version

🧱 Step 1: Gather Key Points

You are a professional assistant. Ask the user what the email is about, who it's for, and what tone they want to use. Then summarize the key points to include.

Example Input:

I need to email a client about rescheduling our meeting. I want to stay polite but firm. They’ve rescheduled twice already.

Example Output:

Key Points:
- Request to reschedule the meeting
- Acknowledge previous changes
- Emphasize importance of locking in a time
- Maintain a polite and professional tone

🪄 Step 2: First Draft

Write a professional email using these key points:
- Request to reschedule the meeting
- Acknowledge previous changes
- Emphasize importance of locking in a time
- Maintain a polite and professional tone

Example Output:

Subject: Request to Confirm New Meeting Time

Hi [Client Name],

I hope you're doing well. I wanted to follow up regarding our meeting. I understand schedules can shift, and I appreciate your time so far.

Would it be possible to reschedule to a time that works best for you? Given the importance of this discussion, I’d like to ensure we can confirm a time that works for both of us.

Looking forward to your reply,
[Your Name]

🎯 Step 3: Polish the Final Version

Improve the following email for clarity and tone, and make it slightly more concise:

Example Input:

Hi [Client Name],

I hope you're doing well. I wanted to follow up regarding our meeting. I understand schedules can shift, and I appreciate your time so far.

Would it be possible to reschedule to a time that works best for you? Given the importance of this discussion, I’d like to ensure we can confirm a time that works for both of us.

Looking forward to your reply,
[Your Name]

Example Output:

Subject: Request to Reschedule

Hi [Client Name],

Hope you're doing well. I wanted to follow up on our meeting and see if we could confirm a new time. I understand things come up and appreciate your flexibility.

Given the importance of our discussion, I’d love to lock in a time that works for us both.

Best,
[Your Name]
