Business English Email Phrases: 30 Sentences for Work

Picture one of your adult students, three months into a new office job in an English-speaking company. They know enough English to get through meetings, but every time they sit down to write an email to a manager or a client, they freeze. What do you write after “Dear Mr. Chen”? How do you ask for something without sounding too direct? What do you put before “Best regards”?

This situation is not rare. A survey by Grammarly found that 74% of business professionals say poor writing has caused them to miss deadlines or miscommunicate with colleagues. For ESL learners, that pressure is doubled — they are managing the content of the message and the grammar at the same time. The solution is not to teach grammar in isolation. It is to teach students a bank of functional phrases they can drop into emails with confidence.

This article gives you 30 business English email phrases organized by purpose, with context on when to use each one and some practical classroom ideas at the end.

Opening an Email

The opening line sets the entire tone of an email. ESL learners often start with “I am writing to you because…” which sounds overly formal and long-winded in modern business communication. These six phrases are what native speakers actually use.

The simplest and most common opening for a new message is “I’m writing to ask about…” It tells the reader the purpose immediately. A slightly softer version, “I wanted to follow up on…”, works when the student is continuing a conversation that already started, such as after a meeting or a previous email thread.

When the student needs to introduce themselves to someone new, “My name is [Name], and I’m [role] at [company].” is the standard first line before getting to the point. If the email comes from a referral, “[Name] suggested I reach out to you about…” immediately establishes social proof and explains why the stranger is writing.

For routine internal emails, two phrases keep things natural. “Hope you’re doing well” is a low-stakes opener that warms the message without taking much space. The more direct alternative, “Just a quick note to let you know that…”, works when the student wants to sound efficient and is writing to someone they already know.

Making Requests Professionally

This is where many ESL learners struggle the most. Direct languages like Chinese or Japanese have politeness built into verb forms, but English relies on modal verbs and softening phrases. Without those, a request can read as a demand.

The gold standard for a polite request is “Could you please [verb]…?” It is direct enough to be clear but polite enough not to sound pushy. A softer alternative, “Would it be possible to…?”, is useful when asking for something that might be inconvenient, such as moving a deadline.

When the student needs something by a specific date, “I was hoping to receive this by [date] — please let me know if that works.” sets the expectation while leaving room for the other person to push back. For situations where they have the authority to assign work, “Please could you send me [document/information] at your earliest convenience?” is appropriately formal without being stiff.

Two phrases help when the student is asking for approval. “I’d appreciate it if you could review and approve this.” is polite and clear. For more senior recipients, “Would you have a moment to look over [item] before [date]?” signals respect for the person’s time.

Responding to Messages

Knowing how to respond to an email — especially a request or complaint — is a skill that takes time to develop. These phrases give students a reliable framework for almost any response situation.

The most natural acknowledgement phrase is “Thanks for getting back to me.” It is casual enough for everyday work emails and signals that the conversation is moving forward. When acknowledging a request or instruction from above, “Noted, I’ll take care of that by [date].” shows the student has read, understood, and committed — all in one line.

When agreeing to a proposal or suggestion, “That sounds good — I’ll move forward on my end.” is concise and confident. Its counterpart for when something is not possible is “Unfortunately, that date doesn’t work for me. Would [alternative] suit you instead?” This structure — apologize briefly, then offer a solution — is a professional habit worth drilling.

For thanking someone for helpful information, “Thank you for clarifying that — it’s very helpful.” is warmer than a plain “thank you” and signals genuine engagement. Finally, when a student receives feedback on their work, “Thanks for the feedback. I’ll revise [item] and send it back to you by [date].” turns a potentially awkward moment into a professional exchange.

Following Up Politely

Following up on an unanswered email is something many learners find uncomfortable. In some cultures it feels aggressive; in English business contexts it is simply professional. The key is phrasing that assumes good faith rather than blame.

