How to Write an Effective Subject Line
The subject line is one of the most critical components of a business letter. It provides a quick summary of your message and helps the recipient prioritize their reading.
Characteristics of a Strong Subject Line
- Clear and concise
- Specific to the purpose
- Professional tone
- No unnecessary words
Examples of Subject Lines
| Purpose | Example |
|---|---|
| Job Application | Subject: Application for Marketing Manager Position |
| Complaint | Subject: Complaint Regarding Order #12345 |

Using vague subject lines like “Important” or “Hello” reduces clarity and may cause your letter to be ignored.
