Is a cover letter still necessary?

Last updated August 17, 2026

Sometimes. A cover letter that restates your resume in paragraph form is wasted effort on both sides. One that explains something your resume cannot is often the reason you get the interview. The question is not whether to write one — it is whether you have anything to put in it.

The test

Is there something about your application that the resume cannot explain? If yes, write the letter. If no, your time is better spent improving the resume.

Things a resume genuinely cannot explain:

• Why this employer specifically, when the reason is real and not flattery.
• A career change, where the connection between what you did and what you are applying for is not obvious from titles.
• A gap, a relocation, or an unusual path.
• A referral — "Priya Raman suggested I apply" belongs in the first line.
• Applying below your previous level on purpose, which otherwise reads as a mistake.

When it is required

If the posting asks for one, write one. Skipping a stated requirement is read as either carelessness or as not wanting the job much, and both are easy conclusions for a recruiter to reach with a full inbox.

When the field is optional and you have nothing specific to say, leaving it blank is better than filling it with template text. An obviously generic letter is worse than none.

What a good one looks like

Three short paragraphs. Under 250 words. It should be readable in under a minute.

1. Why this role, specifically. Name something concrete about the company or the work. Not "your reputation for innovation" — something you could only say about them.
2. Your single strongest piece of relevant evidence, expanded slightly beyond the resume bullet. One story, told properly, beats a list.
3. The thing the resume cannot say. The gap, the change, the reason you are moving. One or two sentences, no apology.

What makes them bad

• Restating the resume. They already have it. A paragraph version is strictly worse than the bullets.
• Opening with "I am writing to apply for…" They know. Use the first line for something that earns the second.
• Praise that could apply anywhere. "I have long admired your commitment to excellence" tells them you did not look.
• Length. A full page of prose from a stranger does not get read.
• Obvious AI-generated text. Recruiters read hundreds of these and the register is recognisable. Use AI to edit, not to originate — the specifics are the whole value and only you have them.

A worked example

Here is the same applicant, before and after. The first version is what most people send.

The difference is not writing skill. It is that the second one could only have been written by someone who read the posting and has actually done the work.

Where it goes, and what to call it

Applying through a portal with an upload field: attach a PDF named Firstname-Lastname-Cover-Letter.pdf. A file called coverletter_final_v3.pdf arrives in a recruiter's folder alongside fifty others with the same name.

Applying by email: put it in the body of the message and attach only the resume. Making someone open an attachment to read three paragraphs adds a step for no benefit.

If there is a free-text "anything else we should know" box and no cover letter field, that box is the cover letter. Use it, briefly.
