Business letters remain a key part of professional communication today. They help people and companies share important information in a clear, formal way. Learning how to format business letters properly and using the right phrases can make your messages more effective and help you achieve your professional goals.
Part 1Key Components of a Business Letter
Sender’s Address and Contact Information
The top of a business letter starts with your contact details. This information helps the recipient know who sent the letter and how to respond.
You can include your:
- Full name
- Company name (if applicable)
- Street address
- City, state, and zip code
- Phone number
- Email address
Some companies use letterhead that already contains this information. In that case, you may only need to add the date below the letterhead.
The date should appear after your address with the month spelled out completely. For example: May 6, 2025.
Many professionals also add the recipient’s address below the date. This block should include the person’s name, job title, company name, and full address.
If your correspondence crosses borders, keep date formats in mind. In the United States, letters typically list the month before the day (May 6, 2025), while most other countries list the day first (6 May 2025). Writing the month out in full avoids confusion, since a date like “05/06/2025” could mean either May 6 or June 5 depending on the reader’s location.
If you’re sending a letter on company letterhead, avoid repeating your address a second time above the date. The letterhead already identifies you, so simply add the date and, if needed, the recipient’s address block below it.
Salutation and Greeting Phrases
The greeting sets the tone for your letter and acknowledges the recipient properly.
Common salutation examples:
- “Dear Mr. Johnson,”
- “Dear Ms. Williams,”
- “Dear Dr. Smith,”
- “Dear Professor Garcia,”
- “Dear Hiring Manager,”
- “Dear Customer Service Team,”
- “Dear Human Resources Department,”
- “Dear Sir or Madam,”
- “To Whom It May Concern:”
- “Dear Selection Committee:”
When possible, address the person by name. This personal touch shows attention to detail.
If you don’t know the recipient’s gender, use their full name instead of a title.
Once you have an established working relationship, a slightly less formal greeting can feel more natural without losing professionalism. “Dear Jane,” or “Hello Jane,” works well for colleagues, long-term clients, or vendors you email or write to regularly. Reserve titles and last names for first contact, formal disputes, legal correspondence, or communication with senior executives you have not met.
Main Point and Supporting Details
The body of your letter communicates your message clearly and concisely. Start with a brief introduction that states your purpose.
The first paragraph should get right to the point. Tell the reader why you’re writing in one or two sentences.
Supporting paragraphs provide additional information, evidence, or explanation. Keep each paragraph focused on a single idea.
You might want to use bullet points for lists or to highlight important information:
• They make information easier to scan
• They organize related points
• They break up dense text
A few habits separate a clear business letter from a confusing one:
- Favor active voice over passive voice. “We reviewed your application” reads more directly than “Your application was reviewed by us.”
- Keep sentences under 20 words when possible so the reader does not have to reread them to follow your meaning.
- Limit each paragraph to three or four sentences. Long unbroken paragraphs discourage readers and bury your key message.
- Avoid jargon or internal shorthand the recipient may not recognize, especially in letters going to customers or outside organizations.
Closing Paragraph and Complimentary Closing
The final paragraph should summarize your main points and include a call to action if needed. Keep it brief but clear.
You can mention:
- What you want the reader to do next
- When you need a response
- How to contact you for questions
- A simple thank you for their time
After the closing paragraph, add a complimentary close followed by your signature.
Popular closing phrases include:
- “Sincerely,”
- “Respectfully,”
- “Best regards,”
- “Kind regards,”
- “Yours truly,”
- “Thank you,”
- “Cordially,”
- “Warm regards,”
- “Best wishes,”
Leave four blank lines between your complimentary close and your typed name. This gives you room for a handwritten signature on a printed letter. Under your typed name, add your job title and, if the recipient may not otherwise know how to reach you, your phone number or email address on a separate line. For letters sent as PDFs or through email, a scanned signature or a typed name alone is generally acceptable, since the recipient understands no ink signature is expected on a digital document.
Part 2Business Letter Format and Language
Standard Business Letter
A standard business letter helps you communicate with other businesses or organizations. You might use this format when making inquiries, responding to requests, or sharing important information.
A typical business letter includes:
- Date (at the top)
- Recipient’s address
- Salutation (“Dear Mr./Ms. [Last Name]:”)
- Body paragraphs
- Closing (“Sincerely,” or “Regards,”)
- Signature
- Your printed name and title
Example phrases for standard business letters:
- “Thank you for your prompt response to our inquiry.”
