Just tell me the difference between "enclosed" and "attached" in commercial letters. When should we use enclosed and attached?
enclosed means, inside an evelope, a body of text; e.g., Please find enclosed ...
attached means, separate, joined/added to, outside the envelope, stapled or paperclipped to the main page; e.g., Please find attached ...
With e-mail, use enclosed if the document is inside the body of the e-mail message, and use attached if the document is not inside the body - is added as an <attachment>.
