“Building a lasting, sustainable brand” is a goal for many companies. But actually achieving long-term success is a challenge. The phrase itself is not an operating guide, and without key strategies behind it, it can become just a slogan.

The key is to master the core strategies for managing your owned audience and combine them with modern member management tools, such as a CDP and LINE campaign and game tools. Understanding your members and increasing interaction with them is what drives real long-term growth and lasting success.

What is Smart Send Time?

Smart Send Time is a feature that uses data analysis and automation to predict, from each user’s past open history, when they are “most likely to open a message,” and then sends the message automatically at that time.

For example:

• Member A: usually checks LINE on Wednesdays at 9 p.m.
• Member B: often reads messages on weekdays at 8 a.m. while commuting

Based on these behaviors, the Smart Send Time system sets the best send time for each user individually, instead of sending to everyone at one fixed time. Messages are less likely to be ignored, and engagement rises sharply.

Why does Smart Send Time raise open rates so much?

1. Every customer has their own prime reading time

Consumers’ routines and habits vary widely. Traditional bulk sending ignores these differences, so messages may arrive at the wrong time and get lost in a sea of notifications. Smart Send Time pinpoints:

• Peak open times
• Device usage habits
• The times users are most likely to engage

Using behavioral data analysis and machine learning, the system keeps refining its send strategy, so the more you send, the more accurate and effective it gets.

2. Automation reduces manual errors

When Smart Send Time is integrated with a CDP, send scheduling is fully automated. There is no need to set times or build segments by hand, saving a great deal of marketing time and reducing the risk of missing the best send time because of an operating mistake.

3. Higher open rates = higher conversion rates

Getting a message seen is only the first step. As open rates rise, the whole conversion funnel improves. In real-world deployments, brands that adopted Smart Send Time saw:

• Average LINE message open rates rise 1.6 to 2 times
• Click-through and purchase conversion rates grow by 20% to 35% as a result

LINE Official Account plus a CDP: start smart sending

Smart Send Time needs complete “member behavior data” as its foundation, and that is exactly where a CDP (customer data platform) excels.

How does a CDP power smart sending?

• Integrates cross-platform data: Brings together sources such as the website, LINE, apps and POS
• Analyzes individual behavior precisely: Records every member’s opens, clicks, purchases and other actions
• Builds a personal prime-time model: Uses AI to predict each member’s best time to open, then sends through the right marketing channel (LINE, email, SMS) at a personalized time, with AI-driven automatic recommendations.

“A mother-and-baby products retailer using AI Smart Send Time raised its open rate by more than 30% and its total converted orders by 50%.” When you integrate your LINE Official Account into a CDP, you connect message delivery and data analysis in both directions, making your marketing faster, more precise and more effective.

Three steps to build a smart sending system

1. Integrate data: break down silos and build 360° user profiles

Tool combination	Focus
LINE OA + CDP	Connect chat behavior with purchase records
GA4 + CDP	Track browsing paths across devices
AI prediction model	Automatic “best send time”

2. Design automated journeys: triggers based on both “time + behavior”

• Random sending: send at a fixed time every day (avoiding the 8 to 9 a.m. commute peak); open rate 28%
• Advanced sending: when a user “abandons their cart,” send an offer 3 hours later; open rate 35%
• Smart sending: use RFM predictions to give high-value customers priority, personalized time slots; open rate 62%

3. Optimize continuously: a test → analyze → iterate loop

• A/B testing: compare CTR across different time slots
• Heat map analysis: find the prime time for each customer segment

Stop wasting the value of every message

In an age of message overload, “time” is the battleground for customer attention. Instead of firing blindly, aim smart and precise. Integrating Smart Send Time across LINE, email and text messages with a CDP not only improves message reach but also makes communication between brand and customer closer and more valuable.
