Emailing a Professor in English: What International Students Get Wrong

You have a real question. Maybe the reading list link is broken, or you were ill on the day of the quiz, or you want to ask for a reference letter for a master's application. You open a new email, type "Dear", and stop. Is it Professor or Doctor? Is her surname the first name on the course page or the second? Is "Respected Sir" too formal, or "Hi" too casual? And is it "sincerly" or "sincerely"?

Writing to a professor in a new country is one of the first small challenges for an international student, and it matters more than it seems. A short email is often the first thing a member of staff ever reads from you, and sometimes the only thing before they decide how to answer. Errors stand out in a short message. So does a greeting that sounds wrong in the local culture, even when it is perfectly polite where you come from.

This guide covers the parts of an email to university staff that most often go wrong for students from other countries: names and titles, greetings and closings, the subject line, the words that get misspelled, and the phrases that read differently abroad. It applies whether you are at a university in the United States, Canada, the UK, Ireland, Australia or New Zealand, or at an English-medium university in your own country.

Why a short email deserves care

Readers judge writers by small errors, even when they try not to. In a 2016 study in PLOS ONE, Julie Boland and Robin Queen asked people to read short email replies to a housemate advertisement. Messages with typos and grammar errors led readers to rate the writers less favorably, and how strongly they reacted depended partly on the reader's personality. An earlier study by David Kreiner and colleagues, published in 2002, found that a short essay with many spelling errors led students to rate its writer as less able, especially as a writer, while four errors in a first experiment made no significant difference.

None of that means a professor will refuse to help you because you wrote "recieve". Most university staff read emails from students all over the world and are used to many kinds of English. But your request is competing with dozens of others in the same inbox. A clear, correct, respectful message is easier to answer quickly, and it makes the impression you want.

Names and titles: the part that matters most

The single most noticeable error in an email to a professor is a misspelled name. It is also the easiest to prevent. Copy the name from the course page, the syllabus or the university staff directory. Do not type it from memory, and do not trust your phone keyboard, which may "correct" an unfamiliar surname into a common word.

Check which part of the name is the surname. In English-speaking countries, the family name usually comes last: in "Sarah Okafor", Okafor is the surname, so you write "Dear Dr. Okafor" or "Dear Professor Okafor". Your own culture may order names differently. In Chinese, Korean and Hungarian, for example, the family name traditionally comes first, and some staff from those backgrounds give their names in English order while others do not. If the staff page says "Professor Li Wei" and you are not sure, use the full name: "Dear Professor Li Wei" is never rude.

Keep accents, hyphens and capital letters exactly as they appear. "Dear Professor Ferreira-Santos" and "Dear Dr. O'Brien" both lose something if you drop the hyphen or the apostrophe. Our guide to capital letters in English covers names with two capitals, such as McDonald.

Titles follow local custom. In the United States, "Professor" is safe for nearly anyone who teaches you. In the UK, Ireland, Australia and New Zealand, most teaching staff are lecturers, and "Professor" is a senior rank. For them, "Dr." is the right title if they hold a doctorate, which the staff page will show. If you cannot tell, "Dear Dr. Okafor" is rarely wrong for an academic with a doctorate. Never use a title with a first name: "Dear Professor Sarah" sounds odd to an English speaker, even though the same pattern is respectful in many other languages.

A small spelling point: American English writes "Dr." and "Mr." with a period, while British English usually writes "Dr" and "Mr" without one. Both are correct. Avoid "Mrs" or "Miss" for academic staff; if you need a title for a woman who is not a doctor or professor, "Ms" ("Ms." in American style) is the neutral choice.

Greetings and closings that sound right abroad

"Dear" followed by a title and surname is the standard opening, and it works in every English-speaking country. "Hello Professor Okafor" is also fine in North America, and many students use it. "Hi" alone, or "Hey", is too casual for a first message. Once the professor replies and signs with a first name, you may follow their lead, but there is no need to rush.

Some greetings are taught as polite in one place and sound unusual in another. Many students learn to open with "Respected Sir" or "Respected Madam", but in the UK, the US or Australia these sound old-fashioned and may surprise the reader. "Dear Sir" or "Dear Madam" without a name suggests you do not know who you are writing to, and it risks the wrong gender. "Dear Teacher" is how many students address teachers at school, but university staff are rarely called that. The name is always the better choice.

For the closing, "Best regards", "Kind regards", "With thanks" and "Sincerely" all work. Watch the spelling of the last two: regards has no u, and sincerely keeps the e from "sincere" before -ly. "Sincerly" is one of the most common errors in student emails. Then add your full name as it appears on the class list, and your student number if your university uses one. A professor with three hundred students cannot reply to "Ahmed" alone.

The subject line does half the work

Staff read the subject line before they decide when to open a message, and many students leave it empty or write "Hello" or "Question". A useful subject line says what the email is about and which course it concerns.

Compare "Question" with "ECON 101: missing link to Week 3 reading". The second can be answered in a minute, and it can be found again later. Other good examples: "Request for extension, Essay 2, Global Health seminar" or "Reference letter request for MSc applications". Check the course code and the spelling of every word in the subject line, because it is the first text the reader sees and the one most often typed in a hurry.

