6 Gmail Automation Ideas for 2026: Filters, Templates and Zaps

Want Gmail to do the boring parts for you? Six automations to set up in 2026, from free filters and auto-reply templates to Zaps that post to Slack.

The most useful Gmail automations are filters that label and archive mail as it arrives, templates that answer one kind of email for you, filters that forward specific messages, scheduled sends and nudges for follow-ups, emails turned into tasks, and alerts that push important mail to Slack or a spreadsheet. The first four are free and built into Gmail. The last two use a connector such as Zapier when they need to reach other apps, though emails into Google Tasks is free too.

An inbox fills up with the same handful of emails over and over: receipts, requests that always get the same answer, threads you meant to chase. Each one takes a minute, and the minutes add up to most of the morning. Below are six automations worth setting up, the exact steps for each, what they cost, and how to fix them when they don't fire.

What can you automate in Gmail without another app?

Gmail on its own can label, archive, star, delete and forward incoming mail with filters, send a saved template as an automatic reply, schedule emails for later, bring snoozed mail back at a set time and flag sent emails that never got an answer. You set it all up in Gmail in a web browser, and none of it costs anything.

Everything in Gmail's own toolbox runs on one idea: a search. Filters, auto-replies and forwarding all start in the search box, so a search that finds exactly the right emails is most of the work. Gmail's search operators page lists the ones worth knowing:

  • from: and to: match a sender or recipient, for example from:billing@example.com.
  • subject: matches words in the subject line.
  • has:attachment and filename:pdf catch emails with files, or a specific file type.
  • list: catches mail from a mailing list, which is cleaner than guessing at sender addresses.
  • OR, a minus sign and quotes combine terms, exclude one, or match an exact phrase: from:amy OR from:david matches either sender.

A search you can't get right in the search box won't work any better as a filter. Run it first and read the results before you build anything on top of it.

1. Sort incoming email into labels automatically

A Gmail filter can apply a label to matching emails as they arrive, and skip the inbox so they never interrupt you. Google's filter help page says filters can send mail to a label, archive, delete, star or forward it. Set one up like this:

  1. In Gmail in a browser, open Show search options from the search box.
  2. Enter the search criteria, then click Search and look over what comes back.
  3. Click Create filter below the search fields.
  4. Choose what should happen, such as applying a label and skipping the inbox.
  5. Click Create filter again to save it.

A faster route when the email is already in front of you: check the box beside it, click More and choose Filter messages like these, then adjust the criteria.

I keep one filter that does more for my mornings than any other: anything matching subject:invoice OR subject:receipt goes to an Invoices label and skips the inbox. I open that label once a week, when I'm in the right frame of mind for money, instead of every time a receipt pings. The label is the important part. Archiving without one is how mail goes missing.

If labels are new to you, the guide to Gmail labels covers creating, applying and nesting them before you point filters at them.

2. Auto-reply to one kind of email with a template

Gmail can send a saved template as an automatic reply to any email that matches a filter. This is different from the out-of-office reply, which goes to almost everyone who writes; a template reply answers only one kind of message, such as a request for a price list or a press inquiry. Google's templates help page says a filter is required for this.

Turn on templates and save one

  1. Open Gmail in a browser, click Settings, then See all settings.
  2. Open the Advanced tab, click Enable next to Templates, and click Save Changes.
  3. Click Compose and write the reply.
  4. In the compose window, click More options, then Templates, Save draft as template and Save as new template.

Send it automatically with a filter

  1. Click Show search options in the search box and enter the criteria, for example subject:"speaking request".
  2. Click Create filter.
  3. Check Send template and pick the template you saved.
  4. Click Create filter again.

I get a steady trickle of speaking and podcast requests, and the first answer is always the same: thanks, here's what I need to know, here's when I'll reply. That's the perfect job for a template. The yes or no still comes from me; the template just stops the sender wondering whether the email landed.

Template: first reply to a speaking request
Subject: Re: your speaking request

Hi,

Thanks for thinking of me. To check whether I can make it, could you send:

- The date, time and time zone
- Whether it's in person or online
- Who the audience is and roughly how many people
- How long you'd like me to speak

I read every request and reply personally within a week.

Best,
Adeola

Templates only work on a computer

Google's help page says templates can be turned on and used only from a computer. The automatic reply still goes out when you're away from your desk, because the filter sends it, but you can't insert a template by hand from the Gmail phone app.

