A useful email explains why it arrived, what must happen, and by when. It is a coordination tool and a record.

Use a subject with topic and action, an opening purpose, essential information, a visible request, and a close. For example, “Confirm support coverage — 18 September launch”. Irene asks Mara and Daniel to confirm the on-call person and escalation route by Wednesday, attaching only the relevant forecast.

Distinguish people who must decide or act from those who only need information. Explain attachments and record team-wide decisions in the shared location.

• Generic subjects. Include topic and action.
• A hidden request. Give it its own paragraph.
• Unexplained attachments. Say what readers should do with them.

1. Write an email confirming tasks before a meeting.
2. Decide who belongs in To and CC.

1. Include purpose, tasks, deadline, and response method.
2. Put responders in To; people who only need the outcome in CC or the later summary.

Effective email makes it easy to decide, respond, and retrieve an agreement. Reports extend that traceability.
