How to Send a Cover Letter by Email
You have written a cover letter you are genuinely proud of. Then you open your inbox to send it, and a fresh set of questions appears. Do you attach it or paste it in? What goes in the subject line? What do you even write in the email itself? Getting the cover letter email right matters more than most people realise, because a clumsy send can undo hours of careful writing before anyone has read a word.
The good news is that the mechanics are simple once you know the conventions. Get them right and your application looks professional, lands in the right hands, and actually gets opened.
Attach or paste in the body?
This is the question that trips most people up, and the honest answer is that it depends on the instructions. Always read the job advert first. If the employer asks for your cover letter as a separate attachment, do exactly that. If they are silent on the matter, you have a choice to make.
The safest modern approach is to do both in a light way. Write a short, warm version of your letter in the body of the email itself, then attach the full, formatted letter as a PDF alongside your CV. This way the reader gets an immediate sense of you without downloading anything, and the polished document is there if they want it.
A few rules keep this tidy:
- Send your cover letter and CV as PDFs, never as editable Word files that can shift on someone else’s screen
- Name your files clearly, such as “Jane Smith Cover Letter.pdf”, not “coverletter final v3.pdf”
- Never send a cover letter as the only attachment with a blank email body, as an empty message feels careless
Write a subject line that gets opened
Recruiters and hiring managers scan crowded inboxes at speed. A vague or missing subject line is an easy thing to skip, so treat this small field as prime space. Your goal is to be instantly clear about who you are and what the email is for.
A reliable format is your name, the role and the reference number if there is one. Something like “Jane Smith, Marketing Assistant application, ref MA204” tells the reader everything they need before they even open the message. If the advert specifies a subject line, use their exact wording, because it may feed an automated filing system.
Avoid anything that reads as a gimmick. Clever or over-familiar subject lines rarely land the way you hope, and they can make a serious application look flippant.
Keep the email body short and human
The body of your email is not the place to repeat your entire letter. Think of it as a brief, friendly introduction that points to the documents attached. Three or four sentences is plenty. Greet the reader by name if you can find it, say which role you are applying for, add one line on why you are a strong fit, and mention that your CV and cover letter are attached.
This short note still needs care, because it is the first thing the reader sees. It should carry the same warmth and clarity as the letter itself. If you are unsure what to emphasise in that opening, our guide on what to include in a cover letter will help you decide which points deserve to lead, so the email version distils the strongest ones.
Close the email politely, thank them for their time, and sign off with your full name and contact details. A tidy signature with your phone number and, if relevant, a LinkedIn link makes it effortless for them to respond.
Get the details right before you hit send
Small technical slips can quietly sabotage a strong application. Before you send anything, run through a quick checklist to make sure the mechanics are working for you rather than against you.
Check that you are sending from a sensible email address. A plain address built from your name always beats a jokey one from years ago. Confirm the recipient’s address is correct, and be careful with reply-all if the advert came through a chain. Double check that the attachments are actually attached, since forgetting them is one of the most common and most embarrassing mistakes. Finally, send yourself a test copy or preview on your phone to see exactly how it will look when it arrives.
Timing can help too. Emails sent early in the working day tend to sit near the top of the inbox when the reader first sits down, rather than getting buried under the afternoon rush.
Sending a letter no one asked for
Not every cover letter email is a response to an advert. Sometimes you are writing to an organisation you admire that has no live vacancy, and the mechanics shift slightly. Here the subject line and opening lines have to work even harder, because you are interrupting someone who was not expecting to hear from you.
In this situation the email needs to earn its read within the first line, making it clear why you are writing and what you offer before the reader loses interest. Our advice on how to write a speculative cover letter covers how to strike that balance between confidence and courtesy, so your unsolicited approach feels like an opportunity rather than an intrusion.
A clean send is the final polish
Emailing a cover letter is not the hard part of a job search, but it is the last thing that stands between your writing and the reader. A clear subject line, a short human note, well named PDF attachments and a careful final check together make the difference between an application that looks effortless and one that looks rushed.
If you would rather focus your energy on the words themselves and hand the presentation to a professional, let our writers polish your application so every part of it, right down to the file it arrives in, works in your favour.