- “In reference to our telephone conversation yesterday…”
- “Please find enclosed the documents you requested.”
- “We are writing to inform you about (…)”
- “I am pleased to confirm our meeting scheduled for next week.”
- “After careful consideration of your proposal…”
- “We regret to inform you that we cannot accommodate your request.”
- “Your feedback is valuable to our ongoing improvement efforts.”
- “As discussed in our previous correspondence…”
- “We look forward to establishing a mutually beneficial relationship.”
- “Could you please provide additional information about…”
- “This letter serves as formal notification of…”
- “We acknowledge receipt of your payment dated April 28, 2026.”
- “Should you have any questions, please do not hesitate to contact me.”
- “We will require your response no later than May 20, 2026.”
- “Our records indicate that your account remains unpaid.”
- “We would like to express our sincere appreciation for…”
- “This matter requires your immediate attention.”
- “We are committed to resolving this issue promptly.”
Full Block, Modified Block, and Semi-Block Formats
The words and phrases in a business letter matter, and so does how they are arranged on the page. Three layout styles cover nearly every business letter you will write or receive:
- Full block format: Every element, including the date, salutation, body paragraphs, closing, and signature block, is aligned to the left margin. Paragraphs are separated by a blank line rather than an indent. This is the most common format in modern business correspondence because it is quick to type and easy to read.
- Modified block format: The body paragraphs stay left-aligned, but the date, complimentary close, and signature are shifted to start at or near the center of the page. This style is common in more traditional industries such as law and finance.
- Semi-block format: Similar to modified block, but each paragraph’s first line is indented rather than separated by blank lines. It is used less often today but still appears in some formal or ceremonial correspondence.
If you’re unsure which style to use, full block format is a reasonable default for most business correspondence, since it looks clean on both printed pages and PDF attachments.
Fonts, Margins, and Spacing Guidelines
Formatting choices that seem minor, such as font and spacing, influence how professional a letter appears before the reader even absorbs the content.
- Use a standard, easy-to-read font such as Times New Roman, Arial, or Calibri, sized between 10 and 12 points.
- Set margins to one inch on all sides. Most word processors default to this setting, so it usually needs no adjustment.
- Single-space the body text and leave one blank line between paragraphs instead of indenting the first line, unless you are following semi-block format.
- Align all text to the left margin. Business letters do not use justified or centered text for body paragraphs.
- Print on standard letter-size paper (8.5 x 11 inches) in the United States, or A4 paper in most other regions, if the letter will be mailed.
Part 3Common Types of Business Letters
The standard format applies broadly, but the tone and phrasing shift depending on why you’re writing. Recognizing which type of letter you need helps you choose language that fits the situation.
Cover Letters and Job Application Letters
A cover letter introduces your resume and makes a case for why you fit a specific role. It follows standard business letter structure but leans more persuasive than informational.
- “I am writing to apply for the [position] role advertised on [platform].”
- “With [number] years of experience in [field], I am confident I can contribute to your team.”
- “My background in [skill/area] aligns closely with the requirements outlined in your posting.”
- “I would welcome the opportunity to discuss how my experience can benefit [company name].”
Inquiry and Order Letters
Inquiry letters request information, pricing, or availability. Order letters formally request goods or services and confirm terms.
- “I am writing to inquire about the availability of [product/service].”
- “Could you please send a current price list and product catalog?”
- “We would like to place an order for [quantity] units of [item].”
- “Please confirm the estimated delivery date upon receipt of this order.”
Complaint Letters
Complaint letters describe a problem clearly and request a specific resolution. A calm, factual tone tends to get better results than an emotional one.
- “I am writing to bring to your attention an issue with [product/service].”
- “On [date], I purchased [item], which did not meet the standards described.”
- “I would appreciate a replacement, refund, or repair at your earliest convenience.”
- “I trust this matter will be resolved promptly and to our mutual satisfaction.”
Adjustment and Response Letters
An adjustment letter replies to a complaint. It acknowledges the issue and explains what the company will do about it, whether the outcome is favorable or not.
- “Thank you for bringing this matter to our attention.”
- “We sincerely apologize for the inconvenience this has caused.”
- “We have processed a full refund, which should appear in your account within [timeframe].”
- “After reviewing your claim, we are unable to issue a refund, but we would like to offer [alternative].”
