How to set up a vacation responder in Gmail

What is the Gmail vacation responder, and why use it?

The Gmail vacation responder is the built-in feature that sends an automatic reply on your behalf while you are away from your inbox. You write a short message once, set the dates you will be gone, and from then on anyone who emails you gets an instant note back explaining that you are out, when you will return, and what they should do if their request cannot wait. Google sometimes calls it the vacation responder, sometimes the out of office auto-reply on mobile, but it is the same tool: a way to keep your contacts informed without you lifting a finger.

It is a small setting that does an outsized amount of work. A clear automatic reply in Gmail protects your time off, because people stop chasing a response once they know you genuinely will not see their message until next week. It protects your reputation, because a client who gets a polished, helpful reply assumes you are organized rather than ignoring them. And it protects the work itself, because a good out of office message in Gmail can route urgent matters to a colleague who can actually act on them, instead of leaving everything to pile up until you are back.

The opposite is just as true. When you disappear for a week with no auto-reply, you are not leaving one email unanswered, you are quietly breaking an unspoken promise dozens of times over. A client wonders why their proposal went silent. A teammate stalls because they did not know who to ask. A recruiter moves on to the next candidate. None of those people know you are on a beach or in a hospital bed or simply heads-down at a conference. From where they sit, you just vanished. The vacation responder is the one thing standing between your absence and their confusion.

The feature has a few moving parts that trip people up, which is why this guide exists. The Gmail vacation responder is not a fire-and-forget toggle: it has a start date and an optional end date, a separate subject and body, an option to limit replies to people in your contacts, and, on Google Workspace accounts, an extra option to limit replies to people inside your organization. It also has a quietly important behavior most people never notice, which is that it sends only once per sender every four days rather than replying to every single message. Understanding that one rule explains most of the confusion about whether the responder is working at all.

This walkthrough covers the whole thing in order. You will set up the vacation responder on desktop step by step, then dig into each option, including the date range, the contacts-only setting, and the organization-only setting on Workspace. You will learn exactly how often Gmail sends the reply and why it does not fire on every email. You will set it up on the Gmail app for Android and iPhone, where the controls live in a slightly different place. You will get message templates you can paste in and adapt, with a pointer to our deeper library of out-of-office wording. Then you will learn how to turn the responder off cleanly, how to troubleshoot a responder that is not sending, and finally how an AI email client handles away replies, and keeps acting on your inbox, while you are out across every account at once.

How do you set up a vacation responder in Gmail on desktop?

The desktop web version of Gmail is the most complete place to set up your vacation responder, so start here even if you mostly read email on your phone. The whole flow lives in one settings panel and takes about two minutes once you know where it is. Open Gmail in a browser on a computer, and follow the steps below in order. The single most common reason a responder never fires is skipping the very last step, so do not stop until you have saved.

1. 1

   Open Gmail settings

   In Gmail on the web, click the gear icon in the top-right corner. A quick-settings panel slides out. At the top of it, click "See all settings" to open the full settings page. The quick panel alone does not contain the vacation responder; you need the full settings page to reach it.

2. 2

   Scroll to the Vacation responder section

   The full settings page opens on the "General" tab by default. Scroll all the way down, past the signature options, until you reach the section labeled "Vacation responder." It is near the bottom of the General tab, so keep scrolling if you do not see it at first.

3. 3

   Turn the vacation responder on

   At the top of that section, select "Vacation responder on." The moment you do, the date, subject, and message fields below it become active and editable. Leaving it set to "Vacation responder off" keeps everything greyed out and inactive.

4. 4

   Set the first day and last day

   Enter a "First day" so Gmail knows when to start sending the auto-reply. Then optionally tick "Last day" and pick an end date. If you set a last day, Gmail stops sending automatically at the end of that date. If you leave it blank, the responder keeps running until you turn it off by hand.

5. 5

   Write the subject and message

   Type a "Subject" line, such as "Out of office until Monday," and write your reply in the message box below it. The body supports basic rich-text formatting and links, so you can bold a name or link to a colleague's contact. Keep it short: who is away, when you will reply, and who to contact if it is urgent.

6. 6

   Choose who receives the reply

   Below the message, decide whether to limit the reply. Tick "Only send a response to people in my Contacts" to keep it to people you already know. On a Google Workspace account, you will also see an option to send only to people inside your organization. Leave both unticked to reply to everyone who emails you.

