There are roughly 53 million LINE users in Thailand. That is not a typo. In a country of 72 million people, nearly three out of four use LINE every day — to chat with friends, pay for street food, check the news, and talk to businesses.
If your business is not on LINE, you are invisible to most of your customers.
This guide covers everything: setting up your LINE Official Account, choosing the right plan, building rich menus, growing followers, automating replies, and measuring what works. Whether you run a hotel in Phuket, a clinic in Bangkok, or a Shopee store from your living room, this is the playbook.
Why LINE Dominates Thailand
Thailand is not like the West. Facebook Messenger, WhatsApp, email — they all exist here, but none of them come close to LINE.
The numbers tell the story:
- 53 million+ monthly active LINE users in Thailand
- 90%+ smartphone penetration across the country
- LINE message open rates: 60-70% compared to 20% for email
- 3x higher engagement than a Facebook page alone
- LINE is the number one app on Thai phones by daily usage
LINE is where Thai people live. They use it to message family, order food, transfer money through LINE Pay, and interact with brands. When a Thai customer wants to contact your business, their first instinct is to search for your LINE account — not visit your website, not send an email.
For Thai businesses, LINE is not just another marketing channel. It is the marketing channel.
Setting Up LINE Official Account
Getting started takes about 15 minutes. Here is the step-by-step:
Step 1: Create your account Go to manager.line.biz and sign up with your personal LINE account. One person creates the account, then you can add team members later.
Step 2: Choose your account type Select "Business Account" and fill in your business name, category, and subcategory. Use your real business name — this is what customers will see when they add you.
Step 3: Complete your profile Upload your logo as the profile image (at least 640x640 pixels). Write a short status message (20 characters max) and a longer description. Add your address, phone number, and business hours.
Step 4: Get your LINE ID You get a random ID like @123abcde for free. For a premium ID (like @yourbrandname), there is a one-time fee of ฿800. Worth it if you want customers to find you by name.
Step 5: Set up your greeting message This is the first message customers see when they add you. Make it count. Include who you are, what you offer, and how they can get help. Keep it under 500 characters.
Step 6: Share your account Add a LINE button to your website, print QR codes for your shop, and share your LINE link on social media. The format is line.me/R/ti/p/@yourID.
That is it. You are live. Now let us make it actually work.
Free vs Paid LINE OA Plans
LINE offers three plans. The right one depends on how many messages you send per month.
| Feature | Free | Light | Standard |
|---|---|---|---|
| Monthly fee | ฿0 | ฿1,200/mo | ฿4,000/mo |
| Free messages/month | 200 | 5,000 | 30,000 |
| Extra messages | Not available | ฿0.10/message | ฿0.05/message |
| Rich menu | Yes | Yes | Yes |
| Auto-reply | Yes | Yes | Yes |
| 1:1 chat | Yes | Yes | Yes |
| Broadcast messages | Yes | Yes | Yes |
| Audience targeting | No | Yes | Yes |
| API access | No | Yes | Yes |
Which plan should you pick?
Start with Free if you have fewer than 200 customer interactions per month. Most small restaurants, freelancers, and new shops fall here.
Move to Light (฿1,200/mo) once you are regularly hitting 200 messages. This is the sweet spot for spas, small hotels, and local clinics. You also unlock audience targeting, so you can send promotions only to customers who have visited before.
Go Standard (฿4,000/mo) when you are sending thousands of broadcast messages. Large hotels, restaurant chains, and e-commerce sellers with big follower lists need this tier.
The key thing to know: 1:1 reply messages are free on all plans. Only broadcast messages count toward your limit. So if most of your conversations are customers messaging you first, the Free plan lasts longer than you think.
Building an Effective Rich Menu
The rich menu is the grid of buttons that appears at the bottom of your LINE chat. It is the single most valuable feature of LINE OA because customers tap it constantly.
What makes a good rich menu:
- Keep it to 3-6 buttons. More than that and each button is too small to tap comfortably.
- Use clear icons and labels. "Book Now" "Menu" "Location" "Contact Us" "Promotions" "Hours" — customers should know exactly what each button does.
- Design it visually. Use your brand colors. Avoid text-only buttons. The rich menu is basically the homepage of your LINE account.
- Link buttons to actions. Each button can open a URL, send a keyword that triggers an auto-reply, or open a LINE LIFF app. A restaurant might link "Menu" to a PDF, "Book" to a reservation form, and "Deals" to the latest promotion.
Rich menu sizes:
- Large: 2500 x 1686 pixels (up to 6 buttons in a 3x2 grid)
- Small: 2500 x 843 pixels (up to 3 buttons in a 3x1 row)
Pro tip: Change your rich menu seasonally or for promotions. A hotel might swap to a Songkran-themed menu in April with a "Songkran Special" button. A restaurant can feature a "New Year Set Menu" button in December. LINE lets you schedule menu changes in advance.
