Qmail

by QENTRA Running

Your 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.

Running

Live. In daily use on the web and on Android; the self-host bundle ships with each release.

Thirty minutes, on your own data

Not a slide deck. We load your catalogue, your bookings or your estate, and you drive.

A demonstration is a working session on the thing you actually run. If it does not fit, you will know in half an hour, and nothing is owed.
