How to write a professional out-of-office message.
Five elements, three tone options, and the mistakes most people make. By the end, you'll have a one-paragraph OOO that's professional, brief, and actually does its job.

A professional out-of-office message has five elements: specific absence dates, realistic reply expectations, an urgent contact, an appropriate tone, and under 100 words. Skip apologies, skip "I'll check email occasionally," and pick a tone (formal/warm/brief) that matches your audience.
Specific dates, not vague phrases. "Out from May 8 until May 21" beats "out for the next two weeks." Vague dates are an invitation for follow-up emails asking when you're back.
Tell readers when they can expect a response. "I'll respond in the order received upon my return" is honest. "I'll respond within 24 hours of returning" is a promise that breaks when you have 800 emails to triage.
Name a specific person with their email — and ideally any context they need to help. "Contact my office" is too vague. "Contact Sarah Lee at sarah@example.com — she has full coverage of my client list" is a real route.
Match the tone to your most-common sender, not the one you wish you used:
Long OOO messages don't get read. Most people skim auto-replies in two seconds looking for the absence dates and the urgent contact. Anything else is filler. Brevity is professional — verbosity reads as anxious.
Putting all five elements together:
That's it. 60 words. Five elements. Works for 95% of professional contexts.
Need a tone other than formal? Use our free generator — it produces formal, warm, playful, brief, and firm variants for any of eight reasons (vacation, conference, parental leave, sabbatical, medical, holiday, business travel, personal time).
"Sorry to be unreachable" is unnecessary. You're allowed to take time off. The reader doesn't need an apology.
"I'll be checking email periodically" sounds responsible but defeats the purpose of an OOO. If you're checking, you're not out. The point is to be out.
"For anything urgent, contact Sarah" overloads Sarah and wastes her time on issues she can't actually help with. If different urgent matters need different responders, route them differently.
Auto-replies aren't the place for clever copy. The reader is looking for absence dates, return date, and urgent contact. Anything else is noise.
Email yourself from a personal account before you go. Make sure the auto-reply actually fires. Make sure the urgent contact's email is correct.
A great message tells people you're out and gives a contact. OutOfOfficePro is a live page that does the routing for you — caller picks the issue, we connect them to the right person automatically. Free for one page; $9.99/mo for unlimited.
Set up your routing page →Settings (gear icon) → See all settings → "General" tab → scroll to "Vacation responder" → On → set dates → paste your message → Save changes at the bottom.
File → Automatic Replies (or Settings → Mail → Automatic replies on web) → On → set date range → paste message → Save.
Apple Mail uses iCloud's vacation responder: iCloud.com → Mail → settings (gear) → Preferences → Vacation → enable, set message, save.
Under 100 words. Most readers skim in 2-3 seconds; anything longer doesn't get read.
Briefly, yes — "vacation," "parental leave," "conference." Don't go into detail (especially for medical leave). The reason calibrates the reader's expectations.
List them by category: "For client emergencies, contact X. For billing, contact Y. For new business, contact Z." Don't lump everything to one person.
Most email systems let you set a separate message for internal vs external senders. Use it. Internal can be brief and casual; external should be more formal.
One or two, max, and only in industries where it's culturally appropriate (tech, marketing, creative). Skip them entirely for legal, finance, healthcare, government.