7. 7

   Save changes at the bottom of the page

   Scroll all the way to the bottom of the settings page and click "Save Changes." This is the step everyone forgets. Gmail does not auto-save this page, so if you navigate away without clicking the button, your vacation responder is not stored and will never send.

Once you have saved, Gmail confirms the responder is active. When the feature is turned on, a banner appears across the top of your inbox showing the subject of your vacation reply, with a "End now" link you can click to switch it off at any moment. That banner is the easiest way to tell, at a glance, that the responder is live, which matters because a responder you forgot to turn off is its own kind of embarrassing.

It is worth testing the responder rather than trusting it blindly, but testing it is less straightforward than testing a signature, because of the once-per-sender rule we cover below. The cleanest way is to ask a friend on a completely different email account to send you a message after your start date and tell you whether they got the reply. Sending yourself a test from the same account will not trigger it, and a second test from the same friend within four days will not trigger it again either. If your first real test does not produce a reply, jump to the troubleshooting section near the end of this guide; the cause is almost always a setting, not a malfunction.

What do the vacation responder options actually do?

The vacation responder has a handful of options that look simple but each change its behavior in a way that matters. Getting them right is the difference between a responder that quietly does its job and one that either annoys strangers, leaks your travel dates, or never fires when you expect it to. Here is what each control actually does, in plain terms, so you can set them deliberately rather than guessing.

The two date fields are the backbone. The "First day" tells Gmail when to begin sending the auto-reply, and it will not send a single reply before that date even if the responder is switched on, which is what makes scheduling it ahead of a trip safe. The "Last day" is optional, and this is the field people most often get wrong. If you tick it and choose an end date, Gmail stops the responder at the end of that day automatically, so you do not have to remember to turn it off. If you leave the last day blank, the responder runs indefinitely until you switch it off manually, which is fine for an open-ended absence but dangerous if you forget about it.

One detail about the dates catches people out: the responder starts and stops based on the time zone configured on your Google account, not necessarily the time zone of the place you happen to be. If you set up the responder while traveling, or if your account is set to a region different from where you live, the reply can start or end a few hours earlier or later than you expect. For most absences this difference is invisible, because you are away for whole days rather than racing the clock. But if you are setting the responder to begin or end on the exact day of a flight, it is worth being aware that "end of the last day" means end of that day in the account's time zone, which is the same reason a reply can appear to go out just after you are back when a sender actually emailed you while you were still away.

The "Only send a response to people in my Contacts" checkbox is the option most worth understanding, because it solves a real problem and creates a subtle one. The problem it solves is spam: if you reply to everyone, the responder can fire back at junk mail, cold outreach, and unknown senders, which is noise at best and, at worst, confirms to a spammer that your address is live. Ticking the box restricts the reply to people already saved in your Google Contacts, so strangers and bots get nothing. The subtle trade-off is that legitimate first-time senders, a new client, a recruiter, a vendor you have never emailed, are not in your contacts either, so they will not get the reply and may assume you are simply ignoring them. Whether that trade-off is worth it depends on who emails you.

On a Google Workspace account, you get one extra layer: an option to send the response only to people inside your organization. This is genuinely useful for work, because it lets you give colleagues the full picture, you are out, here is your backup, here is your return date, while outside senders, including clients and partners, get no auto-reply at all and never learn the office is short-staffed. Many people combine this with a second, more guarded message for external contacts. The exact wording of these labels can vary slightly between Workspace configurations, and an administrator can set certain defaults, but the behavior is consistent: organization-only keeps your away status inside the company walls.

How often does the Gmail vacation responder send a reply?

This is the single most misunderstood part of the feature, and the source of nearly every "my vacation responder is not working" complaint. Gmail does not send your auto-reply on every incoming email. It sends the reply to each person only once, and it will not send to that same person again for four days, no matter how many times they email you in between. So if a colleague messages you three times in two days while you are away, they receive your out-of-office reply exactly once, on the first message, and then silence until either four days pass or you return.

This behavior is intentional and, once you understand it, sensible. The point of an auto-reply is to inform someone you are away, and they only need to be told that once. If Gmail fired back a reply to every message, a normal back-and-forth would turn into a flood of identical notes, and any other automated system emailing you, a newsletter, a receipt, a notification, would bounce into an endless loop of replies. The once-per-sender, once-per-four-days rule keeps the responder from becoming a nuisance. The downside is purely cosmetic: when you send yourself a test and no reply arrives, or when you email a friend twice and they only get one reply, it looks broken when it is actually working exactly as designed.

