Your out-of-office reply is the first (and often only) email you send while you're away. It sets expectations for every stranger, client, and colleague who writes to you between now and when you return. Most people either overshare, undershare, or trigger the delegate they name into a week of forwarded chaos. This post has twelve examples you can copy — vacation, sabbatical, parental leave, conference, medical, and end-of-year — plus the four traps that make even a well-worded OOO waste replies you actually care about.
The anatomy of an OOO that works is short: reason, return date, delegate contact if genuinely useful, and one sign-off. Under six lines. Here is the setup path for the three clients you're almost certainly using.
Open Gmail → Settings gear → See all settings → General tab → scroll to Vacation responder. Turn it on, set the first day and (optionally) the last day, write a subject and message. Tick "Only send a response to people in my Contacts" only if you truly want to filter — most people leave it off so strangers get the auto-reply too. Save.
New Outlook / Outlook on the web: Settings gear → Mail → Automatic replies. Classic Outlook (Windows): File → Automatic Replies. Toggle on. Set the time range (Outlook will auto-disable at the end date, so you don't have to remember). Write two versions: one for people inside your organization, one for people outside. That two-message split is Outlook's biggest advantage over Gmail — use it.
Apple Mail doesn't have server-side auto-replies. You need to set your OOO on the mail server: iCloud Mail via iCloud.com → Mail settings → Automatic reply; Gmail via the Gmail web setting above; Outlook.com via the Outlook.com web setting. Setting a rule inside Apple Mail only fires while the app is open, which means your Mac needs to stay awake for the entire trip. Nobody wants that.
The iOS Mail app has no server-side OOO either. Set it on the server (via the web) before you leave. If you use Gmail on iPhone, the Gmail iOS app has a vacation responder toggle under Settings → your account → Vacation responder — that flips the same server-side setting the desktop uses.

Subject: Out of office Hi, Thanks for your email. I'm out of office and away from email. For anything urgent, please contact Priya Sharma at priya@example.com. Thanks for your patience, [Your name]
Tip: paste this into your Gmail vacation responder or Outlook automatic replies. Keep it under six lines — the goal is a fast expectation reset, not a mini-essay.
Copy the block that fits, swap in your specifics, and paste it into the message field of your Gmail vacation responder or Outlook automatic replies.
1. Short vacation, single delegate
Hi — I'm out of office through Friday, July 18, and back at my desk on Monday, July 21. For anything urgent, please contact Priya Sharma at priya@example.com. Otherwise I'll reply when I return. Thanks for your patience.
2. Long vacation, no delegate
Thanks for your email. I'm on vacation and offline until Monday, August 4. I'm not checking messages while I'm away and I'm not naming a delegate — please expect a reply the week I return. If your request is truly urgent, resending on August 4 with URGENT in the subject helps it float to the top.
3. Vacation with an emergency escalation path
I'm on vacation through July 20 with limited email access. For anything urgent, please contact my colleague Priya Sharma at priya@example.com. In case of a client-facing emergency only, reach our on-call at oncall@example.com — that inbox is monitored 24/7 and I'll be pulled in if genuinely needed.
4. Extended leave, clear ownership
Thank you for your email. I'm on sabbatical from June 1 through September 15 and I'm fully offline for the duration — I won't see this message. Priya Sharma (priya@example.com) is covering my accounts. She has full authority to make decisions on my behalf and will loop me in only if you specifically ask her to. See you in September.
5. Sabbatical, no delegate at all
I'm on sabbatical through September 15. This inbox is not being monitored. For questions about active projects, please contact our operations team at ops@example.com. Anything time-sensitive will need to wait — my apologies, and thanks for the patience.
6. Parental leave, first-name delegate
Hi — I'm on parental leave and not checking email. I'll be back on October 6. For anything work-related, please contact Priya (priya@example.com), who is covering my responsibilities in full. She has the same context I do on active projects and will make decisions without needing to check with me.
7. Parental leave, generic team routing
I'm out on parental leave through October 6 and I'm fully offline. The best routing while I'm away: for client questions, ping the pod inbox at pod@example.com; for internal requests, our team lead Priya (priya@example.com); for anything HR-related, reach out to hr@example.com. Thanks for your patience.
8. Conference, replies happening in batches
I'm at a conference through Thursday and I'll be checking email once a day in the evenings. Expect a reply within 24 hours. If it's a hard blocker, please tag URGENT in the subject and I'll surface it during the first break.
