AI Summary

OneMail is a desktop email application that brings all your email accounts into one place. It works completely offline by storing emails on your computer, keeps your passwords encrypted and secure, and lets you read, write, and organize emails with a clean interface similar to Gmail. You can connect many email providers (Gmail, Outlook, QQ, NetEase, and many others), filter emails quickly, and safely preview HTML messages without being tracked. Everything stays private on your device, and you can back up or restore your data anytime.

How It Works

1
📧 You download and install OneMail

🔑 You connect your email account

You click 'Add Account' and choose your email provider from the list. The app helps you enter your email address and password securely.

3
🔒 Your password is encrypted automatically

The app locks your credentials with strong encryption so they stay safe on your computer, never sent anywhere else.

4
📥 Your emails sync to your computer

The app quietly downloads your emails from your provider and stores them locally, so you can read them even without internet.

AI-Generated Review

What is one-mail?

OneMail is a desktop email client that keeps your mail local. Built with Electron, React, and TypeScript, it connects to your accounts via IMAP and stores everything in a local SQLite database. You get a unified inbox across multiple accounts, fast filtering by unread/attachments/starred, and a Gmail-style composer for composing and replying. Attachments stay as metadata until you explicitly download them, and HTML emails render in a sandboxed preview that blocks remote images by default. Your credentials are encrypted with AES-256-GCM, and you can export or import the entire database as SQL for backup.

Why is it gaining traction?

The local-first approach is the hook. Unlike webmail or cloud sync clients, your mail headers and bodies live on your machine. The safe HTML preview is a genuine privacy win -- no more tracking pixels firing when you open a newsletter. The SQL backup feature is rare in this space: you own your data in a portable format. Provider presets for Gmail, Outlook, QQ, NetEase, and dozens of others mean you do not hunt down IMAP settings. The read-state sync (marking messages read locally and pushing that back to the server) is a thoughtful touch for power users.

Who should use this?

Developers who want a privacy-respecting desktop mail client with local data ownership. Power users managing multiple personal accounts who need unified inbox and fast filtering. Anyone frustrated with webmail tracking and wanting a clean, configurable alternative. Organizations with compliance requirements that demand mail never leaves the local machine.

Verdict

OneMail solves real problems, but the 1.0% credibility score and 17 stars tell the story: this is early-stage software. The tech stack is modern (Electron 39, React 19, TypeScript 5.9), the feature set is solid, and the AGPL license is clear about what you can do with it. Test coverage exists but documentation is sparse. Worth watching, but wait for a stable release before betting your workflow on it.
