Applying by email is a bit different from uploading to a portal. When you paste your cover letter into the body of an email, first impressions happen fast, and you need to get straight to the point without skipping the substance.
Subject Line Matters More Than You Think
Your subject line is the first thing a recruiter sees. Keep it simple and specific: “Application for Marketing Manager, Ref #1234, Jane Smith.” Avoid vague subjects like “Job Application” or “Inquiry.” Recruiters sort through dozens of emails daily, and a clear subject line immediately tells them what to do with your message.
Start With Your Strongest Sentence
Skip “I am writing to apply for…” and lead with something that shows you know the company or role. Something like, “Your recent campaign on sustainable packaging caught my attention, and I have spent the last three years building exactly the kind of brand story you are looking for.” That first sentence is everything. For more on this, see our guide on cover letter vs. no cover letter.
Keep the Body Short, Three to Four Paragraphs
Email cover letters should be tighter than portal submissions. Three short paragraphs work best: why you are interested, what you bring, and a clear ask. Long emails feel like a wall of text on a phone screen, and that is where most recruiters read them these days.
Attach Your Resume With a Clear Filename
Name your attachment something like “FirstName-LastName-Resume.pdf” not “Resume_v3_FINAL.docx.” Recruiters download dozens of resumes and a clearly named file makes their job easier, which creates a small but real positive impression of you.
Follow Up Within Five Business Days
If you do not hear back in five business days, a single polite follow-up is completely appropriate. Something brief: “I wanted to confirm you received my application for the Marketing Manager role and to reiterate my interest.” Short, professional, not desperate. For more on this, see our guide on write an internship cover letter that stands out.

Frequently Asked Questions
Should I always include a cover letter?
Include one when requested, when writing ability is core to the role, or when you need to explain context your resume cannot. For high-volume technical roles, it is often not read.
How long should a cover letter be?
Three to four short paragraphs, 200-300 words maximum. If you are writing more, you are probably repeating your resume.
What should the first sentence of a cover letter say?
Start with something specific. “I have spent four years doing exactly what this role requires” beats “I am excited to apply for this position.”
What should I leave out of a cover letter?
Do not restate your resume, explain why you need the job, apologize for gaps, or use clichés. Every sentence should add information not already in the resume.
Most cover letters fail because they summarize the resume rather than add to it. A recruiter reading your cover letter already has your resume in hand. They do not need you to recap it. What they want to know is why this role, at this company, is one you are genuinely excited about, and what specific experience makes you a stronger candidate than the other 150 applicants who also ticked all the required boxes.
The best cover letters I have seen treat the format like a brief business proposal. They open with a specific observation about the company or role, connect that observation to a relevant achievement, and close with a clear next step. This structure respects the hiring manager’s time while demonstrating that you have done real research rather than sending a mass application.
Length matters here, too. A cover letter should be between three and four paragraphs. Any shorter and it feels dismissive of the opportunity. Any longer and you are asking a busy hiring manager to read a document they typically spend less than thirty seconds on. Every sentence should either demonstrate fit, show enthusiasm, or move the reader closer to wanting to meet you. For more on this, see our guide on write a career change cover letter that works.
Get your free resume review from a real recruiter
At AskTheRecruiter.com, every resume review is done by a human recruiter with years of hiring experience. You’ll get honest, specific feedback you can act on right away. No automated scoring, no generic tips.
Anonymous and approximate. We store one number for this article and nothing about you.
Email digest
We also run a layoff tracker, built from company filings and official notices. A plain email summary of what changed on these trackers: headline numbers, the largest new entries, and links to the sources. You confirm your address by clicking a link we email you, and one click unsubscribes. Already subscribed? Use this form to change what you get. The boxes replace what you had.
Our mail provider records whether you open an email and which links you follow, including the confirmation email, which is measured before you have agreed to anything. Unsubscribing stops the sending and the recording together.
You can read every past edition first. Each one is kept permanently, exactly as it was sent.
Privacy note: what we store and how to erase it
What we store: your email address, the choices above, and timestamps (signed up, confirmed, last sent). Nothing else about you.
What our mail provider records: whether you opened an email and which links you followed, tied to your address. That is Brevo, the service that delivers these emails, and it works by adding a small invisible image and by routing links through its own address. We read it to see which sections people use. Unsubscribing stops the sending and the measuring at the same time, and erasing your row removes it from our side.
The confirmation email is measured too: the same invisible image is in the one message that asks your permission. If you open it, Brevo records that against your address before you have agreed to anything, and it records it even if you then never confirm. We would exempt that message if we could. Brevo offers no way to switch its measuring off for a single email, and the one setting that exists covers every email we send or none of them. If you would rather not be measured at all, do not open it. Nothing else is ever sent to an unconfirmed address, and the signup is deleted from our side after 30 days.
About the links: links in the digest pass through a counter on this site that adds 1 to a total for that link and sends you straight on. It records no identifier, no IP address and no browser details, so it counts how many times a link was followed and can never say who followed it.
What it is used for: sending you exactly the emails you ticked, nothing else. The address is never shared, sold, or used for any other purpose.
How to erase it: click the unsubscribe link in any email. That stops all sending immediately, and unsubscribed addresses, along with signups that were never confirmed, are hard-deleted automatically after 30 days. You can also ask via the contact page.
