How should a LINE Official Account and a LINE Community divide the work between them?

The two run in different directions. An Official Account is a one-to-one channel from brand to individual, which suits customer service, order notifications, membership benefits, and segmented messaging, and only the recipient sees the message. A LINE Community is a shared space for many people at once, and its value comes from conversation among members, where the brand acts more as a host than a broadcaster. A common combination in practice is to grow discussion and relationships in the community, then guide people with a specific need into the Official Account so that service and post-purchase communication happen in a one-to-one setting.

Sending too many messages gets you blocked, so what frequency should you aim for?

Rather than asking about frequency, ask whether each individual message is useful to the person receiving it. Blocking usually has less to do with how often you send than with receiving a run of content that has nothing to do with you. A workable approach is basic segmentation first: separate buyers from non-buyers, recently engaged from long dormant, and customers of different product lines, so that everyone receives something they might plausibly care about. Watch how blocking and engagement move after each send and adjust to the actual response, rather than applying a fixed number.

Can you message customers through the Official Account asking them to leave a positive review?

You can invite customers to leave a genuine review, but you cannot exchange rewards for positive ones, and you cannot specify a star rating or dictate what should be written. Trading discounts or gifts for favorable reviews runs into platform rules and misleading-advertising concerns at the same time. The dependable approach is to make people aware the channel exists at the moment service is complete and they are visibly satisfied, include a directly clickable link to lower the effort involved, and leave whether to write, and what to write, entirely to them.

LINE Official Account Marketing Guide

Most LINE Official Accounts run by brands in Taiwan look much the same: a promotion every few days, a follower count creeping up, a block count creeping up alongside it, and eventually somebody asking whether any of this is doing anything.

The problem is not the tool. It is the positioning. LINE is the dominant messaging app in Taiwan, used by most of the population for everyday conversation, and an Official Account is one of the few communication channels you genuinely own — no algorithm decides who sees it, and the message lands directly in the recipient’s chat list. Using it only for promotions means running the lowest-value activity available down a direct line.

The three roles an Official Account plays for Taiwanese brands

A customer service channel. For a great many Taiwanese consumers, adding a brand on LINE and asking a question feels far more natural than making a phone call or sending an email. How well that channel is handled feeds directly into what appears in public reviews — a large share of negative reviews start with nobody answering a question.

A carrier for membership and orders. Queue numbers, appointment confirmations, shipping notices, warranty expiry reminders — transaction-related messages like these are best delivered in a one-to-one setting, and are the least likely to feel like an intrusion.

A segmented communication channel. This is the part most brands never activate: sending the same message to everybody produces dramatically different results from sending different content according to each customer’s situation.

All three roles can coexist, but they need to be kept distinct. Stuffing a customer service channel full of promotions sacrifices the most valuable use it has.

How the Official Account divides up against LINE Community

These two get discussed interchangeably more than almost anything else, and their properties are in fact opposites.

Dimension	Official Account	LINE Community
Direction of the relationship	Brand to individual, one-to-one	Members to each other, many-to-many
Who can see a message	Only the recipient	Every member
The brand’s role	Service provider, notifier	Host, facilitator
Content that fits	Orders, benefits, tailored advice	Discussion, questions, shared experience
Main risk	Getting blocked	Becoming a noticeboard and losing members

The combination that runs most smoothly in practice is this: let the community carry relationships and discussion, and let the Official Account carry service and conversion. When somebody raises a specific problem in the community that needs individual handling, move it to the Official Account; conversely, someone who has experienced a brand genuinely responding on the Official Account is more inclined to join the community.

How to run the community itself, including breaking the ice and moderation principles, is covered fully in The Complete Guide to LINE Community Word-of-Mouth Marketing and is not repeated here.

Where followers should come from

The follower count is not the objective in itself. The source determines whether this group is worth anything later.

Natural points in the transaction flow. Checkout, shipping notifications, after-sales service, appointment confirmation — inviting people at moments when they already need the information produces high opt-in rates and clear intent.

Physical locations. For brands with stores or events, the venue is the best entry point. Put it at the checkout counter, on the table, inside the packaging, paired with a specific reason (check an order, claim membership benefits, book an appointment) rather than a bare “add our Official Account.”

Content and service entry points. Making LINE the primary contact method on your website, in social profiles, and on FAQ pages naturally brings in people who have a reason to get in touch.

A source to avoid: trading a high-value gift for the follow. What you get is a list of people who came for the gift and block you once they have it, and every subsequent send pushes the block rate higher. This is the same category of error as subsidizing people who were going to buy anyway, described in Designing a Referral Program — get the incentive wrong and volume goes up while quality goes down.

