You know what to say to customers in person. The smile, the wai, the "welcome back, same table?" That warmth disappears the moment you open LINE and stare at a blank message box.
Most Thai businesses send one of two things on LINE: nothing, or a generic blast that gets muted. Neither builds loyalty. Neither drives repeat visits.
These 9 templates fix that. Each one is written for real Thai business scenarios — restaurants, hotels, spas, clinics, and salons. Copy the Thai text directly into LINE. Adjust the bracketed details. Send.
Why Templates Matter
LINE is the most-used messaging app in Thailand with over 54 million active users. Your customers are already there. The question is not whether to message them — it is what to say and when.
Businesses that send personalized, well-timed messages on LINE see 3 to 5 times higher response rates than those sending generic broadcasts. But most owners do not have time to craft individual messages. Templates give you the structure. You add the personal touch.
Good templates share three traits:
- They feel personal. The customer's name, their last visit, what they ordered.
- They have a clear purpose. One message, one action.
- They respect the customer's time. Short, warm, direct.
Here are 9 templates that hit all three. For a deeper look at LINE marketing strategy, read our complete LINE marketing guide.
Template 1: Welcome / Greeting New Follower
When to send: Immediately after someone adds your LINE OA as a friend.
Best for: Restaurants, hotels, spas, salons, clinics — any business using LINE OA.
Thai message:
สวัสดีค่ะ ยินดีต้อนรับสู่ [ชื่อร้าน] 🙏
ขอบคุณที่เพิ่มเราเป็นเพื่อนนะคะ เรายินดีให้บริการค่ะ
ส่งข้อความหาเราได้ตลอด ไม่ว่าจะสอบถามข้อมูล จองคิว หรือดูโปรโมชั่นล่าสุด
เพื่อขอบคุณที่ติดตาม รับส่วนลด [10%] สำหรับครั้งแรกที่มาใช้บริการค่ะ ❤️
English translation:
Hello and welcome to [Business Name] 🙏
Thank you for adding us as a friend. We are happy to help.
Message us anytime — whether you have questions, want to book, or want to see our latest promotions.
As a thank you for following, enjoy [10%] off your first visit ❤️
Why it works: First impressions set the tone. This message is warm, sets expectations for what the LINE channel offers, and gives an immediate incentive to visit. The discount converts followers into paying customers — studies show welcome offers increase first-visit rates by up to 40%.
Template 2: Booking Confirmation
When to send: Immediately after a booking is made (automated or manual).
Best for: Hotels, spas, restaurants with reservations, clinics, salons.
Thai message:
ยืนยันการจองค่ะ ✅
คุณ [ชื่อลูกค้า] จองสำเร็จแล้วนะคะ
📅 วันที่: [วัน/เดือน/ปี] 🕐 เวลา: [เวลา] 📍 สถานที่: [ชื่อร้าน + สาขา] 🔖 บริการ: [รายละเอียดบริการ/ห้อง/โต๊ะ]
หากต้องการเปลี่ยนแปลงหรือยกเลิก กรุณาแจ้งล่วงหน้าอย่างน้อย [2] ชั่วโมงนะคะ
รอต้อนรับคุณค่ะ 😊
English translation:
Booking confirmed ✅
[Customer Name], your reservation is all set.
📅 Date: [DD/MM/YYYY] 🕐 Time: [Time] 📍 Location: [Business Name + Branch] 🔖 Service: [Service details / Room / Table]
If you need to change or cancel, please let us know at least [2] hours in advance.
We look forward to welcoming you 😊
Why it works: Confirmation messages reduce no-shows by up to 30%. They also eliminate the "did my booking go through?" anxiety. The clear formatting makes it easy for customers to screenshot or save the details, and the cancellation policy reminder protects your business.
Template 3: Appointment Reminder (24 Hours Before)
When to send: 24 hours before the scheduled appointment or reservation.
Best for: Spas, clinics, salons, restaurants with fixed reservations, hotels (check-in reminder).