Keep the template honest about what happens next. An automatic reply that promises a quick answer and then goes quiet for two weeks does more harm than no reply at all.

3. Forward specific emails to another address

A Gmail filter with Forward it sends only matching emails to another address, such as receipts to a bookkeeper or shipping notices to a shared household inbox. The forwarding address has to be verified first, and Google's forwarding help page says each filter forwards to one address.

  1. In Settings > See all settings, open Forwarding and POP/IMAP and add the forwarding address.
  2. Open the verification email Gmail sends to that address and click the link.
  3. Back in Gmail, refresh the page. Leave automatic forwarding of all mail turned off, or every new message gets forwarded.
  4. Click Show search options, enter the search criteria and click Create filter.
  5. Check Forward it, pick the verified address and click Create filter.

To send the same emails to two people, make two filters. Forwarding filters only act on new messages, so nothing already in your inbox gets sent.

When I hand receipts to someone else, I forward them and also label them in the same filter. Forwarding alone leaves no trail, and the one receipt that goes astray is always the one that matters at tax time.

Can't see the forwarding option on a work account?

On Google Workspace, an admin can switch off Allow users to automatically forward incoming email. When it's off, the forwarding option disappears from Gmail settings entirely, so ask your IT team rather than hunting for it.

4. Put follow-ups on autopilot

Three built-in Gmail features handle follow-ups without any setup beyond a click: Schedule send writes now and delivers later, Snooze hides an email until a time you choose, and Nudges puts unanswered threads back in front of you. Together they cover most of what people use reminder add-ons for.

Schedule send

Write the email, open the small down arrow beside Send and choose Schedule send. Gmail's scheduling page says it holds a maximum of 100 scheduled messages at once, they go out in the time zone you scheduled them in, and they can arrive a few minutes late. Find them under Scheduled in the left menu; canceling one turns it back into a draft.

On Friday afternoons I write the emails I want people to read on Monday and schedule them for 9 a.m. Nobody gets a weekend ping, and my Monday starts with replies instead of a blank compose window.

Snooze

Hover over an email, click the Snooze icon and pick a day and time. According to Google's snooze page, the email leaves your inbox and comes back to the top at that time; until then it waits under Snoozed, or you can search in:snoozed. Snooze is the honest version of "I'll deal with it later", because later actually arrives.

Nudges

Nudges are suggestions Gmail shows above your inbox for emails to reply to or follow up on. To turn them on, go to Settings > See all settings > General, check Suggest emails to reply to and Suggest emails to follow up on next to Nudges, and click Save Changes. Google's reply help page notes that conversation view has to be on for them to work.

Nudges are a safety net, not a system. Gmail picks which threads to resurface, so for anything with a deadline, snooze the email to the day you'd chase it.

5. Turn emails into tasks

Gmail can turn an email into a Google Tasks item from the side panel, and Zapier can send emails into other task apps automatically. Google's Tasks help page describes the built-in way: open the Tasks panel on the right of Gmail, drag the email into it, and click Date/time to give it a due date.

Dragging is manual, which is fine for a few emails a day. To make it automatic, use a signal you already give Gmail. Zapier's Gmail integration has triggers for New Starred Email and New Labeled Email (Zapier's Gmail page lists them), so starring or labeling an email can create a task in whichever task app the rest of your team uses.

Starring works well for this because it costs one click and means one thing. I only star an email when it needs me to do something, so a Zap on stars turns my inbox into a to-do list without a second step. If you star things for other reasons too, use a dedicated label such as To do instead.

6. Send important emails to Slack or a spreadsheet

Zapier can watch Gmail for emails that match a search and post them to a Slack channel, or add each one as a row in Google Sheets. It suits mail a whole team needs to see, such as a contact form, and records you want in one place, such as orders or applications.

The pieces are a Gmail trigger, New Email Matching Search, and an action: Send Channel Message on Zapier's Slack page, or Create Spreadsheet Row on Zapier's Google Sheets page. The search uses the same operators as Gmail, so test it in Gmail first.

