7 Best Gmail Desktop Apps for Windows in 2026

We tested every desktop email client that works with Gmail. Here's what's actually worth installing — and what's just a Chrome tab wearing a trench coat.

Google has never made a desktop app for Gmail. They probably never will. So if you want your inbox in a real window — one that doesn't vanish into 47 browser tabs — you need a third-party client.

The problem? Most "Gmail desktop apps" are just web wrappers. They open Gmail's web interface inside an Electron shell and call it a product. That's not a desktop client. That's Chrome with extra steps.

We tested seven apps that actually connect to Gmail and give you a proper desktop experience. Here's how they compare.

Quick comparison

App	Connection	Price	3-Pane Layout	Templates	AI Drafting	Privacy
Thunderbird	IMAP	Free	Yes	Via add-ons	No	Good
Mailbird	IMAP	$3.25/mo	Yes	Yes	No	OK
eM Client	IMAP/EWS	Free (2 accts)	Yes	Yes	Built-in	Good
Kiwi for Gmail	Web wrapper	$30/yr	No (Gmail UI)	Gmail native	No	OK
Wavebox	Web wrapper	$8/mo	No (Gmail UI)	Gmail native	No	OK
Outlook (new)	Microsoft sync	Free	Yes	Yes	Copilot ($)	Low
ChainMail	Gmail API	$1/mo	Yes	Yes	BYOK	High

1. Thunderbird — the reliable workhorse

Thunderbird is the obvious starting point. It's free, open source, and has been around since 2004. The recent Supernova redesign (v115+) gave it a much-needed visual overhaul with a card-based message view and modernized UI.

The catch: Thunderbird connects to Gmail via IMAP, which means Gmail's labels don't map cleanly to folders. You get duplicate messages, confusing label behavior, and sync issues if you have a large mailbox. Push notifications are slow because IMAP relies on periodic polling.

Best for: People who want free, open-source software and don't mind IMAP quirks.
Skip if: You have a large Gmail archive or need real-time sync.

2. Mailbird — polished but pricey

Mailbird is probably the most-marketed Gmail desktop client. It looks great, supports unified inbox across multiple accounts, and integrates with apps like Slack, Todoist, and Google Calendar inside the email window.

The catch: At $3.25/mo (billed yearly) or $79.95 for a lifetime license, it's one of the more expensive options. It also uses IMAP, so you get the same Gmail label mapping issues as Thunderbird. And some users report it gets sluggish with large inboxes.

Best for: People who want a polished, app-integrated email experience and don't mind paying for it.
Skip if: You only use Gmail and don't need the integrations.

3. eM Client — the power user's choice

eM Client packs in everything: email, calendar, contacts, tasks, notes, and even built-in AI writing assistance. The free version supports two email accounts, which is generous enough for most personal users.

The catch: The free version shows a nag banner, and the Pro license ($50/yr or $120 lifetime) is needed for commercial use. It's also a heavier application — if you just want fast email, the extra features add bloat you don't need.

Best for: Power users who want email + calendar + tasks in one window.
Skip if: You just want a fast, focused email client.

4. Kiwi for Gmail — the web wrapper done right

Kiwi takes Gmail's web interface and wraps it in a native-feeling desktop window. You get the exact same Gmail experience, but in its own window with a dock icon, keyboard shortcuts, and multi-account switching.

The catch: It's literally Gmail's web interface. You don't get a 3-pane layout, message sorting, or any features Gmail itself doesn't have. If Gmail is slow in Chrome, it'll be slow in Kiwi too. At $30/yr, you're paying for a glorified browser tab.

Best for: Gmail fans who just want a separate window and don't want a different UI.
Skip if: You want actual desktop email features like 3-pane view or per-message sorting.

5. Wavebox — the multi-app browser

Wavebox is less an email client and more a "web app manager." It runs Gmail (and Slack, Notion, Asana, etc.) in separate tabs inside a Chromium shell. It's useful if you want all your SaaS tools in one window.

