英文專業email的格式是什麼?
英文專業email有六個部分,整封信剛好放得進一個手機螢幕:三、四個字的主旨、帶對方姓名的問候、一句說明你為什麼寫信、兩三個短句交代細節、一個附日期的請求,以及結尾敬語。以下是填好內容的六段式範例,共51個字,寄給一位還沒付款的客戶:
Subject: Invoice 2231 payment date
Dear Ms. Alvarez,
I am writing about invoice 2231, which was due on 12 September.
Our records show it is still open. The amount is 4,800 euros, and a copy is attached.
Could you confirm a payment date by Friday, 3 October?
Best regards, Lena Fischer
每一行都只做一件事。主旨寫出事情和需要的決定。說明來意的句子以 "I am writing about" 或 "Thanks for" 開頭,絕不拿天氣或健康當開場。請求只有一個問句,而且帶著日期,讓讀者知道要做什麼、何時要做。整封信連十二歲的孩子也看得懂,這正是重點。
這些回覆數據來自 Boomerang 2016年的分析,樣本是用戶請它追蹤回覆的4000萬多封email。原文寫道:"Emails written at a 3rd grade reading level were optimal." 這類信比大學程度的寫法多36%的回覆,比高中程度多17%。同一份資料還發現,3到4個字的主旨獲得最多回應,而提出一到三個問題的email,比完全不提問的email多50%的機率得到回覆。每一個你沒把握的長字都讓你付出兩次代價:一次是花掉的時間,一次是降低的回覆率。
還有一個縮短篇幅的理由:Microsoft 在 2025年6月的 Work Trend Index 中,根據遙測數據發現一般員工每天收到117封email,"most of them skimmed in under 60 seconds"。你的email要和另外116封爭奪同一分鐘的注意力。
針對這個關鍵字的第一頁指南在結構上看法一致,卻只講到這裡。2026年9月27日排名的八篇文章(Talaera、engVid、Instructional Solutions、Speak Confident English、EF English Live、Break Into English、English Path 和 RewritePal)合計只有12個完整email範本,中位數每篇一個;EF 和 English Path 一個也沒有,八篇也沒有任何一篇點出來自特定母語的錯誤。下面的十個範本和十個修正,正是它們省略的部分。
如果英文是你的第二語言,讀者在書面文字裡幾乎注意不到口說時會聽出的口音。EF 2025年英語能力指標在123個國家測試了220萬名成人,全球平均488分;越南500分(第64名)、印度484分(第74名)、巴西482分(第75名)、日本446分(第96名)、墨西哥440分(第103名)、沙烏地阿拉伯404分(第115名)。同一版 EF 的結論是:"In over half of the countries measured, speaking is the weakest English skill." 寫作給你口說永遠沒有的三十秒思考時間,上面的六個部分正是用來善用這段時間。
英文專業email該有多正式?
英文專業email的禮貌程度比口語高一級,比法律信函低兩級:寫 "Could you send it by Friday?" 而不是 "Can you send it",也絕不寫 "I would be most grateful if you could kindly send it"。非母語人士出錯,往往是太正式而不是太隨便,因為學校英文教的是書信語氣,而職場email早在多年前就不再使用。下表是同樣六個部分的三種程度,適用於2026年9月時寄給美國或英國商務聯絡人的第一封email。
| 部分 | 太正式 | 多數職場email適用 | 太隨便 |
|---|---|---|---|
| 問候 | "Dear Sir or Madam," / "Respected Madam," | 第一次聯絡用 "Dear Ms. Alvarez,",之後用 "Hi Priya," | "Hey!" / "Hiya" / 沒有問候 |
| 開頭句 | "I hope this email finds you in the best of health." | "Thanks for your message yesterday." / "I am writing about the March invoice." | "Quick one" / "Sup" |
| 請求 | "I would be most grateful if you could kindly arrange to send..." | "Could you send the signed copy by Friday?" | "Send it over asap pls" |
| 壞消息 | "We regret to inform you that we are unable to accommodate your request." | "We cannot move the date, because the venue is booked that week." | "Yeah that's not gonna work" |
| 結尾句 | "Awaiting your kind response at your earliest convenience." | "I look forward to your reply." / "Let me know if Thursday works." | "Cheers, ttyl" |
| 結尾敬語 | "Yours faithfully," | "Best regards," / "Kind regards," | "Thx" / "xx" |
有兩條規則決定程度。第一次聯絡時,比你以為對方期待的再正式一級:"Dear Ms. Alvarez" 不花你任何成本,而德國、日本或韓國的讀者會把陌生人的 "Hi" 當成草率。對方回信之後,就配合你收到的上一封信的語氣。如果對方簽名是 "Best, Tom",你就簽 "Best, Lena"。中間那一欄是美國或英國同事寫給另一位同事的寫法,在所有英語系國家的辦公室都很安全。
正式和有禮貌是兩回事。"Kindly revert at the earliest" 很正式,讀起來卻像命令;"Could you reply by Wednesday?" 很直白,讀起來反而有禮貌。英文的禮貌在於問句形式和日期,而如何軟化一則訊息示範了五個既增添溫度又不拿掉請求的做法。
英文專業email該怎麼結尾署名?
