LINE Marketing Strategy: Segments, Campaign Calendar & KPIs

#Start With Goals, Not the Send Button

A LINE marketing strategy decides who gets which message, when, and how you'll judge it. In practice: pick one goal per month, split friends into the few segments LINE OA can really target (attributes, audiences, chat tags), schedule sends around your market's calendar, cap frequency, and check opens, clicks and blocks in LINE OA Manager's Insight.

Every pushed message uses quota (one recipient, one message), and every irrelevant one invites a block. Strategy is how you send fewer messages for better results.

Choose one main goal per month and two to four sends that serve it. When you're ready to produce and schedule those messages, our LINE broadcast tool creates the visuals with AI and sends them to all friends or to a list of user IDs. For the mechanics of sending (steps, counting rules, timing), see the LINE OA broadcast guide; this article stays on strategy.

#Segment Friends With What LINE OA Offers

LINE OA Manager has two built-in ways to message part of your friend list, attribute filters and audiences, plus chat tags you add yourself. Each comes with minimums:

Sources: LINE Thailand help center, LINE Japan's manual on audiences and filtered broadcasts, and the LINE Taiwan help center.

Two caveats before you build on attributes:

• Target reach isn't your friend count. It's the number of friends LINE can target by gender, age or region, counting only people active on LINE whose demographics LINE knows with high certainty (Messaging API reference). Small accounts often can't filter by attributes yet.
• Attributes are estimates. LINE Japan's manual explains that age and gender are inferred from LINE usage, updated daily and applied with data about three days old, so expect some misses.

#Five segments most SMEs can actually run

Your own data counts too. Tag chats as they happen ("asked for price", "booked", "wholesale") and turn tags into audiences later. Developers can upload LINE user IDs that your own channel received through the Messaging API; lists collected elsewhere won't match and may break privacy law. Our guide to LINE CRM and customer management covers how to keep this data organized.

#Build a Campaign Calendar per Market

Plan the year in one table, then give each month one main campaign and one supporting message. Holidays that follow the lunar calendar move every year, so check the exact date before you schedule.

Then add your own dates (store anniversary, new menu, seasonal stock, end-of-season clearance) and a monthly payday moment: the end of the month in Thailand, around the 25th in Japan, when many companies pay salaries.

A workable routine:

1. Fix the year's big moments from the table above.
2. For each month, write the goal, the segment and the offer in one line.
3. Do the quota math before you commit (see the budget math below).
4. Prepare creatives two weeks ahead, so no send is rushed.
5. After each send, note what happened: opens, clicks, blocks and sales.

#Lifecycle Messages: Welcome, Follow-up, Win-back

Some messages should go out because of what a friend did, not because of the date. LINE OA Manager covers the basics natively:

Thailand's help center describes step messages that send automatically by conditions such as friendship duration (up to 20 step messages), and Japan's manual describes ステップ配信 with branches by friend-add route, days since adding and attributes; both count toward the quota. Keep lifecycle flows short, two or three useful messages, because a long sequence sent to everyone is an easy way to collect blocks.

#Personalize Without a CRM

• Personalize by segment, not by name. The biggest gain usually comes from sending a different message to a different group: the branch near them, the product they clicked, the service they booked.
• Use display names where LINE supports them. LINE OA Manager can insert the friend's display name in some message types: greeting messages and auto-replies in Japan's manual, step messages in Thailand's help center.
• Match the language. Thai for Thai customers, Japanese for Japan, Traditional Chinese for Taiwan. If you serve tourists, add an "English" rich-menu button that triggers an English reply.
• Match the moment. Lunch offers before lunch, weekend offers on Thursday or Friday, reminders the day before an appointment, then check what your own numbers say.
• Keep one voice. The same polite particles (in Thai, ครับ or ค่ะ), the same signature, the same visual style. In LineBot.pro, a saved brand profile (tone, colour, rules) is applied to every generation.

#Frequency and Block-Rate Management

LINE OA Manager shows friends added, target reach and blocks on the account home page and in Insight. Two numbers keep your frequency honest:

• Block rate = blocks ÷ friends. LINE's friend count includes people who later blocked you, so this shows the share you have lost. Track it monthly.
• Blocks after each send. Compare blocks in the 48 hours after a broadcast with a normal day. A spike means the message, the audience or the timing missed.

Frequency rules that cost nothing:

1. Start with two to four planned sends a month and change only when the data says so.
2. Don't send the same offer twice to the same people; retarget the clickers instead.
3. Use targeting to cut volume: a send to the 1,000 friends who clicked costs an eighth of a send to all 8,000.
4. Schedule at odd minutes. LINE Japan's manual notes that sends scheduled at round times such as 00:00 or 12:00 can be delayed by congestion and suggests times like 12:11 (LINE manual).
5. When quota is tight, set a maximum number of messages for the send; LINE then picks recipients at random. Thailand, Japan and Taiwan all offer this option.

