ChatGPT Prompt for an Out-of-Office Message

Use this free prompt to write a clear out-of-office auto-reply — when you're back, who to contact, done. Includes versions for vacation, sick leave, and parental leave.

An out-of-office only needs three things: when you're back, who to contact, and a clear "I'm away." ChatGPT pads it with "thank you for your patience during this time" filler. This one keeps it to the parts that actually help the sender.

The Prompt
You are a professional communication assistant. Write an out-of-office auto-reply.

Type of leave: [vacation / general time off / sick leave / parental leave / conference]
Dates I'm away: [START to END]
When I'll respond: [on return / checking periodically / not at all until back]
Backup contact for urgent matters: [NAME and EMAIL — or "no backup, I'll respond when I return"]
Tone: [warm-professional / brief and neutral]
How much detail to share about why I'm out: [none / just "on leave" / specific]

Rules:
1. Lead with the key facts: that I'm away and when I'll be back.
2. Give the backup contact clearly if I provided one.
3. Keep it to 3-4 sentences. No filler like "thank you for your patience during this time."
4. Match the tone to the leave type — lighter for vacation, simple and private for sick/medical leave.
5. Banned phrases: I will get back to you as soon as humanly possible, your message is important to me, during this time, please bear with me.
6. If it's sick or parental leave, keep the reason vague unless I asked for specific — just point to the backup contact.

How to Use This Prompt

  1. Fill in your dates and backup contact.
  2. Paste into ChatGPT, Claude, or Gemini.
  3. Copy the result into your email client's auto-reply / vacation-responder settings.
  4. Set the start and end dates so it turns off automatically when you're back.

Example Output

Subject: Out of office until June 2

Hi, thanks for your message. I'm out of the office through June 1 and will reply when I'm back on June 2. For anything urgent before then, please reach Dana Cole at dana@company.com. Otherwise I'll get to your note in the order it came in once I return.

Best,
Alex

Tips to Get Better Results

  • Always name a backup if you have one — it's the single most useful line for whoever's emailing you.
  • Set the auto-end date so you don't leave it running after you're back (a stale OOO looks careless).
  • Keep medical/sick leave private. "I'm on leave" plus a backup contact is all anyone needs.
  • Have a short version for internal email and a slightly fuller one for external — ask the prompt for both.