用 "Best regards," 或 "Kind regards," 收尾,後面接你的全名;這兩句幾乎涵蓋所有英語系國家的職場email。"Best regards" 是美國的預設寫法,"Kind regards" 是英國的,兩者在各地都看得懂。
其他寫法的用途比較窄。"Sincerely," 是美式正式信件、求職信和寄給資深人士的第一封email的結尾。"Yours sincerely," 和 "Yours faithfully," 屬於英式書信:用了對方姓名就寫 sincerely,寫 "Dear Sir or Madam" 就寫 faithfully,兩者放在回信串裡都顯得生硬。對方幫了你的忙時可以用 "Thanks,",彼此已經直呼名字之後可以用 "Best,"。"Cheers," 在英國和澳洲熟人之間沒問題,在美國則顯得奇怪。避開 "Thanks in advance",它等於告訴讀者你已經認定他們會答應;也避開單獨一個 "Regards",它是這一組裡最冷淡的。
署名下面寫全名,下一行寫職稱和公司,想接電話的話再加電話號碼。普渡大學線上寫作實驗室在email 禮儀頁面向學生教授這些,並補充了非母語人士最常往另一個方向犯的規則:"Use standard spelling, punctuation, and capitalization." 全部大寫的署名,或小寫的姓名,會比內容先被讀者注意到。
非母語人士最常犯的十個錯誤與修正
下面的十個錯誤,不是從母語直譯而來,就是在某一地區英文中很標準、換到別處卻顯得奇怪或太強硬的用語。其中三個("please revert"、"do the needful"、"I have a doubt")在印度英語中是正確的,只有在寄給北美、歐洲或澳洲的讀者時才需要修改。這十個都不是拼字錯誤,所以拼字檢查工具會把它們全部放過。
| 草稿的寫法 | 為什麼收件人讀起來不對 | 改寫成 |
|---|---|---|
| "Dear Mr. John," / "Dear Sir Ahmed," | 頭銜要搭配姓氏,不能搭配名字 | "Dear Mr. Rahman," 或 "Hi John," |
| "Respected Sir," / "Greetings of the day!" | 來自印度和中東學校英文的正式開頭,美國或英國的辦公室沒人使用 | "Dear Ms. Alvarez," / "Hello Priya," |
| "Please revert" / "revert back" | 在印度以外,revert 的意思是回到先前的狀態,讀者會停下來疑惑 | "Please reply by Friday" |
| "Kindly do the needful" | 讀者不知道 the needful 指什麼,而 "kindly" 加命令讀起來像指令 | 寫明動作:"Please approve the invoice by Friday" |
| "informations" / "advices" / "feedbacks" | 英文的 information、advice 和 feedback 是不可數名詞;用複數一個字就暴露你是學習者 | "information"、"a piece of advice"、"your feedback" |
| "I am waiting since three days" | since 後面接時間點;for 後面接一段時間;而且現在進行式聽起來不耐煩 | "I have been waiting for three days",或更好的寫法 "I sent this on Monday" |
| "discuss about the plan" / "explain me the process" | discuss 直接接受詞;explain 要接 "to me" | "discuss the plan" / "explain the process to me" |
| "Please send report" / "I attach the Contract" | 缺少冠詞,常見於俄語、波蘭語、日語、中文和韓語使用者,以及來自德語的名詞大寫 | "Please send the report" / "I have attached the contract" |
| "Waiting for your reply." / "Reply ASAP." | 讀起來像陌生人的最後通牒 | "I look forward to your reply." / "Could you reply by Wednesday?" |
