Halve LINE Friend Acquisition Costs! Launch of 'Rakuten-Specialized LINE Notification Message Feature' that Simultaneously Completes Rakuten Member Linkage

Greenwich Co., Ltd. announced the launch of a new 'LINE Notification Message' feature for Rakuten Market store operators, effective May 1, 2026. This service enables stores to acquire LINE friends and link Rakuten member IDs simultaneously at a low cost. By matching phone numbers, stores can send order confirmations directly via LINE for 8 yen per message, even to non-friends. This prompts users to add the store as a friend and link their Rakuten ID in one seamless process. A launch campaign offers free application support and unlimited use of the 'Rakuraku Line' segmentation tool.
