How to open a cover letter without wasting the first sentence

The reader already knows you want the job. The opening has to carry something they did not know, and it has about two sentences to do it in.

— the first line is the only one everyone reads.

The opening as the builder drafts it, for an invented candidate applying to an invented company: the role and company, one sentence of who you are, and the strongest proof.

The opening of a cover letter is the sentence most likely to be read and least likely to be written carefully. It usually arrives as some version of "I am writing to apply for the position advertised on your website", which is true, and which the reader had already worked out from the letter in front of them.

The test for an opening is simple. Delete it. If the letter reads the same without it, the sentence was not carrying anything.

What the opening has to do

  • Name the role exactly. Employers run several vacancies at once. A letter that does not say which one has made a filing problem out of an application.
  • Name the employer. Once, correctly spelled. A letter with another company's name in it is the only mistake in this document that is fatal on sight.
  • Carry one real thing. The reason this employer, or the single piece of evidence that makes the rest of the letter worth reading.

That is all. Three jobs, two sentences, and then the proof paragraphs take over.

Three registers, one job

Openings come in roughly three registers. Direct says the thing: "I'm applying for the Payments Platform Engineer role at Vantorel." Warm adds a person to it: "I'd love to bring my work on payment systems to the Payments Platform Engineer role at Vantorel." Formal is conventional correspondence: "I am writing to apply for the position of Payments Platform Engineer." Choose by the employer's own register, which the posting usually shows you: a bank's advert and a start-up's advert are not written in the same voice, and your letter should not be either.

Whichever you pick, the register changes the wording and never the claim. It does not add a skill, hide a gap or make a piece of evidence sound larger than it is.

What the builder drafts

The cover letter builder drafts the opening in the direct register. It names the role and the company you entered, adds the first sentence of your own summary in the first person, and then the line of your résumé that answers the posting best: "Here is the work I would bring to it: I rebuilt the settlement pipeline, cutting end-of-day reconciliation from 40 minutes to 6." The Opening paragraph is editable like every other, so a warmer or more formal first line is yours to write.

Openings that work

Three shapes carry their weight. The first names the role and attaches the single strongest result you have: you are applying for the settlement role, and you rebuilt a settlement pipeline. The second names the role and one specific thing about the employer that you could not have written about anyone else. The third, for an internal move, names the role and says you already work there, which changes the whole reading of the letter and is covered on the internal application page.

What the three have in common is that they are checkable. Someone could ask you about any of them and you would have an answer. An opening for a change of career has one more job again, which is to name the change before the reader has to work it out.

Openings that cost you

The dictionary opening, where the letter begins by defining a quality. The mirror opening, which restates the posting back to the employer. The superlative opening, which claims to be the ideal candidate before any evidence has been offered. Each one spends the most valuable sentence in the letter on nothing, and a reader who has opened forty letters that morning has seen all three.

There is a fourth, quieter failure: the opening that promises something the rest of the letter does not deliver. If the first line says you transformed a department, the proof paragraphs have to show the department. Otherwise the letter has argued against itself by the third paragraph.

Where the opening comes from

If nothing obvious presents itself, the opening is usually already written somewhere in your evidence. The strongest line in your experience bullets, the one with a number in it, is a candidate. So is the summary at the top of your résumé, which is the same argument at a different length; the summary page covers how to make that line earn its place.

What is not a source is invention. If you cannot find the reason this employer, leave the reason out and let the evidence carry the letter. A letter that is honestly cold reads better than one that is warmly false.

Then stop

Once the role, the employer and the one real thing are on the page, the opening is finished. Everything else belongs in the proof paragraphs, where a reader expects it and where each claim can be traced back to a line of your résumé.

Write it last

The opening is the hardest sentence in the letter and the one people write first, which is why so many of them are placeholders that survived to the send button. Write the proof paragraphs, then read them back and ask which of them a reader should meet first. The opening is usually a compressed version of that paragraph, and by then you know what it says.

Doing it in that order also removes the blank-page problem. There is nothing harder than opening a letter you have not written yet, and nothing easier than opening one you have.

Draft the opening from your own résumé

Paste the posting and connect your résumé: the opening names the role and company, then the line of your evidence that answers the posting best.

Questions

Should I open with "I am writing to apply for"
It is the classic formal opening and it is perfectly serviceable. It spends a sentence on something the reader already knows, which is a cost worth paying only when the register of the employer calls for it.
Can I open with a story
You can, and it is a risk. A story that takes three sentences to reach its point has spent the part of the letter that is certain to be read. One sentence of story followed by the result is the version that survives.
Does the builder write the opening
It drafts it from the role and company you gave it, the first sentence of your own summary and the line of your résumé that answers the posting best. The Opening paragraph is editable, and the preview updates as you type.
What if I do not know why I want this employer
Then say nothing about it rather than inventing something. The builder never writes a reason for wanting a job; if you have one, add it to the Opening paragraph in your own words. An opening that names the role plainly is better than a paragraph of manufactured enthusiasm.
Is there a right length
Two or three sentences is the working figure. The builder shows each paragraph's word count beside it, and the length of the whole body on the Before you send checklist.
