Writing Professional Emails in English When It Is Your Second Language

"I am writing to kindly inform you..." is usually too formal

"I am writing to kindly inform you that there will be a delay in the completion of the report" is grammatically correct, but "The report will be two days late" is usually better in a working email.

This difference is difficult because the first sentence feels safer. Many Vietnamese professionals have learned that English at work should be polite, careful, and indirect. That instinct is useful when speaking with a senior colleague or an external client. In email, however, too much ceremony can make a simple update sound distant, anxious, or less clear than intended.

The goal is not to write casual English. The goal is to calibrate your register: the level of formality, directness, and warmth that fits this person, this situation, and this relationship.

From sessions with adult Vietnamese learners, I often see the same gap. The writer knows the vocabulary and can produce a correct sentence. They still pause for several minutes over Dear or Hi, wonder whether "please kindly" is polite enough, and write a long introduction before stating the actual request.

Professional email becomes easier when you treat it as a workplace action rather than a grammar exercise. You are updating someone, asking for a decision, checking a detail, or repairing a delay. The language should help that action happen.

Start with the relationship, not a fixed rule

There is no single correct level of formality for every English email. "Dear Mr. Smith" is not always more professional than "Hi James," and "Hi" is not always too informal. The right choice depends on whether you are writing to a first-time contact, a regular colleague, a manager, a customer, or a group.

Consider these common openings:

• Dear Ms. Patel, Suitable for a formal first contact, an application, or a sensitive external message.
• Hello James, Professional and slightly neutral. Useful when you want warmth without sounding familiar.
• Hi James, Normal for many ongoing workplace relationships.
• Hi everyone, Appropriate for a familiar internal group.

If the other person consistently writes "Hi" and signs off with their first name, that is useful evidence about the working relationship. You do not have to copy every detail, but matching their general level of formality is often a good starting point.

Names also require care. If you are unsure whether to use a first name, look at how the person signs their emails or how colleagues address them in meetings. If you do not know the name, "Hello" followed by the team or role can be clearer than an awkward guess. "Hello Recruitment Team" is more natural than a literal translation of a formal Vietnamese salutation.

A useful boundary is this: do not make an email more formal simply because you are writing to someone from another country. International colleagues still have individual preferences. A British project manager may prefer a short, direct update, while a local senior leader may prefer more formal language. Nationality is not a substitute for observing the relationship.

Subject lines should help the reader act

A subject line does not need to sound impressive. It needs to make the purpose visible. Avoid subjects that only describe the general topic:

• Project
• Meeting
• Important information
• Regarding our previous discussion

These subjects force the reader to open the message before they know what is needed. A more useful subject includes the action, item, or timing:

• Approval needed: Q4 training budget
• Updated timeline for the product workshop
• Question about invoice 1842
• Follow-up: Tuesday client meeting
• Request to move Friday's interview

Use a subject line that remains accurate if the email is forwarded or revisited later. "Quick question" may feel friendly, but it gives no useful information. "Question about the onboarding schedule" is still concise and gives the reader context.

Be careful with urgency words. "Urgent" should mean that a delay creates a real problem, not simply that you would like a quick answer. If a response is needed by a particular time, say so directly: "Could you confirm by 3 p.m. Thursday?" This is clearer and less alarming than writing "URGENT!!!"

Say the main thing before the explanation

Writers who are worried about sounding rude often place the request at the end of a long introduction. In English workplace email, the reader usually benefits from the purpose in the first sentence or two.

Instead of this:

With regard to the matter that we discussed in our previous meeting, and after carefully considering the current situation and the various factors that may have an impact on the project, I would like to kindly ask if it might be possible for you to provide your feedback when you have time.

Try this:

Could you review the attached proposal and send your feedback by Thursday?

You can add context after the request:

Could you review the attached proposal and send your feedback by Thursday? We need to confirm the scope before Friday's client call.

This is not blunt. "Could you" is already a polite request. Other useful forms include:

• Could you please confirm the delivery date?
• Would you be able to share the revised figures?
• Could you let me know whether this time works for you?
• Please send the final version when it is ready.
• I would appreciate your feedback by Monday.

