A strong subject line is specific enough to distinguish the message from routine inbox traffic, concise enough to scan on mobile, and aligned with the actual content rather than using manufactured urgency.

- 2Replace every bracketed field with specific information.
- 3Delete any sentence that does not belong in your situation.
- 4Read the result aloud for unnatural transitions or repeated phrasing.
- 5Verify names, dates, links, facts, and promises before sending or publishing.
