Hakuhodo DY ONE Enhances DialogOne®︎ LINE Notification Message Features
〜Supporting LY Corporation’s Latest Updates to Improve Communication and Business Outcomes〜

Tokyo, June 16, 2025 – Hakuhodo DY ONE Inc. has updated its proprietary marketing solution DialogOne®︎ to align with LY Corporation’s latest version of LINE notification messages. This enhancement optimizes how companies communicate with users via LIVE, helping businesses deliver more effective digital communications, increase customer engagement, and strengthen long-term relationships.

Background:

In March 2025, DialogOne®︎ underwent a major upgrade designed to make LINE-based communication seamless and stress-free for both companies and users.  

LY Corporation’s “LINE Notification Messages” feature enables companies to send essential updates to users even if the business is not registered as a LINE friend. This is achieved by securely hashing phone numbers, enhancing privacy and convenience. The feature is widely used for everyday communications like delivery confirmations and billing notifications and has been shown to improve message open rates compared to traditional channels such as email or SMS.

Previously, limitations and certification hurdles reduced adoption of this service. The latest version resolves these challenges by expanding its applications and simplifying deployment, allowing businesses to better leverage LINE’s communication power.

Overview of DialogOne®︎’s LINE Notification Message Features

1. Broader Range of Applications
The available message templates have been significantly expanded─ around 70 options─ helping companies address diverse communication needs and reach more customers.

• For Users:
  A secure, convenient channel to receive important notifications, such as delivery updates, order confirmations, or contract renewals, all via LINE ─without the need to add companies as LINE friends.
• For Companies:
  More touchpoints to engage customers during daily routines. These messages can also act as acquisition tools, helping businesses connect with the potential customers before official LINE friend registration occurs.

2. Streamlined Message Deployment

The dedicated message templates introduced by LY Corporation simplify the entire process ─from creation to delivery approval.

• For Companies:
  Standardizing layouts reduce development time, resource requirements, and costs, while simplifying the approval process. This enables faster, more efficient message delivery and improves overall business productivity.

DialogOne®︎ also consolidates and manages valuable user ID (uid) data, supporting advanced targeting, segmented messaging, customized rich menus, and ad placement within LINE or other channels.

In addition, DialogOne® will provide LINE notification messages without additional fees, making it easier for more companies to begin using the service.
