Do you need to a write a letter for business, professional, or employment purposes? The content and format of the letter you write will depend on the circumstances. You may need to write a letter or email message to apply for a job or to contact a client. Or perhaps you need to send an appreciation letter, a business announcement, or a resignation or retirement letter.

Read below to see a list of types of letters, as well as examples of each. Also, review a list of elements to include in any business letter or email.

What to Include in a Business Letter or Email

​In some instances, what you include, how you write the correspondence, and the format of the letter will vary. However, a basic professional letter will include the following:

  • Subject line: If you are sending an email, include a clear subject line that concisely explains the purpose of your email. For example, it might read, "Subject: Congratulations on Promotion."
  • Contact information: Include all your contact information — full name, address, phone number, and email address — so it's easy for the person you are contacting to respond to you. In a letter, you will include this information at the top of the page (you will then follow this information with the date, and the contact information of the person to whom you are writing). In an email, you will include this information in your email signature, below your name.
  • Greeting: Include a salutation at the start of your letter. Make sure you use the appropriate name and title for the person.
  • A brief introduction: After your salutation, include a brief introduction. This might include a brief, “I hope you are well,” or some other friendly introductory phrase. Then, dive right into explaining why you are writing.
  • The main purpose of your letter: The main part of your letter will focus on your purpose. When writing the letter, be concise. Two or three paragraphs are plenty. Your letter shouldn't be longer than one page. If it is an email, it should be even shorter. If you have additional information to share with the reader, offer to discuss it during a call or provide an attachment or enclosure with the details.
  • Closing: End your letter with a professional closing that conveys your thanks and respect. Closings like “Sincerely,” “Best,” and “Regards” work well.
  • Signature: If you are mailing a hard copy of the letter, include your handwritten signature above your typed signature. If you are emailing the letter, just include your typed signature.

How to Use Letter Examples

It is a good idea to review letter and email examples before writing your own. Examples allow you to see what kind of content you should include in your letter. They can also help you with the layout and format of your letter.

While examples, templates, and guidelines are a great starting point to your letter, you should always be flexible. Do be sure to take the time to personalize your letter, note, or email message so it reflects the specific reason why you are writing.
