The posting is open in one tab and your half finished letter is in the other. The sentences are not what stopped you. The top of the page is. Your address or no address, today's date or no date, the company's mailing address above the greeting or nothing there at all. You looked up cover letter format in three places and got three different answers about what belongs at the top.
The three answers all make sense, because they describe three different situations. Most templates teach a letter that is printed, folded, and mailed, and that letter needs a header, a date, and a recipient address for reasons that no longer apply to you. Your letter is going out as a PDF attached to an application, as the body of an email, or as text typed into a box on a company's form. The same six blocks behave differently in each one, and many templates do not tell you which ones to drop.
This article takes the letter apart block by block and gives you a table that says keep it, rewrite it, or cut it for each of the three ways a letter gets delivered. Then the same letter appears three times, annotated, so you can see the difference instead of reading about it. If you have not written the letter yet and you need the writing process rather than the layout, start with how to write a cover letter and come back with a draft.
Quick answer: A cover letter has six blocks: contact header, date and recipient line, greeting, opening, body, closing and sign off. All six belong in a PDF. In an email body, the header moves under your name as a signature and the date and recipient line disappears into the subject line. In an application text box, the header, date, and recipient line all come out, because the box strips your formatting and the reader may see only the words.
People pack three separate questions into the word format, then get frustrated when one answer does not cover all three.
The first question is structural: which blocks the letter contains and what order they sit in. The second is visual: margins, font, size, spacing, alignment, length, file name. The third is the one almost nobody asks out loud: how the letter physically reaches the person who reads it.
The third question governs the first two. A PDF keeps the page you built. An email body keeps some of it. A text box on an application form keeps your words and very little else. So there is no single proper cover letter format that works everywhere, only a correct format for the channel you are submitting through.
Use this to skip ahead. If you want to know which blocks exist and what they do, read the next section. If you already know the blocks and want the decision for your channel, jump to the keep, rewrite, or cut table. If your question is really about margins and fonts, the layout section near the end answers that and nothing else.
Every cover letter outline you have seen is some version of the same six blocks, top to bottom. What the templates leave out is the job each block does, which is the only way to tell whether you can drop it.
| Block | The one job it does | What breaks it |
|---|---|---|
| Contact header | Puts your name and a working way to reach you at the top | Your name set smaller than your address, so the page announces a street instead of a person |
| Date and recipient line | Places the letter in time and names the destination | A date that contradicts the day you actually send it |
| Greeting | Opens the conversation with a specific human or team | To Whom It May Concern, which tells the reader you did not look |
| Opening | Names the role and gives one reason to keep reading | Two lines spent on how excited you are about the opportunity |
| Body | Shows evidence the resume does not already show | A retelling of your resume in paragraph form |
| Closing and sign off | States the next step and leaves your contact behind | Trailing off with a thank you and no name attached |
Read the middle column as a test. If a block still does its job in your channel, keep it. If something else is already doing that job, such as a subject line naming the role, the block is redundant. That is the logic behind the cover letter sections you keep and the ones you delete.
This is the question under most of the frustration. You fill in a form, attach a file, press submit, and you have no way to know whether a human opens it. Nobody can tell you exactly what happens inside a given company, and any guide that claims to describe the internal route of your application is guessing. What you can do is plan for three plausible scenarios.
A file attached to an application may sit on your candidate record next to your resume, waiting for someone to open it deliberately. It may get opened after the resume, or not at all, depending on how that team works. That is an argument for a letter that survives a quick look.
An email lands in a person's inbox and can be read on a phone, where the subject line and the first lines may be visible before anything is opened. Those lines carry the letter.
Text pasted into a form field may be displayed without your spacing, fonts, or indents, sometimes beside the resume text and sometimes behind a click. There the layout is not yours anymore, so the meaning has to survive in the words alone.