| "Hope you are doing well. I am fine." / "According to me" | 前者是沒人會回答的問候;後者意思是「依我看」,卻像在引用自己的話 | 刪掉健康問候;改用 "In my view" 或 "I think" |
其中兩個值得查字典。Wiktionary 把 revert 的「回覆」義項標為 "(originally India, now global)",這正是問題所在:在印度和新加坡學英文的人之間是全球通用,但對俄亥俄州的讀者卻很陌生,他會以為你要他撤銷某件事。而 information 被列為通常不可數,所以 "some information" 和 "two pieces of information" 是對的,"two informations" 則是英文email裡最可靠的法語、德語或西班牙語母語者的標誌。
十個錯誤的修正方法是同一個習慣:寫完草稿後,以收件人的身分讀一遍,想像他不會說你的語言,也從沒見過你。任何你不會在茶水間對同事開口說的話,都刪掉。最後一節的 AI 提示詞會幫你做這一輪檢查,而且它抓得到這十個,因為它們是固定的模式,不是打字錯誤。
十個60字以內的專業email範本
下面每個範本都依照六個部分,不到60個字,只需要換掉方括號裡的字。主旨都是三、四個字,這正是 Boomerang 發現回覆最多的長度。直接寄出就好,簡單是刻意的。
1. 請求:
Subject: Signed NDA by Friday?
Hi Marta,
I am writing about the NDA we discussed on Tuesday. The signed copy is the last document we need before the kickoff on 6 October. Could you send it by Friday, 3 October?
Best regards, [Name]
2. 對方沒回覆時的跟進:
Subject: Following up: proposal
Hi Daniel,
I sent the proposal on 22 September and have not heard back, which is fine if you are busy. Is there anything you need from me to decide? If a call is easier, I am free Thursday afternoon.
Best regards, [Name]
3. 有禮貌地婉拒:
Subject: Speaking slot on 14 October
Dear Ms. Okafor,
Thank you for the invitation to speak on 14 October. I cannot take it, because I will be travelling that week. If a later date opens, I would be glad to hear about it.
Kind regards, [Name]
4. 為錯誤道歉:

Hi Tom,
The Q3 figures in Monday's report were wrong; the correct total is 48,200, not 42,800. The corrected version is attached. I am sorry for the confusion, and I have added a totals check so it does not happen again.
Best regards, [Name]
5. 請求延長時間:

Best regards, [Name]
6. 會議邀請:
Subject: 30 minutes on pricing?
Hi Priya,
Could we take 30 minutes next week to agree the pricing for the March launch? I am free Tuesday 10:00 to 12:00 and Thursday after 14:00, your time. If neither works, please suggest a slot.
Best regards, [Name]
7. 改期:
Subject: Moving Thursday's call

範本3只是整個系列的精簡版;如何禮貌地婉拒email還有十六個,每個都在50字以內。這裡每個範本的共同點是一個請求、一個日期、沒有形容詞,這也讓它們在你還在學的語言裡可以放心寄出:裡面沒有什麼會出錯的地方。
哪個 AI 提示詞能在不改變原意的前提下修改草稿?
