How to Email a Resume (Subject Line, Body, and What to Attach)

Emailing a resume feels like the trivial part — you've done the hard work already, this is just delivery. But the email is the first thing a hiring manager reads, often on a phone, and a blank message with an attachment named resume-final.docx sets a tone before anyone opens anything. It takes four minutes to get right. Which file to attach is settled in our guide to PDF versus Word, and every layout in our ATS-safe template collection exports cleanly either way; if you're writing a full letter rather than a short note, our guide to writing a cover letter covers that properly. For the other routes into a company, see our guide to adding your resume to LinkedIn, and for the message that comes later, our thank-you email guide. The full job-search collection has the rest.

The subject line

A recruiter's inbox is a search field. Write the subject so that searching for the role finds you:

Application: Senior Data Analyst (Req. 4471) — Jordan Reyes

Role first, reference number if the posting gave one, your name last. That's it. Avoid "Job application," "My CV," "Hello," and anything that reads as a greeting rather than a label. If someone referred you, that's the one thing worth adding, because it changes how the message gets read:

Referred by Priya Nandakumar — Senior Data Analyst (Req. 4471) — Jordan Reyes

The body

Short. Five or six lines. The email is not the cover letter; it's the note that comes with it.

Hello Ms. Achebe,

I'm applying for the Senior Data Analyst position (Req. 4471). I've spent the last four years building reporting pipelines for a mid-size logistics company, most recently cutting our month-end close from nine days to two.

My resume and cover letter are attached. I'd welcome the chance to talk about the role.

Best regards, Jordan Reyes +1 555 019 8823 · [email protected]

Four things are doing work there. It names the exact role. It gives one concrete piece of evidence rather than adjectives. It says what's attached. And it repeats the contact details in the body, so nobody has to open the attachment to find your phone number.

Address a person if you can find one. "Dear Hiring Manager" is acceptable and far better than "To Whom It May Concern," which reads like a form letter from 1994.

The attachment

Attach the file before you write the email. Almost every "sorry — attaching now" follow-up comes from doing this last, and that second email is what the recruiter remembers.

Name it properly. Jordan-Reyes-Resume.pdf, not resume-final-v4.pdf. It's going into a folder with hundreds of others, and yours should be identifiable at a glance.

Send PDF unless told otherwise, for the layout reasons covered in the format guide.

Keep it under about 5 MB. Some corporate mail gateways silently reject larger attachments, and you'll never be told.

Never send a link instead of a file unless asked. Cloud links expire, require permissions, and get blocked by corporate security. Attach the actual document.

Before you press send

• Send it to yourself first and open it on your phone. That's how it will be read.
• Check the company name. Reusing a previous email and forgetting to change it is the single most common fatal error here.
• Check the attachment is the tailored version, not last week's.
• Send during business hours in the employer's timezone if you can. It doesn't matter enormously, but a 3am timestamp is a small unforced oddity.

Following up

If the posting gives a decision timeline, wait for it. Otherwise, one follow-up after seven to ten working days is reasonable — a short reply to your original message, so the whole thread stays together. One follow-up, not three.

Frequently asked questions

Should I paste my cover letter into the email body? If the posting doesn't ask for a separate letter, yes — a slightly longer email body works better than an attachment nobody opens. If it asks for a cover letter as a document, attach it as a document and keep the email short.

What if I can't find anyone's name? "Dear Hiring Manager" is fine. Check the posting, the company's team page, and LinkedIn first, but don't spend an hour on it or guess wrong — a misspelled name is worse than a neutral greeting.

Should I email a resume if the posting says to use the online portal? Use the portal. Emailing around a stated process reads as not following instructions, and the portal is usually what feeds the applicant tracking system that the hiring team actually works from.

Is it worth emailing the hiring manager directly as well as applying? Occasionally, and only if you have something genuine to add — a specific question about the role, a relevant piece of work. A duplicate application sent to a second address is just noise.

How large is too large? Under 5 MB is safe. A text-based resume PDF is normally well under 1 MB; if yours is several megabytes, it almost certainly contains an embedded image, which is worth checking for parsing reasons anyway.
