Under your name at the end of the letter, skip two lines. On the third line, write "Enclosure:" or "Enclosures:" if there are multiple documents. Skip a line after "Enclosures:" and then begin your list of enclosures. Put each enclosed document title on its own line.
If something is enclosed with a letter, the notation “Enclosure” is typed a double-space below the writer's initials and/or typist's initials. If more than one item is enclosed, the word is made plural and followed by the number of items (e.g., “Enclosures 2”).
On a paper business letter, you often include the CC line underneath your signature, either above or below any enclosures line.
An enclosure in a cover letter is a list of any additional documents you've included in your application. Typical enclosure documents include letters of recommendation, certificates, a portfolio, work samples, or written tests associated with the job application.
