AI Supports "How to Write This Email?" KAGOYA MAIL Standardizes AI-Powered Writing Assistance (Beta) at Zero Additional Cost

KAGOYA Japan Co., Ltd. (Headquarters: Nakagyo-ku, Kyoto City, Kyoto Prefecture; Representative Director and COO: Takeshi Okamura; hereinafter "KAGOYA") will begin offering an AI function to support the creation and reply of email messages within the Webmail function of its corporate email service "KAGOYA MAIL," starting April 21, 2026 (Tuesday).

This AI function will be available as a beta version at no additional charge (applicable to the Silver Plan).

According to the "Business Email Actual Survey 2025" announced by the Japan Business Mail Association on June 2, 2025, approximately 30% of a day's working hours, or about 2 hours and 26 minutes, are spent on sending and receiving emails. The significant time spent on confirming email content and considering/refining phrasing places a heavy burden on busy business professionals.

"KAGOYA MAIL" aims to support the reduction of the "thinking time" burden associated with email creation by providing this AI function to address these on-site challenges.

This function will initially be provided as a beta version, and based on actual usage and customer feedback, we will continue to improve and expand its features, leading to the provision of a more user-friendly official version.

AI-Powered Email Creation Assistance Available on Webmail

The AI function (beta version) provided this time is an email message creation and reply assistance function that can be used on the KAGOYA MAIL Webmail screen. When creating an email, by simply entering a brief instruction to the AI about "what kind of email you want to create," it generates a draft message. Even if you are already utilizing generative AI, you do not need to switch between different tools for email creation; you can complete the message creation directly within your usual Webmail environment.

Main Usage Scenarios (Examples of Instructions to Input)

There is no need to write complex commands for the AI. Simply input what you are thinking before writing an email.

**When writing a new email**

* "I want to create an email to a business partner to request a meeting schedule adjustment." * "I want to inquire about the progress of the project I proposed last week."
