Clarity and Professionalism
Your subject line should immediately convey the purpose. Use clear phrases like "Last Working Day Notice" or "Final Day at [Company Name]". Avoid vague or emotional language. Keep it professional yet warm, maintaining the same tone you've used in business communications throughout your tenure.
Include Key Information
Incorporate your last working date for quick reference (e.g., "Last Day - [Date]"). If you're the sender, include your name ("John's Last Working Day - July 30"). For team announcements, mention the departing employee's name. This helps recipients prioritize and file the email appropriately.
Consider the Audience
Tailor the subject based on recipients. For HR/management: "Formal Notice: Last Working Day [Date]". For colleagues: "Goodbye & Thank You - Last Day [Date]". For clients: "Transition Notice: My Last Day at [Company]". The right framing ensures appropriate attention from different stakeholder groups.