• One reply per sender: each person who emails you gets your auto-reply once, not on every message they send.
• A four-day cooldown: Gmail will not send the same person another auto-reply for four days, even if they email you repeatedly in that window.
• Editing resets the counter: if you change the vacation responder message while it is active, the four-day timer resets, so previous senders receive the updated reply the next time they email you.
• Spam is skipped: messages that land in your spam folder do not trigger the responder at all.
• Mailing lists are skipped: emails sent to a mailing list or group you belong to generally do not trigger an auto-reply, which prevents reply storms on shared lists.

There is one useful lever buried in this behavior. If you edit the vacation responder message while it is switched on and save the change, Gmail treats it as a fresh message and resets the four-day counter for everyone. That means people who already received your old reply will get the new one the next time they email you. This is handy if you realize halfway through your trip that you got a date wrong or named the wrong backup contact: fix the message, save, and the corrected version starts going out again. It is also a reason not to fiddle with the message repeatedly while away, since each edit re-arms the responder for people who had already been told.

Keep this rule in mind when you judge whether the responder is doing its job. The right test is a single email from one outside account after your start date, checked once. If that one reply arrives, the responder works, and the absence of a reply on the second, third, or fourth message to the same address is the four-day rule, not a failure. We come back to this in the troubleshooting section, because mistaking normal behavior for a bug sends a lot of people on a fruitless hunt through their settings.

How do you set up the vacation responder on the Gmail mobile app?

You do not have to be at a computer to set up your out of office in Gmail. The Gmail app on Android and iPhone can turn the same responder on and off, which is a relief when you realize on the way to the airport that you forgot to set it. The good news is that the mobile responder is not a separate setting the way the mobile signature is; it is the same vacation responder tied to your account. Turn it on from your phone and it is on everywhere, desktop included. Turn it off from your laptop and it is off on your phone too. The only real difference between the platforms is where the control lives in the menus, and the slightly different name Gmail uses on iPhone.

Choose your platform below. The fields are the same ones you saw on desktop, a date range, a subject, a message, and the option to limit the reply to your contacts, so the only thing you are really learning here is the path to reach them on a small screen.

Because the mobile responder and the desktop responder are the same underlying setting, you should set it in only one place and leave it there. Unlike signatures, where the phone and the web each keep their own version and can clash, the vacation responder has a single source of truth per account. There is no risk of two responders stacking on one reply. The practical upshot is that the phone is purely a convenience: use it to flip the responder on or off when you are away from your computer, and trust that the change is reflected everywhere.

One mobile-specific tip: the once-per-sender, four-day rule we covered above applies identically no matter where you set the responder. So if you switch it on from your phone and then immediately email yourself from that same account to check, you will not see a reply, exactly as on desktop. Test from a different account, once, and you will see it behave correctly.

What should your Gmail vacation responder message say?

Once the mechanics are sorted, the harder question is what the message should actually say. A good vacation responder answers four questions in the reader's mind, fast: are you actually away, or did my email get lost; when will I hear back; what do I do if this cannot wait; and, optionally, why are you gone if that context helps. You do not need a paragraph for each. The best out-of-office messages handle all four in three or four short sentences, because the person reading it wants the facts and then wants to move on with their day.

Be specific with dates and concrete with the escalation path. "I will be back on Monday, June 22" beats "I will be back next week," which goes stale the moment the week turns over. And "for anything urgent, please contact Priya Shah at priya@example.com" beats a vague "please reach out to my team," which leaves the sender with nowhere to go. If you name a backup contact, confirm with that person first; nobody enjoys discovering they are a stranger's emergency contact by accident. Here are three message templates at different levels of formality that you can paste into the message box and adapt.

Notice what is not in those messages: your full travel itinerary, the hotel you are staying at, the names of everyone you are vacationing with, or a detailed medical explanation. An auto-reply goes to everyone who emails you, including people you do not know and would never choose to tell, so keep the personal detail out of the version that can reach strangers. This is exactly where the contacts-only and organization-only options earn their keep: you can write a warmer, more detailed message for people who get it, knowing outsiders are filtered out.

If you want more wording to work from, including separate internal and external versions, and templates for sick leave, parental leave, holidays, conferences, and your last day before leaving a company, we have a full library of out-of-office message examples and templates in our companion guide on how to write an out-of-office message. It covers the tone and length guidance, the mistakes that quietly make you look unprofessional, and more than twenty copy-paste messages grouped by situation, so you never have to write one from a blank page.

