Google Mail Out of Office Reply: How to Set Up and Write Gmail's Vacation Responder

Google Mail is the everyday name a lot of people still use for what Google has branded Gmail since 2004, and the out of office feature sits inside Gmail's settings under the label Vacation responder. It is not a separate app or a hidden menu; it is one toggle in the General tab of Settings that, once turned on, automatically emails anyone who messages you during a date range you choose.

The name confusion has a real history behind it. In the United Kingdom and Germany, Google actually operated the service under the name Google Mail for years after its 2004 launch, because another company already held rights to the Gmail trademark in those markets. Google eventually settled those disputes and consolidated everyone under the Gmail name, but the older branding is part of why so many people still search using the words Google Mail instead of Gmail when looking up this exact setting.

The mechanic is simple but has one detail that trips people up. Gmail's auto-reply does not fire on every single message that lands in your inbox. Once it replies to a specific sender, it will not reply to that same sender again for four days, even if they email you five more times in that window. This keeps the feature from spamming a coworker who messages you repeatedly about the same project while you are away.

The setting also respects your date range precisely. If you set a start date in the future, Gmail waits until that day to activate it and turns it off automatically at the end of your range, unless you leave the end date blank, in which case it keeps running until you switch it off manually.

Setting up an out of office reply in Google Mail on desktop takes about two minutes once you know where the setting lives.

• Open Gmail in a browser and click the gear icon in the top right corner
• Click 'See all settings'
• Stay on the 'General' tab, the first one that opens by default
• Scroll down until you find the 'Vacation responder' section
• Select 'Vacation responder on'
• Enter a first day, and optionally a last day if you know your exact return date
• Add a subject line, something like 'Out of Office Until [date]'
• Write your message in the text box below the subject line
• Scroll to the bottom and click 'Save Changes'

A few desktop-specific details matter here. Gmail shows a banner at the top of your inbox as a reminder that the auto-reply is active, with a direct 'End now' link so you do not have to dig back into settings if you return early. The message box supports basic formatting, including bold, italics, and links, which is useful if you want to bold your return date or link to a colleague's calendar.

The Gmail app on iOS and Android reaches the same setting through a different path, since there is no visible gear icon on mobile.

• Open the Gmail app and tap the three-line menu icon in the top left
• Scroll down and tap 'Settings'
• Tap the specific Google account you want to set the reply for
• Tap 'Vacation responder'
• Toggle it on and fill in the same fields available on desktop: first day, last day, subject, and message
• Tap the checkmark or 'Done' in the top corner to save

One mobile-specific catch: if you manage multiple Gmail accounts on your phone, this setting is per account, not global. Turning on an auto-reply on your work account does nothing for a personal account added to the same app. If you need one on both, repeat the setup inside each account's settings separately.

The wording of your auto-reply matters more than the fact that you turned one on. Gmail does not add any framing text of its own. Whatever you type into the message box is exactly what the sender receives, with no disclaimer or extra formatting layered on top, so the words carry the entire impression.

For a short trip of a few days, keep it brief:

Subject: Out of Office, Back [date]

Message: Thanks for your email. I am out of the office until [date] and will respond when I am back. For anything urgent, contact [name] at [email].

For a longer absence such as a two-week vacation or parental leave, add a named alternate contact and be explicit that your access will be limited:

Subject: Out of Office Until [date]

Message: Thank you for reaching out. I am away from [start date] through [end date] with limited access to email. For time-sensitive matters, please contact [name], [role], at [email]. I will respond to your message after I return on [return date].

A subject line habit worth adopting: the subject you type into the message box shows up in the recipient's inbox exactly like a regular email subject, so avoid anything cryptic. 'Vacation Responder' or 'Auto-Reply' by themselves tell the sender nothing about when you will be back; put the date directly in the subject so people can decide whether to wait or escalate.

By default, the feature sends to anyone who emails you, including mailing lists and automated systems, unless you narrow it down. Two checkboxes below the message box control this.

'Only send a response to people in my Contacts' restricts your reply to senders already saved in your Google Contacts. This is the most useful setting for personal Gmail accounts, since it stops the auto-reply from going out to newsletters, receipts, and cold outreach that happen to land in your primary inbox.

If you use a Google Workspace account through your employer, a second checkbox appears: 'Only send a response to people in my organization.' This limits the reply to colleagues on the same company domain, which is useful when you want internal coworkers to know you are away without sending the same message to every external client or vendor who emails your work address.

Neither checkbox lets you build a custom list of specific people or exclude specific domains. If you need finer control, such as sending one message to clients and a different message to your team, the vacation responder cannot split traffic that way; you would need a filter-based workaround or a different email client with rule-based auto-replies.

Turning off the auto-reply works the same way it was turned on, through Settings on desktop or the same menu on mobile.

On desktop, go back to Settings, General tab, scroll to Vacation responder, and select 'Vacation responder off,' then click 'Save Changes' at the bottom. If it is currently active, Gmail also shows a banner at the top of your inbox with an 'End now' link, which is faster than navigating through settings when you return early from a trip.

On mobile, open the same screen used to set it up and toggle the switch off, then save.

Scheduling in advance uses the same first day and last day fields you already filled in. If you set a first day in the future, Gmail holds off activating the reply until that date arrives, so you can prepare it a week ahead without it going live immediately. If you leave the last day blank, it keeps running indefinitely until you switch it off manually, which is easy to forget about after a short trip turns into an extra few days away.

Gmail handles the mechanics of sending your out of office reply, but it has no opinion about whether the words in that message actually sound like you. Writing something specific, appropriately brief, and calibrated to who is reading it still takes a few minutes of thought, which is easy to skip when you are rushing to leave for a trip.

Daily AI Writer's AI Writing Assistant can draft the message for you based on a few details: how long you will be away, whether it is vacation or leave, and who should be contacted in your absence. You get a complete draft in seconds that you can paste directly into the message box.

If you already have a draft you are not happy with, the AI Rewrite Assistant can tighten wording that feels too long or too formal, a common problem with auto-replies written quickly right before someone leaves the office. And if you are the one covering for a colleague and need to reply to messages that hit their auto-reply, the AI Reply Assistant helps you respond quickly instead of starting from a blank screen for every forwarded email.

The app is available on mobile, so you can draft your message the morning you are leaving, copy it, and paste it straight into the Gmail app's vacation responder field before you close your laptop for the trip.
