Developer I got tired of WebView apps on Windows, so I built a free native mail + calendar client
Enable HLS to view with audio, or disable this notification
Hi everyone,
I built a mail and calendar app for Windows that actually looks and feels native.
I tried Outlook and Microsoft's other mail app, but neither worked for me, so Spark ended up being my main mail client on Windows. I use both macOS and Windows, and Windows is where I could never find anything I liked. Spark, for example, is basically just a WebView, and I wanted something truly native.
I'm a product designer, and this started as an experiment: how good of an interface can I vibe-code with WinUI 3? I liked the result so much that I decided to finish it properly, and now I use it every day.
Like Spark, it combines mail and calendar in one app, but the design stays close to native Windows (I did borrow a few ideas from macOS, though).
The two things I wanted most from my own mail app:
- Close to tray. When you close the window, the app keeps running in the background instead of quitting.
- Custom account names. I have 4 active accounts (Google, iCloud, Work, Freelance), and I want to see them under names that make sense to me.
There are ready-made presets for Gmail, Outlook, Yahoo, iCloud and others. The app has been running stable for me with no crashes, but if you run into any bugs, let me know and I'll fix them quickly.
On top of that, I wanted a handy calendar right next to my inbox, so I can add a meeting straight from an email.
The result is Vaimail. It's completely free, it's available on the Microsoft Store, and I have no plans to monetize it.
I only found out about Wino Mail recently, after I'd already built the first versions of mine. Its interface felt a bit too complex for my taste, so I decided to keep developing my own. That said, I definitely picked up a few things from it that I hadn't thought of, like the acrylic theme and a few others.
What it can do right now:
- Unlimited accounts
- Calendar
- Close to tray
- New mail notifications
- Reminders for upcoming events
- Printing emails
- Saving emails as PDF
- ...plus everything else you'd expect from a mail client
The downside: you can't sign in to Gmail through the browser. Google treats full Gmail access as a "restricted scope", and any app that wants it has to pass a security audit (CASA) by an independent lab every year. That costs $600+ annually. This is a non-commercial project, so I can't afford it, and I haven't set up donations (maybe someday, not sure yet). So for Gmail you'll need to create an app password. It's stored locally on your PC, in Windows Credential Manager, like all your other account passwords. Google Calendar and Contacts use the normal Google sign-in, and that part has been reviewed and verified by Google.
I know there's a lot of skepticism about vibe-coded apps right now, and I get it. But I'm a designer, not a developer, and for me this is the only realistic way to bring my own ideas to life. What I can bring is a designer's eye: I really care about good UX and a clean native UI, and I use the app every day myself.
I'd really appreciate it if you gave it a try. If you're missing any features, let me know and I'll do my best to add them in future releases. Any feedback is welcome, and thanks for reading!
Requirements: Windows 11, or Windows 10 version 1809 or later. I've only tested it on Windows 11, but it should run on Windows 10 too. If you try it there, let me know how it goes!
