Should the Cover Letter Go in the Email Body?
If you’re applying by email, put the letter in the body. Attaching it and writing “Please find attached my CV and cover letter” in the body means the reader has to open a file to discover whether the message was worth opening a file for.
The one exception is when the posting explicitly asks for a cover letter as a separate document — some processes route documents to a panel and the email body never travels with them. Then do both, and make the body a short version rather than a courier note.
Why the body wins by default
Email is read in a preview pane, often on a phone, in a queue. The body is free to read. An attachment costs a decision, a download, and a switch to another application.
The consequence is that a body letter is read by more people than an attached one, and an attached letter that isn’t previewed is functionally unsent. That’s not a claim about anybody’s diligence — it’s just where the friction is.
It also produces a better letter. Email prose is naturally shorter and less starched than document prose. People who write a stiff, formal page in a word processor will write something recognisably human in an email window, and the human version is the one that works.
What changes when it’s in the body
The body letter is the same argument, compressed. Practically:
Cut the date and address block. They’re a paper-letter convention. Email has a header.
Three paragraphs, not four. Merge the evidence paragraph and the judgement paragraph. Around 150–200 words total.
No “Dear Sir or Madam.” A greeting with a name if you have one, “Hi” or “Hello” if you don’t. Which register — see who to address it to.
One line naming the attachment, at the end, not the start. Resume attached. Two words. It’s not the message.
Nothing below the sign-off but your name and a phone number. Long signatures with logos and quotations turn a personal message into a broadcast.
A hypothetical body letter
For a small consultancy that advertised a research role by email, asking for CV and a note.
Hi Marta,
I’m writing about the Research Associate role. Your posting mentions needing someone who can turn client interviews into something the delivery team will actually use — that’s the specific gap I spent two years working on at Ellery.
The interviews themselves were never the hard part. What made the difference was killing the 30-page report: we moved to a two-page findings note plus a tagged transcript library, and the delivery leads started citing interviews in planning instead of asking us to summarise them again. Uptake went from occasional to routine within a quarter. The lesson I took from it is that research gets used when it’s cheap to reference, not when it’s thorough.
One thing I’d want to know is whether your findings currently reach delivery through a document or through a person, since that changes what’s worth building. Free most of this week. CV attached.
Best, Tomas Iles
Around 175 words. It contains everything a page-long letter would: the specific match, real evidence, a judgement, a question. It just doesn’t contain the scaffolding.
Subject lines
The subject line is not part of the letter but it decides whether the letter gets opened, and most people waste it.
Weak: Job Application — indistinguishable from forty others. Application — same. Resume – T. Iles — the reader has to open it to find out which role.
Better: Research Associate application – Tomas Iles. If the posting gave a reference number, include it; some processes route on it, and using it signals you read the instructions.
For cold outreach with no posting, the subject line does a different job entirely and needs to earn the open rather than file the message. That’s covered in cold outreach to a hiring manager.
File names, briefly
Name the attachment as though it were going to sit in a folder with two hundred others, because it is.
Tomas-Iles-CV.pdf, not CV_final_v3.pdf, not Document (2).pdf, and not CV.pdf — a folder full of files called CV.pdf is a real thing that happens and yours will be renamed or lost.
PDF unless asked for something else. If a posting or a recruiter asks for a Word document, send a Word document; there’s usually a reason involving whatever they paste it into, and quietly substituting a PDF is a small act of not listening.
The portal case
Portals vary and you don’t control them. Two patterns worth knowing:
A file upload field. Then it’s a document: keep the four-paragraph shape, one page, PDF. The date-and-address block is still optional and honestly still looks fussy, but nobody has ever been penalised for it.
A free-text box. Write the body-letter version, and check what the box does to your formatting before you submit. Many strip line breaks, which turns three paragraphs into one wall. If you can’t tell, write shorter paragraphs and avoid anything that depends on layout — no bullet lists, no bold, no em-dash-heavy sentences that need visual separation to parse.
If the box has a character limit, treat it as the real brief and cut accordingly — what to cut when the letter runs long applies with a hard deadline.
Both, when you have to
If a process wants a separate document and you’re sending it by email, don’t waste the body.
Write a four-sentence version in the body — the opening, the single strongest specific, and the offer to talk — and attach the full letter. The body earns the open; the attachment satisfies the process. What you’re avoiding is the covering note that says nothing, because that’s the version where your one chance at a preview pane is spent on the phrase “please find attached.”