Thai message:
แจ้งเตือนนัดหมายค่ะ 🔔
คุณ [ชื่อลูกค้า] มีนัดกับ [ชื่อร้าน] พรุ่งนี้นะคะ
📅 วัน: [วัน/เดือน/ปี] 🕐 เวลา: [เวลา] 🔖 บริการ: [รายละเอียด]
📌 เตรียมตัว: [ข้อมูลที่เป็นประโยชน์ เช่น มาก่อนเวลา 15 นาที / จอดรถฟรี / นำบัตรประชาชนมาด้วย]
ยืนยันหรือเปลี่ยนแปลง แจ้งได้เลยค่ะ 😊
English translation:
Appointment reminder 🔔
[Customer Name], you have an appointment with [Business Name] tomorrow.
📅 Date: [DD/MM/YYYY] 🕐 Time: [Time] 🔖 Service: [Details]
📌 Preparation: [Helpful info, e.g., arrive 15 minutes early / free parking / bring your ID]
To confirm or make changes, just reply here 😊
Why it works: The 24-hour window is the sweet spot. It is far enough out that the customer can reschedule without wasting your slot, but close enough that the appointment stays top of mind. The preparation tips show you care about their experience — not just their money.
Template 4: Promotion / Special Offer
When to send: When launching a new promotion, seasonal offer, or limited-time deal. Best sent between 10 AM and 12 PM or 5 PM and 7 PM for highest open rates.
Best for: Restaurants, spas, hotels, retail shops, salons.
Thai message:
โปรพิเศษสำหรับเพื่อน LINE ค่ะ 🎉
[ชื่อโปรโมชั่น]
🔥 [รายละเอียดข้อเสนอ เช่น ลด 20% ทุกเมนู / นวดไทย 1 ชม. เหลือ 399 บาท / อยู่ 2 คืน จ่าย 1 คืน]
📅 ตั้งแต่วันนี้ถึง [วันหมดเขต] 📍 ที่ [ชื่อร้าน + สาขา]
จองเลย หรือสอบถามเพิ่มเติมแชทหาเราได้เลยค่ะ
[ลิงก์จอง / เบอร์โทร]
English translation:
Special offer for LINE friends 🎉
[Promotion Name]
🔥 [Offer details, e.g., 20% off all menu items / 1-hour Thai massage only 399 baht / stay 2 nights pay for 1]
📅 Available from now until [Expiry Date] 📍 At [Business Name + Branch]
Book now, or message us for more details.
[Booking link / Phone number]
Why it works: The "LINE friends" framing makes followers feel they are getting an exclusive deal — not a mass advertisement. A clear expiry date creates urgency. One specific offer outperforms a list of five. Keep it focused on one action: book.
Template 5: Post-Visit Thank You
When to send: 1 to 2 hours after the customer's visit or checkout.
Best for: Spas, restaurants, hotels, clinics, salons.
Thai message:
ขอบคุณที่มาใช้บริการค่ะ คุณ [ชื่อลูกค้า] 🙏
หวังว่าจะชอบ [บริการ/เมนู/ห้อง] นะคะ ทีมงานดีใจที่ได้ต้อนรับคุณค่ะ
มีอะไรแนะนำหรือติชม บอกเราได้เลยนะคะ ทุกความคิดเห็นช่วยให้เราดีขึ้นค่ะ
หวังว่าจะได้เจอกันอีกเร็วๆ นี้ค่ะ 💚
English translation:
Thank you for visiting, [Customer Name] 🙏
We hope you enjoyed the [service/dish/room]. Our team was happy to welcome you.
If you have any feedback or suggestions, please let us know. Every comment helps us improve.
We hope to see you again soon 💚
Why it works: A thank-you within 2 hours catches the customer while the experience is fresh. It feels genuine, not automated. The open-ended feedback invitation catches complaints early — before they become Google reviews. The green heart matches LINE's brand color, a subtle touch that reinforces the channel.
Template 6: Review Request
When to send: 24 to 48 hours after the visit. Only send to customers who had a positive interaction.
Best for: Restaurants, hotels, spas, clinics — any business where Google or Facebook reviews drive new customers.
Thai message:
สวัสดีค่ะ คุณ [ชื่อลูกค้า] 😊
หวังว่ายังประทับใจกับ [ชื่อร้าน] นะคะ
ถ้าไม่รบกวนมากเกินไป ช่วยเขียนรีวิวสั้นๆ ให้เราได้ไหมคะ รีวิวของคุณช่วยให้คนอื่นตัดสินใจได้ และมีความหมายกับทีมงานมากค่ะ
👉 [ลิงก์ Google Review]
ขอบคุณล่วงหน้าค่ะ 🙏
English translation:
Hello, [Customer Name] 😊
We hope you still have good memories from [Business Name].
