Someone asked for a cover letter and you're not sure if that means a casual email or a real formal letter with a date block and Dear Hiring Manager. You haven't written block format since school and you're worried you'll look stiff or, worse, sloppy. You're not alone. Most job seekers guess at structure and lose callbacks on formatting before a recruiter reads sentence two.
I've read thousands of cover letters in Greenhouse and Workday. Formal letter structure still matters when you upload a PDF or paste into a text box that preserves line breaks. You don't need Victorian prose. You need the right blocks in the right order with role, proof, and a clean close. Before you draft tonight, check your resume for free against the posting so your letter matches what page one already claims.
This guide shows how to write a formal letter for US job applications: heading, inside address, salutation, body paragraphs, closing, copy-paste templates, and mistakes that make recruiters stop reading.
Quick Wins
- Use block format: left-aligned contact, date, employer address, salutation, body, close.
- Keep cover letter bodies to three or four short paragraphs, one page max.
- End with Best regards, typed name, and Enclosure: Resume when uploading PDF.
What counts as a formal letter in job applications
A formal letter for hiring is a structured document with standard blocks: your contact information, date, recipient address when known, salutation, body paragraphs, closing phrase, and typed signature line. Cover letters, job application letters, and some follow-up notes use this format in US corporate hiring.
Formal does not mean flowery. It means predictable layout recruiters and ATS paste fields can parse. Single-spaced paragraphs, blank line between sections, 10.5 to 12 point Calibri, Arial, or Times New Roman, one-inch margins on PDF uploads.
Email applications can use a shortened version: greeting, body, sign-off, but many portals still ask for a letter file or paste box that expects block structure with line breaks preserved.
Recruiter filter: When a cover letter jumps straight to I am writing without a date or salutation and the portal asked for a formal letter upload, I assume you pasted an email draft and didn't read instructions.
Read how do you start a cover letter, how to end a cover letter, and how to start a cover letter for opener and closer detail once the block format is set.
The difference between a formal letter and a casual note is layout, not vocabulary. You can write I reduced churn by 14 percent in paragraph two and still be formal if the blocks are correct and the tone stays professional. Recruiters scan structure first, then proof, then whether you followed upload instructions.
Job application letters, cover letters, and some post-interview thank-you notes all share the same skeleton. What changes is the body goal: apply, explain a gap, accept an offer, or confirm next steps. Keep one purpose per letter. Do not combine salary negotiation and cover letter content in one formal upload unless the posting asks for it.
When a posting says optional cover letter, treat formal structure as a tiebreaker. Two similar resumes often split on who sent a clean one-page letter with role name and metric in paragraph one. Optional rarely means skip if you want the callback.
How to write a formal letter step by step
Step 1: Write your contact block
Top left: Your full name, street address optional for privacy, city, state, ZIP, phone, email, LinkedIn URL if professional. Use the same contact info as your resume. One blank line, then date written as Month Day, Year.
Match phone format to your resume exactly. If resume shows (555) 123-4567, do not switch to 555.123.4567 in the letter header. Small mismatches trigger manual checks in some HR systems. Date should be the day you submit, not the day you started drafting last week.
Step 2: Add inside address when you have it
Hiring manager name if known, title optional, company name, company street address, city, state ZIP. Skip street if unknown. Company name and city are enough for many online applications. One blank line before salutation.
Step 3: Choose salutation
Dear Ms. Patel, or Dear Hiring Manager, or Dear Analytics Hiring Team,. Use correct title and spelling. Wrong names hurt more than neutral greetings.
Step 4: Draft body paragraphs
Paragraph one: role and company name plus one proof metric from your resume. Paragraph two: tie experience to posting requirements with tools and outcomes. Paragraph three: one specific detail about team or product plus closing ask for interview. Three paragraphs beat five short ones.
Open paragraph one with I am writing to apply for or I am applying for, then the exact job title from the posting. Copy the title string from the req, not a shortened version you prefer. ATS and recruiter filters often search that phrase when they batch-read cover letters for one role.
Paragraph two is where you mirror two to three posting keywords with proof. If the req lists Salesforce, SQL, and stakeholder reporting, pick the pair you can defend with numbers and name the tools plainly. No bullet list inside the letter body unless the posting asks for one.
Paragraph three closes the sale: one sentence on why this team or product, one sentence on availability, no apology language. I welcome the chance to discuss how my experience in X supports your Y initiative beats I hope you will consider my application, which sounds passive in formal letters.
Step 5: Close and sign
One blank line after body. Best regards, or Sincerely, then four returns or blank space, then typed full name. Optional Enclosure: Resume on its own line when PDF packet includes resume.

