E-mail and memos are important tools for internal communication within organizations. They are used to inform employees, request data, give responses, confirm decisions, and provide directions. Effective e-mails and memos follow a structure including a subject line, opening, body, and closing. When writing e-mails and memos, writers should be concise, careful of tone and correctness, and avoid sending anything they wouldn't want published. E-mails and memos should be written following a 3-step writing process of analysis, organization, and revision.
