The Perfect Out-of-Office Message

An out-of-office message — also called an OOO message or auto-reply — lets colleagues, clients, and contacts know you're unavailable and when to expect a response. A good OOO message sets expectations, prevents frustration, and reflects your personal or company brand.

The best OOO messages include three core elements: the dates you'll be away, when you'll return, and who to contact for urgent matters. Everything else is optional. A professional tone suits most workplaces, but a warm or even funny message can strengthen relationships in the right context.

Brevity wins. Two to four sentences is the sweet spot for most OOO messages — long enough to be informative, short enough to read in seconds. For extended leave (parental leave, sabbatical), a slightly longer message is appropriate to explain coverage arrangements clearly.

This free OOO message generator covers 10 common absence scenarios — from vacation and sick leave to parental leave and sabbaticals — across 6 distinct tones. All templates are instantly copyable and fully editable. No sign-up, no data storage, no AI costs.

Tips for a great auto-reply

  • Match your tone to your audience. A funny out-of-office works great for internal teams and creative industries, but stick to professional for client-facing or regulated environments.
  • Always include a return date if you know it. Vague messages ("I'll be back soon") frustrate senders. Even an approximate date is better than nothing.
  • Designate a backup contact for urgent matters. Especially important for absences longer than 2–3 days.
  • Set it before you leave, not after. Schedule your OOO to activate the night before your first day away.
  • Check your email client's character limit. Some systems (especially mobile mail apps) truncate long OOO messages. Aim for under 500 characters for the safest option.

Frequently Asked Questions

What should I include in my out-of-office message?
At minimum: the dates you're away and when you'll return. Optionally include an emergency contact and a brief reason for your absence. Keep it short — most readers just need to know when you'll be back.
Should my out-of-office message be funny?
It depends on your workplace culture. Funny OOO messages are great for internal teams, startup environments, and creative industries. If you regularly correspond with external clients or work in a conservative industry (finance, law, healthcare), stick to a professional or friendly tone.
How long should an out-of-office message be?
2–4 sentences is ideal for most situations. Longer messages (5–8 sentences) are appropriate for extended leave such as parental leave or sabbaticals where more context is helpful. Avoid going over 500 characters to ensure your message isn't truncated.
Should I set an out-of-office for a single day off?
Yes. A short, minimal OOO for a single day prevents confusion and sets appropriate expectations. Use the "Minimal" or "Personal Day" options in this generator for single-day messages.
