Both Raksul Inc. and Plaid Inc. are now collaborating on the enhancement of direct marketing techniques for businesses through customer data and web browsing behavior. The joint solution will cover the entire process, from audience selection and personalized content to response tracking, performance measurement and campaign improvements.

In March 2025, the company launched Raksul DM Mail with Chiku Takubin Co., Ltd., a Seino Group company, addressing delivery costs and time amid rising logistics expenses and postage rates. In July 2025, Raksul introduced Personalized DM and began integrating the service with Plaid’s customer experience platform, KARTE.

Raksul’s Personalized DM supports around 30 formats for targeted communication.

Sales campaigns are being jointly carried out by both companies, and they will gradually roll out the solution to their customers. They have also considered expanding the initiative to offline platforms such as flyers for analytics-based campaign planning and monitoring.
