The business letter enclosure line is located under the signature section. There are a variety of ways for you to indicate your enclosures. You can simply put the number of enclosures you are including with your letter. This lets the recipient know how many items to look for. In addition to the number of enclosures, you can also be more specific about what you are enclosing. When you do this,
. they know how many to look for and what they are looking for. This helps when something is missing because they will know exactly what to ask for. I get my letter templates from www.microsoft.com.
