Knowing how to write an impressive business letter is imperative for maximum career success.

By writing with professionalism, you’re leaving a lasting positive impression and you’re enhancing your chances for strong results.

Here’s how to write a professional business letter:

1. Stationery

Of course, professionals use business letterhead (8 ½ inches by 11 inches).

If you don’t have company or personalized stationary, then you must remember to type your contact information either centered at the top of the page or under your signature.

Top professionals often use their own personalized monarch or executive letterhead (7.25 inches by 10.5 inches).

2. Business-like font and size

Readability is important. So choose a generally accepted business font and size. Typically, Times New Roman or Arial in size 12 is widely accepted.

If you’re writing to a conservative person and business, Times New Roman is best.

3. Plan the components

Plan your letter by writing a list of the details you need to include in your correspondence. This will serve as your checklist so you don’t inadvertently forget something.

Make sure every point is focused — relevant and germane to the topic.

4. Use an economy of words

You’ll increase your odds that your letter will be read and acted upon, if you write succinctly. Avoid unnecessary adjectives and adverbs.

In most cases, a one-page letter is best.

5. Professional wording

Don’t use annoying buzzwords, incorrect idioms, or poor English grammar.

When in doubt for business formality, avoid using contractions.

6. Tone

Without appearing to be servile or gushing, decide whether to compliment the person or company.

Don’t use an arrogant tone; try to be positive. You’ll also convey an unprofessional tone if you write long sentences or write unnecessary sentences.

Avoid using exclamation points. That means no emotional verbiage, especially anger.

Be mindful of your image. When in doubt, try to imagine how your letter would look to readers if your letter were printed in a newspaper article.

7. Addressing the letter

Margin-wise, make sure you send a properly spaced letter.

Depending on the length of the letter, an inch or so under the date on the left, list the recipient’s name.

On the following lines, list the person’s title, company name and then the person’s address.

8. Salutation or greeting

The main thing to remember is to show respect for the person. Below the recipient’s address, double space down to insert a salutation such as “Dear … :” Address the person with formality, “Dear Mr. … “ or “Dear Ms. …”.

If you’ve had a lot of contact with the person and typically refer to the personal by the first name, it’s probably OK to do so in your letter.

9. Block style

For easier reading, it’s preferable to structure the paragraphs aligned to the left with no indentation.

10. Highlight the subject matter

For important letters, it’s best to indicate the subject or purpose. You can abbreviate the word “regarding” with “RE:” above your salutation that contains the person’s name.

Or, you can write the purpose of your letter in the center of the page just above the first paragraph.

“You glance at an e-mail. You give more attention to a real letter.”

11. First paragraph

Indicate why you’re writing the letter.

12. Giving criticism 

If the letter is intended to criticize the recipient, be assertive with specificity, not aggressive.

To show objectivity, offer a compliment for what the person or company is doing well. (For examples, see the recommended techniques in How to Get Great Service from Dysfunctional Vendors.)

13. Avoiding starting paragraphs in first-person

To create a professional first impression, your first sentence in every paragraph should avoid using the pronoun “I”.

You want the recipients to know the letter is all about them and what you want to achieve, not about you.

14. Structure your salient points

After writing the purpose, your next two or three paragraphs should contain your main points. Bullet them if necessary.

If you have more than a few, it’s best to indent and number the paragraphs for easier discussion and referencing.

15. Call to action

Be very clear. Whether you’re trying to sell something or wanting to fix a problem, always include a polite call-to-action as a follow-up on your purpose for writing the letter.

While you’re at it in your call-to-action, follow it by preventing buyer’s remorse such as “You will be very pleased … ”

16. Express gratitude

If it’s a sales or solicitation letter or if it’s otherwise appropriate you can express appreciation, such as “Thank you for your consideration.”

17. Closing

For formal letters, use the words Sincerely, Yours truly or Yours sincerely.

If you are on friendly terms and know the person well, you can use Best regards, Cordially or Yours respectfully.

18. Double-check

Proof read the entire letter. Verify you’re spelling names and words correctly. Check the details, any addresses, telephone numbers or e-mail addresses for accuracy.

19. Before mailing, put the letter aside

Re-read your letter and look to see if it needs editing. Be absolutely certain you’re focused in your writing by using an economy of words, a polite tone and call-to-action.
