The 9 Best Ways to Automate Gmail and Save 10+ Hours a Week

If you’re looking for ways to automate Gmail, you’re already halfway there: most of what fills up an inbox is repetitive, and repetitive tasks are exactly what automation is good at.

According to research from McKinsey Global Institute, the average knowledge worker spends around 28% of the workweek — roughly 11 hours — on email. And as Cal Newport describes in Deep Work, the constant urge to check email doesn’t just cost that time directly. It reduces our capacity to do meaningful work in between.

This guide covers 9 ways to automate Gmail — from AI-drafted replies and automatic inbox categorization to templates, scheduled sends, filters, and personalized mail merge — so you can spend less time in your inbox and get back 10+ hours a week.

Here’s what we’ll cover:

1. Draft Replies Automatically with AI
2. Sort and Categorize Your Inbox Automatically
3. Create Gmail Templates and Automated Canned Responses
4. Schedule Replies and Auto Follow-Ups
5. Set Up Gmail Filters and Rules
6. Move Emails to a Folder Automatically
7. Hide Promotional Emails from Your Inbox Automatically
8. Forward Emails to a Colleague Automatically
9. Automate Personalized Mail Merge in Gmail

Sounds good? Then let’s dive in.

What Is Gmail Automation?

Gmail automation is the use of built-in features and extensions to handle repetitive inbox tasks automatically — drafting replies, sorting and labeling incoming mail, sending templates, forwarding messages, and scheduling emails — so you spend less time in Gmail and more time on work that actually needs a human.

If you find yourself writing the same email twice, sorting messages into folders by hand, or forwarding emails to colleagues one by one, all of that can be automated. Gmail’s native tools cover templates, filters, and scheduled sending; AI-powered extensions like Mailmeteor add automatic reply drafting, smart categorization, and personalized mail merge on top.

What Should You Automate in Gmail First?

Before automating Gmail willy-nilly, it’s worth noticing what you actually spend your time on — that’s what tells you which Gmail automations are worth setting up first.

A few signs it’s time to automate:

• You write the same kind of reply over and over.
• You forward the same type of email to a colleague, every time it arrives.
• You dig through a pile of irrelevant messages just to find the ones that matter.

If any of those sound familiar, there’s almost certainly a Gmail automation below that saves you hours a week.

The 9 Best Ways to Automate Gmail

In the following section, I’ll walk you step-by-step through the best ways to automate Gmail, with examples for each.

1. Draft Replies Automatically with AI

The single biggest time cost in email isn’t reading — it’s writing. Most replies follow a predictable shape (acknowledge, answer, close), which makes them a good fit for AI to draft for you.

Gmail itself has started rolling this out natively through Gemini — “Help me write” and Smart Reply can generate a draft based on the email you’re replying to. Mailmeteor’s AI assistant works alongside this, drafting a full reply directly inside your Gmail thread based on the message you received, so your workflow becomes: open the email, review the AI’s draft, edit anything that needs a personal touch, and hit send.

Here’s how it works:

1. Open an email in Gmail with Mailmeteor’s Gmail extension installed.
2. Look for the AI draft/reply option next to your usual reply button.
3. Review the drafted response — edit tone, details, or specifics as needed.
4. Send as you normally would.

The time savings compound fast. Instead of composing 20 replies a day from a blank page, you’re editing 20 drafts that are already 80% of the way there.

2. Sort and Categorize Your Inbox Automatically

Gmail’s native tabs (Primary, Social, Promotions) do a rough first pass at sorting your inbox, but they don’t know the difference between a client email and a newsletter that happens to land in Primary.

Mailmeteor’s AI-powered categorization goes a level deeper, automatically applying smart labels to incoming mail — separating client replies, internal messages, and low-priority mail — so your inbox is pre-sorted before you even open it.

Here’s how it works:

1. Install Mailmeteor for Gmail and enable smart categorization from the extension’s settings.
2. Let it run for a few days so it learns the shape of your inbox.
3. Check your sorted labels instead of scrolling through one long list.

Combined with the AI drafting above, this is the closest thing to a self-triaging inbox. Mail gets sorted automatically, and replies are half-written by the time you open them.

3. Create Gmail Templates and Automated Canned Responses

If you ever find yourself writing the same email more than once, you need to start automating with templates.

Gmail templates are perfect for sending quotes, invoices, or canned responses to frequently asked questions. And I’m not talking about some fancy add-on software — this is built into Gmail itself.

Gmail templates let you write out an email and save it as a template to use over and over again. For the full walkthrough — including how many you can save and whether they work on mobile — see our complete guide to Gmail templates.

How to Enable Gmail Templates

1. On your desktop, open Gmail.
2. Click Settings (gear icon, top right) > See all settings.
3. Click the Advanced tab.
4. Find Templates and click Enable.
5. Click Save Changes.