Recommendation and Reference Letters
Recommendation letters vouch for a person’s skills, character, or performance, usually for a job, school application, or professional certification.
- “I am pleased to recommend [name] for the position of [role].”
- “During the [time period] I worked with [name], they consistently demonstrated [quality].”
- “I have no hesitation in recommending [name] for this opportunity.”
- “Please feel free to contact me if you require further information.”
Resignation Letters
A resignation letter formally notifies an employer of your departure. It should state your last working day and remain courteous, even if the reason for leaving is not entirely positive.
- “I am writing to formally resign from my position as [title], effective [date].”
- “Thank you for the opportunities for growth I have had during my time here.”
- “I am happy to assist in training my replacement during this transition.”
- “I wish the company continued success in the future.”
Part 4Essential Example Phrases for Each Section
Opening Phrases for Business Letters
Professional letter openings set the tone for your entire message. They acknowledge the recipient and establish rapport.
Standard salutations include:
- Dear Mr./Ms./Dr. [Last Name],
- To Whom It May Concern,
- Dear [Department] Team,
- Dear Hiring Manager,
- Good morning/afternoon [Name],
For a warm introduction after the salutation:
- Thank you for your recent [inquiry/order/application].
- I am writing regarding the [topic/position/account] we discussed.
- This letter serves as a follow-up to our conversation on [date].
- We appreciate your interest in [product/service/company].
- It was a pleasure speaking with you about [topic] on [date].
Expressing the Main Point
The main point of your letter should appear in the first paragraph. Clear, direct language helps readers understand your purpose quickly.
Common purpose statements include:
- We are pleased to inform you that your application has been accepted.
- This letter confirms our agreement to [specific terms].
- I would like to request [specific item or information].
- We regret to inform you that we cannot approve your request at this time.
- I am writing to express my interest in the [position] advertised on [platform].
When making a request:
Could you please provide the following information by [date]?
We kindly ask that you review the attached documents.
Your prompt attention to this matter would be greatly appreciated.
Providing Supporting Details
Supporting details strengthen your main point with specific information. This section typically makes up the middle paragraphs of your letter.
When explaining reasons:
- The decision was based on [specific factors].
- Our records indicate that [relevant information].
- As discussed in our meeting, [recap of key points].
When providing evidence:
- According to our data, [specific statistics or findings].
- The attached report shows [key information].
For timelines and processes:

Action-oriented closings:
- Please respond by [date] so we can proceed accordingly.
- We look forward to your reply and continued business.
- Feel free to contact us at [phone/email] with any questions.
Appreciation closings:

- We value your business and appreciate your understanding.
- Your continued support means a great deal to our organization.
Standard sign-offs:
- Sincerely,
- Best regards,
- Respectfully,
- Kind regards,
- Yours truly,
Part 5Common Business Letter Mistakes to Avoid
A well-worded letter can still fall flat if small formatting or tone errors distract the reader. These are the mistakes that show up most often, even in otherwise professional correspondence:
- Burying the purpose: Waiting until the second or third paragraph to explain why you’re writing makes the reader work harder than necessary. State your purpose in the opening lines.
- Mismatched formality: Pairing a formal salutation like “To Whom It May Concern” with casual sign-offs or contractions creates an inconsistent tone. Match your greeting, body language, and closing to the same level of formality.
- Overly long paragraphs: Dense blocks of text discourage a full read. Break information into shorter paragraphs or bullet points.
- Vague requests: “Please get back to me soon” leaves room for delay. Specify a date or timeframe whenever a response is needed.
- Skipping the proofread: Typos, misspelled names, and incorrect titles undermine credibility, especially in a first letter to a new contact.
- Inconsistent spacing or alignment: Mixing block and indented paragraph styles within the same letter looks careless. Pick one format and stay with it throughout.
- Forgetting the enclosure notation: If you mention attached documents in the body but leave off the enclosure line, the recipient may not check for them.
Part 6Adding Final Touches to a Business Letter
Using Enclosures and Attachments
When sending additional documents with your letter, note them at the end. After your signature, type “Enclosures” or “Enc.” followed by the number of items included.
You can list each enclosed document for clarity:
- “Enclosures (3): Resume, Reference List, Certificate”
- “Enc. (2): Product Catalog, Order Form”
- “Attachments: Quarterly Report”
- “Enclosures: Contract (2 copies)”
For electronic letters, you might prefer using “Attachments” instead of “Enclosures” when sending files digitally.
