Cover letter in email body or attachment: when to use each

When to paste the cover letter into the email body

Pasting the letter into the email body is the right move when the posting gives no instructions, when you are cold-emailing a hiring manager directly, or when the company is small and unlikely to have a formal applicant tracking system. Recruiters at busy companies open dozens of emails a day. Removing one step, opening an attachment, increases the chance they read your letter at all.

This format also works well when you are following up on a referral. The email feels more like a personal note and less like a form submission, which matches the tone of a warm introduction.

• No attachment instructions in the posting
• Cold outreach to a hiring manager or recruiter
• Small company or startup with no ATS
• Following up on a referral or networking contact
• The posting says 'email us' with no further detail

When to send the cover letter as an attachment

Send an attachment when the posting explicitly asks for one. Phrases like 'attach your cover letter as a PDF' or 'send your CV and covering letter as separate documents' are clear instructions. Ignoring them signals you do not follow directions, which is a fast way to be filtered out.

Attachments are also appropriate when you are applying through a portal that has an email step at the end, or when the company is large enough that your email will be forwarded to HR and printed or filed. A well-formatted PDF survives that journey better than plain email text.

• Posting explicitly requests an attachment
• Posting specifies a file format such as PDF or Word
• You are applying to a large employer or government agency
• The email will likely be forwarded or printed internally
• You are sending both a resume and a cover letter as a package

When to include both

Some postings ask you to attach documents and also write a brief message in the email. In that case, write two or three sentences in the email body, something like: 'Please find my resume and cover letter attached for the Senior Analyst role. I have five years of experience in financial modelling and am excited to bring that to your team. I look forward to hearing from you.' Then attach the full letter as a PDF.

This approach covers both bases. The email body gives the recruiter a quick reason to open the attachments, and the attachment gives them a formatted document they can save or print.

How to format a cover letter in the email body

Strip out all formatting that depends on a word processor. No headers, no footers, no columns, no special fonts. Use plain text or very light HTML if your email client supports it. Keep the letter to three or four short paragraphs, around 200 to 300 words. Anything longer gets scrolled past.

Start with a clear subject line. A good template is: 'Application: [Job Title] - [Your Full Name]'. Some postings give you a reference number; include it. For example: 'Application: Marketing Manager (Ref: MM-2026-04) - Jordan Lee'.

Use single line breaks between paragraphs rather than indentation. Sign off with your full name, phone number, LinkedIn URL, and a link to your portfolio if relevant. Do not attach a signature image; many email clients block images by default.

1. Write a clear subject line with the job title and your name
2. Open with one sentence on why you are applying and what role
3. Write two short paragraphs on your most relevant experience and what you bring
4. Close with a call to action, such as requesting a brief call
5. Add your contact details below your name, no image signatures

How to format a cover letter as an attachment

Save as PDF unless the posting asks for Word. PDF preserves your formatting across every device and operating system. Name the file clearly: 'FirstName-LastName-CoverLetter.pdf'. Avoid names like 'CoverLetter-Final-v3.pdf', which look careless.

Use standard margins of 2.5 cm or 1 inch on all sides. Choose a readable font at 10 to 12 points, such as Calibri, Georgia, or Arial. Include a header with your name and contact details at the top, mirroring your resume header so the two documents look like a matched set.

Keep the letter to one page. Three to four paragraphs is the norm in the US, Canada, the UK, and Australia. UK and Australian employers sometimes expect a slightly more formal tone and a closing line such as 'I look forward to the opportunity to discuss my application further', but the structure is the same.

How Break-In Bad handles cover letters for you

When you apply through Break-In Bad, Omar writes a tailored cover letter for each job using facts you have already confirmed, so nothing is invented. For applications submitted directly on Greenhouse, Lever, Workday, and other employer sites, the cover letter is placed in the correct field automatically. You get a screenshot as proof of submission.

If you prefer to send an email application yourself, you can copy the generated letter into the email body or download it as a formatted document to attach. Either way, the content is specific to that posting rather than a generic template.
