Question

Give an example of a clear subject line for an email and an unclear subject line. Then explain why the clear subject line is better.

Answer 1

Clear subject line example:
- Request: Approve Q4 marketing budget by Feb 10

Unclear subject line example:
- Quick question

Why the clear subject line is better:
- Specific action: It tells the recipient exactly what you want (approve) rather than making them open the message to find out.
- Identifies topic: “Q4 marketing budget” immediately signals the content and relevant team.
- Includes a deadline: “by Feb 10” lets the recipient prioritize and know the required response time.
- Improves searchability and filing: clear keywords make the message easier to find later.
- Increases response rate: recipients are more likely to open and act on messages when they know what’s required.

Tip: For best results, include who needs to act (if not obvious), the action, the topic, and a date/time when relevant.