If it is not too much trouble, could you write a short review for us? Your review helps others decide, and it means a lot to our team.
👉 [Google Review Link]
Thank you in advance 🙏
Why it works: The 24 to 48 hour window balances urgency with politeness — you are not asking the second they walk out, but you are asking before the memory fades. The phrase "if it is not too much trouble" is culturally appropriate in Thailand and shows respect. One direct link removes friction. Businesses that actively request reviews get 3 to 5 times more than those that wait passively.
Template 7: Re-engagement (Haven't Visited in 30 Days)
When to send: 30 days after a customer's last visit or purchase.
Best for: Restaurants, spas, salons, clinics, retail stores — businesses that rely on repeat customers.
Thai message:
คิดถึงคุณค่ะ คุณ [ชื่อลูกค้า] 💚
ไม่ได้เจอกัน [30] วันแล้ว หวังว่าสบายดีนะคะ
อยากเชิญคุณกลับมาเยี่ยมเราอีกครั้ง มีเมนู/บริการใหม่ที่คิดว่าคุณน่าจะชอบค่ะ
🎁 แสดงข้อความนี้ รับ [ส่วนลด 15% / ของแถม / อัพเกรดฟรี] เลยค่ะ
หมดเขต [วัน/เดือน/ปี] นะคะ รอต้อนรับค่ะ 🙏
English translation:
We miss you, [Customer Name] 💚
It has been [30] days since your last visit. We hope you are doing well.
We would love to welcome you back. We have new menu items / services we think you will enjoy.
🎁 Show this message to receive [15% off / a free extra / a complimentary upgrade].
Valid until [DD/MM/YYYY]. We look forward to seeing you 🙏
Why it works: Thirty days is the point where you risk losing a customer for good. The "show this message" mechanic is brilliant for LINE — it gives the customer a tangible reason to come back, and your staff can easily verify it. The tone is warm, not pushy. You are saying "we noticed you" without saying "you stopped spending money here." For more on writing messages that drive action, check our guide on how to write LINE messages that get replies.
Template 8: Holiday Greeting
When to send: Major Thai holidays — Songkran, Loy Krathong, New Year, Chinese New Year, Mother's Day, Father's Day. Send on the morning of the holiday or the evening before.
Best for: All business types. This is a brand-building message, not a sales push.
Thai message:
สุขสันต์วัน[ชื่อวันหยุด]ค่ะ 🎊
ในโอกาสพิเศษนี้ ทีมงาน [ชื่อร้าน] ขออวยพรให้คุณและครอบครัวมีความสุข สุขภาพแข็งแรง และสมหวังทุกประการค่ะ
ขอบคุณที่เป็นส่วนหนึ่งของครอบครัว [ชื่อร้าน] มาตลอดนะคะ 🙏
ช่วงเทศกาลนี้เราเปิดให้บริการ [ปกติ/วันที่ปิด/เวลาพิเศษ] ค่ะ
ด้วยรักจากทีม [ชื่อร้าน] 💚
English translation:
Happy [Holiday Name] 🎊
On this special occasion, the [Business Name] team wishes you and your family happiness, good health, and success in everything.
Thank you for being part of the [Business Name] family all this time 🙏
During this holiday period, we are [open as usual / closed on these dates / operating at special hours].
With love from the [Business Name] team 💚
Why it works: Holiday messages build emotional connection without asking for anything. They remind customers you exist — right when they are off work and more likely to book a spa visit, plan a dinner, or take a trip. Including your holiday hours is a practical detail that prevents wasted trips and shows you think ahead.
Template 9: Menu / Service Update
When to send: When launching new menu items, services, seasonal specials, or significant changes to your offerings.
Best for: Restaurants (new menu items), spas (new treatments), hotels (new packages), salons (new services).
Thai message:
มีอะไรใหม่ที่ [ชื่อร้าน] ค่ะ ✨
เรามี [เมนูใหม่ / บริการใหม่ / แพ็คเกจใหม่] มานำเสนอค่ะ
🆕 [รายการที่ 1] — [ราคา] 🆕 [รายการที่ 2] — [ราคา] 🆕 [รายการที่ 3] — [ราคา]
[ประโยคอธิบายสั้นๆ เช่น ใช้วัตถุดิบท้องถิ่นคัดพิเศษ / เทคนิคใหม่จากเกาหลี / แพ็คเกจสุดคุ้มสำหรับคู่รัก]
อยากลองไหมคะ จองหรือสอบถามเพิ่มเติมแชทมาได้เลยค่ะ 😊
English translation:
Something new at [Business Name] ✨
We are excited to introduce our [new menu items / new services / new packages].