The words students misspell most in these emails

Some words appear in nearly every email to a professor, and a small group of them go wrong again and again. Here are the ones to watch, with the part that causes trouble.

Notice how many of these are about doubled letters. "Recommendation" is "re" plus "commend", which explains the single c and the double m. "Appreciate" doubles the p after the prefix, as "appear" and "approve" do. The word "grateful" goes back to the Latin "gratus", meaning pleasing or thankful, the same root as "gratitude", so there is no "great" in it. Learning the reason is what keeps a word fixed in memory.

Watch the confused pairs too, because a spell-checker will not catch them. "Advice" is the noun and "advise" the verb: "I would appreciate your advice", "Could you advise me". "Principal" and "principle", "affect" and "effect", and "than" and "then" are common in student writing. Our guide to affect, effect and other confused pairs covers the rest.

Finally, look out for your phone. Autocorrect can turn "definitely" into "defiantly" or an unusual surname into a common word. The result is a real word, so nothing will be underlined.

Phrases that read differently in another country

Some phrases are correct and polite in the English of one country but sound strange, or even demanding, in another. Knowing them is not about giving up your own English. It is about being understood the way you intend.

"Kindly do the needful" is common in Indian English, where it politely asks the reader to do whatever is necessary, but many readers in the UK or North America will not know what it means. Say exactly what you need instead. "Please revert" in Indian English means "please reply" or "report back"; elsewhere "revert" means to go back to a previous state. "Waiting for your reply" or "I need this urgently" can sound like pressure. "I would be grateful for your reply when you have time" asks for the same thing gently.

Direct requests can also sound blunt in English when they are perfectly normal in many other languages. "I want to meet you on Tuesday" becomes "Would it be possible to meet on Tuesday?" or "Could I come to your office hours on Tuesday?". The meaning is the same. The softer form is simply how English marks a request as polite.

At the same time, do not over-apologize. One "I am sorry to trouble you" is enough. Three apologies and a paragraph about how busy the professor must be make the email longer and the request harder to find. A short, specific, polite message is the most respectful thing you can send.

A model email, and a final check

Here is an email that would work in most English-speaking universities.

"Subject: ECON 101: request to meet about Essay 1 feedback. Dear Dr. Okafor, I am a first-year student in your Tuesday seminar for Introduction to Economics. I would appreciate the chance to discuss the feedback on my first essay, especially the comments on my use of sources. Would it be possible to meet during your office hours next week? Thank you for your time. Kind regards, Wei Zhang, student number 2026-1043."

It is under one hundred words, it names the course, and it asks one clear question. Before you send any email like it, do three things. Check the name against the staff page. Read the email aloud, slowly, which catches missing words and autocorrect errors. And search for any word on your own list of usual misspellings. For other writing that leaves a first impression, our guide to spelling in English job applications uses the same approach.

What to do next

Write down the six or seven words you use in almost every email to staff: the titles, your closing, "appreciate", "schedule", "available", "recommendation". Practice them from memory over the next week, a few minutes a day, then check each one. Research on retrieval practice, from Roediger and Karpicke's 2006 study onward, shows that recalling a word strengthens memory more than reading it again. A 2006 review by Nicholas Cepeda and colleagues found that practice spread across several days lasts longer than one long session.

Spelling.School is one way to do that: you hear each word, type it, see which letters went wrong and why, and the app schedules it for review with spaced repetition. Whatever you use, save your professors' names in your contacts exactly as written on the staff page. That one habit removes the error that matters most.

Questions people ask

How do I address a professor in an email?

Use "Dear" followed by the person's title and surname, such as "Dear Professor Okafor" or "Dear Dr. Okafor". Copy the name from the course page or staff directory so the spelling is exact. Do not combine a title with a first name, and only switch to a first name if the professor signs that way or invites you to.

Should I write Dr. or Professor in an email?

In the United States, "Professor" is safe for almost anyone who teaches at a university. In the UK, Ireland, Australia and New Zealand, "Professor" is a senior rank, so most teaching staff with a doctorate are addressed as "Dr." The university staff page usually shows the correct title.

Is it rude to start an email with Hi?

"Hi" on its own is too casual for a first email to a professor in most English-speaking universities. "Dear Professor Okafor" or "Hello Dr. Okafor" is safer. Once the professor replies in a more relaxed style, you can follow their lead.

How do you spell sincerely?

Sincerely is spelled s-i-n-c-e-r-e-l-y. It is the adjective "sincere" with -ly added, and the e from "sincere" stays. "Sincerly" is one of the most common misspellings in formal emails.

Is Respected Sir correct in English?

Many students are taught "Respected Sir" as a polite opening, but in the UK, the US, Australia and Canada it sounds old-fashioned. Readers there expect the person's name and title, such as "Dear Dr. Sharma". Using the name also avoids guessing the reader's gender.

What should I write in the subject line of an email to a professor?

Include the course code or name and the specific topic, for example "ECON 101: missing link to Week 3 reading". A clear subject line helps the professor decide when to answer and find the email again later. Check every word in it, because it is the first thing the reader sees.

How long should an email to a professor be?

Most emails to a professor should be short, often under 150 words. Say who you are and which course you are in, ask one clear question or make one clear request, and thank them. Longer explanations can go in a meeting or a follow-up message if the professor asks.
