Note

Starting prompt:

Review this email and make suggestions to improve it.

In this simple prompt, you start with the basic Goal: to review an email for improvements. As you can see though, there isn't much information to start with.

Element Example
Basic prompt:
Start with a Goal
Review this email and make suggestions to improve it.
Good prompt:
Add Context
Adding Context can help Copilot understand the intention for the email and what improvements you want to see.

"...to our client and make suggestions to improve its clarity and professionalism."
Better prompt:
Specify Source(s)
The Source for this prompt is assumed to be the email you're writing in Outlook.

"...this email."
Best prompt:
Set clear Expectations
Lastly, adding Expectations can help Copilot understand how you want the table to look and sound.

"Please suggest changes to the email's subject line, greeting, body text, and closing. Please ensure that the email is concise, free of errors, and uses a professional tone."

Note

Crafted prompt:

Review this email to our client and make suggestions to improve its clarity and professionalism. Please suggest changes to the email's subject line, greeting, body text, and closing. Please ensure that the email is concise, free of errors, and uses a professional tone.

This prompt gives Copilot everything it needs to come up with a good answer, including the Goal, Context, Source, and Expectations.
