Use Copilot to draft a polite email to a client about a delay
Draft a professional, client-friendly email about a project delay in minutes using GitHub Copilot—no writing experience needed.
Hook: You’re running a project and a hiccup means you’ll miss the deadline. Instead of staring at a blank screen, you’ll have Copilot draft a clear, warm email you can send to your client in minutes—no writing experience required.
💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.
- A GitHub account (free or paid)
- The GitHub Copilot extension installed in your browser or IDE (or use copilot.github.com)
- About 5 minutes of your time
Copilot can draft the email, but it can’t send it for you—you’ll still need to copy and paste it into your email app.
Open Copilot in your browser
Open your browser and go to copilot.github.com. Look for a button like “Start Copilot” or “Try Copilot for free” in the centre of the page. Click it.
You’ll see a chat panel open on the right side of the screen. This is where you’ll type your request.
Draft a polite email to a client explaining a 3-day delay in delivering their project because of an unexpected server issue. Keep it professional, warm, and under 120 words.
You'll know it worked when the chat panel shows Copilot’s first draft of the email.

Refine the tone and details
Read Copilot’s first draft. If it’s too formal or too casual, tell Copilot how you’d like it adjusted. For example:
Make it a bit warmer and add a sentence offering a 10% discount on the next project as a goodwill gesture.
You'll know it worked when the draft now includes the warmer tone and the discount offer.

Check for accuracy
Read the email carefully. If Copilot missed a key detail—like the exact number of days delayed or the client’s name—tell it what to fix.
Change “3-day delay” to “a 5-day delay due to a server outage on 5 June” and add the client’s name, “Dear Sarah,” at the start.
You'll know it worked when the draft now includes the correct delay length, date, and client name.

Ask for a shorter version
If the email feels too long, ask Copilot to tighten it up.
Shorten this to 80 words or fewer while keeping it polite and professional.
You'll know it worked when the draft is now concise and still warm and clear.

Copy the final draft
Highlight the entire email in the chat panel and copy it (Ctrl+C or Cmd+C). Paste it (Ctrl+V or Cmd+V) into your email app.
You'll know it worked when the email is now in your compose window, ready to send.

Mistake: Forgetting to personalise the client’s name or project details. Fix: Always include the client’s name and the exact delay length in your prompt.
Mistake: Accepting the first draft without checking for accuracy. Fix: Read the draft carefully and ask Copilot to correct any missing or wrong details.
Mistake: Sending the email without reading it aloud first. Fix: Read the email aloud to make sure it sounds like you and matches your company’s voice.
Open copilot.github.com, paste the example prompt from Step 1, and send the first draft to yourself to review. You’ll have a client-ready email in under 5 minutes.