9. Off-site with limited signal
I'm at a company off-site through Thursday. Wi-Fi is unreliable so I'll be slow to reply. For anything urgent, please contact Priya Sharma at priya@example.com. Otherwise I'll work through the queue when I'm back at my desk on Friday.
10. Short medical leave
Thank you for your email. I'm on medical leave through July 18 and away from email. My colleague Priya Sharma (priya@example.com) is covering urgent items. I'll follow up when I return.
11. Open-ended medical leave
I'm on medical leave and my return date is not yet set. Priya Sharma (priya@example.com) is covering my responsibilities and will confirm timelines with you directly. Thank you for your patience.
12. Holiday closure with a firm reopen date
Our office is closed from December 23 through January 2 and reopens Monday, January 5. This inbox is not monitored during the closure. For urgent client escalations only, please contact oncall@example.com. Wishing you a restful break — talk soon in the new year.
Copying the right template is half the job. These four traps are what make replies pile up anyway.
The single biggest OOO failure mode. You leave for a week naming Priya as your urgent contact. Priya returns from her own trip to 63 forwarded messages, half of which weren't hers to answer. Before you enable the OOO, ping the delegate in Slack or in person, confirm the date range, and agree on what counts as "urgent." A one-line reply from Priya saying "yes, use me" is your permission slip.
The classic version: a company-wide DL gets a message, dozens of people are on vacation, their OOOs all reply to the DL, those OOOs trigger other OOOs, and the storm eats the mail server. Every mail platform since the 1997 Microsoft "Bedlam DL3" incident now suppresses auto-replies to the same sender within a short window, but you can still cause pain if your OOO replies to every incoming message including newsletters. Filters exist for a reason — Gmail's vacation responder skips senders not in your contacts if you tick that box; Outlook's automatic replies has separate inside/outside org rules for this exact reason.
"Back Monday" reads differently in Sydney than in San Francisco. If your work spans timezones, write the return date, not the day of the week: "back Monday, July 21" not "back next Monday." If you're coming back mid-day in your zone but overnight in theirs, add the hour: "back Monday 9am IST." One extra word saves a follow-up email.
Your OOO fires to every sender — cold outreach, spam, your therapist, and the recruiter your CEO forwarded you to. "I'm on paternity leave" is fine; "I'm on paternity leave — my wife had an emergency C-section last night" is not. Vacation locations attract package thieves. Delegation to "my personal assistant" reveals org structure. Keep it factual. Keep it short. Nothing you'd be uncomfortable seeing on LinkedIn tomorrow.
One message, one date range, optional filter to contacts-only. Automatic date-based on/off. No inside/outside distinction. Path: Settings → General → Vacation responder.
Two messages (inside vs outside org), one date range, automatic on/off. The inside/outside split is genuinely useful — internal replies can reference project names, external replies can stay generic. Path: Settings → Mail → Automatic replies.
No server-side OOO. You must set the auto-reply on your mail provider's web interface (iCloud.com, gmail.com, outlook.com) or your Mac has to stay awake. Setting a rule inside Apple Mail is a trap for anyone who's ever slept on a plane.
No. Your signature is what appears at the bottom of every email you send while you're actively working. Your out-of-office is the auto-reply that fires when you're not. They serve different purposes and mixing them is confusing — a signature that says "on vacation until July 18" left behind after you return will make you look like you're perpetually away.
If you check email daily, either write example #8 (batched replies, once-a-day cadence) with no delegate, or don't set an OOO at all and just be slower to respond. Naming a delegate you don't need creates work for them and confuses senders about who owns what.
Yes, but sparingly. A single line at the end pointing to a webinar recording, a new product page, or a case study is fine. Anything longer than one line reads like your OOO is doing double duty as a marketing email — that hurts trust with anyone who was writing about something important.
In Outlook and in Gmail's vacation responder (with the "last day" field set), the auto-reply disables itself on your return date. If you didn't set an end date, it keeps firing forever — Gmail will show a persistent yellow banner at the top of your inbox once you're back, which is your visual reminder to turn it off. Outlook doesn't warn you as loudly, which is why the end-date field matters.
No. If someone's OOO says they're not checking, treat it as read-only. If you need an answer before their return date, contact the delegate they named (that's the whole point of the delegate) or your own team lead. Sending "no worries, enjoy!" back to their OOO fires a second auto-reply from them and clutters two inboxes for zero information.
The best out-of-office reply resets the sender's expectations in one glance: reason, return date, escalation path, sign-off. Every extra line is a place your delegate ends up doing more work than they signed up for. Copy the block above that fits, delete anything not directly useful, and enable it.