The catch: At $8/mo, it's the most expensive option on this list — and it's not really an email client. You're paying for a specialized browser. Gmail inside Wavebox looks and works exactly like Gmail in Chrome.

Best for: People who use 10+ web apps daily and want them organized in one place.
Skip if: You specifically want a better email experience.

6. New Outlook (Microsoft) — the enterprise default

Microsoft's new Outlook app comes pre-installed on Windows 11 and supports Gmail accounts. It's free, has a 3-pane layout, and integrates with Microsoft 365. If your company uses Google Workspace but you grew up on Outlook, this might feel familiar.

The catch: Microsoft routes your Gmail through their servers for sync, which raises privacy concerns. Gmail label support is incomplete. And the new Outlook lacks many features from classic Outlook (rules, VBA macros, offline PST support). It also pushes Copilot AI hard, which requires a separate Microsoft 365 subscription.

Best for: Windows users who want a free, familiar-looking client and are OK with Microsoft's data handling.
Skip if: You care about privacy or need Gmail-specific features like labels.

7. ChainMail — built for Gmail from scratch

Full disclosure: we built this one. ChainMail is a desktop email client built specifically for Gmail using Google's official Gmail API — not IMAP, not a web wrapper.

Why does the connection method matter? IMAP clients treat Gmail like any generic email server, which breaks labels, makes sync slow, and causes duplicate messages. Web wrappers just show you Gmail's existing interface in a frame. The Gmail API gives ChainMail direct access to your labels, threads, and messages exactly as Gmail sees them — with instant push notifications and zero sync issues.

What you get:

Classic 3-pane layout (folders, message list, reading pane)
Non-threaded view — see every email as its own row
Email templates with smart variables ({first_name}, {company})
AI drafting with your own API key (OpenAI, Anthropic, Google, Ollama, etc.)
Dark mode that actually themes email bodies
Local-first privacy — your data never touches our servers

The catch: It's Windows-only right now, it's in beta, and it only supports Gmail (no Outlook, Yahoo, etc.). If you need a multi-provider email client, this isn't it.

Best for: Gmail-only users who want a real desktop email experience with modern features and privacy.
Skip if: You need multi-provider support or use macOS.

So which one should you pick?

It depends on what you're actually looking for:

Free and don't care about polish? Thunderbird.
Want Gmail's exact UI in a window? Kiwi for Gmail.
Need email + calendar + everything? eM Client.
Want a proper desktop client built for Gmail? ChainMail.
Company already pays for Microsoft 365? New Outlook.

The biggest mistake people make is picking a web wrapper and wondering why their "desktop app" still feels like a browser tab. If you want actual desktop email features — 3-pane layout, keyboard shortcuts, template management, offline access — you need a real client, not a wrapper.

Frequently asked questions

Does Google make a desktop app for Gmail?

No. Google has never released a dedicated Gmail desktop application. The closest official option is creating a Chrome PWA shortcut, which opens Gmail in a minimal browser window. For a true desktop experience with features like a 3-pane layout and email templates, you need a third-party client.

Why do some Gmail desktop apps have sync issues?

Most desktop clients connect to Gmail via IMAP, a protocol designed in 1986. Gmail's label system doesn't translate cleanly to IMAP's folder structure, causing duplicate messages and missing labels. Clients that use the Gmail API (like ChainMail) avoid these issues entirely because they speak Gmail's native language.

Are web wrappers real desktop apps?

Technically, yes — they run as separate applications on your desktop. But functionally, they're just Gmail's web interface in a specialized browser. You don't get desktop-specific features like a 3-pane layout, per-message sorting, or local templates. If you're happy with Gmail's web UI and just want a separate window, a wrapper works. If you want more, you need a native client.

Is it safe to connect Gmail to a third-party desktop client?

It depends on how the client connects. Apps using Google's official OAuth flow (where you sign in via Google's own login page) are safe — they never see your password. Apps that ask for your password directly should be avoided. Check that the client is verified by Google (look for the green checkmark during sign-in) and only requests the permissions it needs.
