How to Add a Label in Gmail (And Actually Use Them Well)

Gmail labels are one of the most underused organizational tools in email. Unlike traditional folders, labels work more like tags — meaning a single email can carry multiple labels at once, giving you far more flexibility in how you organize your inbox. Here's a complete breakdown of how to create and apply labels, plus the variables that determine whether a simple or more advanced setup makes sense for you.

What Gmail Labels Actually Are

Before diving into the steps, it helps to understand what makes labels different from folders. In most email clients, moving a message to a folder removes it from your inbox and puts it in one place. Gmail labels don't move messages — they tag them. An email labeled "Work" and "Urgent" still appears in your inbox and shows up when you click either label in the sidebar. This non-destructive, multi-tag approach is more powerful but does require a small shift in thinking.

Labels appear as colored tags next to email subjects in your inbox, and as clickable categories in the left-hand sidebar.

How to Create a Label in Gmail (Desktop)

The full label creation process is only available on desktop — either in a browser or the Gmail web app.

Step 1: Open Gmail Settings Click the gear icon (⚙️) in the top-right corner, then select "See all settings".

Step 2: Go to the Labels Tab Click the "Labels" tab at the top of the Settings page. This shows all existing labels and gives you the option to create new ones.

Step 3: Create a New Label Scroll to the bottom of the Labels tab and click "Create new label". Enter a name, and optionally nest it under an existing label (more on that below).

Alternative shortcut: In the left sidebar, scroll down past your existing labels and click "Create new label" if that option is visible — or hover near the label section and look for the + icon.

How to Apply a Label to an Email

Creating a label is only half the job. You still need to apply it to messages.

From the inbox: Select one or more emails using the checkbox, then click the label icon (it looks like a tag) in the toolbar above your message list. Check the labels you want to apply and click "Apply".

From inside an open email: Click the label icon in the top toolbar, or use the "More" (three-dot) menu and select "Label as."

Using filters (automated labeling): This is where labels become genuinely powerful. Go to Settings → Filters and Blocked Addresses → Create a new filter. Set your criteria (sender, subject keyword, etc.) and choose "Apply the label" as the action. Every matching email will be labeled automatically — no manual sorting required.

How to Add a Label on Gmail Mobile

The Gmail mobile app (iOS and Android) lets you apply existing labels to emails, but you cannot create new labels from the app. Label management is desktop-only.

To apply a label on mobile:

• Open the email
• Tap the three-dot menu (top-right)
• Select "Label"
• Choose from your existing labels

This limitation matters if you're primarily a mobile user — you'll need to plan your label structure from a desktop session first.

Nested Labels: Folders Within Labels

Gmail supports nested labels, which function like subfolders. For example:

To nest a label, check "Nest label under" when creating it and choose the parent. This helps when you have a high volume of labeled email and want a cleaner sidebar hierarchy.

Label Colors and Visibility

You can assign colors to labels for quick visual scanning — right-click any label in the sidebar and select "Label color". Color-coding is especially useful when you're triaging a busy inbox and want to spot priority categories instantly. 🎨

You can also control whether a label appears in the sidebar, in your message list, or both — or hide it entirely while keeping it functional for search and filtering.

Factors That Shape How You'll Use Labels

This is where individual setup starts to matter. A few key variables affect how useful labels will be for any given person:

• Email volume: Light email users may only need two or three labels. High-volume inboxes — especially for anyone managing multiple projects, clients, or teams — benefit significantly from filters combined with labels.
• Gmail account type: Personal Gmail accounts and Google Workspace (formerly G Suite) accounts have the same label functionality, but Workspace admins can sometimes restrict certain settings.
• Workflow habits: Labels paired with Gmail's "Skip the Inbox" filter action (which archives emails as they arrive and applies a label) can essentially recreate a folder-style system if that's your preference.
• Use of third-party tools: If you use Gmail integrations like CRM tools, help desk software, or productivity apps, some of those tools interact with or generate labels automatically — worth knowing before you build an elaborate manual system.
• Multiple email addresses: If you manage multiple Google accounts, labels are entirely separate across accounts — there's no cross-account label sharing.

Searching by Label

Once labeled, emails are easy to find. In the Gmail search bar, type label:labelname (replacing spaces with hyphens for multi-word labels) to pull up every tagged message instantly. This becomes especially useful when labels are applied consistently over time and your archive grows.

How elaborate your label system should be — whether a handful of broad categories or a detailed nested hierarchy with color codes and automated filters — depends entirely on how you use email day to day, what you're tracking, and how much upfront setup you're willing to invest for long-term payoff.
