About

JSMIX is a leading menswear brand specializing in plus-size apparel, offering a one-stop shopping experience across physical stores and e-commerce platforms. This case study details their strategic use of LINE's advanced marketing tools:

LINE Official Account (OA): Core communication platform.
OA+ (Targeting Plus): For segmentation and personalized messaging.
LINE LAP (LINE Ads Platform): For targeted customer acquisition.

These tools enabled JSMIX to enhance customer engagement and expand its reach in a niche market.

The Challenge

What went wrong

JSMIX, operating in the highly specialized plus-size menswear market, faced significant hurdles in customer acquisition and engagement. Traditional advertising channels proved inefficient in reaching their niche audience. While they had over 10,000 LINE Official Account friends, many became dormant after initial engagement, leading to missed opportunities. The brand needed to:

Acquire precise new customers efficiently, moving beyond generic outreach.
Re-engage existing, inactive LINE friends to maximize the value of their subscriber base.
Transition from generic mass messaging to personalized customer interactions to enhance relevance, maximize impact, and reduce high block rates.
Utilize LINE OA's full potential beyond basic features to drive deeper customer relationships and sales.

Solution Approach

How it was solved

Inspired by the LINE Editor Bootcamp, JSMIX adopted a sophisticated, multi-pronged strategy integrating LINE OA+ (Targeting Plus) and LINE LAP (LINE Ads Platform), especially during the crucial 618 sales event.

OA+ (Targeting Plus) for Segmentation & Personalization:

* Implemented an automated welcome survey for new LINE friends to proactively gather essential preferences (e.g., age, style, color, offer type).
* Leveraged OA+ to automatically tag friends based on their survey responses, achieving a remarkable 40% tag coverage across their friend base.
* Shifted from mass broadcasts to sending personalized, segmented messages (e.g., targeted clearance sales to discount-interested users), drastically improving message relevance.

LINE LAP (LINE Ads Platform) for Targeted Acquisition:

* Custom Audiences: Uploaded their official website member data to LAP to precisely target existing customers who had not yet joined the LINE Official Account, closing a critical marketing loop.
* Lookalike Audiences: Created expanded, similar audiences based on their most valuable customer segments, effectively broadening their reach with high-potential prospects.

This integrated approach allowed JSMIX to create a sophisticated, data-driven marketing ecosystem within LINE.

🏢 JSMIX

Operating in the highly niche plus-size menswear market, JSMIX used to struggle with acquiring the right customers and re-activating over 10,000 dormant LINE Official Account friends. Before the 618 sales event, we joined the LINE Editor Bootcamp and decided to fully leverage LINE OA+ (Targeting Plus) and LINE LAP (LINE Ads Platform) – a decision that completely transformed our marketing performance.

With OA+, we launched an automated welcome survey and auto-tagging system that achieved an impressive 40% tag coverage across our entire friend base in a very short time. This allowed us to move away from mass broadcasts and start sending truly personalized, segmented messages. The results were immediate: 30–40% higher open and click-through rates, and a remarkable 46% drop in block rates. Customers clearly felt we finally “understood what they wanted.”

At the same time, we uploaded our website member database to LAP to create Custom Audiences, re-targeting existing customers who hadn’t yet added our LINE OA, and built Lookalike Audiences to reach high-potential prospects. The outcome? Our LINE Official Account grew 6X during the 618 period, and because every new friend was tagged from day one, their conversion rates have been outstanding.

This strategy created a true closed-loop marketing system inside the LINE ecosystem: precise acquisition → automated segmentation → highly personalized re-marketing, all within a single platform. Efficiency and ROI have reached levels we never thought possible.

A huge thank you to the LINE team and these powerful tools – they helped JSMIX break free from ineffective traditional advertising and turned our LINE OA into the most powerful growth engine we’ve ever had!