Find your channel, read the column, apply the six decisions. Everything after this section explains the reasoning behind the cells.
| Block | PDF attachment | Email body | Application text box |
|---|---|---|---|
| Contact header | Keep. The page stands alone, so it needs your name on it | Rewrite. Move it under your name as a signature block | Cut. Four stray lines above the greeting, and the form already has your details |
| Date and recipient line | Keep, optional. Harmless on a formal page | Cut. Role and job ID belong in the subject line | Cut. There is no page and no date to place |
| Greeting | Keep | Keep | Keep |
| Opening | Keep | Keep | Keep, shorter. Front load the role and the reason |
| Body | Keep, two paragraphs | Rewrite. Shorter paragraphs, four lines maximum on a phone | Rewrite. Two paragraphs compress into one, and the company specific reason goes first |
| Closing and sign off | Keep. Name only under the close | Keep. Name plus phone and email in the signature | Rewrite. Name and one contact detail on a single line |
Two notes that the table cannot hold. Length shifts down as you move right across the columns, since a page tolerates more than an inbox and an inbox tolerates more than a form field. Word counts are their own question, handled in how long should a cover letter be. And if the form field is your channel, the mechanics of stripping a letter down to clean plain text are covered in plain text cover letter.
Here is the same hypothetical letter three times. The applicant is a customer support specialist applying to a software company, and the names, company, and job ID are placeholders. No argument changes between the versions. Only the layout does.

Hiring Team, [Company]
Dear [Hiring Manager Name],
I am applying for the Customer Support Specialist role, job ID [12345]. I have spent two years on billing and access issues for a subscription product, the same queue your posting describes.
Your posting asks for shared inbox experience and help center writing. I worked a queue of about forty tickets a day and rewrote the eight articles that drove the most repeat contacts, which cut follow up questions on those topics.
I am applying to [Company] because your support team publishes its own documentation instead of routing everything to engineering.
I would be glad to walk through the documentation samples in an interview.
Sincerely, Alex Rivera
Blocks present: all six. The sign off is just a name, because the header already gave the contact details.
Subject: Customer Support Specialist, job ID [12345], Alex Rivera

Dear [Hiring Manager Name],
I am applying for the Customer Support Specialist role, job ID [12345]. Your posting asks for shared inbox experience and help center writing. I handled about forty tickets a day for a subscription product and rewrote the eight articles behind the most repeat contacts. I am applying to [Company] because your support team publishes its own documentation instead of routing everything to engineering.
Happy to share documentation samples. Alex Rivera, 555 0100.
Blocks changed: header, date, and recipient line are gone, the two body paragraphs merged into one, and the sign off is a single line. The words did the work because nothing else could.
The header is the block that causes the most confusion, and the reason is historical. It exists because a letter used to travel in an envelope and needed a return address. Your letter travels as a file, a message, or a form field, so the header keeps only the part that still has a job.
Keep in the contact line: your name, your city and state, your phone number, your email address, and one link if a portfolio or profile is relevant. Set your name larger than everything else so the eye lands on a person. Match the name, phone, and email exactly to your resume, because a reader holding both documents should not have to reconcile two versions of you.
Cut from the header: your full street address unless the posting asks for it, since nothing is being mailed anywhere. Cut the employer's mailing address block entirely. Cut the date from anything that arrives instantly, because a date that disagrees with the timestamp is the kind of contradiction that makes a careful reader pause.
A reference line such as Re: [Role title], Job ID [number] under the greeting is optional and useful in a PDF, where nothing else carries that information. In an email the subject line does that job, so the reference line is duplication.
The greeting stays in all three channels. Who to name when the posting hides the hiring manager, what to do with committees and agencies, and which fallback greeting to use when no name exists are handled in how to address a cover letter.
The opening has one job in every channel, and about two lines to do it, because in an inbox or a form preview two lines may be all that shows before the reader decides to keep going.
Those lines establish three things: which role this is about, including the job ID if the posting has one, why you are writing to this employer, and one concrete reason to consider you a plausible fit. An opening of I am writing to apply for the position of spends its most valuable space announcing that you sent an application, which the reader already knows.
Weak: I am writing to express my interest in the Customer Support Specialist position I saw advertised on your careers page.
Rewritten: I am applying for the Customer Support Specialist role, job ID [12345]. I have spent two years on billing and access tickets for a subscription product, which is the queue your posting describes.
One comparison is the limit here, because opening lines have their own catalog. If you want thirty first lines sorted by situation, including referrals, career changes, and gaps, use cover letter opening lines.
The body often fails when it restates the resume in sentences. A reader with both documents open gets nothing new, so the letter becomes a slower version of a page they already have.
The first body paragraph matches two or three requirements from the posting and adds evidence the resume does not carry, or carries in one compressed line. The second gives the context a resume cannot hold: why this company, a change of direction, a gap, a relocation. In a text box the two compress into one, and the company specific sentence goes first, because it is the part no other applicant can copy.
