Frequently Asked Questions

How should you structure a formal letter?

A formal letter typically includes three parts:

  1. Introduction: State the purpose of your letter, explain why you are writing, what you hope to achieve, and provide an overview of the important information you will cover.

  2. Main Text: Provide details about the important information outlined in the introduction. This section can range from one to five paragraphs.

  3. Conclusion: Summarize everything discussed in the letter. Include any relevant call to action or next steps.

How should you address a letter?

To address a letter, follow these steps:

  1. Your Contact Information: Place your name, job title, company, business address, business phone number, and business email address left-aligned at the top.

  2. Date: Skip a line after your contact information and insert the date.

  3. Recipient’s Contact Information: Skip another line and add the recipient’s contact information, including their name, job title, company, and company address.

How should you start a letter?

Begin with a salutation, which is a greeting that cues the reader that the message is about to begin. Most salutations start with “Dear,” followed by the recipient's name, and end with a comma. Use title capitalization for all salutations.

If the recipient's name is unknown, you can use the company name, job title, or department name (e.g., “Dear HR Representative”). As a last resort, use the generic salutation “To Whom It May Concern.” Avoid using “Dear Sir or Madam” as it is outdated and refrain from adding titles like Mr., Ms., or Mx. to avoid misgendering.

How should you end a letter?

Formal letters use a complimentary close or sign-off before ending with a signature. Common closes include “Sincerely,” “With sincere gratitude,” or “Sincerely yours.” Other options are “Best” and “Yours.” Capitalize only the first letter of the complimentary close, and end with a comma.

Below the closing, leave four to six lines blank for your signature (either after printing or via an e-signature application). Below the blank lines, type your full name and title.
