Most e-mail messages will be contained on one screen, though some topics warrant extra space. If the message would go on for many screens, or if you need to incorporate letterhead, charts, or graphics into your message, attach a separate document. The attachment feature, available on most e-mail software, enables you to attach, or add, documents that have been created in separate files. Attachment software expands the capabilities of e-mail, allowing the writer to deliver longer, more comprehensive documents, including word processing, spreadsheets, charts, and graphics.
Before attaching a document, however, consider its appropriateness.