#KPIs You Can Track in LINE OA Manager

Definitions follow LINE's help pages for Thailand and Japan. Work out two ratios yourself: open rate = opens ÷ delivered and click rate = click users ÷ opens (LINE Japan's campaign report also divides clicks by opens). Japan's report collects each message's numbers for 14 days after sending and doesn't show values under 20, so judge small sends over several months.

Add UTM parameters to every link, for example ?utm_source=line&utm_medium=broadcast&utm_campaign=songkran, so your web analytics shows sales from LINE whichever tool sent the message. LineBot.pro campaigns show delivery status, follower count and remaining quota, not opens or clicks. When you need LINE's open and click statistics for a campaign, send that one from LINE OA Manager; you can still create the image in LineBot.pro and upload it there.

#Testing Ideas

• Built-in A/B test (Thailand). The web version of LINE OA Manager offers an A/B test under advanced settings for accounts with a target reach of 5,000 or more. You create variants, LINE sends each to a share of your audience, and within three days of the start you can send the best one to the friends who haven't received it (LINE Thailand help center).
• Smaller accounts: compare like with like. Change one thing at a time (image, headline, offer, button text or send time) and compare two sends on the same weekday and hour.
• Try new ideas on a random slice. The maximum-number-of-messages option sends to a random selection of your audience, a cheap way to test a new idea before a full send.
• Judge on clicks, not opens. Opens depend on timing and notifications; clicks show interest in the offer.
• Keep a log. Date, segment, variable, delivered, opens, click users, blocks, sales. A difference of a few clicks on a few hundred recipients is noise, so repeat a test before you change your playbook.

#Budget Math: Messages per Month

Monthly messages are the sum of recipients × sends. Three illustrative plans priced with official rates (tax excluded, October 2026):

Targeting is also a budget lever. A Thai shop with 8,000 friends that sends four broadcasts to everyone needs 32,000 messages (Pro, ฿1,780). One broadcast to all plus three sends to the 2,000 most engaged friends needs 14,000 (Basic, ฿1,280): ฿500 a month less, and fewer reasons to block.

#Where LineBot.pro Helps

LineBot.pro covers the production and sending side of this plan:

• Campaign visuals with AI. Describe the offer and get a rich message, one Flex bubble with image, headline, text and button (8 credits), or a banner in LINE sizes (8 credits). In AI Studio, one click makes a matching kit: a wide banner, a rich message and a 3-button compact rich menu, with your saved brand profile applied. See the AI rich message maker.
• Broadcast or schedule from Campaigns. Connect your LINE OA with its channel credentials, generate the message from a prompt, preview it, then send it to all friends or to a pasted list of LINE user IDs, now or at a scheduled time. Sending costs 0 credits (LINE's monthly quota applies), and each campaign shows delivery status, your follower count and remaining quota.
• Not included: open and click analytics, tag-based segments, drip sequences and A/B tests. Use LINE OA Manager's targeting and Insight for those, as described above.

Plan your next campaign in LineBot.pro. New accounts get 50 free credits with no card needed; after that, one-time credit packs with no subscription (pricing).

#FAQ

Q: How often should a business send LINE messages to its friends?

LINE doesn't set a number. Start with two to four planned sends a month, each tied to that month's goal, and watch blocks in the 48 hours after every send. If blocks jump, narrow the audience or send less; if clicks hold up, test one more send.

Q: What is target reach in LINE OA?

Target reach is the number of friends LINE can target by gender, age or region, counting only people active on LINE whose demographics LINE knows with high certainty. It's lower than your friend count, and attribute-filtered sends need at least 100 (more than 100 in Taiwan).

Q: Can I send a LINE message to only some friends?

Yes. Use attribute filters (such as gender, age, OS, area and friendship duration) or audiences (people who clicked or opened past messages, chat tags, uploaded user IDs). Most audience types need at least 50 people, and messages to segments still count toward your quota.

Q: Which KPIs matter most for LINE marketing?

Click users per send, blocks after each send, and the sales or bookings you can attribute with UTM links. Open rate helps with timing; friend growth matters only if the new friends stay.

Q: Does LINE OA have A/B testing?

In Thailand, the web version of LINE OA Manager offers an A/B test for accounts with a target reach of 5,000 or more. Smaller accounts can compare like-for-like sends manually, changing one variable at a time.
