|---|---|---|
| Your address | you@qeyet.com | you@qeyet.com |

| Sign in | Six recovery words | Username and password, optional two-factor |
| Where you read mail | QeyeT Mail on the web and Android | Any IMAP/SMTP app (Apple Mail, Thunderbird, Outlook, phones) |

Synced across your devices. Anyone you email appears — and QeyeT contacts are verified.
Security
QeyeT-to-QeyeT mail and Messages encrypt for your devices. Internet mail to Gmail still uses SMTP — we don't pretend otherwise.
How encryption worksSame address and six recovery words. Install over the previous version.
Quantum is end-to-end encrypted between QeyeT addresses, with keys on your devices and six recovery words instead of a password. Classic is standard email with a password, IMAP and SMTP; it is encrypted at rest but not end-to-end, so the server can process your mail. Compare them side by side.
Yes, as regular email. Mail from a Classic account to a Quantum user shows the sender as you@classic.qeyet.com, and replies reach your Classic inbox. Only mail between Quantum addresses is end-to-end encrypted.
Use your full address as the username. Incoming: classic.qeyet.com, IMAP port 993, SSL/TLS. Outgoing: classic.qeyet.com, port 587 with STARTTLS (or 465 with SSL/TLS). Full settings.
Yes. Personal Quantum @qeyet.com is free during preview, and Classic includes 1 GB free (5 GB paid plans are coming soon). Hosting on your domain starts free for a normal team pilot.
