Sending coupons just increases blocks. What is the design/implementation to turn LINE into a fan-building funnel?

There is a common consultation regarding LINE operations for D2C and EC brands.

“I am sending messages, but it is not leading to sales,” “The block rate keeps rising,” “I am just sending coupons.”

This is not a delivery problem. It is a design problem.

Why are CRM and LINE design receiving rapid attention now?

Actually, this problem is not unique to your brand.

There is a structural change happening across the entire industry in the background.

1. Advertising costs continue to soar

Until now, many D2C brands have efficiently acquired new customers through retargeting ads.

However, due to the strengthening of cookie regulations, ad measurement accuracy has dropped, and the cost per acquisition (CPA) for new customers has risen significantly.

The model of “if you increase ads, you will sell” has reached its limit.

2. The value of first-party data is exploding

Now that user tracking via third-party data has become difficult, the value of customer data acquired directly by the company (purchase history, LINE open history, attributes, etc.) has become extremely high.

How much you can accumulate and utilize “your own unique customer data” that other companies cannot access will be the decisive difference from competitors.

3. The fusion of AI and CRM is progressing

As of 2026, the approach to customers is evolving through the fusion of AI and CRM.

We are in an era where AI analyzes customer data in real-time, detects customers at risk of churn, and automatically sends messages at the optimal timing.

To run this “AI engine,” high-quality customer data accumulated in the CRM is essential.

4. Rapid adoption in the Japanese market as well

The Japanese CRM market size is growing steadily and is projected to reach 920.3 billion yen in 2026.

In other words, the gap between brands that invest in CRM and LINE design and those that do not is widening rapidly right now.

Instagram/TikTok and LINE have completely different roles

I often hear people say, "It's fine because I'm posting on social media."

However, Instagram/TikTok and LINE have fundamentally different roles.

Instagram/TikTok

LINE

In other words, the correct division of roles is as follows.

Gain awareness on Instagram/TikTok and cultivate fans on LINE.

Only when these two are combined is LTV maximized.

Many D2C brands focus on Instagram while putting off LINE design.

There is a huge opportunity here.

Why distributing only coupons has its limits

If you keep sending coupons on LINE, purchases will occur in the short term.

However, in the customer's mind, it is recorded like this:

"This LINE just sends discount information"

As a result,

• The number of customers who won't buy without a coupon increases

• The more frequently you send messages, the more you get blocked

• LTV does not increase while advertising costs only rise

You fall into this structure.

The essence of LINE is not 'broadcasting' but 'design and implementation'

What D2C brands that are achieving results on LINE all have in common.

It is

designing and implementing 'who to send what to, why, and at what timing'

is what they are doing.

In current D2C, a model that relies solely on ads → LP → purchase is becoming difficult.

We are in an era where customers make decisions by crossing multiple touchpoints such as SNS, reviews, UGC, Amazon, and Rakuten.

That is precisely why designing and implementing the customer experience, including post-purchase LINE, CRM, and UGC, is directly linked to LTV and fan building.

What changes when design and implementation change

Coupon-centric LINE → 'Only discount information arrives' → Blocked

Designed and implemented LINE → 'This brand understands me' → Become a fan

Specifically, we design and implement the following.

• Design and direction of post-purchase habituation support messaging

• Segment design and implementation direction tailored to customer status

• Design for natural guidance to F2 conversion and recurring purchases

• Design and implementation direction for personalized messaging based on behavioral triggers

• Support up to LINE Official Account and L-Step configuration direction

• Separate quote provided if rich menu or image production is required

• KPI design and monthly improvement support
