Letter of Recommendation Request Email
Asking for a recommendation is a request for several hours of someone’s unpaid time, and the quality of what comes back correlates almost entirely with how the request was made.
A vague ask produces a vague letter. Not because the referee is lazy, but because a letter written from memory alone can only contain what memory retained, which after two years is a job title and a general impression.
The fix is to send a packet, not a request. It is twenty minutes of your work and it is the difference between a letter that describes you and one that could describe anyone.
How much notice, and who to ask
Three to four weeks is the minimum for a substantial letter; six is better where several are needed at once, as with graduate applications. A week is enough only for someone who has written for you before and can adapt an existing letter.
Ask people who supervised the work rather than people with impressive titles. A direct manager who watched you solve something writes a better letter than a senior executive who knows your name — admissions committees and hiring managers can both tell the difference immediately.
Ask more people than you need where the process allows it. Referees fall ill, forget and miss deadlines, and a spare is far easier to arrange in advance than a replacement a week before a deadline.
What to send with the request
The reminder is the item that changes the letter most and the one people leave out most, usually out of a worry that it looks presumptuous. It does not. Every experienced referee is grateful for it, and the ones who write many letters will tell you so.
- The deadline, in bold, and the submission method — portal link, email address, or a sealed letter by post.
- Your current resume or CV.
- What you are applying for, with the posting or programme description.
- A short reminder of what you worked on together, with two or three specific things you did.
- Any themes the recipient wants addressed — many graduate programmes publish these.
- Whether the letter is confidential, and whether you have waived access.
Example request email
Subject: Recommendation letter request — MPH applications, due December 1
Dear Professor Lindqvist,
I am applying to Master of Public Health programmes this cycle and I am writing to ask whether you would be willing to write me a letter of recommendation. The earliest deadline is December 1, so there would be about seven weeks.
You supervised my work on the county immunisation coverage study in 2025 — I built the geocoding pipeline and did the sensitivity analysis on the census-tract estimates, and presented the findings at the departmental seminar in April.
I have attached my CV, the programme descriptions for the four schools, and a one-page note on the specific projects and what my role was in each, in case it is useful. Three of the four use a portal and will email you a link once I submit; the fourth takes a PDF by email and I have included the address.
Please do say if you would rather not, or if the timing is difficult — I would much rather know now than have you feel obliged.
Thank you very much for considering it.
With best wishes, Nnamdi Sorensen.

Give them an easy way to decline
This line does more work than any other in the email. A referee who cannot write a strong letter, or who genuinely has no time, needs a way to say so that does not require them to disappoint you directly.
Without it, the common outcome is not a refusal but a lukewarm letter — technically positive, evidently thin, and worse for your application than no letter at all. Readers of these are practised at spotting one.
Phrase it plainly: "please do say if you would rather not". Then take a hesitation at face value. Someone who says they are not sure they are the right person is telling you something, and pressing past it produces exactly the letter you did not want.
Managing multiple letters and deadlines
Graduate and fellowship applications typically want two to four letters across several institutions with different deadlines and different portals, which is an administrative problem before it is anything else.
Keep one table: referee, institution, deadline, submission method, date requested, date submitted. Send it to nobody — it is for you — but it is what stops a missed portal invitation becoming a missed deadline.
Send one reminder about ten days out, and a second three days out if the portal still shows nothing received. Both should be short and apologetic in tone rather than in length. Almost every late letter is a forgotten letter, not a refused one, and referees are generally glad to be reminded.
Afterwards
Thank them when the letter goes in, not only when you hear the outcome. The work is done at submission and that is when acknowledgement lands.
Then tell them the result, whatever it is. Referees rarely find out, and being told is the main non-monetary return on several hours of work. It is also what makes the second request, two years later, an easy yes.
If the answer was no, tell them anyway. Nobody enjoys hearing it, but a referee who wrote for you and never learned what happened is markedly less likely to write again — and a rejection this cycle is not the last time you will need a letter.
Frequently asked questions
Three to four weeks minimum, six where several applications are involved. Under two weeks you are asking for a letter written from memory under time pressure, which is rarely the letter you want.
The deadline and submission method, your resume, the posting or programme description, and a short reminder of specific work you did together. That last item improves the letter more than anything else you can supply.
No, and it is expected. One reminder around ten days out and a second a few days before is normal practice. Almost every late letter is simply a forgotten one.
Whoever supervised work relevant to what you are applying for. Academic programmes usually want at least one academic referee; employers almost always prefer a direct manager over a more senior person who knows you less well.
