Business emails in English that sound natural

Email is still the backbone of professional communication, and in international business, most emails are written in English. Yet many professionals who speak English well feel insecure when writing emails. They worry about sounding rude, too informal or too stiff. Many learned an old-fashioned, very formal style at school, full of phrases like "I am writing to inform you" and "Please find attached herewith," which sound unnatural today. In this guide, I share how to write business emails that sound clear, friendly and professional, with structures, dozens of useful phrases and before-and-after examples from the kind of emails my students write every day.

The modern business email: principles

1. Get to the point quickly. Busy readers want to know what you need in the first lines.
2. Keep it short. If an email needs more than a few paragraphs, consider a call or an attached document.
3. Be polite but natural. Modern professional English is friendly and direct, not ceremonial.
4. Make requests clear. State exactly what you need and by when.
5. Use short paragraphs and bullet points for readability.
6. Write a specific subject line.
7. Proofread before sending.

The structure of a good email

Subject lines

A good subject line is specific and, if possible, includes the action and deadline.

• Weak: "Question" — Better: "Question about the March invoice"
• Weak: "Meeting" — Better: "Meeting request: pricing review next week"
• Weak: "Update" — Better: "Project Alpha: weekly update, May 12"
• Weak: "Urgent!!!" — Better: "Action needed today: client contract signature"

Greetings

Avoid "Dear Sir/Madam" when possible; it sounds dated. Try to find the person's name. Match the formality of the person who writes to you: if they write "Hi Achama," you can reply with "Hi Laura."

Opening lines

• "Thanks for your email."
• "Thank you for getting back to me so quickly."
• "I hope you're doing well."
• "It was great to meet you at the conference last week."
• "Following up on our call yesterday, …"
• "I'm reaching out because…"

Use "I hope you're doing well" occasionally, not in every email to the same person, or it becomes automatic.

Stating your purpose

• "I'm writing to ask about…"
• "Just a quick update on…"
• "I wanted to let you know that…"
• "I'd like to confirm the details of…"
• "I have a quick question about…"

Making requests

Polite requests in English use "could," "would" and "please."

Attachments and links

• "I've attached the updated proposal."
• "Please see the attached file for details."
• "Here's the link to the shared document."
• "Sorry, I forgot to attach the file. Here it is."

Avoid "Please find attached herewith." It is grammatically fine but sounds like a legal document from another century.

Following up

• "Just following up on my email from last week."
• "I wanted to check in on the status of…"
• "Have you had a chance to look at…?"
• "Gentle reminder that the deadline is tomorrow."

Apologizing and delivering bad news

• "Sorry for the late reply."
• "Thank you for your patience."
• "Unfortunately, we won't be able to deliver by Friday."
• "I'm afraid the price has increased due to…"
• "We apologize for any inconvenience this may cause."
• "To make up for the delay, we'd like to offer…"

Words like "unfortunately" and "I'm afraid" soften bad news. Offering a solution shows professionalism.

Closing lines

• "Let me know if you have any questions."
• "Looking forward to hearing from you."
• "Happy to discuss this on a call."
• "Thanks in advance for your help."
• "Have a great weekend."

Sign-offs

Before and after: real-style examples

Example 1: Asking for information

Before: "Dear Sir, I am writing to you with the purpose of requesting information regarding the prices of your products. I await your response. Kindly revert at the earliest."

After: "Hi Mr. Lee, I'm interested in your office furniture for our new team of 15 people. Could you send me your current price list and delivery times to Bogotá? Thanks in advance, Laura"

Example 2: Updating a client about a delay

Before: "The project is delayed. We will finish next week."

After: "Hi Sarah, I wanted to give you a quick update on the website project. Unfortunately, we need one more week to finish testing, so the new launch date is May 20. This will ensure everything works perfectly on mobile. I'm sorry for the change, and I'm happy to discuss it on a call if helpful. Best regards, Daniel"

Example 3: Following up

Before: "Why didn't you answer my email?"

After: "Hi Tom, just following up on my email from Monday about the contract. Have you had a chance to review it? We'd like to sign by Friday if possible. Thanks, Ana"

Tone: formal, neutral and informal

Most business emails today are neutral. Use formal language for official communication, complaints, legal matters and first contacts with senior people.

