Why Smails
It's the real Gmail — labels, search, filters, chat — wrapped in a tiny native shell that respects your Mac.
Each Gmail gets its own private, isolated session. Sign in once; stay signed in. No cookie collisions, ever.
Every inbox stays warm in the background. Flip between accounts with a click or ⌘1–9 — no reloads.
Native Swift + WebKit. No bundled Chromium, no hundreds of megabytes. It starts fast and stays out of the way.
Click a link in an email and it opens where it should — your real default browser, not trapped in the app.
Make Smails handle mailto: links. Clicking one pops a quick account picker and Gmail's compose, pre-filled.
Real profile photos, unread badges, the interface you know. Nothing to relearn, nothing to sync.
Pricing
Try it with your main account for free. Pay once to add as many as you like — no subscription.

Good to know
No. You sign in to Google directly — exactly like in a browser. Smails never sees your credentials; your session lives only on your Mac, in its own sandbox.
No. Smails is an independent app that loads Gmail's own web interface. It isn't affiliated with, or endorsed by, Google. "Gmail" is a trademark of Google LLC.
A Mac running macOS 15 (Sequoia) or later. That's it.
A Pro license is a one-time purchase that activates on up to 2 Macs. It works offline; it just checks in occasionally to stay valid. Lost your key? You can recover it any time from your purchase email.
No, Google doesn't make a native Gmail app for macOS. Most people end up with browser tabs, a heavy Electron wrapper, or a full email client. Smails is the lightweight native app that just runs Gmail itself, with every account in one window.
No. Smails is a one-time purchase of $9.99, with free updates. Free with one account, pay once to add as many Gmail accounts as you like. No monthly fee, ever.
Yes. If you loved Mailplane for keeping all your Gmail accounts in one native Mac window, Smails is the closest successor: native, one-time price, multi-account. Mailplane shut down because Google blocked old embedded-browser sign-in; Smails uses Google's normal, current sign-in, so it doesn't hit that wall.
