Thai greeting and reply conventions for hotel messaging

A Thai-language reply from a hotel should follow a predictable opening-body-closing shape. Skipping the opening or closing reads as curt; over-decorating it reads as machine-translated.

Opening line

Standard openers, in order of warmth:

• สวัสดีค่ะ คุณ[Name] — "Hello, [Name]." Neutral, works for any first contact.
• ขอบคุณที่ติดต่อ[Hotel Name]ค่ะ — "Thank you for contacting [Hotel]." Use when the guest has just initiated the inquiry; pairs naturally with สวัสดีค่ะ on its own line.
• ขอบคุณสำหรับข้อความค่ะ — "Thank you for your message." Lighter version, good for follow-up replies in a thread.

For LINE, a single opener line is enough. For WhatsApp or email, the two-line variant (greeting + thank-you) feels more appropriate.

Body

Keep paragraphs short — 1–3 sentences each, separated by blank lines. Thai script without line breaks becomes a wall of text very quickly because there are no inter-word spaces. Blank lines between thoughts are not optional; they are the only visual structure.

When listing things (rates, room types, dates), use bullet points or numbered lines. Do not run them into a sentence.

Example structure:

```
สวัสดีค่ะ คุณสมชาย

ขอบคุณที่ติดต่อ[Hotel] ค่ะ ทางโรงแรมยังมีห้องว่างสำหรับวันที่ 12-15 ก.ค. ค่ะ

• Deluxe Sea View: 4,800 บาท/คืน (รวมอาหารเช้า, รวม VAT)
• Junior Suite: 7,200 บาท/คืน (รวมอาหารเช้า, รวม VAT)

หากสนใจสำรองห้อง รบกวนแจ้งจำนวนผู้เข้าพักและประเภทห้องที่ต้องการนะคะ
```

Closing line

Standard closers:

• ขอบคุณค่ะ — "Thank you." The minimum.
• หากมีข้อสงสัยเพิ่มเติม สามารถสอบถามได้ตลอดเวลานะคะ — "If you have further questions, please feel free to ask at any time." Warm, appropriate when the inquiry isn't fully resolved.
• ขอบคุณค่ะ / [Hotel Name] — sign-off with the hotel name on its own line for formal threads.

Avoid signing replies with a personal name unless the conversation has already become personal. The reply should feel like it comes from "the hotel," not from a specific staff member, until the guest establishes a relationship.

What to avoid

• Excessive emoji and stickers in the first reply. LINE supports them, but the opening message should establish professionalism first.
• Mixing English mid-sentence ("ขอบคุณ for your inquiry ค่ะ") — pick a language and stay in it.
• Pasting prices without baht symbol or currency. Always: 4,800 บาท/คืน or THB 4,800/night, never bare numbers.