🆕 [Item 1] — [Price] 🆕 [Item 2] — [Price] 🆕 [Item 3] — [Price]
[Short description, e.g., made with locally sourced premium ingredients / new techniques from Korea / a special couples package]
Want to try it? Book or ask us anything right here 😊
Why it works: Updates keep your LINE channel interesting. If you only send promotions, customers mute you. New offerings give them a reason to pay attention and visit. Limiting to three items prevents overwhelm. The short description adds context and desire without turning the message into a menu PDF.
How to Customize for Your Business
These templates work as-is, but they perform better when you add your brand's voice. Here is how:
Match your tone. A luxury hotel should sound refined and polished. A neighborhood somtam shop should sound friendly and casual. Read the templates aloud in Thai — if it does not sound like your staff would say it, adjust the language.
Use real details. Replace every bracket with actual information. "[ส่วนลด 10%]" becomes "ลด 10% ทุกเมนูข้าวแกง". "[บริการ]" becomes "นวดน้ำมันอโรมา 90 นาที". Specificity builds trust.
Time it right. The "when to send" guidance matters. A promotional message at 7 AM annoys people. The same message at 11:30 AM — when they are thinking about lunch — gets tapped.
Segment your audience. Not every customer should get every message. First-time visitors get the welcome template. Regulars get the re-engagement template. High spenders get exclusive offers. LINE OA lets you tag and segment followers.
Test and iterate. Send Template A to half your audience and a variation to the other half. Track which version gets more responses, bookings, or visits. Small changes in wording can double response rates.

How AI Personalizes at Scale
Templates get you started. But real personalization — the kind where a customer feels like you actually remember them — is hard to do manually when you have hundreds of LINE followers.
This is where AI changes the game.
ThaiBot's customer support agent, Tawan, can send each of these templates automatically at exactly the right time, customized for each customer. When someone adds your LINE, Tawan sends the welcome message immediately. When a booking is made, the confirmation goes out in seconds. Twenty-four hours before the appointment, the reminder fires. After checkout, the thank you. Thirty days of silence, the re-engagement offer.
But Tawan goes beyond templates. She reads the conversation, remembers what the customer ordered last time, knows they prefer evening appointments, and adjusts the message accordingly. "คุณสมชาย ครั้งที่แล้วนวดหลังชอบมากเลยใช่ไหมคะ" — that is not a template. That is AI that understands your customer.
The result: messages that feel handwritten but scale to thousands of customers. No staff time. No forgotten follow-ups. No midnight messages going unanswered.
Frequently Asked Questions
Can I copy these templates directly into LINE OA? Yes. Copy the Thai text, replace the bracketed sections with your business details, and send. They work with LINE OA broadcasts, auto-reply, and Flex Messages.
How often should I send messages on LINE? For promotional messages, once or twice per week maximum. Transactional messages (confirmations, reminders) should be sent whenever they are triggered. Over-messaging is the number one reason followers mute your account.
Should I include images or just text? Both work, but rich messages (image + text) get 20 to 30% higher engagement on LINE. Use a clean product photo or a simple graphic — not a cluttered flyer with seven promotions. Keep the image focused on one thing.
What is the best time to send LINE messages in Thailand? For promotions and updates: 10 AM to 12 PM (lunch decision time) or 5 PM to 7 PM (evening planning). Avoid early morning, late night, and Monday mornings. For transactional messages like confirmations and reminders, send them when they are relevant regardless of time.
Can I automate these messages? Yes. LINE OA has basic automation for welcome messages and keyword triggers. For full automation — personalized timing, customer segmentation, multi-step sequences — you need an AI tool. ThaiBot automates all 9 of these templates with personalization built in.
Do these templates work for English-speaking customers? They do. If you serve both Thai and international customers, you need bilingual messaging. The English translations above are ready to use. An AI chatbot like Tawan automatically detects the customer's language and responds accordingly — Thai message to Thai customers, English to English speakers, without you lifting a finger.
