Direct Mail for Just 90 Yen per Piece – From Design to Delivery! Share Chirashi, Adopted by 1,200 B2C Companies, Launches New B2B-Focused Service 'Share Envelope Direct Mail' Starting August 2026

Design-a Inc. (Headquarters: Hakata-ku, Fukuoka; CEO: Takayuki Shikou, hereinafter 'Design-a'), the operator of the shared and subscription-based posting service 'Share Chirashi'—which has surpassed 1 million monthly distributions nationwide and over 1,200 cumulative corporate contracts—announces the launch of its first B2B (business-to-business) specialized marketing service. Starting August 2026, the company will offer 'Share Envelope,' a shared direct mail service where postage costs are shared among multiple companies.

■ Background of the New 'Share Envelope' Service and Early Adoption Trends

In today’s B2B marketing landscape, customer acquisition costs (CPA) for web advertising (such as search and social media ads) continue to rise. Due to intensifying competition, an increasing number of companies are recognizing the limitations of relying solely on digital channels for customer acquisition. Meanwhile, direct mail (DM) offers high potential effectiveness by enabling direct outreach to decision-makers within target companies. However, the processes of list acquisition, design, printing, and mailing have traditionally involved significant costs and labor, creating a major barrier to entry.

To address this, Design-a has applied its proven B2C expertise in 'sharing advertising costs to achieve ultra-low pricing' to the B2B sector. The result is 'Share Envelope'—a groundbreaking new service that delivers marketing materials directly to target businesses at a one-stop cost of just 90 yen per piece.

This innovative cost-performance model has already generated significant interest ahead of launch. Major cable television (CATV) operators and large franchise headquarters actively expanding nationwide have already committed to adopting the service.

■ Four Innovative Features of 'Share Envelope'

1. 【The Shock of 90 Yen per Piece】
Achieves an unprecedented low price of 90 yen (excluding tax) per piece, all-inclusive of design, printing, and postage. This flat rate covers not only address list extraction and postage but also the printing of A4-sized promotional materials and even the cost of one-sided design creation—an all-in-one solution.

2. Precise 'Industry-Segmented Mailing' to Targeted Sectors
Recipients can be selected by specific industry or business type, such as 'real estate businesses,' 'clinics (hospitals),' 'beauty salons,' and 'restaurants.' This eliminates unnecessary costs and enables highly accurate market targeting.

3. Flexibility to Start Small: '1 Contract, 1,000 Pieces Minimum'
Responding to corporate needs for initial test marketing in limited areas or industries, the service supports small-lot contracts starting from just 1,000 pieces. Companies can begin immediately with low risk, without requiring large-scale budget allocation.

4. 'Shared (Ride-Share)' Structure Across Industries to Boost Open Rates
Multiple companies’ promotional materials are bundled into a single envelope for delivery. In B2B contexts, this allows decision-makers to easily compare services relevant to their business, increasing the likelihood of the envelope being opened and read compared to standalone DM campaigns.

■ Future Outlook

'Share Envelope' will officially launch in August 2026. Design-a aims to strongly support B2B marketing for SMEs, startups, and regional businesses struggling with the overcrowded digital advertising space. In addition to its existing posting services, the company will contribute to the activation of business-to-business transactions.
