What an out of office reply does and how to turn it on

An out of office reply is an automatic message that Gmail sends to anyone who emails you while you are away. When someone sends you a message, they get your reply when ready — they do not have to wait until you return to know you received it. Gmail calls this feature "Vacation responder" and it lives in your Settings.

To turn it on, open Gmail and click the gear icon in the top right corner. Select "See all settings," then click the "Vacation responder" tab near the top. Check the box that says "Vacation responder on," set your first and last day away, write your message, and save. Gmail will send your reply to every incoming email until the end date you choose.

The responder turns off automatically on the date you set. You do not have to remember to disable it when you return.

Key Takeaways

  • Your out of office message goes to every sender once per conversation, so they know you are away without you having to reply manually later.
  • Gmail's vacation responder is found in Settings under the "Vacation responder" tab and requires you to set a start date, end date, and message.
  • The responder sends only one reply per person per conversation, not one per email, so your contacts will not be flooded with multiple copies.
  • You can choose whether to send the reply to everyone or only to people in your contacts, which reduces noise from spam and unknown senders.

Writing a message that tells people what they need to know

Your out of office message should be brief and answer three things: when you will be back, whether you will read emails when you return, and what to do if the matter is urgent. A sentence for each is enough.

Example: "I am out of the office from June 10 to June 20 with limited email access. I will read and respond to your message when I return. For urgent matters, please contact [colleague name] at [email address]."

If you will not be reading email at all, say so. If there is no backup contact, say that too — it is better to be honest than to leave someone wondering whether their urgent request was seen. Keep it under 150 words. Long messages are rarely read.

Choosing who receives your reply

By default, Gmail sends your out of office message to everyone who emails you. You can change this by checking the box "Only send a response to people in my Contacts." This option reduces the number of replies you send, because spam and messages from unknown senders will not trigger your responder.

Use this setting if you receive a lot of unsolicited email or if you want to limit replies to people you actually know. If you work in customer service or receive many inquiries from new contacts, leave this unchecked so that all senders get a response.

What happens to emails while you are away

Your out of office reply does not affect how Gmail handles incoming mail. Emails still arrive in your inbox normally. The responder only sends a message back to the sender — it does not sort, delete, or organize your messages.

If you want emails to be organized while you are away, set up filters or labels before you leave. You can also use Gmail's "Snooze" feature to hide emails and have them reappear when you return, though this works only if you snooze them before you leave.

Sending replies to only one email address

Gmail's vacation responder does not let you send different messages to different people or to exclude specific addresses. If you need to send a custom message to your boss or a key client, you have two options: send them a personal email before you leave, or set up a filter that labels their emails so you can find them easily when you return.

To create a filter, go to Settings, click "Filters and Blocked Addresses," and click "Create a new filter." Enter the sender's email address, then choose an action like "explore label" or "Skip the inbox." This way their messages are organized separately and you can prioritize them when you are back.

Turning off your responder early or changing your dates

If your plans change and you need to return early, go back to Settings, click the "Vacation responder" tab, and uncheck "Vacation responder on." Your message will stop sending when ready. You can also edit the end date without turning it off — just change the date and save.

If you realize you forgot to set up a responder before you left, you can still turn it on from anywhere you can access Gmail, including your phone. The responder will send to all new emails from that moment forward.

Privacy and what your out of office message reveals

Your out of office message tells senders when you are away and when you will return. This information is visible to anyone who emails you, including people who are not in your contacts. If you are concerned about security — for example, if you live alone or travel frequently — consider a vague message like "I am away with limited email access and will respond when I return" instead of specific dates.

Your out of office message is also stored in Gmail's servers and is visible to anyone with access to your account. If you share your Gmail password or use a shared device, anyone with access can see what you wrote. Use a strong, unique password and enable two-factor authentication to limit who can see your messages.

Frequently Asked Questions

Will my out of office reply send to mailing lists or group emails?

Yes, if you are on a mailing list, your reply will send to the list address, not to individual members. This can create noise if the list is large. Consider unchecking "Only send a response to people in my Contacts" if you are on many mailing lists, or manually remove yourself from lists before you leave.

Can I schedule my out of office reply to start on a future date?

No, Gmail's vacation responder turns on when ready when you save it. If you need it to start later, set it up the day before you leave or the morning you depart. You can edit the start date anytime, so you can set it early and adjust if your departure is delayed.

What if someone emails me multiple times while I am away?

Gmail sends your out of office reply only once per conversation thread, not once per email. If the same person sends you five emails in one thread, they will receive your reply only once. If they start a new conversation, they will receive it again.

Does my out of office message show up in my sent folder?

No, automatic replies do not appear in your sent folder. They are logged separately in Gmail's system. You can see a record of when your responder was active by checking the "Vacation responder" tab in Settings.

Can I use HTML or formatting in my out of office message?

Gmail's vacation responder accepts plain text only. You cannot add links, bold text, or images. Keep your message straightforward and readable as plain text.
