Sealwax 1.2.0 is a free, MIT-licensed mail client built for Omarchy
A native GTK 4 mail app in Rust that follows your Omarchy theme, works from the keyboard and never runs a script from a message. Its author says it has shipped 28 releases in four weeks.

Omarchy has a mail client made just for it. Sealwax is “a fast, minimal email client for Omarchy”, written in Rust with GTK 4 and libadwaita, and it follows your live Omarchy theme and font. It comes from Fredrick Thorsen, who publishes his Omarchy apps as PixDevs, an independent studio in Norway. He announced it on X on October 10, 2026, calling it “my own mail client for Omarchy” and “still a work in progress”.
It has been moving fast since then. Thorsen wrote on X on November 7, 2026 that Sealwax had reached 1.1.9 with “28 releases in four weeks, lots of them user requests”. About nine hours later came Sealwax 1.2.0, released on November 7, 2026. It fixes a list that used to jump around in the Group by Sender and Group by Domain views: the selected row now stays where it is on screen, and the arrow keys carry on from there.
According to the README, you type your email address and Sealwax finds the servers itself. It supports IMAP with IDLE push and an offline copy of your mail, plus POP3 into local folders. Outlook.com and Microsoft 365 use Sign in with Microsoft. iCloud, Fastmail, Yahoo and others use app passwords. Gmail works too, but only with an app password: there is no Sign in with Google.
The newer features are all about taming a busy inbox. You can unsubscribe from a newsletter in one click, group any folder by sender or by domain and archive or delete a sender’s mail all at once, and pin the senders you can’t afford to miss so their mail stays at the top. Rules are written in Sieve, either from a Rules dialog or by hand. Sealwax is built for the keyboard, with one-key shortcuts, a command palette on F1 and your own bindings in keys.toml.
It is careful with your mail. The README says no script in a message ever runs and nothing remote loads until you allow it, per message or per sender. Passwords and tokens live only in your keyring, and there is no telemetry. The changelog adds that Sealwax never checks for updates on its own, only when you pick Check for Updates… from the menu.
So, is it free? Sealwax is released under the MIT license. We looked for a price, a subscription, a donation link or a paid tier in the README, on the Sealwax page on pixdevs.com and in the GitHub repository’s details, and found none. One thing to know if you use Microsoft: the published packages include the author’s own Microsoft client ID, so you don’t have to register anything. But the publisher isn’t verified with Microsoft yet, so a work or school account from another organization may hit a “Need admin approval” page until that organization’s admin gives consent. The Microsoft sign-in notes explain how an admin can do that. Personal Outlook.com accounts aren’t affected.
Installing it takes one pacman package from the GitHub releases. The README’s one-liner downloads sealwax-x86_64.pkg.tar.zst and installs it with sudo pacman -U, and running the same line again updates it. Sealwax requires x86_64, and the 1.2.0 release only has x86_64 builds, so there’s nothing yet for ARM machines.
The repository had 79 stars and 10 forks on November 8, 2026, and the README thanks a handful of users whose reports, ideas and pull requests shaped the 1.1 series.
