M-fro Inc. (Headquarters: Shibuya-ku, Tokyo; Representative: Norinori Kitawaki) conducted an "Awareness Survey on AI in Business Emails" targeting 500 working individuals and compiled the data into rankings.

With the spread of generative AI, more people are using AI to create content for business emails and chats. Having AI write emails saves time and reduces stress for those who are not good at writing.

However, some people may worry, "How will the recipient feel if they realize it was written by AI?"

M-fro Inc., which operates the Craudia Recruitment Video Production Agency Service (https://craudia-saiyo-movie.com/), conducted a survey of 500 working individuals on "AI in Business Emails" and summarized the results in a ranking format.

Kenji Kuhara, representative of Pro Innovation Inc., provided comments on the survey results.

[Survey Results Summary]

- 60.4% have noticed that messages from others were "written by AI."

60.4% have noticed that messages from others were "written by AI."

When asked "Have you ever noticed that messages from others were 'written by AI'?" among 500 working individuals, a total of 60.4% answered "frequently (7.0%)" or "occasionally (53.4%)."

This surpasses "never (39.6%)," indicating that a majority have experienced feeling "this must have been created by AI" in their work communications. This suggests that AI is widely permeating business communication.

On the other hand, about 40% responded that they have "never noticed it." Some comments included, "AI performance is high these days, so I don't think I'd notice," suggesting that even when AI is used, the text is accepted as natural.

57.6% do not particularly mind if messages from others are "written by AI."

Regarding how people feel about messages from others being "written by AI," a majority (57.6%) responded, "I don't particularly mind."

Conversely, those who answered "I feel it's a bit of a shortcut (29.6%)" or "I don't feel very good about it (12.8%)" accounted for a combined 42.4%.

A relatively large number of people accept the use of AI in work-related communications. This is likely influenced by AI already being a familiar tool in both work and private life.

However, there were comments like, "It's fine for work-related messages, but I don't like it for thank-yous or requests." This indicates a desire for AI to be used appropriately depending on the situation, such as whether the priority is to convey information clearly or to convey feelings.

It can be said that consideration and ingenuity to add "humanity" are required in some cases, rather than relying solely on AI.

The reason for not minding messages from others being "written by AI" is "as long as the content is conveyed."

When asked the reason for not minding AI-generated text among 288 respondents, the overwhelming majority (51.0%) cited "as long as the content is conveyed," with over half of them selecting this option. This shows that in work-related communications, people tend to prioritize "whether the necessary information is conveyed correctly" over "who created the text and how."

Furthermore, opinions such as "I use it myself too (15.6%)" and "It's easy to understand" suggest that people accept AI not with resistance, but as a tool to facilitate work.

Many people accept AI communications, prioritizing efficiency and practicality.

<1st Place: As long as the content is conveyed>

- "In business, it's fine as long as the intended message is conveyed. I personally think it's better to have AI proofread than to make mistakes (Male, 20s)"

- "As long as the important parts are conveyed, I don't mind if the writing style is a bit unnatural. Some people send messages with strange wording even if it's not AI-generated (Male, 30s)"

- "It's different for private communication, but for business writing, I don't mind as long as I understand the main points (Female, 40s)"

Unlike private communication, work communication prioritizes smooth information sharing over deepening relationships. Therefore, many people accept it as long as the necessary information is written clearly, without concern for who wrote it.

Comments like "Some human-written texts are hard to understand" and "It's better to have AI proofread" indicate a focus on "quality" over the method of writing.

<2nd Place: I use it myself>

- "I use many AI tools myself and love them. But I wish they would remove symbols before sending (Female, 30s)"

- "I also lack writing skills and sometimes rely on AI, so I assume others feel the same way (Female, 40s)"

Many people also said, "Since I use it myself, I don't think anything of it when others use it." If you use it yourself, you can accept it as natural when others use AI. You can understand their circumstances.

