A professor in Europe once described her inbox during application season: dozens of emails opening with “Dear Sir/Madam, I am very interested in your esteemed research”, sent to hundreds of people at once, occasionally with someone else's name left in. She doesn't reply to those. The ones she answers mention one recent paper from her group, pose a specific question the writer wants to pursue, and run to fewer than 200 words.
An enquiry email is not an application. It is the opening line of a professional conversation, and its only job is to get a reply.
When to contact supervisors first, and when not to
| Model | Contact first? | Why |
|---|---|---|
| PhDs in the UK, Australia, much of Europe and Asia | Strongly advised, often effectively required | Applications need a supervisor willing to take you on |
| Advertised funded PhD positions | Yes, if you have a genuine question | Adverts usually name a contact |
| US departmental PhD admissions | Optional; helpful but rarely decisive | A committee admits; supervisors are matched later |
| Taught master's | Usually unnecessary | The admissions office handles applications |
Some department pages say explicitly: please do not contact faculty before applying. If you see that line, respect it.
Find the right person before you write
- Start with the paper that excited you most in the past two years; look at the corresponding or senior author.
- Visit their page: are they taking students, how big is the group, is any project recruiting?
- Read at least two of their recent papers in full, not just the abstracts.
- Check they are still at that institution; old profile pages linger after people move.
A realistic list is eight to fifteen people, each with an individually written email. A template sent to a hundred people is the fastest route to a hundred silences.
A 150-word structure
- Subject line: specific. “Prospective PhD applicant – soil microbiome and drought tolerance (2027 entry)”.
- Sentences 1–2: who you are, where, what you study. No adjectives.
- Sentences 3–4: one of their papers and something specific you took from it or wondered about.
- Sentences 5–6: the question you want to pursue and relevant experience, such as a project or technique.
- Sentence 7: a clear ask: are they taking students this cycle, and would they be open to a brief conversation?
- Attachments: a two-page PDF CV, plus a one-page research outline if you have one. No transcripts or certificates in the first email.
An example to adapt
Dear Professor [Surname],
I am a final-year MSc student in Environmental Science at [university], studying how irrigation frequency affects rice paddy soil bacteria. Your 2025 paper on microbial shifts under intermittent drought was directly relevant to me: I was surprised that the effect weakened after the third cycle, and wondered whether soil organic carbon might explain it.
I would like to pursue a PhD on this question in tropical soils. For my thesis I used 16S sequencing and analysed the data in R, which I believe aligns with your group's methods.
Are you planning to take on PhD students for 2027 entry? If so, I would be grateful for a short conversation. My CV is attached.
Kind regards,
[Name]
Notice the question about organic carbon. It shows the writer read closely enough to form a question of their own, and that is the detail that separates this email from dozens of others.
Timing and follow-up
- Write roughly six to ten months before the application deadline, leaving time to talk and perhaps co-develop a proposal.
- Avoid exam-marking periods and long holidays in that country.
- No reply after about two weeks: send one short follow-up in the same thread, three sentences at most.
- No reply after that: stop and move on. Silence is usually the answer.
Reading the replies
| Reply | What it usually means | What to do |
|---|---|---|
| “I'm not taking students this year.” | Clear, and not about you | Thank them and ask whether they can suggest a colleague |
| “Please apply through the online system.” | Neutral, no commitment | Apply and name them in your application |
| “Send me a one- or two-page proposal.” | Interested | Write carefully and send within a week or two |
| “Let's set up a video call.” | Genuinely interested | Prepare as you would for an interview |
| “You will need to secure your own funding.” | There is space but no money | Ask which scholarships their past students have held |
Preparing for the first call
- Summarise your research idea in two minutes, without reading from slides.
- Know the group's latest papers and methods.
- Bring three questions about the group: how many doctoral students, how often they meet, conference opportunities, and whether students typically finish on time.
- Ask if you may speak to a current PhD student; it is the best way to learn what the lab is really like.
Easy mistakes to avoid
- Wrong title or name, or a previous recipient's name left in.
- Five or six attachments in the first message.
- Questions already answered on the admissions page, such as deadlines or fees.
- Flattery in adjectives instead of engagement with the research.
- A two-page letter narrating your entire education.
This week, pick three recent papers that genuinely made you curious and write down one question for each that the paper left open. Those three questions are the core of your first three emails, and the best evidence you can offer that you are ready to do research.
Câu hỏi thường gặp
Should I email a professor before applying for a PhD?
In the UK, Australia and much of Europe and Asia, it is strongly advised because applications usually need a willing supervisor. In the US it can help but is rarely decisive, since a departmental committee makes admissions decisions.
How long should an email to a potential supervisor be?
About 150 to 200 words. A short, specific email that refers to the professor's work and states a clear research question is far more likely to receive a reply.
What if a professor doesn't reply to my email?
Wait about two weeks and send one brief follow-up in the same thread. If there is still no response, move on to other potential supervisors.
Should I attach a research proposal to my first email?
Attach your CV; a one-page outline is a bonus if you already have one. There is no need to send transcripts or certificates at this stage.
How many professors should I contact for a PhD?
Around eight to fifteen genuinely relevant people, each with a tailored email. Mass templates rarely get responses.
