Key facts

  • Paid tier for unlimited accounts on two devices. Free for one account. No subscription.
  • Shows the real Gmail and Outlook web UI, so labels, filters and search operators work unchanged.
  • Sign-in on Google's or Microsoft's own page. No Smails server touches your mail. Not Electron.

Not for

Anyone wanting one merged unified inbox, IMAP support for providers other than Google and Microsoft, or built-in AI features

What is Smails?

Smails is a native desktop app for Mac and Windows that keeps multiple Gmail and Outlook accounts in one window. Each runs in its own isolated session showing the real Gmail or Outlook web interface, so labels, filters, search operators and shortcuts behave as in a browser. Sign-in happens on Google's or Microsoft's own page, so Smails never sees the password and mail goes directly between device and provider. Not a unified inbox: accounts stay separate. Free for one account, offers paid tiers.

Is Smails worth the price?

Great value

The pricing is exceptionally generous.

The Free tier gives a full-featured single account with no time limit, and the Unlimited tier is a one-time $9.99 for unlimited accounts on two devices, which is far cheaper than typical subscription-based email clients. Best for users who need multiple email accounts without recurring costs.

Smails FAQ

How does Smails help if I manage both a Gmail and an Outlook account?

Smails keeps multiple Gmail and Outlook accounts in one desktop window, each in its own isolated session showing the real web interface. You can switch between accounts without opening separate browser tabs or windows. Mail goes directly between your device and Google or Microsoft, and sign-in happens on the provider's own page.

How does Smails compare to Thunderbird?

Unlike Thunderbird, which typically pulls mail into a local client, Smails shows the real Gmail or Outlook web interface in isolated sessions, so labels, filters, search operators and shortcuts behave exactly as in a browser. Smails does not provide a unified inbox; accounts remain separate. It is a native desktop app available for Mac and Windows.

What are the trade-offs of Smails not being a unified inbox?

Smails deliberately keeps accounts separate rather than merging them into one chronological feed. If your workflow depends on seeing messages from all accounts in a single inbox, Smails does not offer that. The benefit is that each account's labels, filters, search operators and shortcuts work exactly as they do in the browser, without interference between accounts.

What kind of user does Smails fit best?

Smails fits best for individuals who regularly handle multiple Gmail or Outlook accounts and want them in one desktop window without losing the native web experience. It serves users who rely on Gmail's or Outlook's own labels, filters, search operators and shortcuts, because those work exactly as in a browser. Because accounts stay separate, it also suits people who need clear separation between work and personal mailboxes.

How is Smails priced?

Smails is available on a free tier for one account, with paid plans for more usage and features. The paid plans extend the number of accounts or capabilities you can use, with limits varying by tier. The product runs as a native desktop app on Mac and Windows.

Can Smails see my email password?

No. Sign-in happens on Google's or Microsoft's own page, so Smails never sees your password. Mail goes directly between your device and the provider. Each account runs in an isolated session showing the real Gmail or Outlook web interface.

Does Smails work with Gmail labels and Outlook search operators?

Yes. Smails displays the real Gmail or Outlook web interface in an isolated session, so labels, filters, search operators and shortcuts behave exactly as they do in a browser. There is no separate data model that could break these workflows.

How does Smails keep multiple accounts isolated from each other?

Each account in Smails runs in its own isolated session showing the real Gmail or Outlook web interface. This keeps cookies, sign-in state and account data separate, so you can stay signed in to multiple accounts at once. Accounts are not merged into a unified inbox.
