It's in the backlog, will be available pretty soon

thank you :)

might be an idea, we'll see, not needed to be a counterpart :)

this is my daily driver, and I want to keep maintaining it for the foreseeable future, I agree there are lot's of apps that end up dying. But that's not the case for Penguin Mail. And to clarify, I have used AI to develop parts of Penguin Mail, but I've also contributed a lot of code, I've been a developer for the last 30+ years and I think AI is a tool to increase productivity, embrace it :)

hey, what would be a nice to have? I'm gathering as much feedback as possible to make this client a goto client for everyone

currently submitted for Google review, takes some time, thak you tho

I appreciate all feedback shared here, would love to have it on GitHub so I can sort it out

thank you all :)

JMAP will be available in the next versions, currently working on a few of the backlog items and that's one of them

Thank you for those ideas, very good feedback and definitely something I'll add to the backlog

Fastmail is not something I use as default, so I had to check a lot of documentation, and some of the Fastmail features are probably missing, I'll have some of these on the coming versions

I need to update that intro, that's how the app started, it's very different now.

I use Penguin as my daily driver, and I made it exactly because of what I was missing on other mail clients, but idea after idea brought me here to share it with everyone, my intentions are to continue development and not keep it stale or let it die, there are loads of things i want to add but I also don't want to lose any stability, a nice balance is what I'm looking for

I use AI to aid with development, yes, thanks to this it has boosted my productivity by a lot, but to say it's completely vibecoded, not quite. but thank you :)

would love to get your feedback, how is it running? FreeBSD is not something I tried, but would love to know if you're having issues

the instructions are for the task I assign to Claude, most of the times it was stopping for feedback, I prefer to check in the end rather than spoon feeding it

Has AI functionality available if you enable it, but doesn't come bundled with anything, you connect your local LLM or Claude if you have to, you can also use OpenRouter or whatever you want, go cloud or go local, up to you (if you're interested in AI), otherwise, disable it

With AI is just, you can connect a local model, it has the ability but doesn't come bundled with nor it will be in future

this is actually on the pipeline of features, thank you tho

Penguin Mail is a mail and calendar app for Linux, written in Rust with GTK 4 and libadwaita. It's designed to be a lightweight, privacy-first alternative to Thunderbird or GNOME's built-in email.

What it does: • Aggregates Gmail, Microsoft (Outlook/Hotmail/Microsoft 365), Fastmail, iCloud, Yahoo, and any IMAP/POP3 account into one inbox • Calendar support for every account (Google Calendar, CalDAV) • Contacts with CardDAV integration • OpenPGP and S/MIME signing/encryption — keys never leave your machine • Gmail-style categories bar (Primary, Updates, Promotions, Social) • Send Later, Undo Send, templates, Markdown compose • A built-in AI assistant that can summarize threads, draft replies, manage rules, and search calendars. It runs on a local model (Ollama/LM Studio), an Anthropic API key, or Claude Code — you pick per job • Remote content blocked twice (WebKit filter + CSP), JS off by default • Runs in the tray at ~55 MB

It's GPL-3.0 and available as .deb, .rpm, Arch package, snap, tarball, and Flatpak. Not on Flathub yet — that's next.

We built it because existing Linux email clients felt bloated or didn't respect privacy. The AI assistant is a nice-to-have but not required — the app works great without it.

Feedback welcome: install experience, missing features, anything confusing. Happy to answer questions about the Rust/GTK4 architecture too.
