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

Your inbox, on the wing.
All your email accounts, in one native app.
Mailwing puts your real Gmail, Outlook, Zoho, Fastmail, Yahoo and ProtonMail inboxes into one native desktop window — with live unread counts and notifications across every account. No browser tabs, no new client to learn.
Native is the point.
Mailwing doesn't reinvent your inbox. It loads each provider's real web interface — the exact Gmail or Outlook you already know — and gives all six one shared native window, with a few quiet upgrades a browser tab can't.
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. macOS builds are signed and notarized; on Windows the first launch needs a one-time SmartScreen confirmation.
Or via Homebrew:
terminal
brew install --cask vinaysamtani/mailwing/mailwingSigned & notarized by Apple — opens with a normal double-click. Details
Or via winget:
powershell
winget install --id Mailwing.MailwingFirst launch: SmartScreen → More info → Run anyway. Why?
Then make it executable:
terminal
chmod +x Mailwing-1.2.3.AppImage
./Mailwing-1.2.3.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.
Is Mailwing signed and safe to open?
On macOS, yes — Mailwing is signed with an Apple Developer ID and notarized by Apple, so it opens with a normal double-click. On Windows there's no code-signing certificate yet, so SmartScreen still shows a one-time "More info → Run anyway" step on first launch. Either way, every build is produced in the open by GitHub Actions, so you can audit exactly what shipped.
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.
