Mailwing showing six email accounts in one native window

Native is the point.

Mailwing isn't another browser pretending to be an app. Six providers, each in their real interface, sharing one window — with a few quiet upgrades a browser tab can't give you.

Six providers, one window

Gmail, Outlook, Zoho, Fastmail, Yahoo and ProtonMail — each in its real native interface, side by side in a single app.

Isolated sessions per account

Cookies, login state, and local storage never cross between accounts. Sign in to two Gmail accounts without the usual chaos.

Live unread counts, everywhere

Sidebar, dock, system tray and notifications stay in sync with each inbox — no need to click around to check what's new.

Built-in ad & tracker blocking

Network-level filtering quietly strips promo banners and tracking pixels. Provider domains are deliberately left untouched.

Dark mode follows your OS

Light by day, dark by night — Mailwing follows your system preference so you never have to flip a switch.

Notes & to-dos, right there

A quick scratch panel next to your inbox. Cmd/Ctrl + Shift + N opens it. Persists across launches, never leaves your device.

Install in one line.

Pick the channel that matches your OS. Mailwing is unsigned — first launch needs a single trust step per platform.

Or via Homebrew:

terminal
brew install --cask vinaysamtani/mailwing/mailwing

First launch: right-click Mailwing in /ApplicationsOpen. Why?

Or via winget:

powershell
winget install --id Mailwing.Mailwing

First launch: SmartScreen → More infoRun anyway. Why?

Then make it executable:

terminal
chmod +x Mailwing-1.2.1.AppImage
./Mailwing-1.2.1.AppImage

Set as your default mail client: xdg-settings set default-url-scheme-handler mailto mailwing

Common questions.

Is Mailwing actually free?
Yes. Free to download, MIT-licensed, source on GitHub. No paid tier, no "team" plan, no upsell.
Does Mailwing read my email?
No. Mailwing wraps your provider's own web interface in an isolated session per account — Gmail talks to Google, Outlook talks to Microsoft, and so on. Mailwing itself never sees your messages and routes nothing through any intermediary.
Why is the app unsigned?
Code signing certificates cost hundreds of dollars a year per platform. Mailwing is a one-person open-source project — until that changes, you'll see a first-launch trust step on macOS and Windows. The trade-off is full source transparency on GitHub.
Can I add a provider that isn't on the list?
Most webmail providers work if you can pin them — open an issue on GitHub with the provider URL and we'll look at adding it to the registry.
Is there a mobile app?
No, and there are no plans. Mailwing is intentionally a desktop app for people who do email at a keyboard. Use your provider's own mobile app for phone access.
Does Mailwing sync between my computers?
No. Accounts and notes live only on the machine where you added them. If you want them on another computer, sign in there too.

Stop juggling tabs.