How do you turn off the vacation responder in Gmail?

Turning the vacation responder off is as important as turning it on, and a responder you forgot to disable, still telling people you are away a week after you got back, is its own small embarrassment. There are two ways to switch it off, and the fastest one is right in front of you the moment you open Gmail while the responder is active. Both work the same regardless of where you originally set it, because the responder is a single account-level setting.

1. 1

   Use the inbox banner (fastest on desktop)

   When the vacation responder is on, Gmail shows a yellow banner across the top of your inbox displaying the subject of your auto-reply. At the right end of that banner is an "End now" link. Click it and the responder switches off immediately, with no need to dig into settings.

2. 2

   Turn it off in settings (desktop)

   Alternatively, go to Settings, then See all settings, scroll to the Vacation responder section on the General tab, and select "Vacation responder off." Then scroll to the bottom and click "Save Changes" so the off state is stored.

3. 3

   Turn it off on Android

   Open the Gmail app, tap the menu, then Settings, choose the account, and tap "Vacation responder." Switch the toggle at the top off. Because the setting is account-level, this also turns it off on desktop and every other device.

4. 4

   Turn it off on iPhone or iPad

   Open the Gmail app, tap the menu, then Settings, choose the account, and under "Compose and reply" tap "Out of Office AutoReply." Turn the toggle off and tap "Save" in the top-right corner.

The cleaner long-term habit is to let the responder turn itself off. When you set it up, tick the "Last day" box and pick the date you return. Gmail then stops sending automatically at the end of that day, and you never have to remember to disable it. The only reason to leave the last day blank is a genuinely open-ended absence where you do not know your return date, and even then it is worth setting a date a little past your best guess so the responder cannot run forever if you forget.

If you set a last day and the responder still seems to be replying after your return, give it a moment and check the date and time zone on the account, since the responder stops at the end of the last day in the account's configured time zone, which may differ from where you physically are. And remember the four-day rule cuts both ways: someone who emailed you on your last away day may have triggered a reply that, to you, looks like it went out after you were back. That is the timing of their message, not a stuck responder.

Why is my Gmail vacation responder not sending?

A vacation responder that seems not to send is the most common complaint about the feature, and in the large majority of cases it is working correctly and the test was flawed, or one setting was missed. Work through this checklist in order before assuming anything is broken. The first two causes account for most reports on their own.

• You expected a reply on every email. By design, Gmail sends the auto-reply once per sender and then not again to that person for four days. A second or third email from the same address in that window gets no reply. This is the number-one reason the responder looks broken when it is not.
• You tested by emailing yourself. The responder does not reply to messages you send from the same account. Test from a different email address entirely, and only count the first message from that address.
• You did not click Save Changes. On desktop, the settings page does not auto-save. If you switched the responder on but navigated away without scrolling to the bottom and clicking "Save Changes," it was never stored. Re-open settings, confirm it is on, and save.
• The start date has not arrived. Gmail sends nothing before the "First day" you set, even with the responder switched on. Check that today is on or after your first day, and watch for time-zone differences if you set it for the current day.
• Contacts-only is filtering the sender out. If you ticked "Only send a response to people in my Contacts," anyone not saved in your Google Contacts, including most first-time senders, gets no reply. Untick it to reply to everyone, or test from an address that is in your contacts.
• Organization-only is filtering external senders. On Workspace, if you limited the reply to your organization, people outside your company's domain get nothing. Test from an internal address, or remove that restriction.
• The message went to spam or a mailing list. Gmail does not auto-reply to messages that land in spam, or to mail addressed to a list or group you belong to. Send the test as a normal, direct email to your address.

If you have genuinely ruled all of that out, the responder is on, saved, within its date range, with no contacts or organization restriction, and a clean test from a separate outside account still produces nothing, then a couple of edge cases remain. A Google Workspace administrator can, in some configurations, restrict or override out-of-office replies for the whole organization, so a work account that behaves differently from a personal one may be governed by an admin policy worth asking about. And as always, a stale browser session can misreport state, so reloading Gmail or signing out and back in occasionally clears a display glitch. But these are rare; the everyday answer is the four-day rule or a missed save.

It is worth stepping back and noticing how much there is to get right for what is, at heart, a simple "I am away" message: the correct dates and time zone, the right audience filter, the save step, the four-day behavior, and a test designed not to mislead you. None of it is hard, but it is fiddly, and it only covers one Gmail account. If you live in more than one mailbox, you are about to do all of this again somewhere else.