Broadcast Messages vs 1:1 Chat
These are two fundamentally different tools, and using them wrong wastes money.
Broadcast messages go to all your followers (or a targeted segment) at once. Use them for:
- Weekly or monthly promotions
- New product or menu announcements
- Event invitations
- Seasonal greetings
- Loyalty program updates
1:1 chat is a private conversation between your business and one customer. Use it for:
- Answering customer questions
- Taking bookings and reservations
- Handling complaints
- Following up on purchases
- Sending personalized offers
The cost difference matters. Broadcasts count against your monthly message limit. If you are on the Free plan and send a broadcast to 250 followers, you have already exceeded your 200-message limit. 1:1 replies are always free, no matter what plan you are on.
Best practice: Use broadcasts sparingly and make every one count. A spa sending weekly promotions with a clear discount code will see 20-30% redemption rates on LINE — try getting that with email. But blasting daily messages will get you blocked fast.
7 Ways to Grow Your LINE Followers
Your LINE account is only as powerful as your follower count. Here is how to build it:
1. QR codes everywhere Print QR codes on your receipt, menu, table tent, front desk, shopping bags, and business cards. Every physical touchpoint is a chance to gain a follower. A hotel in Hua Hin added QR codes to room key holders and gained 300 followers in one month.
2. Add-friend promotions Offer something in exchange for following. "Add us on LINE, get 10% off your next visit." "Follow our LINE for a free dessert." This is the fastest way to grow. Make the offer visible — a sign at the register, a popup on your website, a pinned post on Facebook.
3. Website LINE button Add a LINE Add Friend button to your website header, contact page, and checkout flow. Use the official LINE button design so people recognize it instantly.
4. Facebook and Instagram cross-promotion Post your LINE QR code on social media. Run a Facebook ad that sends people to your LINE account instead of your website. The cost per follower is often lower than the cost per website click, and a LINE follower is far more valuable long-term.
5. LINE Ads (paid) LINE has its own ad platform. You can run ads that show up in LINE Timeline, LINE Today, and LINE Wallet. The "Add Friend" ad format is specifically designed to grow your follower count. Costs start around ฿3-5 per new follower.
6. Shopee and Lazada inserts If you sell online, include a card in every package with your LINE QR code and a reason to follow. "Follow us on LINE for exclusive deals and order tracking." E-commerce sellers report 15-25% scan rates from package inserts.
7. Group chat referrals Create a VIP LINE group for your best customers. They will naturally invite friends. A restaurant in Bangkok created a "Lunch Crew" group that grew from 20 to 200 members organically. Each member spends 40% more than average customers.
Auto-Reply vs AI Chatbot: The Difference
LINE OA comes with built-in auto-reply. It is free and works out of the box. But there is a massive gap between auto-reply and an actual AI chatbot.
LINE OA Auto-Reply:
- Matches exact keywords only
- Customer types "price" and gets the price list
- Customer types "how much is a massage" and gets nothing — the keyword did not match
- No memory of previous messages
- Cannot handle follow-up questions
- Feels robotic and frustrating
AI Chatbot (like ThaiBot):
- Understands natural language and intent
- Customer types "how much is a massage," "what are your prices," or "is it expensive" — all get the right answer
- Remembers context within a conversation
- Handles follow-up questions naturally
- Speaks Thai and English fluently
- Can make bookings, check availability, and recommend services
- Escalates to your team when needed
Here is a real example. A customer messages a spa:
With auto-reply: Customer: "I want a Thai massage for two people this Saturday afternoon" Bot: "Sorry, I don't understand. Please type 'menu' for our services."
With ThaiBot: Customer: "I want a Thai massage for two people this Saturday afternoon" Tawan: "We have availability this Saturday at 2 PM and 4 PM for a couples Thai massage. Each session is 60 minutes at ฿500 per person. Which time works better for you?"
The difference is night and day. Auto-reply handles maybe 30% of customer messages. An AI chatbot handles 80-90% and actually converts those conversations into bookings and sales.

LINE Messaging Best Practices
Getting followers is step one. Keeping them engaged without getting blocked is the real game.
Message frequency: Send 1-2 broadcast messages per week maximum. More than that and your block rate will spike. Thai consumers are quick to block accounts that spam.
Timing: The best times to send broadcasts in Thailand are 11:30-12:30 (lunch break) and 19:00-21:00 (evening). Avoid early morning and late night. For restaurants, send lunch promotions at 10:30 AM — right when people start thinking about where to eat.
Content mix: Follow the 80/20 rule. 80% of your messages should be useful or entertaining (tips, behind-the-scenes content, helpful information). 20% can be direct promotions. A clinic might send health tips four times and a treatment promotion once.
Personalization: Use audience segments on Light and Standard plans. Send spa promotions to customers who have visited your spa, not your restaurant guests. Send birthday greetings with a discount code. Targeted messages get 2-3x higher engagement than generic broadcasts.
