How to create a label in Gmail on Mac: browser steps for Safari and Chrome

Gmail on a Mac runs in your browser

Google does not make a Gmail app for Mac. You read and sort mail in a browser, the same way you would on a Windows PC or a Chromebook. Open Safari or Chrome, go to mail.google.com, and sign in with your Google account. Every label step in this guide happens on that web page.

That has two practical effects. Gmail's menus live inside the page, not in the menu bar at the top of your Mac screen. Gmail's settings and shortcuts only work after the page loads and you are signed in. If a step seems to be missing, check that the tab shows mail.google.com.

What a label does and how many you can make

A label is a tag you attach to email. Labels sit in the left sidebar, and clicking one shows every message with that tag. Most people use them the way they would use folders, for clients, projects, receipts, or travel. Keep the names short so the sidebar stays readable.

Google's help article says Gmail allows up to 5,000 labels. Few people get anywhere near that. The limit that causes real trouble is color, and that gets its own section below.

Create a label step by step

The steps in this guide follow Google's own help article for the web version of Gmail. Follow them in order and you should land in the same place every time. Once you know where the icon sits, the whole process is a few clicks.

The create dialog is small. It has a name box, an optional Nest label under box, and a Create button. It does not ask for a color. Many people expect one, so they go looking, and the color step is actually a later menu.

Nest a label under a parent

Nesting puts one label inside another. A freelancer might use Clients at the top, then one child label per client. The child sits under its parent in the sidebar, so related mail stays grouped.

To nest, tick Nest label under when you create the label, then pick the parent from the list. Google's article does not state a maximum nesting depth or a maximum name length. Before you build a deep tree like Work > Clients > Acme > Invoices, test two or three levels and check how the sidebar looks on your screen.

Nesting is optional. A flat list of labels is easier to scan than a tree you cannot remember building. Start flat, and nest only when a group clearly belongs together.

Give a label a color

Hover over the label in the sidebar, click More, then choose Label color. The same menu offers Edit and Remove label. Read the menu before you click, because the options sit close together.

Gmail allows up to 100 custom label colors. Each combination of background and text color counts as one. If a new custom color won't save, you have probably reached that limit. Pick a standard color, or reuse a custom color you already made, and the save should go through.

Treat custom colors like a budget. Pick a small set and give each one a job, such as red for overdue clients or grey for archived work. A color that means three things stops helping you.

Use keyboard shortcuts with labels

Three label shortcuts speed up sorting. They only work when keyboard shortcuts are turned on.

• l opens the label menu for the selected mail, so you can apply a label.
• v opens the move to menu, which moves the mail to a label.
• g then l goes to a label. Press g, release it, then press l.

Turn shortcuts on from Settings gear > See all settings. Scroll to Keyboard shortcuts, select Keyboard shortcuts on, and click Save Changes. Google's shortcut page says Mac and PC differ, with Ctrl used on a PC where Mac uses ⌘. None of the three label shortcuts use ⌘, ⌥, ⌃, or ⇧.

The only Mac-only shortcut on that page is ⌘ ; for the next misspelled word. It is not a label shortcut, but it sits on the same list, so you may see it while you read.

Show and hide labels in the sidebar

A label can exist but stay out of the sidebar. Go to Settings > See all settings, open the Labels tab, and click Show or Hide next to the label. Google describes this as showing or hiding a label in the label list.

Show or Hide changes what the sidebar displays. Use Edit or Remove label from the More menu when you want to change the label itself. Hiding a label is the safer move if you only want a shorter list.

How labels behave in conversation view

Conversation view groups replies into one thread. Google's article says that with conversation view on, a label applies only to existing messages, not to new replies.

Here is a worked example. You label a client thread on Monday. The client replies on Tuesday. That reply does not pick up the label, so a view built around that label can miss it. Check the thread before you archive it, and label the reply by hand.

With conversation view off, a label applies only to the specific messages you labeled. Test one thread before you rely on a label to catch every reply. A quick test saves a lot of missed mail.

Mistakes people make with Gmail labels

• Looking for a color in the create dialog. Set color afterward with More, then Label color.
• Hiding a label to delete it. Show or Hide only changes the sidebar list.
• Clicking Remove label without reading the menu, since it sits next to Edit and Label color.
• Building a deep nest before checking how the sidebar looks on screen.
• Thinking the l key is broken when keyboard shortcuts are still off.

A simple habit prevents most of these. Create the label, check the sidebar, and only then add a color or a nest.

Make Gmail open in its own window with Safari

Safari can turn a website into an app icon in the Dock. Open mail.google.com in Safari, click the Share button in the toolbar, choose Add to Dock, then click Add. The Gmail icon then appears in the Dock and in Applications.

This is a Safari web app. It is not a Google app, and Google does not publish it. Apple's guide says that if you were signed in to the website in Safari, you are usually signed in to the web app too. It loads the same Gmail account, so your labels are the same.

Apple's Safari guide has a version selector that lists macOS Sonoma 14, Sequoia 15, Tahoe 26, and macOS 27. The guide does not say which version added Add to Dock. Check Safari on your own Mac before you plan around a specific version.

Chrome users: what carries over

Google's help article covers the Gmail web app, not one browser. The label steps should match in Chrome, and Settings and shortcuts should behave the same once the page loads. This guide did not verify Chrome-only steps for installing a Dock app, so use Safari for that option.

Next steps after you create a label

A label on its own only sorts mail you move by hand. To send new mail to a label automatically, build a filter. The steps are in how to create a filter in Gmail on Mac.
