How to email your resume: subject line, body, and attachment

Emailing a resume looks like a formality, which is why it gets neglected. But the email is the first work sample a hiring manager receives: a vague subject line, an empty body, or a file named "resume_final2.docx" signal carelessness before anyone opens the attachment. In an inbox that gets fifty applications a day, those details decide which one gets opened first and which one gets lost.

This guide covers the whole send: how to prepare the file, what to write in the subject line so the message can be found and sorted, how to draft a body of a few lines that makes the reader want to open the resume, and what to check before hitting send. It includes two sample emails, one responding to a job posting and one for a cold application.

The file: PDF, name, and size

The resume goes as a PDF unless the posting explicitly asks for another format. A PDF keeps the layout intact on any device, cannot be edited by accident, and is read without trouble by current applicant tracking systems. A Word file can open with substituted fonts or shifted page breaks, and it exposes tracked changes if they were not cleared. How to export it correctly, at Letter size, and what to check in the result is covered in the guide on the resume as a PDF.

The file name is part of the message. The person receiving the email saves it in a folder next to dozens of other files, and "Resume.pdf" or "Document1.pdf" becomes impossible to find. The convention that works:

• FirstName-LastName-Resume.pdf, or with the role if it helps: FirstName-LastName-Resume-Accounting-Analyst.pdf.
• No spaces, no special characters, no version markers ("v3," "final," "FINAL2").
• Under 2 MB. A text-based resume weighs less than 500 KB; anything above 2 MB is almost always an uncompressed image or background.

If a cover letter is attached too, it goes in a second file with the same convention (FirstName-LastName-Cover-Letter.pdf), not pasted into the resume.

The subject line

The subject line has two jobs: to identify the email as an application in a full inbox, and to make it findable with a search weeks later. For that it needs three pieces of information: what it is, which role, and from whom.

If the posting specifies a subject line format or a requisition number, follow it to the letter: many companies sort the inbox with automatic rules, and a different subject can land the message in a folder nobody checks. When there is no instruction, "Application: [role] - [first and last name]" covers every case.

The body: what to say in five lines

The body of the email is not the cover letter and not a summary of the resume. It is a short message, four to six lines, that says which role is being applied for, why the profile fits in one sentence, and what is attached. The reader decides in seconds whether to open the file; the body has to make that decision easy, not replace the reading.

The structure that works:

1. Greeting by name when known ("Dear Ms. Burton," "Hi Martin,"). If not, "Dear Hiring Manager" or "Hello."
2. Purpose in one sentence: which role and where the posting was seen.
3. Fit in one or two sentences: the single most relevant fact about the profile for that role, with a number if there is one.
4. Attachments: what is being sent.
5. Close and availability: brief thanks, openness to an interview, signature with phone number.

What to leave out: the whole career story, a repeat of the resume, apologies for taking up time, salary if nobody asked, and filler phrases like "I am writing to express my interest in." A twelve-paragraph email tells the reader the person cannot summarize, which is a skill almost every job requires.

Example: email responding to a job posting

Subject: Application: Purchasing Analyst (Req. PA-0326) - Megan Alvarez

Dear Ms. Burton,

I'm applying for the Purchasing Analyst position posted on Indeed on September 8.

I've spent four years in purchasing for a food distributor, where I manage a portfolio of 60 suppliers and last year negotiated a 9% reduction in the cost of our core inputs. I work daily in SAP MM and advanced Excel, the two requirements listed in the posting.

My resume is attached as a PDF. I'd welcome the chance to talk at whatever time works for your team.

Best regards,

Megan Alvarez

Six lines, one number, the two tools the posting asked for, and nothing else. If the posting also asked for a cover letter or salary expectations, add one line for each, without expanding.

Example: cold application email

When there is no posting, the email has an additional job: explaining why this company is being contacted at all. The person receiving it is not looking for anyone, so the message has to justify its own reading in the first sentence and show that the sender understands the business.

Subject: Inquiry: Industrial Maintenance Technician opportunities - Robert Keller

Dear Mr. Ferreira,

I'm reaching out because Great Lakes Metalworks is expanding its Toledo plant, as announced on LinkedIn last month, and an expansion of that size usually calls for maintenance staff with experience on automated lines.

I'm an electromechanical technician with seven years in preventive and corrective maintenance on production lines; in my current role we cut unplanned downtime by 30% over two years. I'm available for rotating shifts.

My resume is attached. If you open a search in the area over the coming months, I'd be interested in being considered, and in any case I appreciate your time.

Sincerely,

Robert Keller

A cold application should go to a specific person (the head of the department, not the generic HR inbox) and, where possible, come with a more developed letter. How to write one and who to send it to is covered in the guide on the unsolicited cover letter; to draft it in minutes starting from the resume, there is a cover letter generator.

What to check before sending

The short list, which prevents most of the mistakes made in a hurry:

• The destination address, copied from the posting, with no typos.
• The sending address: an account with first and last name. Addresses like "kitten_88" or "bigdawg" get replaced before applying.
• The attachments: that they are there, that they are the right ones, and that they open. Sending an email "with resume attached" and no attachment forces a second email that starts with an apology.
• The recipient's name and the company name, especially if the body was reused from another application.
• The signature: name, phone, and LinkedIn if it adds value. No images, no inspirational quotes.
• Spelling, by reading the whole email once more before sending.

A simple trick against incomplete sends: attach the file first and write the email after. And if the resume will be sent many times, it is worth building it with a tool that exports a clean PDF, so the formatting problem does not repeat with every send.

Mistakes that undo a good resume

A strong resume can still be ignored because of how it arrived. These mistakes happen in the email itself, before anyone opens the attachment, and each one costs a candidacy that was otherwise competitive.

1. Sending the resume with no text in the body. An attachment with no message looks like a mass mailing, and spam filters sometimes catch it.
2. Pasting the full resume into the body in addition to attaching it. It duplicates and clutters.
3. Copying several companies on the same email. It shows, and it disqualifies the sender with all of them.
4. Sending a Word file or a photo of the resume. It opens badly or not at all.
5. Replying from the phone with the automatic signature ("Sent from my iPhone") and autocorrect errors.
6. Writing to the general inbox when the posting names another one. The email reaches someone who cannot act on it.
7. Following up after two days. A follow-up makes sense after one or two weeks, and with a brief message.