How to Create a Gmail Template

1. Compose an email in Gmail.
2. Click the three dots inside the composer for more options.
3. Click Templates and Save draft as template.

Now, wherever you need to send a canned response in Gmail, you can reuse these templates.

How to Send Personalized Email Templates in Gmail

If you want to send the same template to hundreds of people while still addressing each recipient by name, use Mailmeteor’s template extension for Gmail.

Mailmeteor customizes your email template with fields like name and more — see how it works here:

4. Schedule Replies and Auto Follow-Ups

Another way to automate Gmail is to schedule emails to send in advance — for example, if you want an email to go out next Tuesday.

Next to the send button inside the email composer, Gmail lets you schedule an email for a specified time and date.

How to Schedule Send Emails in Gmail

1. Open Gmail on your computer.
2. Compose a new email.
3. At the bottom, next to the send button, click the down arrow.
4. Click Schedule and choose a time and date.

You can check all the emails you have scheduled, and make amendments, from the Scheduled tab on the left-hand side of your inbox.

How to Schedule Auto Follow-Ups in Gmail

Scheduling emails is great, but sometimes you’ll still miss a follow-up. That’s why I want to show you how to send emails with a follow-up that fires automatically if the person doesn’t reply within a set period of time — so you don’t have to remember to do it yourself.

Here’s how it works:

1. Install this extension for Gmail.
2. At the bottom, next to the send button, click the down arrow.
3. Click Send with a follow-up.
4. Choose when you want your follow-up to send.
5. Compose your follow-up email, or use a pre-written template.

5. Set Up Gmail Filters and Rules

I don’t know about you, but half the time I spend on email is doing things like:

• Deleting promotional emails.
• Forwarding emails to where they need to go.
• Sifting through what’s actually important.

Gmail filters and rules let you automatically delete, sort, reply to, or forward emails that meet specific criteria, so you never have to do it manually.

It works by defining a set of email criteria (like containing specific words, or coming from certain senders). Then, every email meeting that criteria does a certain thing, like:

• Automatically sorting emails into specific folders — newsletters, clients, accounting.
• Automatically deleting all emails containing the word “unsubscribe”
• Automatically forwarding a specific type of email to a colleague.

Let’s show you how to set this up now.

6. Move Emails to a Folder Automatically

With rules and filters, you can use Gmail labels to automatically sort incoming messages into folders — invoices, newsletters, promotional emails, or everything from clients and colleagues.

Here’s how it works:

1. Open Gmail on your computer.
2. Click the slider icon on the right end of the search bar.
3. From the pop-up, define the type of email you want to move to a folder.
4. Click Create a filter.
5. Select Apply a label and choose an existing label or create a new one.
6. All matching emails will now appear in that label folder on the left-hand sidebar.

7. Hide Promotional Emails from Your Inbox Automatically

If you’re anything like me, 80% of the emails you receive each day are either newsletters or promotions. Rather than sifting through them daily, you can get Gmail to detect these emails and hide them from view.

Here’s how it works:

1. Open Gmail on your computer.
2. Click the slider icon on the right end of the search bar.
3. In the “has the words” field, type unsubscribe.
4. Click Create a filter.
5. Select Apply a label to send them to a folder, or archive them.
6. Marketing emails should now sort automatically, since 99% of promotional emails contain the word “unsubscribe.”

8. Forward Emails to a Colleague Automatically

If you want to forward a certain type of email to a colleague — to flag a customer inquiry or catch an emergency — Gmail automation can forward specific emails to a designated address for you.

Here’s how it works:

1. Open Gmail on your computer.
2. Click the slider icon on the right end of the search bar.
3. In the “subject” or “from” field, define a way to detect your specific emails.
4. Click Create a filter.
5. Under Forward it, add a forwarding address.
6. Once set up, every matching email will automatically forward to that address.

9. Automate Personalized Mail Merge in Gmail

If you’ve ever sent a mail merge to colleagues, clients, or customers using Gmail alone, you’ll know the challenges:

• You can’t address each person by name.
• You can’t track opens, replies, or clicks.
• You can’t schedule a follow-up if they don’t open or reply.
• And if you’re sending a BCC, you risk clicking “reply-all” and breaching everyone’s privacy.

We built the Mailmeteor extension for Gmail to solve exactly this. Used by over 7 million users worldwide, it lets you send a personalized mail merge in three easy steps:

1. Select your recipients from Gmail, Google Sheets, or an Excel CSV.
2. Create an email template with personalized fields (name, and so on).
3. Add follow-ups and hit send.

Unlike other email platforms, Mailmeteor is built with simplicity and privacy in mind, and lets you log in with Gmail directly.

To show you how it works, here’s how to send an automated email from Google Sheets:
