What a good OOO looks like
An out-of-office reply does four things: confirms you got the email, says when you're back, offers an alternative for urgent matters, and stays short. What it should NOT do is apologize at length, share personal details, or sound defensive. You're on vacation / in a meeting / at a conference: that's normal and nobody needs your permission.
Recommended structure
- Brief greeting. "Hi, thanks for writing."
- Status and dates. "I'm out of the office until [date]."
- What happens meanwhile. "I'll reply when I return." (Be honest if you won't read email.)
- Alternate contact. "For urgent matters, please reach [name] at [email]."
- Simple close. "Best / Thanks for your patience."
Formal vs. casual
Tone is dictated by your industry and role. In finance, law, corporate B2B: formal, concise, no emojis. In creative agencies, startups, relaxed-culture companies: casual, first person, an emoji is fine. The goal is that your OOO doesn't clash with the rest of your emails.
Bilingual: when and how
If you work with international clients, a bilingual version (English + Spanish) is worth having. The generator builds it automatically. Rule: put your primary work language first, secondary second. Separate with a horizontal line or "---" for readability.
Common mistakes
- "I'll check email occasionally". Then everyone writes anyway. Be honest: "I will not check email until I return."
- Personal details. "I'm at the hospital with my mother." Don't share.
- No alternate contact. For real urgencies, always leave someone.
- Massive message. Over 8 lines and people skip it.
- Forgetting to disable it. You're back Monday and the message is still on for a week — looks unprofessional. Use auto-end dates.
Set it up in Gmail and Outlook

- Outlook 365. Settings → Mail → Automatic replies → enable, time window, message (internal/external if you want to differentiate).
