The business letter format comes in various forms depending on the purpose of the letter and the relationship of the parties involved. The three most common formats are the block format, the indented format, and the semi-block format. Each format has its own unique advantages and disadvantages.

The block format is by far the simplest and most common format. The letter is written in a single column, with all the text aligned to the left margin. This format is often used for business letters between people who are not familiar with each other.

The indented format is slightly more complex but also more professional-looking. The letter is written in two or more columns, with the text aligned to the left margin of the first column and indented a few spaces in the subsequent columns. This format is often used for business letters between people who are familiar with each other.

Parts of Business Letter

The semi-block format is a mix between the block and indented formats. The letter is written in a single column, but the text is aligned to the centre of the page instead of the left margin. This format is typically reserved for formal business correspondence.

The block format is by far the simplest and most common format. As such, it is a good choice in most situations where you need to format a business letter. The following article will provide guidelines on how to write a letter using the block format properly.

Business Letters: The Format

  1. Use an appropriate greeting. If you do not know the name of your addressee, or if they are someone of very high rank (such as "President Smith"), then address them with something along the lines of "To Whom It May Concern." Otherwise, use their first and last name or their title and last name (such as "Dear Mr./Ms. Smith"). This is not to be confused with formal salutations described in the next section.
  2. Start right away by getting straight to your point. This means not wasting time on phrases such as "I hope you are doing well" or "It has been a long time." Those can come after a bit more pleasantries have been exchanged (usually in the next paragraph).
  3. Start the first paragraph with a courteous opener, such as "I am sorry for the delay in getting back to you" or "Thank you for your email." This shows that you are taking the time to respond to them and that you appreciate their message.
  4. The following paragraphs should be a discussion of the main point of the letter. Be clear and concise, and use language that is easy to understand. If possible, try to avoid legalese, as not everyone will be familiar with it. If you need to be formal, make sure that you define any terms or concepts beforehand.
  5. Proofread the letter several times to make sure all spellings and grammar are correct, and check your formatting (particularly if you used a non-default font). Make sure that the letter is free of typos, weird sentence structures, etc. You can also have someone else proofread it for you if possible - this will help ensure that your letter is professional in appearance when it reaches its destination.

How Do I Write Thank You Letters?

All business letters essentially end the same way: with an expression of thanks or some other complimentary remark before closing off properly. Yet, there are two ways actually to close the letter itself; either by using one of several standard closings (which might be appropriate in certain cases) or by writing a more specific thanks letter.

The Business Letter Format Example

The following is an example given by renowned academic writing help educators of a business letter that uses the block format.

formats of business letter

Example 1

To Whom It May Concern,

I am writing to let you know that I am no longer interested in the job position that was advertised online a few weeks ago. Thank you for giving me the opportunity to apply, and I apologize for any inconvenience this may have caused.


John Doe

Standard Closings

There are several standard closings that can be used in business letters, most of which echo sentiments of thanks and appreciation. Here are some examples:

  • Best regards,
  • Yours truly,
  • Cordially,
  • Regards,
  • Thank you,
  • Best,
  • Peaceful thoughts,
  • Yours in gratitude, etc.

More Specific Closings

If you want to write a more specific thanks letter - perhaps in response to a job offer or as a follow-up after an interview - then there are several different things you can do. You can mention what specifically impressed you about the company/position or why you feel that you would be the best candidate for the role. You can also express your gratitude for the opportunity and let the recipient know that you are looking forward to hearing from them soon.

There is no one correct way to write a thanks letter; it really depends on what you want to say. However, make sure that all of your writing is professional and respectful - this includes your closing.


Example 2

John Doe

Thank you for your time in interviewing me earlier today. I enjoyed the opportunity to learn more about this position, and I hope that my qualifications are suitable for the role. While several other applicants were also impressive, I believe that I am the most qualified person for this job out of all of them. Between my experience in customer service and ability to think quickly on my feet, not to mention my great passion for working with people across all age groups - both young and old - I'm confident that I can bring a lot to your company moving forward. Again, thank you very much - I look forward to hearing back from you soon so we can discuss this further! Best regards.

Ms. Judy Jones

Account Manager,

ABC Company Inc.

Example 3

123 Main Street, ABC City, California 12345-6789.

Dear Ms. Judy,

I am writing to inform you that I will no longer require the services of your company's cleaners after this month has passed. During our 6 months of business together I have been satisfied with their work however the weekly fees are far too high for my budget at this time and so I will be finding another cleaning service in the near future to take your place. Please let them know that they can stop coming by my house starting next week on Monday mornings as usual at 10 am sharp. Thank you very much!

Example 4

Dear Mrs Jones,

I hope this letter finds you well. I regret to inform you that I will be terminating my agreement with ABC Company Inc. for cleaning services starting next month. The fees have become too much of a burden on my budget at this time. Thank you for the services rendered thus far, and please let the cleaners know not to come to my house after this month.
