A professor in Europe or North America may get dozens of emails a week from people she has never met. Most start with "Dear Sir/Madam, I am interested in a fully funded PhD" and get deleted in seconds. The few that get a reply are short, specific and show the sender has read her work.
This guide shows you how to write that second kind of email. It works whether you are a Nigerian with a master's degree, a Kenyan lecturer moving into research, or a Ghanaian or South African graduate applying abroad. For the bigger picture on funding, read our guide to finding and reading a funded PhD offer first.
When you should email, and when you shouldn't
Whether to email depends on how the position is set up. Check this before you write anything.
- Advertised, funded project with a named supervisor: email only if the advert invites questions or you have a real one. Otherwise follow the application instructions exactly. Many departments score applications through a portal, and a personal email changes nothing.
- Department-wide funding competition (you choose the topic): emailing potential supervisors is usually expected, because you need someone willing to back your application.
- No advert at all: you are asking a supervisor to consider you and to help you find funding. This is the hardest route. Ask about it only after you have found funding schemes you could apply to together.
Rules differ by country and even by department. Some programmes, especially in parts of Europe, treat the PhD as a job you apply for through a vacancy. Others in North America admit you to a department and match you to a supervisor later. Read the department's "how to apply" page and do what it says.
Do the groundwork before you write a word
A good email takes about an hour of reading and ten minutes of writing. Spend your time in that order.
- Read two or three recent papers by the supervisor. Read the abstracts and conclusions at least, and the methods if your field is technical. Note one thing you can say about each that is more than "interesting".
- Check the lab or group page. Look for "current students", "open positions" and "prospective students". Some professors state plainly whether they are taking students and how they want to be contacted.
- Confirm the funding route. Find out what scholarships or studentships the university or country offers to international students, and whether your nationality qualifies. Our post on reading scholarship eligibility rules will help you do this properly.
- Check the entry requirements. Minimum degree class or grade, language test, and whether a master's is required. If you don't meet one, you need to know now.
- Prepare your attachments: a one-page CV (see our one-page scholarship CV guide), and, if asked, transcripts and a short research outline.
The structure of an email that gets read
Aim for 150 to 220 words. Every sentence should do a job.
Subject line
Be plain and specific. "Prospective PhD student: [your topic] and your work on [their topic]" is better than "PhD Application" or "Request". If you are responding to an advert, put its title or reference number in the subject.
Paragraph 1: who you are, in two sentences
Give your current degree, your university and your research area. Do not start with your life story or with praise.
Paragraph 2: why this supervisor
Name one paper or project and connect it to something you have done. This is the paragraph that proves you are not mass-mailing.
Paragraph 3: your idea or fit
Say in two or three sentences what you want to study, or how your master's work fits their group. You are not submitting a full proposal. You are showing that you can think like a researcher.
Paragraph 4: the ask
Make one small, easy request. "Would you be open to a short call, or could you tell me whether you expect to supervise new students next year?" is easy to answer. "Please guide me on how to get a scholarship" is not.
Sign-off
Full name, current institution, a professional email address (not a nickname account), and a link to your Google Scholar, ResearchGate or university profile if you have one.
A worked example (hypothetical)
Imagine Amaka, a Nigerian with an MSc in environmental engineering, who wants to study wastewater reuse. She finds a professor whose recent paper tests low-cost filtration in informal settlements. Her email might read:
Subject: Prospective PhD student: low-cost filtration for urban wastewater reuse
Dear Professor Reyes,
I am an MSc graduate in environmental engineering from a Nigerian federal university, with a thesis on sand and biochar filtration of greywater.
I read your 2025 paper on filtration in informal settlements, and your finding that maintenance, not materials, caused most failures matches what I saw when monitoring six household units in Lagos. I would like to study how maintenance routines can be built into filter design.
I am planning to apply to the university's international PhD funding round. Do you expect to supervise a new student starting next year, and would you be willing to look at a two-page outline of my idea? My CV is attached.
Kind regards,
Amaka Obi
Notice what it does: one paper cited with a real point, one piece of her own evidence, one clear question, and it shows she knows a funding round exists. It is invented for illustration, so don't copy the details.
Mistakes that get emails ignored
- Copy-paste emails. If the professor's name or field is wrong, or the email could be sent to anyone, it will be treated as spam.
- Asking for funding before showing fit. "Please sponsor me" in the first line signals you haven't researched. Show your fit first and ask about funding routes second.
- Attaching everything. Five PDFs in a first email look heavy. Send a CV and offer more on request, unless the advert asks for specific documents.
- Flattery instead of detail. "I admire your outstanding work" says nothing. A sentence about a specific finding says a lot.
- Emailing a whole department. Supervisors often talk to each other. Contact a few people in different groups, one by one, and keep each email truly individual.
- Paying anyone to do this for you. Agents who promise "supervisor acceptance letters" for a fee are a warning sign. See our post on spotting fake scholarship agents.
Follow-up, silence and replies
Wait two to three weeks before a follow-up, longer during exam periods or summer holidays. Send one short reply to your original message, restating your question in a line. If there is still no answer after that, move on. Silence usually means "no capacity", not "you are not good enough".
If the reply is positive, treat it as the start of a conversation. Send the outline they asked for within a few days, and ask what the next formal step is. Keep in mind that an encouraging email is not an offer. The official admission and the funding decision come from the university or scholarship body, in writing.
If the reply is "I have no funding", ask politely whether they know of schemes your nationality can apply to. Some will point you to the right one.
Adjusting for your situation
| Your situation | What to change |
|---|---|
| Fresh master's graduate | Lean on your thesis. One strong paragraph about your project and method matters more than a list of courses. |
| Working lecturer or professional | Say what practical problem you have seen at work, and how it links to their research. Mention whether you can get study leave. |
| Few or no publications | Don't apologise. Offer your thesis, a conference presentation, or a short writing sample instead. |
| Weaker grades | Don't hide them. Put your strongest evidence of research ability first and state your grades plainly. |
| Poor internet or power | Draft offline, send early in the day, and keep attachments small (under a few MB) so the email goes through. Check your inbox for replies at least every other day. |
Frequently asked questions
Should I attach a full research proposal?
Not in the first email unless the advert asks for it. Describe your idea in two or three sentences and offer to send an outline. Our personal statement plan can help you organise your thinking.
Can I email a supervisor if my grades are borderline?
Yes, but check the written entry requirements first. A supervisor can't usually override a minimum set by the university or funder, so ask whether your profile could be considered.
What if I am applying for a project that already has a named supervisor?
Then your email should be even shorter. Ask one specific question about the project, or just apply through the official route.
Do I need a referee before I email?
Not yet, but line up two people early. If you're short of lecturers, see our post on choosing referees for a scholarship.
Your next step
Today, pick three supervisors whose recent work really matches your interests. Read one paper from each, write down one specific point per paper, and draft the second paragraph of your email first. If that paragraph is hard to write, you have found a weak match, which is better to learn before you hit send.
Scholarship details, deadlines and eligibility can change. Always confirm on the official website before applying, and never pay anyone who promises to "guarantee" a scholarship.
