The resignation email has replaced the paper letter almost everywhere — but it inherits the same rule: the email confirms a conversation, it doesn't replace one. Resigning cold by email when a call was possible is the single most-remembered mistake in how people leave.
In short: schedule a call with your manager, say it plainly, then send the email the same day to put it in writing. Subject line: "Resignation — [Your Name]". Manager in To, HR in CC only if your company's process says so. The body is the same five sentences as a standard resignation letter: resignation statement, role, last day, thanks, transition offer.
The subject line
Say what it is. This email gets forwarded to HR and filed; cute or vague subjects age badly.
- "Resignation — Maria Alvarez" ← the default
- "Resignation — Maria Alvarez, effective September 26"
- "Notice of resignation — [role]"
Avoid "Quick question", "Update", "It's been a pleasure…" — anything that hides the content.
Template — standard, after the conversation
Subject: Resignation — [Your name]
Hi [Manager],
Following our conversation earlier today, this email is my formal notice of resignation from my role as [job title] at [Company]. My last working day will be [date, two weeks out].
Thank you for the support and the opportunities during my time here. Over the next two weeks I'll document my open work and hand over my responsibilities — let me know what would be most useful.
Best regards, [Your name]
Template — fully remote, no prior call possible
If time zones or circumstances genuinely prevent a live conversation first, acknowledge it:
Subject: Resignation — [Your name]
Hi [Manager],
I'd hoped to tell you this live, but I didn't want to delay the formal notice: I'm resigning from my position as [job title], with my last day on [date]. I'm happy to talk whenever works for you today or tomorrow.
I'm grateful for my time at [Company] and will make sure everything is documented for a clean handover.
Best regards, [Your name]
For the version with no notice period, use the immediate resignation letter templates — same email mechanics, different content rules. For the shortest acceptable body, the short resignation letter versions all work as email bodies.
Who goes in To and CC?
To: your direct manager. CC: HR only if your handbook or process says resignations go to HR — otherwise let your manager forward it. Never BCC anyone. Send it from your work address (it's a company record), and keep a copy: forward it to your personal address or photograph it, along with any reply that confirms your last day — that confirmation matters for final pay and benefits.
When should you hit send?
Early in your manager's workday, ideally right after the conversation — not Friday at 6pm (it stews all weekend) and not minutes before their board meeting. The goal of every timing choice is the same: your manager should never learn about your resignation from someone else, and never feel ambushed by the medium.
FAQ
Is resigning by email unprofessional? Not any more, and for distributed teams it's the norm. What stays unprofessional is skipping the conversation when one was possible.
Do I need a signed paper letter too? Only if HR asks. Most companies treat the email as the formal record.
What if my manager doesn't reply? The resignation is effective when sent, not when acknowledged. If 24 hours pass with silence, forward it to HR with a one-liner: "Sharing for the record — sent to [manager] yesterday."
