How long should an out-of-office message be?

Three to four sentences. Cover your return date, a backup contact, and what the sender should expect. Anything longer usually goes unread.

Should I list a backup contact in my out of office message?

Only if you have cleared it with that person first. If there is no backup, it is fine to simply say you will reply on your return and give the date.

What is the difference between an internal and external ooo message?

Internal messages can reference Slack, project handoffs, and first names, because your colleagues have context. External messages should stay professional, name a formal backup contact, and avoid internal jargon or personal detail.

Can I set different automatic replies for inside and outside my company?

Yes. Both Gmail and Outlook (Microsoft 365) let you write separate messages for people inside your organization and people outside it. Use the internal and external examples above as your starting points.

How do I avoid a huge inbox pile-up while I am away?

The auto-reply does not stop mail arriving, it only sets expectations. To actually keep the pile-up manageable, use a tool like alfred_ that triages incoming mail, drafts replies for your approval, and briefs you on what needs attention, so you return to a handled inbox.

Out-of-Office Message Examples for Every Situation

Writing a good auto-reply takes two minutes, but staring at a blank field makes it feel like ten. This page gives you ready-to-use out-of-office message examples for every common situation, from a two-week vacation to a sick day to parental leave. Copy one, swap in your dates and a backup contact, and you are done. Below the examples you will also find the part most guides skip: what to do about the hundreds of emails waiting for you when you get back.

Good out of office message examples all share the same shape, so once you understand the pattern you can adapt any of them to your own voice in seconds.

What a good out-of-office message includes

Every effective auto-reply answers three questions the sender is silently asking:

When are you back? Give exact dates, not vague phrases like “for a while.” A specific return date sets a clear expectation and stops people from following up sooner than they need to.
Who do I contact if this is urgent? Name a colleague, a shared inbox, or a support alias, and include their email. If there is no backup, say so plainly.
What should I expect? Tell people whether you will reply on your return, whether you are reading anything, and roughly how long a response might take.

Keep it short. Three or four sentences is plenty. Do not overshare your itinerary, and do not promise a same-day reply you cannot keep.

Common mistakes

A few errors show up again and again in automatic reply examples. Avoid these:

No return date. “I am currently unavailable” tells the sender nothing. Always give a date.
A backup contact who was not asked. Confirm with your colleague before you list them. Nobody enjoys discovering they are covering for you from an auto-reply.
Promising too much. “I will reply within the hour” defeats the purpose of an ooo message. Set an honest expectation.
Leaving it on after you return. Set a calendar reminder to switch it off, or your contacts will keep routing around you.
Oversharing. Your clients do not need your flight numbers or the name of your resort. Keep personal detail out of external replies.
Forgetting the internal version. Colleagues need different information (project handoffs, Slack) than outside contacts. Write both.

The real problem: coming back to hundreds of emails

Here is the truth every out of office message hides. The auto-reply is the easy part. The hard part is the wall of unread mail waiting when you walk back in. A single week away can mean 300 to 800 messages, and the first day back is spent sorting noise from the handful of things that actually needed you.

This is exactly the problem alfred_ was built to solve. alfred_ is an AI executive assistant that triages your inbox for you, so time off does not turn into a triage marathon.

While you are away, alfred_:

Tracks follow-ups so the thread that needs a nudge does not slip through while you are gone.
Sends a proactive brief that tells you what happened and what needs you, so you come back to a handled inbox instead of a blank wall of unread mail.

The out-of-office message manages other people’s expectations. alfred_ manages the actual work, which means your return is about picking up where you left off, not digging out.