This notation helps recipients check that they received all intended documents.
Carbon Copy (CC), Reference Lines, and Typist Initials
A few additional notations appear below the signature block in more formal or interoffice correspondence. You will not need all of them for every letter, but recognizing them helps you read and produce letters that require this level of detail.
- CC (carbon copy): Lists anyone else receiving a copy of the letter, typically listed by name and title. Example: “cc: Maria Chen, Director of Operations”.
- Reference line: Placed near the top of the letter, it identifies a file, invoice, or case number the letter relates to. Example: “Re: Invoice #4471”.
- Typist initials: If someone other than the signer typed the letter, their initials appear in lowercase after the signer’s initials, separated by a colon or slash. Example: “JD/mk”.
Proofreading and Reviewing Before Sending
A final review catches the small errors that undercut an otherwise strong letter. Before sending, check for the following:
- The recipient’s name, title, and company name are spelled correctly.
- Dates, dollar amounts, and reference numbers match your records exactly.
- The salutation and closing tone match throughout the letter.
- Every enclosure mentioned in the body is listed in the enclosure notation, and vice versa.
- The letter fits on one page whenever possible. Business letters that run long often lose the reader’s attention before the key request appears.
- Contact information is current, especially if you’re using a template from a previous letter.
Part 7Business Letters Versus Emails: When to Use Each
Many business communications today happen over email, but a formatted letter still carries advantages in certain situations. Choosing the right format shows an understanding of the situation’s weight.
- Use a formal printed or PDF letter for contracts, official notices, resignation letters, reference letters, and any correspondence that may need to be kept as a permanent record.
- Use email for day-to-day requests, quick updates, and situations where speed matters more than formality.
- When formality and speed both matter, attach a properly formatted business letter as a PDF to a brief email. The email body can include a short note, while the letter itself retains full formatting for printing or filing.
- Keep the tone and structure of an emailed business letter close to its printed counterpart. A salutation, clear body paragraphs, and a complimentary close still apply, even though the address block is often unnecessary in an email.
Frequently Asked Questions
What is the standard format for a business letter?
Most business letters follow full block format, with the date, addresses, salutation, body paragraphs, closing, and signature all aligned to the left margin. Paragraphs are separated by a blank line rather than an indent, which keeps the letter easy to scan on screen or in print.
What font and font size should I use for a business letter?
A standard, easy-to-read font such as Times New Roman, Arial, or Calibri, sized between 10 and 12 points, works well for most business correspondence. Avoid decorative or handwriting-style fonts, which can look unprofessional in a formal setting.
How do you address a business letter when you don’t know the recipient’s name?
When you cannot identify a specific person, “Dear Hiring Manager,” “Dear Customer Service Team,” or “To Whom It May Concern” all work as fallback salutations. If you can identify the department or role but not the individual’s name, addressing that group directly, such as “Dear Human Resources Department,” tends to feel more personal than a generic greeting.
What is the difference between block format and modified block format?
In full block format, every part of the letter, including the date and signature, aligns to the left margin. In modified block format, the body paragraphs stay left-aligned, but the date, closing, and signature shift toward the center of the page. Both are acceptable in professional settings, though full block format is more common today.
How long should a business letter be?
Most business letters fit on a single page. If your content runs longer, consider whether some details belong in an attachment instead of the letter body, so the main message stays easy to read at a glance.
What’s the difference between “Enclosure” and “Attachment” notations?
“Enclosure” or “Enc.” traditionally refers to physical documents included with a printed, mailed letter. “Attachment” is generally used for files sent along with an emailed or digital letter. Either term is understood in most professional contexts, so consistency within the letter matters more than which term you choose.
Is it appropriate to send a business letter as an email instead of printing it?
Yes, in most everyday business situations. Formal notices, contracts, and letters intended for a permanent file often still call for a printed or PDF version, while routine correspondence is commonly sent by email with the same tone and structure as a printed letter.
How do you sign a business letter that is sent electronically?
A scanned signature image, a typed name, or a digital signature tool all work for electronic letters. The recipient generally understands that a wet-ink signature is not expected on a digital document, so a typed name below the closing is often sufficient.
Should I use “Sincerely” or “Best regards” to close a business letter?
Both are acceptable in professional correspondence. “Sincerely” tends to read as slightly more formal and works well for first contact or official notices, while “Best regards” or “Kind regards” fit ongoing professional relationships where a warmer tone is appropriate.
