One Voice Mail is more than an email app. It replaces the core of your Google Workspace or Microsoft 365 subscription with Gmail-class mail, calendar, contacts, notes, Drive and Office-compatible Docs, Sheets and Slides — plus meetings, tasks, projects, diagrams, voice notes, polls, campaigns and native desktop apps for macOS, Windows and Linux. Twenty apps, one sign-in, on your own server.
Free downloads
Free for macOS, Windows and Linux. Use it standalone — no mail server, no account — as a full Office-compatible editor suite for your local files.
Why Mail
Google Workspace and Microsoft 365 bundle mail with calendar, contacts, files, documents, meetings and administration. One Voice Mail bundles all of it too — then adds Mail Desktop for macOS, Windows and Linux — but runs on your server, under your rules. Email is the master key to your digital life. You should hold it.
Gmail, Calendar, Drive and Docs are convenient — until the price changes, a policy shifts, an API closes or an account is suspended. Your work is tied to someone else's roadmap.
One Voice Mail runs on your server. Your domain, your accounts, your retention rules, your backups. Leave whenever you want, with standard formats intact.
Mail in one tab, calendar in another, files in a third, a document in a fourth. Every switch costs attention, and every tool charges separately for the same seat.
Twenty apps share one shell, one search and one sign-in. Turn an email into an event, a task, a document or a meeting without leaving the conversation.
The files you work on already live on your computer. A web app cannot open them where they are, cannot work on a train, and has no taskbar badge, native menus or file associations.
Mail Desktop is the same suite as a real desktop application for macOS, Windows and Linux. It opens without an account, edits local Office files, works offline and stays signed in.
“The alternative to rented productivity software is not a worse experience. It is a better one — because you control the terms.”

Every app shares the same design, search, notifications and keyboard model. Once you know one, you know them all — on the web, on your phone, and on your desktop.
Mail Desktop for macOS, Windows & Linux
Mail Desktop is the entire suite as a native desktop application — on macOS, Windows and Linux. The same screens and data, with the disk and the operating system brought into the product.
mailto:, Quick Look or Explorer preview, system search, Trash or Recycle Bin, printing and drag-and-drop with Finder or Explorer.Cold start ≤ 2.5 s · 10,000-item folders streamed · local backups kept 30 days
Privacy by design
Privacy is not a setting you trust a vendor to respect. It is what happens when the data never leaves your infrastructure in the first place.
Mail, files, calendars and backups live on infrastructure you choose. No data resale, no advertising profile, no training on your mail.
TLS in transit, encryption at rest, S/MIME and PGP for end-to-end mail. Your private keys stay in your browser, protected by a passphrase.
Summaries, drafting and search in words are off until you turn them on, run through your organisation's gateway, and are never used for ads.
IMAP, SMTP, CalDAV, CardDAV and WebDAV. Real .docx, .xlsx, .pptx, .graffle, .oplx files. Leave with your data whenever you want.
The suite
Mail is the front door, but this is the whole workspace: files, documents, spreadsheets, presentations, diagrams, plans, meetings, tasks, notes, voice notes, campaigns and polls. It covers the equivalent Google Workspace and Microsoft 365 productivity apps — and more.
Investors & partners
One Voice Mail is built and working: a self-hosted alternative to Google Workspace and Microsoft 365, with twenty connected apps, native desktop apps for macOS, Windows and Linux, and a proven migration path from Gmail and Outlook. We are now looking for investors and distribution partners who believe organisations should own their productivity stack.
Open to hosted, subscription and client-owned models. Our preferred model charges for pooled storage, not seats: €210 per TB per month, unlimited accounts, every app included — about half of Microsoft 365 or Google Workspace for a typical 100-person company.