Notice the difference between "Please kindly send me..." and "Could you please send me...?" The first is understandable, but "please kindly" is often an unnecessary combination. One polite marker is usually enough.

Use direct language when reporting a problem

Overcautious writing becomes especially visible when something has gone wrong. A writer may use several softening phrases and never clearly state the impact. The reader then has to interpret the situation.

Imagine a Vietnamese professional named Mai writing to a British project manager about a delayed deliverable. Her first draft says:

Dear Oliver,

I am writing this email to kindly inform you that, due to some unexpected problems which happened during the process, perhaps there may be a possibility that we cannot complete the testing report as the timeline that we previously discussed. We are very sorry for any inconvenience caused and hope you can understand our situation.

The message is polite, but it leaves several questions unanswered. Is the delay certain? How long is it? What caused it? What does Oliver need to do?

A stronger version might be:

Hi Oliver,

The testing report will be ready on Thursday, two days later than planned. We found an issue in the data that needs to be checked before we send the final version. I'm sorry for the delay. We will send an interim update tomorrow, and I'll confirm the final delivery time by 3 p.m.

Best,
Mai

This version is not less respectful. It gives the facts, acknowledges the problem, and explains the next step. "I'm sorry for the delay" is enough. A long apology can make the message sound uncertain without helping the reader solve anything.

When reporting a problem, try to include four elements:

1. The current fact: What has happened?
2. The impact or change: What is different from the original plan?
3. The reason: Include a brief explanation if it is relevant.
4. The next step: What will happen, and when?

You do not need to provide a complete history of every difficulty. Workplace readers usually need enough information to decide what to do next.

Follow up without sounding apologetic

Follow-up emails create another register problem. Some learners write only "Any update?" which can sound impatient, especially without context. Others write a very long apology for contacting the person again.

A useful follow-up briefly identifies the earlier message and states the action you need:

• Hi Lan, I'm following up on the contract draft below. Could you confirm whether the legal team has reviewed it?
• Hello David, just checking whether you had a chance to review the proposed schedule. We need to book the room by Wednesday.
• Hi Priya, I wanted to follow up on my request for the sales figures. Could you send them by 2 p.m. today if possible?

"Just checking" can make a reminder sound lighter, but you do not need to use it every time. If the deadline matters, a direct sentence is more useful: "Could you send the figures by 2 p.m. today?"

If you are sending a second or third reminder, add information rather than repeating the same sentence. Explain the consequence or offer an alternative:

Hi Daniel,

I'm following up on the access request below. We need the account before tomorrow's training session. If you are not the right person to approve this, could you point me to the correct team?

Thanks,
Nina

This is firm without being aggressive. It also gives the recipient an easy way to help.

When more formality is the right choice

Directness is not always better. A short "Hi, send this today" may be acceptable between close teammates, but it is not a good model for every workplace situation. Formality still has a purpose when you are introducing yourself, communicating with a customer, addressing a serious complaint, or writing about a sensitive employment matter.

In those situations, use a respectful greeting, complete sentences, and a calm explanation. You can still avoid inflated phrases. Formal does not mean vague, and polite does not mean apologizing for making a reasonable request.

There is also a difference between sounding warm and sounding overly familiar. Exclamation marks, emojis, and phrases such as "Hope you are doing super well!" may suit one team and feel uncomfortable in another. Observe the existing communication style before adopting it, especially with a new contact.

At NativeX, we practise these decisions as scenarios rather than isolated grammar points. A learner may rehearse a delay update, then try the same message to a manager, a peer, and an external partner. The wording changes because the relationship and the consequence change. The useful question is not "What is the most polite English sentence?" It is "What does this reader need from me, and what level of formality will make that clear?"

If you want to practise email register directly, you can work through these workplace situations in NativeX sessions. Contact [email protected] or visit getnativex.com.

The most professional email is often the one that lets the reader understand the situation, respond appropriately, and move on with the work.
