Gmail Auto Reply: Vacation Responder, Templates, AI (2026)

"Gmail auto reply" means three different things depending on who is asking. Someone going on holiday wants an out of office reply, which Gmail calls the vacation responder. A business that gets the same question every day wants a reply to fire on certain emails. A team behind a support@ or sales@ address wants the reply to actually answer the question, and that is the one thing Gmail cannot do on its own.

This guide covers all three, in that order, and is plain about where each one stops. On Outlook instead? See how to automate emails in Outlook. The first two are free and take a few minutes. The third is where AI email automation comes in, and where InboxPilot, which is us, fits.

Three ways to set up a Gmail auto reply

1. Out of office: the vacation responder, for time away

Gmail has no setting called "out of office". The feature is the vacation responder, and it lives in the general settings, not in the compose window.

On a computer:

1. In Gmail, click Settings (the gear at the top right), then See all settings.
2. Stay on the General tab and scroll down to Vacation responder.
3. Select Vacation responder on.
4. Set the first day and, if you know it, the last day.
5. Write the subject and the message.
6. Optionally tick the box that limits replies to people in your contacts.
7. Click Save Changes at the bottom of the page.

In the Gmail app: on Android, tap Menu, then Settings, choose your account, tap Vacation responder, switch it on, fill in the dates, subject and message, and tap Done. On iPhone or iPad, tap Menu, then Settings, and under Compose and Reply tap Vacation responder. Fill in the same fields and tap Save.

Gmail starts sending at 12:00 AM on the first day and stops at 11:59 PM on the last one. To end it early, go back to the same screen and switch it off. If you need words for the message itself, these automated email response examples include out of office, holiday and after-hours replies you can paste in.

Two details matter. Gmail sends the response to a given person once, and again only if they write to you after four days with the responder still on or after you edit the message, so nobody is buried in replies. And you can limit it to people in your contacts or, on a Google Workspace account, to people in your own organisation, which keeps strangers and automated senders from receiving it. It does not reply to messages Gmail filed as spam or to mail sent to a mailing list you are on. Those rules explain most "my out of office is not working" reports.

Google Calendar has its own Out of office entry, which declines meeting invitations for the dates you block. It does not answer email, so set the vacation responder as well.

What the vacation responder cannot do is run on anything shorter than a whole day, so an after-hours auto reply is not possible this way, and it cannot vary the message by who is asking or what they ask about.

2. A filter that sends a template, for a standing reply

This is the setup most people searching for a Gmail auto reply actually want: a fixed reply to certain emails, every day, whether or not you are at your desk.

First enable templates: Settings, See all settings, Advanced, Templates, Enable, then save. Compose the reply you want to send, open the three-dot menu in the compose window, choose Templates, then Save draft as template. Next, create a filter: click the search options icon in the search bar, set the criteria (a recipient such as support@yourcompany.com, words in the subject, a sender domain), click Create filter, tick Send template and pick the one you saved.

From then on every email matching the filter receives that text. Common uses are an acknowledgement on a support address ("we have your message and reply within one business day"), a standing answer to a recurring request, or a reply that points people to a form.

The limits are the limits of any filter. It matches words, not meaning, so a filter on "refund" fires on "no refund needed, just checking in". It sends the same text to everyone who matches. It cannot look anything up. And it lives inside one Google account, so a team of three ends up with three diverging sets of filters.

3. AI that reads the email and drafts the reply

The third kind of auto reply is a different thing altogether. Instead of matching a keyword and sending fixed text, an AI tool reads the incoming email, works out what it is asking, and writes a reply to that message from your own information: your policies, your website, past replies, and systems such as your order data.

InboxPilot, which is us, does this inside Gmail. Connect the inbox with one click, point it at your documents and tools, and each incoming email is sorted by request type and drafted. By default the draft waits in Gmail for a person to approve and send. Once a category is consistently right, order status questions for instance, you can let that category send on its own and keep review for refunds, complaints and anything legal. That is an auto reply that answers the actual question, with a person still deciding what leaves the inbox. The customer service email page walks through a full before and after.

Most businesses answer email slower than they think

The case for automating is not comfort, it is speed. SuperOffice studied company response times and found that 62% of businesses never respond to customer emails at all, with an average response time of over 12 hours, while nearly half of customers expect a reply within four hours.

