Qmail
by QENTRA RunningYour mail, on your terms.
A webmail that connects to the mailbox you already have — Gmail, iCloud, Outlook, Yahoo, your own domain — and gives it a fast, private client on the web and on Android. Multi-tenant, so a team or a family signs up on one install; self-hostable for those who want the server too.

The interface
What it looks like to work in.
A drawing of the real layout, not a screenshot — the product sits behind a sign-in, and we will not fake one. Ask for a demonstration to see the live one on your own data.
What it does
- Connect the mailbox you already have over IMAP — Gmail, iCloud, Outlook, Yahoo, a Proton bridge, your own domain
- Multi-tenant from the ground up: anyone can sign up and connect their own account
- Messages rendered in a sandbox with scripts disabled — a mail can never run code in your browser
- A real Android app, kept in step with the web build
- Qalendar alongside, on the same account
- A self-host bundle for those who want the server on their own machine
Chapter 01
The mailbox stays where it is.
Qmail is a client, not a new address. Your mail keeps living with your provider; what changes is the speed and the privacy of the thing you read it in.
Chapter 02
Built defensively.
Every message is rendered inside a sandbox with scripts disabled. Output is escaped, writes are atomic, and no request runs without a tenant context — a mailbox can never see another.
Chapter 03
Run it yourself, if you prefer.
The same code ships as a self-host bundle. One server, your data, and the same client on the web and on Android.
Who it is for
People and small teams who want a fast, private mail client without changing address — and businesses that would rather host it themselves.
Live. In daily use on the web and on Android; the self-host bundle ships with each release.