Common mistakes in business emails

• "I have a doubt" → "I have a question."
• "Please revert" → "Please reply" / "Please let me know."
• "Inform me" → "Let me know."
• "We are agree" → "We agree."
• "According to your request" → "As you requested."
• "I send you the file" → "I'm sending you the file" / "I've attached the file."
• No capital letters for days, months and languages → "Monday," "June," "English."

Email templates for common situations

Requesting a meeting

"Hi Mark, I'd like to set up a 30-minute call to discuss the new project timeline. Would Tuesday or Wednesday afternoon work for you? I'm in Bogotá time (UTC−5), but I'm flexible. Best regards, Laura"

Introducing yourself to a new client

"Dear Ms. Chen, my name is Daniel Ruiz, and I'll be your account manager from now on. I'm looking forward to working with you and your team. I'd love to schedule a short call next week to get to know your priorities. Kind regards, Daniel"

Thanking someone

"Hi Sofia, thank you so much for your help with the presentation yesterday. Your comments on the financial slides made a big difference, and the client was very impressed. I really appreciate it! Best, Ana"

Declining politely

"Hi James, thank you for thinking of me for the panel. Unfortunately, I won't be able to take part this time because of a project deadline. I hope it goes well, and please keep me in mind for future events. Best regards, Carlos"

Making a complaint

"Dear Customer Service, I'm writing about order 4582, which arrived on May 3 with two damaged items. I've attached photos. Could you please arrange a replacement or a refund? I'd appreciate a reply by the end of the week. Thank you, Marta Gómez"

Out-of-office message

"Thank you for your email. I'm out of the office until Monday, June 10, with limited access to email. For urgent matters, please contact my colleague Pedro at the address below. I'll reply as soon as I'm back. Best regards, Laura"

Writing for international readers

Many of your readers will also be non-native speakers. Help them understand you quickly:

• Use simple, common words instead of rare ones.
• Avoid idioms that may not translate, such as "touch base" or "ballpark figure," or explain them.
• Write dates clearly, such as "May 3, 2026," because 03/05 means different dates in different countries.
• Include time zones for every time.
• Use bullet points for lists of items or steps.
• Keep one main topic per email when possible.

Replying well

A good reply answers every question in the original email. When an email contains several questions, answer them in the same order, or copy each question and write your answer below it. If you need more time, acknowledge the email quickly: "Thanks for your message. I'm checking with the team and will get back to you by Thursday." A short acknowledgment shows professionalism and reduces follow-ups.

Email etiquette: "reply all," CC and BCC

Use "reply all" only when everyone needs your answer. Use CC (carbon copy) for people who should be informed but do not need to act, and BCC (blind carbon copy) when recipients should not see each other's addresses, for example in emails to many clients. When you add someone to a conversation, explain why: "I'm copying Pedro, who manages the logistics." When you remove people, say so: "Moving Laura to BCC to save her inbox."

A checklist before you click "Send"

• Is the subject line specific?
• Is the main point clear in the first two lines?
• Are requests and deadlines explicit, with time zones if needed?
• Is the tone appropriate for the reader?
• Are attachments actually attached?
• Did you check names, numbers and dates?
• Did you read it aloud once?

Email in remote and international teams

In remote teams, email often replaces conversations that would happen in an office, so clarity is even more important. Write complete messages that the reader can act on without asking you questions, and confirm meeting decisions in writing. Read English for remote work and how to run a meeting in English.

How we work on emails in class

In my Business English classes, students bring real emails they need to write or have received. We analyze the purpose, improve structure and tone, and build a personal bank of phrases for their typical situations: clients, suppliers, managers, colleagues. After a few sessions, most students write faster and with much more confidence. My background in corporate finance helps me understand the business context, from invoices to reports and negotiations.

Building your email habit

Like any skill, email writing improves with practice and feedback. Save good emails you receive from native speakers and colleagues, and notice how they open, make requests and close. Copy useful phrases into a personal document organized by situation. When you write an important email, draft it, wait a few minutes, then reread it as if you were the recipient. Ask yourself: is the purpose clear, is the tone friendly, is the request easy to act on? Over time, these habits make writing faster and much less stressful. Many professionals tell me that once they had a solid phrase bank, they cut the time they spent on emails in half.
