When to Send Your Farewell Email at Work: Timing That Lands

The best time to send a farewell email at work is mid-morning, two to three days before your last day, on a day that leaves at least one full workday between the send and your departure. That window gives colleagues time to reply, stop by, or schedule a proper goodbye before your inbox goes dark.

Most people either send it too early (nobody remembers) or too late (their replies land in a mailbox nobody reads). Both mistakes are avoidable once you pick a specific hour and a specific day, instead of "sometime that week."

Here's how to think about the timing, and how to pick the exact slot that fits your situation.

The short answer, by exit type

If you have a normal two-week notice and a Friday last day, send the email Wednesday morning around 10 a.m. That gives Wednesday, Thursday, and Friday morning for people to respond, and it keeps your Thursday and Friday free for the actual in-person goodbyes.

If your last day is a Thursday, send Tuesday around 10 a.m. If your last day is a Monday (rare, but it happens), send the previous Thursday, not Friday afternoon, so the message doesn't get buried in weekend inbox debris.

If you've only given a few days notice and your last day is tomorrow, send first thing tomorrow morning - 8:30 or 9 a.m. - so replies land before you lose inbox access.

What actually works

Two constraints matter more than any hour-of-day trick.

Constraint one: your inbox is about to disappear. On your last day, most companies revoke email access at end of business, some at noon, a few the moment you badge out. Anything sent after that window arrives to a black hole. If you want to hear back from people, the email needs to go out early enough that responses can arrive while you still have access.

Constraint two: people need a reason to open it now, not later. A goodbye email sent five days out gets skimmed and shelved. By your last day, it's forgotten. A goodbye email sent 48 to 72 hours out is fresh enough that people act on it - write back, forward it to a shared channel, put a coffee on the calendar.

The mid-week, mid-morning window threads both constraints.

Day of the week matters more than the hour

Tuesday, Wednesday, and Thursday are the strongest days to send. Monday inboxes are drowning in weekend catch-up; your email disappears into the pile. Friday afternoon is worse - half the office is mentally checked out, and any reply that comes in on Monday hits your closed account.

If you can pick, aim for a mid-week send. If your last day is fixed to a Friday, that means Wednesday is your window, not Thursday and not Friday morning.

The 10 a.m. rule

Between 9:30 and 10:30 a.m. in the recipient's time zone is the sweet spot. People have cleared the overnight backlog, they aren't in back-to-back meetings yet, and they still have runway to reply before lunch. Send before 8 a.m. and it gets buried under everything that lands next. Send after 3 p.m. and it competes with end-of-day scramble.

If your team is spread across time zones, pick the time zone where the majority of the people you actually want a reply from live, and set a scheduled send for their 10 a.m. Every modern email client supports it.

The exceptions

If you've been laid off

Timing compresses. You may only have hours of email access left. Send the email the same day you get the news, in the first free half-hour you have, and keep it short. Getting the message out matters more than picking the perfect slot. (Our guide on what to write in a goodbye email after a layoff covers the tone rules for this case.)

If you're a remote employee

You don't have the option of "stopping by their desk," and neither do they. Push the send earlier - three to four days out - so remote colleagues have time to book a farewell call rather than just a two-line reply. Also include a personal channel: a LinkedIn handle, a personal email address, a Signal number. Without a hallway to bump into each other in, the email is the entire bridge.

If your role involves external clients or vendors

Send that email separately, and send it earlier - five to seven business days before your last day. External contacts need runway to be introduced to your replacement, to close open loops, and to update their records. Bundling clients into the same team goodbye is a common mistake. Separate emails, separate timing.

If nobody knows you're leaving yet

Do not send the farewell email until your manager and immediate team have been told, in that order. Announce upward, then across, then broadly. Sending a mass goodbye before your manager has looped in leadership is the fastest way to burn a reference.

What most people get wrong

The failure mode is not usually the hour - it's the recipient list.

People sit down two days before their last day, open a blank compose window, and blast to the "all-team" distribution list, or a Slack #general channel with 400 people. Most of them barely know you. Meanwhile, the six colleagues who actually shaped your years there - the person who covered for you when your kid was sick, the manager two levels up who quietly advocated for your promotion, the peer on another team who mentored you through your first launch - get the exact same generic email as everyone else, or they get missed entirely because they don't sit on the distribution list you defaulted to.

Perfect timing sent to the wrong list is still forgettable.

The calendar you've been living inside for two, five, ten years already knows the answer. The recurring one-on-ones, the standing 3 p.m. Thursday, the launch war-rooms - that pattern is the shape of who mattered. It Was Great Working With You reads it and hands you the actual list, sorted by who you spent real time with, so the email you send Wednesday morning lands with the right forty people instead of the generic four hundred.

A concrete pre-send checklist

Once you have the list and the slot picked, run through this in the hour before you send.

• Draft the night before. Never write a farewell email in the same hour you send it. Sleep on the phrasing.
• Include a personal contact. A LinkedIn URL and a personal email. Not a phone number unless you actually want texts.
• Use BCC on any list larger than 25. Nobody wants their entire team's replies threaded into one runaway chain.
• Keep the subject line specific. "Goodbye" is skimmed. "Signing off Friday - stay in touch" gets opened. (See our list of farewell email subject lines that actually get opened for more.)
• Send from your work address, not personal. Your colleagues need to see it come from the account they recognize.
• Test the scheduled send. If you're using a scheduled send for 10 a.m., double-check the time zone. A miss by one time zone is a common quiet mistake.

What to do after you hit send

Stay reachable. Don't schedule dense back-to-back meetings for the two hours after the email goes out - that's when the replies land, and a quick 45-second Slack DM back to someone who took the time to write feels a hundred times warmer than radio silence.

If someone replies suggesting a coffee or a walk, say yes if you can. The people who write back within an hour are the people who most want to stay in touch. That signal is worth acting on. Our guide on what to do the morning of your last day at work covers the rest of the tempo for that final morning.

The one-line version

Send Wednesday morning, 10 a.m., to a real list, from your work account, with a personal contact included, having drafted it the night before. Almost every farewell-email regret traces back to breaking one of those six.

Pick the slot. Pick the people. Then hit send with your inbox still open long enough to hear back. When you're ready to build the list, start here.