Dear Ms. Name,
Paragraph one: I am applying for the [exact title] role at [Company]. In my current role I [metric using tool from posting].

Enclosure: Resume
Composite example: informal email pasted as letter
Before: Hey, wanted to apply for the job. Resume attached. Thanks!
After: Block format with date, Dear Hiring Manager, three paragraphs naming Sr. Analyst role, SQL dashboard metric, and interview availability, Best regards, typed name.
Composite example: stiff but empty formal letter
Before: Perfect block format, no role name, no metrics, four paragraphs of generic praise.
After: Same structure, paragraph one names exact title, paragraph two cites one numbered resume bullet tied to posting keyword.
Edge case: paste box with no address block
Start with Dear Hiring Manager, then body paragraphs. Skip contact block if the portal already captured your info. Keep salutation and closing for readability in recruiter preview panes.
Edge case: referral formal letter
Paragraph one: [Referrer name] suggested I contact you regarding the [title] opening. Then metric and posting tie in paragraphs two and three. Formal structure stays the same.
Edge case: government or academic formal reqs
Some USAJobs and university postings expect full inside address and Sincerely default. Read posting instructions for required headers. Body still needs role, proof, and clear close.
Edge case: startup casual culture
Keep formal block format for PDF uploads even when tone in paragraph one is conversational. Kind regards works. Structure signals you can follow directions on other forms too.
Edge case: career change formal letter
Paragraph one names the target role and one transferable metric from a different field. Paragraph two bridges posting language to prior work without apologizing for the pivot. Formal structure keeps the career change story readable instead of buried in a long email thread recruiters never open.
Edge case: returning after employment gap
Use one sentence in paragraph two if the gap is recent and relevant, then move to current skills and proof. Do not lead with the gap in paragraph one when the role is forward-looking. Formal letters need confidence in block order, not a disclaimer essay.

Dear Hiring Manager,
I am applying for the Marketing Coordinator role at BrightPath Health. At River Clinic I grew email list sign-ups by 22 percent in six months using HubSpot workflows tied to patient education campaigns.
Your posting emphasizes cross-functional campaign support and HIPAA-aware content. I coordinated weekly creative reviews with clinical leads and cut approval cycle time from nine days to four while keeping all assets compliant with internal review rules.
BrightPath's focus on preventive care outreach matches the community health work I want to scale next. I am available for a call Thursday or Friday afternoon and welcome the chance to discuss how I can support your Q4 launch calendar.
Best regards,
Jordan Lee

Formal letter mistakes on job applications
Skipping salutation or date on PDF uploads. Looks like an email fragment, not a letter.
Wrong company or manager name. Copy-paste errors kill trust immediately.
Indented paragraph format from school templates. Block format left-aligned is standard for US business letters now.
Two pages for a cover letter. Formal does not mean long. One page, three or four paragraphs.
Metrics that don't match the resume. Letter and resume must align for recruiter spot checks.
Overly casual sign-offs on formal reqs. Cheers on a bank compliance letter reads off.
Forgetting Enclosure line when resume is attached. Small detail that helps human reviewers sorting PDF packets.
Using fancy fonts and colors. Plain black text, standard font, readable margins only.
Repeating the entire resume in paragraph form. The letter adds context and one or two proofs, not a second resume. Point to the resume with Enclosure and keep body focused.
Salutation with wrong gender or outdated Mrs. guess. Use Ms. when unsure, or switch to team-based greeting when no name is verified.
Uploading Word .docx when PDF is requested. Formatting shifts between machines. Export PDF for formal letter uploads unless the portal specifies otherwise.
Leaving the subject line blank on email plus attachment. When email carries the formal letter PDF, subject should include your name and exact job title so inbox search finds you later.
