CRM PLUS on LINE vs Penny Blackfor Shopify (2026)
CRM PLUS on LINE and Penny Black target distinct aspects of customer communication and marketing for Shopify merchants. CRM PLUS on LINE focuses on digital engagement via the LINE messaging platform, enabling automated messages based on customer data and integration with Shopify Flow. Its strength lies in its ability to personalize and automate digital interactions, appealing to merchants looking to leverage LINE for customer relationship management. A key feature is the ability to deliver tabbed rich menus or dedicated rich menus to specific customers. However, social logins such as LINE Login are only available for Shopify Plus users. Penny Black, conversely, addresses a more traditional, tangible approach by focusing on personalized marketing inserts added to physical order packages. Its advantage lies in grabbing customer attention upon delivery and offering trackable analytics for insert effectiveness. It's best suited for merchants prioritizing a physical touchpoint to reinforce brand loyalty and drive repeat purchases. It allows personalized inserts based on real customer data. The primary difference is that CRM PLUS on LINE leverages a digital channel while Penny Black capitalizes on the physical unboxing experience. The rating on Penny Black is concerning and could indicate issues with the app or a very new launch.

Our Verdict
For merchants heavily invested in the LINE platform, particularly those targeting customers in regions where LINE is prevalent (e.g., Japan), CRM PLUS on LINE offers a powerful way to automate and personalize customer communication. The existing positive reviews (38 reviews, 5/5 rating) provide some confidence. However, Shopify Plus users gain additional benefits with LINE Login. Consider the learning curve associated with Shopify Flow integration.
Penny Black addresses a different niche – those wanting to enhance the physical unboxing experience. Its value lies in creating a tangible connection with customers. However, the complete absence of reviews and a 0/5 rating is a significant red flag. Merchants should proceed with extreme caution and potentially wait for user feedback before committing to this app. If customer experience and the 'wow' factor upon opening a package is prioritized over the immediacy of digital communication, Penny Black might be considered pending positive future updates and ratings. A/B testing different inserts would be crucial to ensure a positive ROI.
Common Questions
Which app is easier to set up and use?
CRM PLUS on LINE likely requires more technical setup due to the LINE integration and Shopify Flow. Penny Black may be simpler if it focuses solely on insert design and printing, but this is speculative due to the lack of reviews.
Which app is better for driving immediate sales?
CRM PLUS on LINE, with its automated abandoned checkout messages and restock notifications, likely offers a more direct route to immediate sales. Penny Black's impact is more indirect, focusing on long-term loyalty and repeat purchases.
Which app is more scalable?
CRM PLUS on LINE, integrated with Shopify Flow, probably offers greater scalability in terms of automation and personalization as the business grows. The scalability of Penny Black depends on the printing and fulfillment process for the inserts.
Is one app better suited to a specific product type?
Penny Black might be more effective for products that lend themselves to visual appeal and creating a memorable unboxing experience (e.g., beauty products, fashion items). CRM PLUS on LINE is product-agnostic, focusing on communication regardless of the product.
What is the biggest risk associated with each app?
The biggest risk with CRM PLUS on LINE is potentially ineffective messaging or over-communication if not carefully managed. The biggest risk with Penny Black is the complete lack of reviews, raising concerns about the app's functionality, reliability, and support.
