A collection of prompts for writing business emails efficiently with ChatGPT

AI technology has developed, and it has become an era where various tasks can be done!

Business emails can also be created easily and efficiently using AI . Rather, it's a waste not to do it.


I will explain how to write a business email using ChatGPT.

How to write business emails with ChatGPT

  1. Login to ChatGPT
  2. Enter a business email prompt in the message input field and send
  3. ChatGPT automatically generates business emails

What is a prompt

Prompts are important for writing business emails in ChatGPT.

Prompts are keywords or phrases that tell ChatGPT to generate sentences.

By using prompts (keywords or phrases) and providing details about what you want people to write about, ChatGPT can generate more accurate sentences.

Be as specific as possible in your prompt about who, what, what, and how you want to say it.

ChatGPT business email prompt example

[Prompt for email asking to send invoice]

Subject: "Request for billing"

Reason for invoice request: "Request an invoice for the service usage fee"

Confirmation of shipping information: "Confirm billing address"

Specify deadline: "Set deadline for sending invoice"