That gap is rarely about effort. Teams answer the mail they see when they see it. The problem is that repetitive messages bury the important ones, and every reply that requires a lookup, a search through old threads, or a policy check adds minutes that compound across the day. Automation attacks both ends: sorting decides what you see first, and drafting removes the retype.

Seven automations, from filters to AI drafts

Auto replies are one job. If you want to automate the whole inbox, this is the ladder, in the order worth climbing it. The first two rungs are the free Gmail features above; the rest need a tool that can read.

1. Filter and label incoming mail

Build filters for your highest-volume senders and topics: receipts and notifications skip the inbox and get an archive label, known customers get a "customer" label, anything with "invoice" in the subject gets flagged. Ten minutes of filter setup permanently removes the mail you never needed to see.

2. Save templates for your most repeated replies

Write down the five replies you send most often and save each as a Gmail template, the same templates a filter can send automatically. Even without AI, inserting a saved reply and editing two lines beats composing from scratch. This is also useful groundwork: those five replies are exactly what you will later teach an AI agent to draft.

3. Let AI triage and prioritize

This is where a tool like InboxPilot enters. Instead of keyword rules, the agent reads each incoming message and classifies it by what it actually is: urgent, customer inquiry, vendor question, noise. You describe the categories in plain English, and the smart triage applies labels and priorities so the messages that need a human land on top.

4. Auto-draft replies, with guardrails

Configure how the agent responds per inbox: the tone you want, trigger topics it should handle (pricing, hours, order status), and negative keywords that must always route to a person (complaints, legal, anything angry). When a covered question arrives, a drafted reply is waiting in Gmail for you to review and send. Nothing goes out without you until you decide otherwise.

5. Route and forward with workflow rules

Some mail should not be answered, it should be moved. Email workflows written in plain English can forward invoices to accounting, route sales questions to the right teammate, and file the rest. If your team runs a helpdesk, a Zendesk connection lets complex cases become tickets while routine ones are answered in the inbox.

6. Ground the drafts in your own knowledge

An AI reply is only useful if it is correct. Upload your FAQs, policies, and product docs to the knowledge base, or point it at your website. Drafts then cite your actual refund window and your actual pricing rather than a plausible guess. We cover this step in depth in how to generate emails using your documents.

7. Review, then automate the safe slice

Run in draft mode for a week or two and watch what the agent produces. Where drafts are consistently right, turn on auto-send for that workflow and nothing else. Where they are thin, add a doc or an FAQ pair. The end state is not full autopilot. It is a fast draft on everything and automatic handling of the narrow slice you have verified.

The limits of native Gmail automation

Worth being plain about what the free layer cannot do, because this is where most people stall:

• Filters match text, not meaning. A filter on the word "refund" catches "please refund me" and also "no refund needed, just checking in." It cannot tell an angry escalation from a routine question.
• Templates cannot answer. A saved reply covers the question it was written for. The moment a customer asks a variant, someone has to read, think, and edit.
• Nothing drafts for you. Native Gmail can sort, file, and forward, but every reply still starts with a human composing or pasting.
• No shared logic across a team. Filters and templates live per Google account, so three teammates end up with three diverging systems.

If your repetitive mail is low-volume and truly identical, these limits may never bite. They bite when volume grows or when the questions require answers from your own data.

Where InboxPilot fits

InboxPilot is the understanding layer on top of Gmail: AI email automation for Gmail and Outlook that reads incoming mail, drafts replies grounded in your docs, website, and past email, and escalates when it is unsure. Every draft waits for human approval by default, and auto-send is opt-in per request type. Pricing is by conversations handled, with inbound email unlimited and no per-seat fees, and a 7-day free trial with no card: Starter is $39/month for 300, Growth is $99/month for 1,500 with up to 5 team members, Business is $249/month for 6,000 across 3 inboxes, and Scale is $499/month for 20,000.

To be plain about fit: InboxPilot is built for repetitive operational email, things like quotes, order status, and routine customer service in a business inbox. It is not a chat widget, not a ticket queue, and not a personal productivity coach for an executive inbox. If your Gmail problem is ten personal emails a day, the vacation responder and a template filter will serve you fine.

The AI email assistant for Gmail page shows the drafting in detail. To have each new email posted to a team channel, see how to forward Gmail messages to Slack.