有效的提示詞會先告訴模型哪些東西不能動,再說要修正什麼:保留每個事實、姓名、數字、日期和請求,不添加任何內容,然後才修正文法、冠詞、介系詞和語氣。如果沒有「保留我的原意」這條規則,模型在修正文法之外,往往會多加一句開場白和一句結尾的讚美,而提示詞最後要求的修改清單,就是你抓到這種情況的方法。把下面這段貼上,草稿放在它的下方。
```text
Rewrite the email below for a work reader in [country]. Keep every fact, name, number, date and request exactly as written. Do not add sentences, compliments or explanations, and do not change what I am asking for. Fix grammar, articles, prepositions, word choice and register. Use plain words, sentences under 20 words, and the tone of a polite colleague, not a lawyer. Keep it under [60] words. After the rewrite, list each change you made in one line each, so I can learn from it.
My draft:
[paste]
```
最後的修改清單,是讓你下個月進步的部分。當模型寫了十次 "changed 'since three days' to 'for three days'",你就不會再這樣寫了。另外,先讀清單,再讀改寫後的內容:如果有一行寫著 "added a friendly opening",代表模型違反了第一條規則,把那句刪掉。
接著在第二個模型裡做語氣檢查,這個模型沒看過你的指示,所以讀這封email的方式和收件人一樣。貼上改寫後的版本,然後問:
```text
You are the recipient of this email: a [role] in [country] who does not know me. Answer in three lines. How formal does it sound, 1 to 5? Does any sentence sound translated, stiff or rude? Is the request and its deadline clear? Then compare it with my original below and list anything whose meaning changed.
Rewrite:
[paste]
My original:
[paste]
```
第二個模型能抓到第一個抓不到的問題,因為改寫你草稿的模型,是依照拿到的指示在評自己的作品,而第二個模型評的只有這封信對讀者的效果。在 Whizi 上,這就是同一個畫面的兩欄,GPT 負責改寫,Claude 負責檢查;不過把兩者並排顯示的比較檢視從 Pro 方案開始提供,Starter 方案則在同一個對話串裡用 Claude Haiku 做檢查,而 Gmail 的 Help me write 在便利性上勝過任何聊天應用,因為它就在收件匣裡。AI 寫email則說明,當你不是從自己的草稿而是從零開始時,哪個模型寫得最好。
不論用哪些工具,判斷標準都一樣:寄出十二歲孩子也看得懂、而且仍然保有你的日期的那個版本。如果改寫後日期不見了,代表模型改善了你的英文,卻毀了你的email。
- 主旨用三、四個字,寫出事情和需要的決定
- 以姓名和一句來意開頭;刪掉任何關於健康或天氣的句子
- 只提一個請求,用問句形式,並附上日期
- 對照十個錯誤的表格檢查草稿,特別是 revert、do the needful、information 的複數和漏掉的冠詞
- 以 Best regards 或 Kind regards 加上全名收尾
- 執行「保留我的原意」提示詞,先讀修改清單,再用第二個模型檢查語氣
常見問題
英文專業email應該寫多長?
50到125個字之間。在 Boomerang 2016年對4000萬封追蹤email的分析中,這個範圍內的信有超過一半的機率得到回覆,而25個字和2000個字的email回覆率都降到約44%。本頁每個範本都在60字以內,在超過最佳範圍之前,還留有空間再多寫一句細節。
專業email裡還能用 "Dear Sir or Madam" 嗎?
只有在你真的找不到名字時才用,現在已經很少見。名字通常可以在公司網站、先前email的簽名檔或 LinkedIn 找到,而 "Dear Ms. Alvarez" 的效果比任何匿名問候都好。如果真的沒有名字,"Dear Hiring Team" 或 "Dear Customer Service Team" 讀起來比 "Dear Sir or Madam" 自然,而 "To whom it may concern" 應該留給推薦信。
可以用 AI 寫英文專業email嗎?
可以,安全的做法是自己先寫草稿,再讓模型修正,並指示它保留每個事實、日期和請求不變。如果讓模型從零開始寫email,會產生比你需要的更長、更熱情、更空泛的信,而讀者看得出來。本頁的提示詞會修正文法、冠詞和語氣,並列出每一項修改,再由第二個模型以收件人的角度檢查語氣。
