Key-Point Co., Ltd. (Kobe City, Hyogo Prefecture, Representative Director: Masaharu Onishi, hereinafter "Key-Point"), a group company of Kokopelli Inc. (Chiyoda-ku, Tokyo, Representative Director & CEO: Shigeru Kondo, hereinafter "Kokopelli"), announced that its email sharing management system "GrpMail" and file transfer/sharing service "WebFile" will be implemented within the internal network of Chiba Shinkin Bank (Chiba City, Chiba Prefecture, Chairman: Hideki Ishibashi) starting July 2026. "GrpMail" and "WebFile" have been adopted by over 2,000 companies to date, supporting safe and smooth information sharing for businesses for over 20 years. The introduction of both services will significantly reduce the risk of email transmission errors and information leakage, and by centralizing file transfer and management, will contribute to the DX, operational efficiency, and security enhancement of financial institutions. Background of "GrpMail" and "WebFile" Implementation In the Shinkin Bank industry, business networks and the internet are physically separated. Therefore, external email and file transfer operations require moving to an internet-connected PC to perform tasks. Since "GrpMail" and "WebFile" can be accessed from the internal network, employees can perform email and file transfer tasks without moving from their seats, contributing to operational efficiency. Furthermore, by conducting file transfer operations through "WebFile," secure file transfer, sharing, and management are possible without relying on the conventional PPAP method (※). ※The PPAP method involves sending an encrypted ZIP file as an email attachment and then sending the password in a separate email. Features and Functions of "GrpMail" "GrpMail" is an innovative system that allows multiple users to share a single email address and manage emails centrally.
