Both a business or a personal letter can include enclosures. It's always good to let the person receiving the letter know what has been enclosed with it; however, only formal business letters require that you add this piece to the letter. For example, you might be sending in your cover letter to be considered for a job. In this case, you would be letting the potential employer know that you have one enclosure with the letter: your resume. It is a courtesy to the person you're writing to.
Fill in your contact information at the top of the letter, such as your name, address and phone number. Below that, write the date. Below the date, write the salutation for the letter.
Write the body of the letter. In the body, you should explain who you are , if necessary, and why you're writing the letter in the first paragraph. Subsequent paragraphs include other details that you want to provide the recipient with.
Mention the item you have enclosed in the last paragraph of the letter. For example, when submitting a resume, your cover letter might say something like, "As requested, I have enclosed by professional resume that gives more details about my experience."
Close the letter. This involves writing a closing, such as "Kind Regards," and your name.
Write the word "Enclosure" below your name. If there are more than one enclosure, write "Enclosures" and then include the number of enclosures in parentheses. For example, if you are sending a cover letter and including your resume and reference sheet, the end of your letter would say "Enclosures (2)."
