Even in 2024, with all the emails, Slack messages, and text messages we send every day, the business letter isn’t dead. In fact, because nobody sends them anymore, receiving a perfectly formatted physical letter (or a formal digital PDF) makes you stand out. It shows you mean business.
But if you haven’t written one since high school, the rules can feel a bit fuzzy. Do you put the date at the top or the bottom? How many spaces do you indent? Do you need to include your address if they already know it?
Let’s break down the standard business letter format so you never have to guess again.
1. Your Contact Information (Optional but Recommended)
If you are printing this letter on actual paper, put your name, address, email, and phone number at the very top. If you are sending it as an email attachment or a PDF, you can usually skip this part since your email address is already visible.
2. The Date
Directly below your info (or at the very top if you skipped step one), put the date. Use the standard American format: Month Day, Year (e.g., October 24, 2024). Don’t use numbers like 10/24/24, as it can be confusing to international readers.
3. The Recipient’s Information
Leave a blank line, then add the recipient’s name, title, company, and address. This is called the “inside address.” Even if you are emailing the letter, include this. It looks highly professional and shows you took the time to format it properly.
4. The Salutation
Leave another blank line. Always use “Dear [Title] [Last Name],” followed by a colon. Dear Mr. Smith: or Dear Dr. Jones:.
Avoid “To whom it may concern” if at all possible—it feels incredibly cold and lazy. Take two minutes to call the company and find out exactly who will be reading the letter.
5. The Body Paragraphs
This is where things get intimidating for a lot of people, but it’s actually simple if you stick to the 3-paragraph rule:
- Paragraph 1 (The Reason): State exactly why you are writing. Don’t beat around the bush. “I am writing to propose a partnership…” or “I am writing to follow up on our meeting…”
- Paragraph 2 (The Details): Provide the supporting information, numbers, or background story they need to understand your point.
- Paragraph 3 (The Action): Tell them what happens next. “I will call your office next Tuesday to schedule a meeting” or “Please find the attached contract for your review.”
A quick note on spacing: For traditional block format (the most common), do not indent your paragraphs. Just put a blank line between each one.
6. The Sign-off
Leave a blank line after your last paragraph. Use a formal closing like “Sincerely,” followed by a comma. Leave about three or four blank lines for your actual signature (if printing), and then type your full name. Under your name, you can put your title if applicable.
