Visually it resembles Mail.app, but if it’s going for a similar level of functionality I think modern GNOME’s hamburger-and-three-dots-buttons approach to menus is going to become a problem.

This is one of those types of app that really benefits from a proper menubar with several top-level menus so the user isn’t stuck spelunking submenu tunnels.

I don't understand this mentality. It's an email client. There's not a lot needed UI-wise to make a functioning interface. Display a list of emails, show the full message when you open it, etc. I don't see anything functionally different between this email app and basically every other one I've ever used.

You've either got insane standards or are using email way different than I.

1. Being released on GitHub for a month does not mean it’s a month old.

2. Seems odd to assume instability by default without evidence.

> - can’t choose a sender email?! This is major dealbreaker, if you have many aliases or domains.

Ugh, this drives me nuts. It's the same reason why I stopped using my Supernote Nomad for email.

I use iCloud+ email with a custom domain. With that arrangement you authenticate to Apple's servers with your iCloud "primary address", like someone.somename@icloud.com. Then you can send and receive email with your custom domain email address, which is the one you're actually using. But not with Supernote, or apparently Penguin Mail. My Nomad will only send mail with my @icloud.com address, even though that's only used for authentication.

So yeah, I just stopped using it altogether. That's not my address. It's not how people reach me. It's literally just a username.

Thank you for testing on Fastmail for us.

I'll stick with the web UI in that case. Are you using any other clients on Mac or Linux?

Sandboxing should be handled externally by something like Flatpak

If you took the time to read, it is an optional feature and uses local models.

Then my 'amail' client seems to fit the bill.. (OSS, rust, I use it on Linux and haven't tested elsewhere) ..not really suggesting it – it's pretty barebones and just whatever I've needed, but you're welcome to it obviously! Especially if you have issues/PRs to spur me on to features I've wanted too...

Same here. While I'd rather not have an embedded AI chat window, is there a way to disable it?

Not visually similar to the app discussed here, but some TUI options:

And this is the one I use with Gmail, Outlook, Yandex:

It's vibecoded - new, large codebases are par for the course.

(This used to come at the cost of code quality, but increasingly does not.)