The most common follow-up opener is “Just wanted to follow up on my email from [day/date].” It is neutral and assumes the person was busy, not ignoring them. A slightly lighter version, “I wanted to check in — did you get a chance to look at this?”, is friendlier and works well in internal messages between colleagues.

When a decision has been pending for a while, “I’d love to move forward with this — is there anything I can clarify on my end?” shows initiative and offers to solve any blockage. For a formal follow-up after an interview or a proposal, “I’m still very interested in [opportunity/project] and wanted to confirm next steps.” keeps things professional while restating commitment.

When the student genuinely needs a decision by a specific time, “I need to confirm by [date] — please let me know your thoughts when you get a moment.” sets a deadline politely and gives the recipient a clear reason to respond quickly.

Closing an Email

The closing line shapes the last impression of every email. Students often default to “Please contact me if you have any questions” for every single email, which works but gets repetitive. A range of closings makes their writing feel more natural.

The most widely used call to action at the close is “Please don’t hesitate to reach out if you have any questions.” It is warm and open. A shorter alternative is simply “Looking forward to hearing from you.” — two words that do a lot of work without effort.

When handing something off, “Please find [document/details] attached.” should come just before the final sign-off. If the student is expecting action from the other person, “I’ll look forward to your confirmation.” signals that they expect a reply without being demanding. For when a meeting or call is the next step, “Please let me know a time that works for you.” hands control to the reader in a courteous way.

Common Email Mistakes ESL Learners Make

Understanding the phrases is half the job. The other half is knowing what students tend to get wrong, so you can address those patterns before they become habits.

The most common mistake is being too direct without softeners. A student might write “Send me the report by Friday” instead of “Could you please send me the report by Friday?” In English, dropping the modal and the “please” changes the register significantly — it reads as a command, which can damage working relationships.

The opposite problem is over-apologizing. “I am so sorry to bother you but I was just wondering if maybe you could possibly…” is exhausting to read and makes the student seem unsure of themselves. Teach them that one softener is polite; three in a row is excessive.

Using informal vocabulary in formal contexts is another recurring issue, especially for students who learned English through social media. Words like “hey,” “gonna,” “wanna,” and “FYI” may be fine in chat messages with colleagues but are not appropriate for emails to clients or senior management. Setting clear register expectations early saves embarrassment later.

Finally, many learners leave the subject line vague. A subject line like “Question” or “Hi” tells the reader nothing. Teach students to write subject lines that include the topic and action needed, such as “Meeting request — Project X timeline” or “Invoice 4421 — payment query.”

How to Teach These Phrases in Class

A handout of 30 phrases is useful, but it is not a lesson. Here are four approaches that actually move the language from passive recognition to active use.

Sorting activities work well for the first encounter with the phrases. Give students a mix of formal and semi-formal phrases and ask them to sort them by register or by function (opening / requesting / closing). This forces them to engage with meaning rather than just copy sentences into a notebook.

Pair the phrases with real email models. Find or write four or five short business emails — a request, a follow-up, a reply, a complaint response — and ask students to underline every phrase that matches one of the 30. Seeing the phrases in context helps students understand how they are combined in a real message, not just used in isolation.

Role-play scenarios are the fastest route to production. Give each pair of students a situation card: “You ordered office supplies two weeks ago and they have not arrived. Write an email to the supplier following up.” The constraint of a real situation forces students to choose appropriate phrases rather than use a generic template. You can find more ideas for this kind of task in this article on ESL activities that actually work in real classroom settings.

Once students are comfortable with written practice, move to peer review. Ask each student to write a short email, then swap and give written feedback using a simple checklist: Is the opening appropriate? Is the request polite? Does it close clearly? Peer review builds the analytical habit of re-reading for register, not just for grammar.

For students who want to go further — especially those preparing for professional roles — connecting these phrases to broader business English skills gives them a bigger picture of what workplace communication involves beyond email alone. And if you want to supplement with digital tools, using AI for daily English practice can help students rehearse these phrases outside of class hours with immediate feedback.