How does AI Emaily handle away replies, and keep working, while you are out across every account?

Everything above is the manual reality of the Gmail vacation responder: a settings panel here, a mobile toggle there, date fields, audience filters, a four-day rule to keep straight, and a handful of ways it can look broken. It is all doable, but it is a lot of fiddly housekeeping, and it covers exactly one Gmail account. The moment you add a second mailbox, a work address on a custom domain, an Outlook account, another Gmail, you set the whole thing up again in a different place with different quirks, and you are once more the person manually keeping away replies in sync across systems that do not talk to each other. Worse, a vacation responder is a dead end: it tells people you are gone, and then nothing happens to the email itself. Your inbox still piles up, untouched, waiting for you to come back to a wall of unread messages.

AI Emaily is an AI-native email client that connects every mailbox you have, Gmail, Outlook, custom domains, and more, into one place, and it treats being away as something to act on rather than just announce. You set an away reply once and it applies across every connected account, so you are not rebuilding the same out-of-office message in five separate settings panels. But the bigger difference is that the agent keeps working while you are out: it keeps reading what lands, triaging it, and drafting replies in your own voice, so instead of returning to an untouched pile, you return to an inbox that has already been sorted, with replies waiting for a quick approval.

• Away replies across every provider: set your out-of-office message once and AI Emaily applies it to the right accounts automatically, whether the mailbox is on Gmail, Outlook, or your own domain, instead of you configuring each one separately.
• Autopilot keeps triaging while you are out: the agent keeps reading, sorting, and labeling incoming mail across all your accounts, so the work of organizing your inbox does not stop the moment you leave.
• Drafts waiting on your return: rather than just telling senders you are away, AI Emaily drafts replies in your voice to the messages that need one, so you come back to prepared responses instead of a blank slate.
• One inbox, every account: because all your mailboxes live in one client, your away status and your follow-ups are consistent everywhere, with nothing to reconcile by hand between providers.
• You stay in control: in the default workflow nothing sends without your approval, with undo and a clear audit of what the agent did while you were out, so coming back is reviewing decisions, not redoing work.

The shift is from announcing your absence to absorbing it. Gmail's vacation responder is a polite sign on the door; it cannot read the mail behind it. AI Emaily is built around the other ninety-eight percent of email, reading what arrives, drafting replies that sound like you wrote them, and handling the routine work, so a week away does not translate into a week of backlog. The away reply is the easy part, handled quietly in the background across every account at once; the real win is that the triage and drafting keep going, and your first hour back is spent approving good drafts instead of digging out from under hundreds of untouched messages.

If you are tired of setting up the same out-of-office message in a different settings panel for every account, or if you simply do not want your inbox to grind to a halt the moment you step away, AI Emaily is built for exactly that. There is a free plan at $0 to try it on your own inbox, and Pro is $17.99 per month billed annually for the full agentic workflow across all your accounts. You can connect your first mailbox and see your away replies handled, and your inbox kept moving, in one place at app.aiemaily.com/signup.

Putting it all together

Setting up a vacation responder in Gmail comes down to one panel and one habit. Open Settings, then See all settings, scroll to the Vacation responder section near the bottom of the General tab, switch it on, set a first day and ideally a last day, write a short subject and message, decide whether to limit the reply to your contacts or your organization, and, crucially, scroll down and click Save Changes. From then on Gmail sends your reply once per sender every four days, and a banner across your inbox reminds you it is live.

The rest is refinement. Set the last day so the responder turns itself off the day you return. Use the contacts-only option on a spam-prone personal account, and the organization-only option on a Workspace account where you want colleagues informed and outsiders unaware. Set or clear the responder from your phone whenever you are away from a computer, knowing it is the same account-level setting everywhere. Test it once from a separate account, and do not mistake the four-day rule for a malfunction. Keep the message itself short, dated, and free of personal travel detail.

And when you notice you are configuring the same away message in three or four different settings pages across Gmail, Outlook, and a work domain, and that all of them leave your inbox to pile up regardless, that is the signal the manual approach has hit its ceiling. An AI email client like AI Emaily sets one away reply across every provider and, more importantly, keeps triaging and drafting while you are out, so you return to an inbox that has been worked, not just one with a sign on the door. Set it once, step away, and let your email largely run itself.
