[Case Study] N-Asset Reduces Email Creation Time by 50% Using AI in 'Re:lation'

Ingeage Inc. (Headquarters: Osaka City, Osaka Prefecture; President and CEO: Tetsuya Wada), provider of the communication platform 'Re:lation (Relation)' with over 6,000 companies (※1) using the service, announces the publication of a case study on the implementation of 'Re:lation' by N-Asset Co., Ltd. (Headquarters: Kawasaki City, Kanagawa Prefecture; Representative Director: Takashi Yoshimura), the top rental brokerage firm in Takatsu Ward, Kawasaki City.

◆ Background of Implementation

Industry-wide Challenge: 'Black Box' of Response Management in Property Management

Property management involves complex communication with three parties—tenants, owners, and contractors—and requires long-term accumulation of historical context with clients. However, traditional CRM systems or personal email-based responses often lead to information silos. Unresolved cases discovered after staff departures have made this 'black box' of operations a major industry-wide challenge.

At N-Asset, although group email addresses were included in CC, actual replies were sent from personal addresses, creating risks of information silos. Additionally, diverse customer communication channels such as LINE, SMS, and phone calls could not be centrally managed in existing systems, making reliable history tracking and operational efficiency urgent priorities.

◆ Results of Implementation

Complete Elimination of Personal Emails and 50% Reduction in Email Creation Time via AI

To address these challenges, N-Asset adopted 'Re:lation,' a platform that comprehensively covers all customer communication channels. They established a bold operational policy: completely removing personal email addresses from business cards and consolidating all customer-facing communication into shared 'Re:lation' addresses. By further leveraging the latest feature, the 'AI Email Agent,' they dramatically reduced email creation time by 50%, simultaneously achieving significant operational efficiency and eliminating information silos.

◆ Specific Initiatives

① Drastic Efficiency Gains via 'AI Email Agent'

By simply entering key points for a reply, the system automatically generates appropriate text, cutting email creation time in half compared to previous methods.

② Elimination of Information Silos through Complete Removal of Personal Emails

By fully sharing all communications across the team, staff consultations and managerial oversight became more active. Early detection of potential issues significantly reduced customer complaints.

③ Information Visibility via Mobile App

Staff can instantly search and confirm past response histories from smartphones, even while off-site or commuting, and respond immediately. This has also enhanced the psychological safety of junior staff with less experience.

◆ Comment from Mr. Hosoyama of N-Asset Co., Ltd.

"We were able to consolidate previously scattered information into one place, creating a situation where 'as long as we check here, we can understand all customer interactions.' Re:lation is truly a pioneering tool for information centralization for our company."