For those who are not confident in their writing skills or use AI for work efficiency, using AI for communication is not unusual.

<3rd Place: It's easy to understand>

- "I find it easier to read text summarized by AI than text written by humans, so I don't mind (Female, 20s)"

- "For general email content, I don't mind at all. I feel better receiving a well-written email from AI than one with incorrect wording (Female, 30s)"

- "The main points are clearly organized, and it's often easy to reply. If the content is good, I think using AI is a form of work efficiency (Male, 30s)"

Emails generated by AI are often easy to read because they are summarized in bullet points or have a clean structure. Therefore, some respondents said, "It's easier to understand than when a human writes it."

In business emails, "readability," "clarity," and "transmissibility" are prioritized, so it's easy to think it's acceptable if it's easy to understand.

This is especially valuable for people who read and process many emails and chats throughout the day.

<4th Place: It helps with efficiency>

- "The sender's time is also limited, and it's understandable to want to cut down on time if possible (Male, 20s)"

- "I don't feel the need to manually input work-related messages. Thinking up text can be surprisingly time-consuming and draining. I prioritize efficiency (Female, 30s)"

- "As long as it doesn't interfere with work, I actually feel like they are someone who values their time (Female, 40s)"

Composing emails can require more time and concentration than expected, especially for difficult or complex content.

However, in many workplaces where results are expected within limited time, spending too much time on email composition can be considered "wasteful." Therefore, some people believe that "it's natural to use AI if it can reduce the burden of composing emails."

By reducing the time and effort spent on email composition, it becomes easier to focus on more important tasks. Some people highly value the pursuit of efficiency through AI.

<5th Place: It's natural to use it>

- "As AI has developed, I just think 'Of course some people are using it' (Female, 20s)"

- "In this day and age, using AI is normal, so I thought 'This is the era we live in' and didn't mind (Male, 40s)"

- "It's become normal to use AI, so I just think 'Ah, they're using it' (Female, 50s)"

Regardless of whether they use AI themselves, some people feel that "using AI is normal these days."

AI is widely integrated and established in society, so it is beginning to be recognized as a common tool in the workplace. If you consider using AI to be natural, you will not feel surprised or uncomfortable when the other party uses AI.

60.8% have used "AI-generated text" in their own communications.

When asked "Do you use 'AI-generated text' in your communications?" a majority (60.8%) answered "yes," with "frequently (19.0%)" and "occasionally (41.8%)" combined. AI is already widely used in business communication.

On the other hand, about 40% of respondents do not use AI, indicating that not everyone actively utilizes it.

As the survey also showed voices emphasizing "communicating in one's own words," usage varies depending on individual perspectives.

Conclusion

In this survey, over 60% of respondents have experienced noticing that messages from others were AI-generated, and over 60% of respondents themselves use AI in business communications. This shows that AI is widely used for creating text for emails and chats in the business world.

As AI usage becomes more common, a majority of respondents answered that they "don't particularly mind" AI-generated messages. Many also praised its practicality, such as clarity of content and work efficiency.

However, it is also true that over 40% of people have negative impressions, such as "it feels like a shortcut" or "I don't feel very good about it." It was also suggested that if messages are recognized as AI-generated, it could be a disadvantage in terms of enthusiasm and sincerity, with reasons like "feelings are not conveyed" and "I feel disrespected."

Ultimately, a stance that does not rely solely on AI, such as final checks and revisions, is important.

Comments from Kenji Kuhara

It's not that emails written by AI are bad, but rather that emails created without much consideration for the recipient's feelings and situation feel unnatural. Even if the text is well-organized, if you can't see "how the sender wants it to be received," it feels a bit shallow.

However, it's not good to just put feelings into it; it's also a problem if the message becomes difficult to understand due to excessive emotion. Ultimately, it's important to strike a balance between tone and clarity according to the recipient and situation.

With AI becoming more accessible, perhaps it's become more noticeable than the skill of writing whether the person is truly engaging with the recipient.