The first message after the follow determines retention. Plenty of brands drop a promotional image straight in, which tells the recipient this place is nothing but advertising. A better approach covers three things: what they can do here (check orders, book, ask questions), roughly what they will receive, and one feature they can use right now. If the first message feels useful, tolerance for everything afterward is much higher.

Segmented messaging: the key to reducing blocking

Blocking usually happens not because there were too many messages, but because of a run of content with nothing to do with the recipient.

The most basic and most effective cuts:

Buyers vs. non-buyers. The former suit repeat purchase, maintenance reminders, and new products; the latter need help understanding the product and reducing the uncertainty of a first purchase
Recently engaged vs. long dormant. Continuing to send at high frequency to a dormant list is the main source of blocking
Product line or need category. Someone who buys baby products and someone who buys pet supplies receiving the same message means one of them feels intruded upon
Post-purchase stage. Just received, used for a while, approaching running out or expiring — what you should say at those three points has nothing in common

When watching your metrics, blocking is the most honest signal you have. Looking at how blocking and engagement move after each send is more useful than deciding in advance on a number of messages per week. Whether the content is right is not something you guess at; it is something you adjust to the response.

Turning the Official Account into a word-of-mouth collection channel

This is the account’s most underrated use. You are holding a group of people who have bought, used the product, and are willing to stay in contact — exactly the people best qualified to speak.

Post-purchase review invitations

Timing matters more than wording. Invite a review when the item has just arrived and has not actually been used, and you get a review about the delivery. Wait until the product has genuinely been used for a while and you get an account with something in it.

Lower the effort. Include a link that opens directly, so the person does not have to search, find the page, then find the review entry point. Every extra step costs you a portion of the group.

Choose who you ask. Inviting customers who have already expressed satisfaction is more sensible than blanket-sending to the whole list. A blanket send is also a reminder to dissatisfied people to go and leave a review.

You cannot exchange rewards for positive reviews, and you cannot specify a rating or the content. This line is clear both in platform rules and in the regulations; for detail, see Word-of-Mouth Marketing Compliance in Taiwan. For the overall approach to managing ratings, see The Complete Guide to Raising Your Google Maps Rating, and for how review mechanics work on e-commerce platforms, see The Complete Guide to Shopee and momo Reviews.

Referral codes and introduction mechanics

The Official Account is the most natural place to issue and track referral codes: the person is already receiving messages there, and claiming, checking, and sharing all happen in the same conversation. For the design principles — choosing between two-sided and one-sided rewards, which step to attach the reward to, how to prevent abuse — see Designing a Referral Program.

Catching negative signals early

A customer complaining in your Official Account is actually good news: they chose to raise it privately instead of going straight to a public platform and leaving a review. Answer that channel quickly and specifically enough and a great many public negative reviews never happen at all. For the sequence to follow when something does escalate, see The Brand Negative Review Crisis Playbook.

How to think about the cost

LINE Official Account pricing is adjusted by LINE from time to time, so what follows covers the mechanism and how to reason about it; for current plans and rates, refer to LINE’s latest official announcements.

Two things are enough to grasp. First, message volume is usually the main cost variable, so sending to everybody does not only damage relationships, it directly inflates spending. Second, after segmentation, total message volume often falls while results improve — because you have stopped sending to people who did not need it.

Put differently, segmentation is not an advanced technique. It is the basic move that improves cost and experience at the same time. For what to do first when the budget is limited, see Word-of-Mouth Budget Planning for Small and Medium Businesses.

Three common mistakes

Treating the follower count as the result. An account with a high follower count and almost no engagement means nothing except cost. What actually matters is how many people reply, click a link, and buy again.

Making every message a promotion. Nobody keeps a conversation open in order to see advertising every day. There has to be content in the mix that is useful to them and is not selling anything, or the channel does not hold.

Letting customer service go dead. An auto-reply standing in front and a human who never arrives is the most brand-damaging way to run an Official Account. Taiwanese consumers have very little tolerance for adding a brand on LINE and finding nobody there, and along the decision path described in How Taiwanese Consumers Search for Reviews, that experience feeds straight into public reviews.

The real value of an Official Account is not how many people you can message at any moment. It is that this group of people is willing to keep a conversation open for you. Use it as a loudspeaker and it will eventually be switched off; use it as a channel for service and for collecting word of mouth and it becomes one of the few assets an algorithm cannot touch.
