The phrase “Resignation Effective [Date]” clearly communicates your intent and timeline at a glance.
Since you are leaving a corporate role, your manager needs to alert payroll, IT, and HR. This subject line informs each team of the start date of the change.
Tone: Warm, appreciative
Most of us love receiving gratitude emails. “Farewell” signals closure, and “[your name]” personalizes the topic.
Use case: You are a long-tenured employee who wants to leave the door open for future collaboration.
Tone: Serious, discreet
Starting with “Private” warns HR not to forward the note. HR teams receive many emails each day, and this phrase cuts through the noise while keeping legal guardrails intact.
Tone: Direct, serious
“Immediate” sits next to “Resignation” to underscore the urgency of the situation. The term “personal reasons” also sets boundaries and reduces gossip, keeping the focus on transition tasks instead of speculation.
Type: Friendly
Tone: Warm, reflective
The line strikes a balance between movement (“Moving On”) and gratitude. It’s a good subject line if you are leaving a startup and want to keep connections lively.
Tone: Candid, gentle
This line shows sincerity. Perfect if you had a good time with your colleagues or the company.
Tone: Upbeat, forward-looking
“Celebrating” sparks curiosity while “Effective [Date]” grounds logistics. Together, they signal that change equals progress, not conflict.
Tone: Optimistic, connective
Many industries cycle talent. This subject line hints at the potential for employees to return, which eases the resentment that sometimes arises during the exit process.
Tone: Orderly, proactive
“Project Handoff” lives right beside “Resignation,” offering immediate benefit.
Tone: Apologetic, concise
“Short Notice” sets expectations for urgency while “Last Working Day” gives a clear endpoint. Pairing both reduces follow-up questions.
Tone: Flexible, factual
“Stepping Down” feels softer than “Quitting.” It encourages conversation about alternative arrangements instead of a quick goodbye.
Use case: You just became a parent and need reduced hours.
