We will explain how to use ChatGPT to write business emails.

How to Write Business Emails with ChatGPT

  1. Log in to ChatGPT
  2. Enter the business email prompt in the message input field and send it
  3. ChatGPT automatically generates the business email

What is a Prompt?

Prompts are important for writing business emails with ChatGPT.

A prompt is a keyword or phrase used to instruct ChatGPT to generate text.

By using prompts (keywords or phrases) and providing detailed information about what you want it to write, ChatGPT can generate more accurate text.

Try to write your prompt as specifically as possible, including who you want to contact, what you want to say, and how you want to convey it.

Examples of ChatGPT Prompts for Business Emails

[Prompt for a mail requesting the sending of an invoice]

Subject: "Request for sending invoice"

Reason for invoice request: "Request an invoice for service usage fees"

Confirmation of destination information: "Confirm the destination for the invoice"

Specify the deadline: "Set a deadline for sending the invoice"

Closing words: "Thank you in advance"

Write the reason for the request specifically and give instructions as clearly as possible, such as setting the deadline date to "September 15, 2023."

If You Don't Know the Prompt, Just Ask ChatGPT

But I don't know how to write a prompt for a special case like this...

In such cases, if you ask ChatGPT, it will provide examples of how to write prompts.

Please tell me a prompt for an email to Mr. Yamada asking about hydraulic unit settings.

Something like that is perfectly fine.

Yes, like this, it wrote not just the prompt but the actual email too.

If you don't know something, try asking ChatGPT anything. If you are not satisfied with the generated text, try changing the way you give instructions.

It's such a hassle to read...

If you feel that way, you can use the AI voice tool Ondoku to have the content read aloud.

It Takes Time Both to Read and Write Emails

According to the Business Email Reality Survey 2022:

  • Daily average: Sent "16.27" Received "66.87"
  • Average time to read one email: 1 minute 24 seconds
  • Average time to write one email: 6 minutes 5 seconds

In other words, on average:

Just reading emails takes 1 hour and 10 minutes a day.

Just writing emails takes 1 hour and 40 minutes a day.

It can be seen that the time related to emails is about 3 hours per day.

This means some people spend almost half a day just on emails.

What a waste! Let's utilize AI so you can make things easier for yourself!

By mastering the method of writing business emails efficiently with ChatGPT, you can proceed with your daily work smoothly.

Also, the burden of reading time can be significantly reduced by having them read aloud.

Please make use of Ondoku for reading aloud!

Improve Efficiency by Listening with Audio

Listening to emails via audio is one way to make reading and writing business emails more efficient.

Time Saving

Listening to emails can be faster than reading them with your eyes, and the content can be easier to understand.

Possibility of Multitasking

By listening to emails, you can engage in "parallel work" such as starting to write a reply while listening to the content of the email.

Reduction of Eye Strain

Staring at a screen all day can tire your eyes. However, listening to emails via audio can reduce eye strain.

Prevention of Misreading and Oversights

Listening to emails makes misreading and oversights less likely to occur. This helps prevent mistakes.

To listen to emails via audio, you can use the voice assistants built into smartphones and computers, or use dedicated tools like Ondoku to listen easily.

Why don't you try checking business emails comfortably with Ondoku?