Four things that do not belong in the body:
The closing is three lines, and each has a job. Name one clear next step. Thank the reader once, plainly. Sign with your name and, depending on the channel, a contact detail.
Asking for an interview at the end can feel like it undoes the tone you built above. A closing does not ask for a favor. It names the next action in a process the reader already runs, which is why a line like I would be glad to walk through the documentation samples in an interview reads as normal rather than pushy.
The sign off follows the channel. In a PDF, your name under the close is enough, since the header carried your contact details. In an email, your name plus phone and email. In a text box, your name and one contact detail on one line. No handwritten signature and no Enclosure line in any of the three, since neither has anything to refer to. Closing sentences you can adapt are collected in cover letter closing lines.
This is the visual half of the word format. It applies fully to a PDF, partly to an email, and not at all to a text box. The font question has a simple rule: use a standard readable font, ideally the one already on your resume.
| Setting | What to use | Why it matters |
|---|---|---|
| Margins | One inch, 0.75 inch as the minimum | Text that runs to the paper edge is harder to read on screen |
| Font | Any standard readable face, the same one as your resume | Two documents in one font look like one application |
| Size | 11 to 12 pt | Smaller sizes push readers to zoom |
| Line spacing | Single, with a blank line between paragraphs | Blank lines are what make paragraphs visible |
| Alignment | Left, no justification | Justified text opens uneven gaps between words |
| Length | One page | One page keeps the main argument easy to scan |
| File name | Firstname-Lastname-Cover-Letter.pdf | Your name is visible in a folder of attachments |
These numbers are conventions rather than findings. They exist because they read well on a screen and because a page set this way looks the same to the reader as it does to you. Two things to avoid in a letter that may be parsed or converted: content inside tables and content in headers or footers, both of which can be lost or displaced when a document is processed. Setting this up in an editor and exporting it cleanly is covered in cover letter template for Word and Google Docs.
A letter built on the paper model can look perfect on your screen and arrive damaged. Here is a letter written for print, pasted into an application text box.
Alex Rivera 1234 Example Street Austin, TX 78701 March 4, 2026 [Hiring Manager Name] [Company], 500 Example Ave Dear Sir or Madam, • Two years of customer support experience Enclosure: Resume
Four lines of address now sit above the greeting where the opening should be. The date contradicts the day the form was submitted. The bullet character may render as a stray symbol or vanish. The Enclosure line points at an attachment that does not exist in a text field. The same letter, rebuilt for the channel:
Dear [Hiring Manager Name],
I am applying for the Customer Support Specialist role, job ID [12345]. I spent two years on billing and access tickets for a subscription product, the same queue your posting describes.
Your posting asks for shared inbox experience and help center writing, and I rewrote the eight articles behind our most repeated questions.
Alex Rivera, 555 0100
| What was there | What replaces it |
|---|---|
| Address block and date | Nothing, the form holds your details |
| Formal salutation to no one | Greeting with a name, or a team name |
| Bullet list | The same facts in a sentence |
| Enclosure line | Nothing |
Breakages you cannot see in the other two channels: a PDF exported at the wrong page size, which can make the page harder to view or print cleanly, a file name that shows up as document-final-2 in a folder of attachments, an email whose formatting is stripped by the recipient's client, and pasted text carrying invisible line breaks that split sentences in the middle. A final check takes a minute. Open the finished file fresh, or paste the text into a plain text editor and read it before it goes into the form.
In a PDF, a date is optional and harmless. In an email or a text box, both belong to the paper version of the format and should come out. Nothing is delivered by mail, and a date that disagrees with the submission timestamp only creates a contradiction.
Send the format the posting asks for, and choose PDF when the instructions are silent, because it preserves the page layout better than pasted text.
Four in a PDF: opening, two body paragraphs, closing. Three in an email, with shorter paragraphs. One or two in a text box, where the body compresses. Total word count is a separate question with its own tradeoffs.
No header and no date. The subject line carries the role and job ID, the greeting comes first, the paragraphs run shorter than they would on a page, and your contact details sit under your name as a signature.
The structure does not change. If you submit a letter, submit a complete one with the blocks your channel needs. If the form requires a letter, it has to be readable, which is the narrow argument here.
This article describes United States practice. Other countries have their own conventions about photos, personal details, and signatures, so check local expectations before reusing this layout abroad.
No. A scanned signature adds nothing to a PDF, cannot exist in an email body or a text box, and can render as a broken image. Your typed name is the sign off in all three channels.
