Business letter format: How to organize your letter

Here’s how to organize and what to include in any formal letter. The exact contents will depend on the type of letter you’re writing but generally, every professional and formal document should include the following:

1. Contact information and date

A CV is usually much longer than a resume. Here are some of the standard sections you can expect to include as part of your CV format:

Patricia Smith
Copywriter
23 Blossom St.
Tampa, FL 00112
555-555-5555
patsmith@email.com

August 15, 2024

2. Recipient’s address

Likewise, you should include the recipient’s contact information with the company name. The only difference is that instead of including their personal physical address, you should write the company’s address.

Joe Thompson
Creative Director
Thompson & Jones Agency
44 Lily St.
Tampa, FL 00112
555-555-5555
joethompson@email.com

3. Salutation

Your greeting should be addressed using the recipient’s formal title. Avoid using the term “To Whom It May Concern,” as it can come across as unprofessional. If you couldn’t find the recipient’s name, address the letter to the department.

Dear Mr. Thompson,
Dear Creative Department,
Dear Human Resources,

4. Body of letter

The body of every polished business letter will typically be divided into three sections:

• The opening paragraph is where you introduce yourself and explain why you’re writing.
• The second paragraph (which can sometimes extend to a third paragraph, depending on the type of letter you’re writing) is where you provide specific details. So, for example, if you were writing a cover letter, here’s where you would describe in more detail the resume skills and experience that make you great for the job. Resignation letters would briefly discuss the reason for the resignation, depending on your relationship with your employer.
• Letter format tips on layout, font, margins and more

Here’s what these paragraphs would look like on a simple resignation letter:

Dear Mr. Thompson,

I am writing to formally resign from my position as a copywriter at Thompson & Jones Agency, effective August 31, 2024.

As you know, journalism has always been my passion. I was offered an opportunity that better aligns with my career goals and couldn’t turn it down. I’m submitting my resignation letter now in the hopes that I can be as helpful as possible during the transition process.

My three years of employment at Thompson & Jones Agency have taught me valuable skills and lessons that I will take with me as I continue growing as a professional. I’m grateful for your mentorship, guidance and support.

Thank you again for the opportunity to work with such a great team.

5. Closing salutation and signature

After the closing paragraph comes the signature. Leave a blank line between the closing salutation and your typed name for your handwritten signature. This should be signed using a black or blue ink pen. Some appropriate closing salutations include:

• Sincerely,
• Cordially,
• Kind regards,
• Best,
• All the best,

We suggest going for “Cordially,” if you don’t know the person and a closing salutation like “Sincerely,” or “All the best,” if you have a good professional relationship with the recipient.

Letter format tips for your layout

Every professional document should be formatted in a way that makes it easy to read. Here are some key points to remember:

• Length: Whether it’s a cover letter format or another type of business letter, their length shouldn’t exceed a page. Be straightforward and get your point across concisely.
• Font type and size: Use professional fonts like Times New Roman, Arial or Helvetica. The size must be 12 across the document.
• Block or indent: If you use the block format, all the text in your letter will be left-aligned. When you use an indented format, your contact information, the date, closing salutation and signature will be right-aligned while the rest of the text is left-aligned. Either method is good for your letter format, although block style is easier to put together.
• Spacing: Select a single line spacing for the body of the letter. You can use an additional line after your address, date, the recipient’s address and salutation. Just make sure everything looks good.
• Proofread: We cannot stress enough how important it is to proofread your business letter. Typos and grammatical errors can leave a negative impression on whoever reads your letter, so double-check what you’ve written to ensure it’s written correctly.

Letter format tips for your email

Your approach to writing an email letter will be slightly different from writing a printed letter.

• Length: The first thing to keep in mind is that an email letter will be significantly shorter. Email correspondence, while convenient and more common nowadays, is still quite informal compared to a printed letter.
• Subject line: The subject line of your email should include the reason why you’re writing.
• Body text: Everything should be summarized in one or two paragraphs.
• Contact information: Your contact information will be written at the bottom, under your typed signature. You don’t have to include the recipient’s contact details.
• Block style: Keep the text left-aligned at all times.

Using the same example from before, here’s how Patricia Smith’s email to Mr. Thompson would look like:

Subject: Patricia Smith – Resignation

Dear Mr. Thompson,

I am writing to formally resign from my position as a copywriter at Thompson & Jones Agency, effective August 31, 2024. I was offered an opportunity that better aligns with my career goals and I am submitting my resignation letter now in the hopes that I can be as helpful as possible during the transition process.

I’m grateful for your mentorship, guidance and valuable lessons.

Thank you again for the opportunity to work with such a great team.

All the best,
Patricia Smith
patsmith@email.com
555-555-5555

Make sure to proofread your email letter before pressing send.