How to set up a Gmail Zap

  1. Start a new Zap and pick Gmail as the trigger app.
  2. Pick New Email Matching Search and connect your Google account.
  3. Paste the search you tested in Gmail, for example to:hello@example.com subject:"new inquiry".
  4. Choose the action app, such as Slack with Send Channel Message, or Google Sheets with Create Spreadsheet Row.
  5. Map the email fields (sender, subject, a snippet of the body) into the message or the columns.
  6. Test the Zap with a recent matching email, then turn it on.

Before you post email into Slack, think about who reads that channel. A forwarded email body can carry phone numbers, prices or a customer's complaint word for word. Posting the sender and subject with a link to the email is usually enough, and it keeps the details in Gmail where access is already controlled.

Zapier's pricing page shows a free plan with 100 tasks a month and two-step Zaps (one trigger, one action). The paid Pro plan costs $19.99 per month on annual billing, or $29.99 month to month, for 750 tasks and multi-step Zaps. A Gmail-to-Slack alert is a two-step Zap, so the free plan covers a low-volume version. For alerts on your phone instead of in Slack, see how to get WhatsApp alerts for Gmail, and for files, saving Gmail attachments to Google Drive.

Which Gmail automation should you set up first?

Start with one filter for the email you see most and act on least. For most inboxes that's receipts, newsletters or automated notifications, and a single filter that labels and archives them clears more noise than anything else on this list.

After that, the order depends on where your time actually goes:

  • You answer the same question every week: a template reply (idea 2).
  • Someone else needs certain emails: a forwarding filter (idea 3), or a Slack Zap if it's a whole team (idea 6).
  • Threads slip through the cracks: Schedule send, Snooze and Nudges (idea 4).
  • Emails are really tasks in disguise: stars or a label that feed a task list (idea 5).

One automation at a time is the pace I trust. Live with each for a week before adding the next, because a filter that's slightly wrong quietly hides mail, and you only find out when someone asks why you never replied.

Why isn't my Gmail filter working?

Most Gmail filters that seem broken have a search that doesn't match the emails you expect, or are acting on mail that arrived before the filter existed. Check these in order:

  1. Run the search on its own. Paste the filter's criteria into the search box. If the emails you expect don't show up, the filter can't catch them either.
  2. Forwarding only affects new mail. Google's filter page says forwarding filters act on new messages only, so older emails won't be forwarded.
  3. Check replies in the thread. A reply to a filtered email is only filtered if it matches the same criteria, so a reply with a changed subject line slips past.
  4. Verify the forwarding address. Forwarding only works once the address is verified, per Google's forwarding page.
  5. Look for the setting on a work account. If the forwarding option is missing altogether, your Workspace admin may have turned it off.
  6. Turn on conversation view for Nudges. Without it, Gmail won't suggest emails to follow up on.

A Zap that stays quiet usually has the same root cause. Paste its search into Gmail; if nothing comes back there, fix the search before touching the action.

A Gmail routine you set up by describing it

A filter can sort an email, but it can't read it. In Merlin, our Mac app, a routine can start when a new email comes from a certain sender, has certain words in the subject or has an attachment, and then read it for you. You describe it in Merlin's chat, such as "when my accountant emails with an attachment, tell me what they need and by when." It starts as a draft you can test, runs on its own once you activate it, and the Free plan includes two saved routines of your own.

Frequently asked questions

Can Gmail automatically reply to certain emails?

Yes. Save the reply as a template (turn templates on under Settings > See all settings > Advanced), then create a filter for those emails and check Send template. Only matching emails get the reply.

Can you automate Gmail for free?

Yes. Filters, template replies, forwarding filters, Schedule send, Snooze and Nudges are all free and built into Gmail. Zapier's free plan adds 100 tasks a month for two-step automations to other apps.

Can I create Gmail filters on my phone?

Google's filter steps are written for the web version of Gmail, so create filters in a browser. Once saved, they apply to mail on every device, including the phone app.

How do I automatically forward only some emails in Gmail?

Add and verify the forwarding address under Settings > Forwarding and POP/IMAP, then create a filter for the emails you want and choose Forward it. Make one filter per forwarding address.

How many emails can I schedule in Gmail?

Gmail holds a maximum of 100 scheduled messages at once. They're sent in the time zone you scheduled them in and can arrive a few minutes after the set time.

Why does my Gmail filter not apply to old emails?

Forwarding filters only act on new messages, so older emails aren't sent. For other filters, run the search to find older matches and apply the label or action to them yourself.
