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.

Quick answer

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.

The five elements every OOO message needs

Step 01

State your absence dates

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.

GoodI'm out of office from May 8 until May 21.
BadI'm out for the next two weeks.
Step 02

Set realistic reply expectations

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.

GoodI'll respond in the order received upon my return.
BadI'll get back to you within 24 hours of returning.
Step 03

Provide an urgent contact

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.

GoodFor urgent matters, please reach out to Sarah Lee at sarah@example.com. She has full coverage of my client list.
BadFor urgent matters, please contact our office.
Step 04

Pick your tone deliberately

Match the tone to your most-common sender, not the one you wish you used:

Step 05

Keep it under 100 words

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.

The complete template

Putting all five elements together:

Standard professional templateHello, Thank you for your email. I am out of office from [start date] until [return date] and will not be checking email during this time. For urgent matters, please contact [name] at [email]. They have full coverage and will be glad to help. I will respond to your message in the order received upon my return. Best regards, [Your name]

That's it. 60 words. Five elements. Works for 95% of professional contexts.

Common mistakes to avoid

Apologizing for being out

"Sorry to be unreachable" is unnecessary. You're allowed to take time off. The reader doesn't need an apology.

Promising to check email

"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.

Routing everything to one person

"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.

Adding too much personality

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.

Forgetting to test it

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.

// One step better than a great OOO message

Make your OOO actually route the urgent thing.

FAQ

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

Under 100 words. Most readers skim in 2-3 seconds; anything longer doesn't get read.

Should I include the reason I'm out?

Briefly, yes — "vacation," "parental leave," "conference." Don't go into detail (especially for medical leave). The reason calibrates the reader's expectations.

What if I have multiple coverage contacts?

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.

Do I need a different OOO for internal vs external?

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.

Can I use emojis in a professional OOO?

One or two, max, and only in industries where it's culturally appropriate (tech, marketing, creative). Skip them entirely for legal, finance, healthcare, government.