Message format: Use rich messages (image + text + button) instead of plain text. They get significantly higher click-through rates. LINE also supports card carousel messages — perfect for showing multiple products or services with individual booking buttons.
Language: If you serve international tourists, send messages in both Thai and English. Or better yet, use a chatbot like ThaiBot that detects the customer's language automatically and responds accordingly.
Measuring Results: Key Metrics
You cannot improve what you do not measure. Here are the metrics that actually matter for LINE marketing:
Follower count and growth rate Track how many new followers you gain per week. A healthy LINE account grows 5-15% per month. If growth stalls, revisit your add-friend promotions.
Block rate The percentage of followers who block your account. Keep this under 5%. If it is climbing, you are sending too many messages or your content is not relevant. Industry average in Thailand is around 3-4%.
Message open rate LINE broadcast open rates in Thailand average 60-70%. That is 3x higher than email. If your open rate drops below 50%, your send timing or content needs work.
Click-through rate (CTR) For rich messages with buttons or links, a good CTR is 8-15%. Plain text with a URL gets 2-5%. Always use rich messages for anything with a call to action.
Reply rate What percentage of broadcasts trigger a customer reply. This indicates genuine engagement, not just passive viewing. A 5-10% reply rate is solid for promotional broadcasts.
Conversion tracking The hardest metric but the most important. Track how many LINE conversations turn into bookings, purchases, or store visits. If you use coupon codes exclusive to LINE, this is easy to measure. A hotel running a LINE-only room promotion can track exactly how many bookings came from the channel.
Cost per message On paid plans, calculate your cost per delivered message. On the Light plan at ฿1,200/month with 5,000 messages, that is ฿0.24 per message. Compare that to SMS at ฿1-2 per message. LINE is dramatically cheaper.
Common Mistakes to Avoid
Even experienced marketers make these errors on LINE. Skip them and save yourself months of frustration.
Broadcasting too often. The number one reason followers block accounts. Start with once a week and increase only if engagement stays high.
Ignoring 1:1 messages. Some businesses set up auto-reply and forget about the chat inbox. Customers who message you directly are your hottest leads. If you cannot reply fast enough, use an AI chatbot to handle the volume.
No rich menu. Running a LINE OA without a rich menu is like running a website without navigation. Set it up on day one.
Generic content. Do not just post what you already post on Facebook. LINE is a personal channel. Messages should feel like they are coming from a friend, not a billboard.
Not collecting data. LINE gives you basic follower demographics. Use audience tags and segments to learn who your followers are. A spa discovered that 70% of their LINE followers were women aged 25-34, so they tailored their promotions accordingly and doubled their redemption rate.
Ignoring the Messaging API. Once you are on the Light or Standard plan, the Messaging API unlocks powerful automation. You can build custom flows, integrate with your booking system, and connect tools like ThaiBot for AI-powered conversations. See our pricing guide for what automation costs across different platforms.
FAQ
How much does a LINE Official Account cost?
A basic LINE OA is free and includes 200 messages per month, 1:1 chat, auto-reply, and a rich menu. The Light plan costs ฿1,200/month for 5,000 messages with audience targeting. The Standard plan costs ฿4,000/month for 30,000 messages. Reply messages are free on all plans.
Can I use LINE OA for free forever?
Yes. The Free plan has no time limit. As long as you stay under 200 broadcast messages per month, you pay nothing. Most small businesses with fewer than 200 followers can operate on the Free plan indefinitely. You only need to upgrade when your follower count and broadcast volume grow.
What is the difference between LINE OA auto-reply and an AI chatbot?
LINE OA auto-reply matches exact keywords. It works for simple, predictable questions but fails when customers phrase things differently. An AI chatbot like ThaiBot understands natural language, handles follow-up questions, remembers conversation context, and can actually perform actions like making bookings. Think of auto-reply as a vending machine and an AI chatbot as a trained staff member.
How do I get more LINE followers quickly?
The fastest method is an add-friend promotion — offer a discount or freebie for following your LINE account. Combine this with QR codes at every customer touchpoint (receipts, tables, packaging, storefront). Businesses that run add-friend promotions typically gain 50-100 new followers per week depending on foot traffic.
Should I use LINE or Facebook for my business?
Both, but for different purposes. Facebook is for discovery — new customers find you through search, ads, and shared posts. LINE is for retention — once someone follows you, you have a direct communication channel with 60-70% open rates compared to 5-10% organic reach on Facebook. The winning strategy is to use Facebook to attract customers and LINE to keep them coming back.
Can I connect ThaiBot to my LINE Official Account?
Yes. ThaiBot connects directly to your LINE OA through the Messaging API (available on Light and Standard plans). Once connected, Tawan — ThaiBot's AI agent — handles customer messages automatically in Thai and English. She answers questions, makes bookings, and escalates complex issues to your team. Setup takes under 10 minutes. ThaiBot offers a Free plan, with Starter at ฿1,490/month and Pro at ฿3,990/month.
