Encrypted email.
Aliases built in.
One protected inbox, an alias for every service. End-to-end encryption keeps the mail itself unreadable. Aliases keep your real address out of every database. Together: less spam, fewer leaks, and one calm inbox.
A different address
for every site that asks.
Pick a username. We'll show you how it lands on every domain in our pool. Hand out one alias per service — shopping, banking, work, signups — and your real address never enters another database. If a site leaks, you burn that alias. Nothing else moves.
One inbox. An alias for everything.
Sign up once. Keep your key.
One handle, one password, one OpenPGP key — generated locally on your device. You only ever manage one inbox.
$ create account handle = alex key = generated locally ✓ ready
A fresh address per service.
Stop reusing your real email. Generate an alias for every site that asks — each one routes back to the same inbox.
shop@quietbox.io → amazon, etsy bank@notmy.name → chase, n26 news@sidedoor.email → substack, rss signup@offgridmail.com → trials
One alias gone. The rest stay clean.
When a service starts spamming or gets breached, switch off that alias. The rest of your inbox keeps working. Your real address was never exposed.
from: [email protected] to: [email protected] ↳ disable alias ✓ ↳ spam route closed
Three layers between you and the leak.
Aliases keep your address out of databases. End-to-end encryption keeps the content of your mail unreadable. Per-alias controls keep spam from ever reaching the inbox.
End-to-end encryption
OpenPGP, performed in your browser. The body of every message is unreadable to anyone in transit — including us.
Aliases as a firewall
Each alias is a separate target. If a service is breached, only that address is exposed — the rest of your inbox stays anonymous.
Spam stops at the alias
Per-alias filters, rate limits and one-tap kill switches. When an alias goes bad, disable it — the rest of your inbox stays calm.
Zero-knowledge by design
Keys live on your device. No content logs, no behavioural tracking, no remote-image pixels. There's nothing useful to hand over.
Better than Hide My Email.
By design, not just by feature.
Apple's Hide My Email and Firefox Relay are a great first step. But they hand out addresses on one obvious domain — so spam knows, and your mail is still locked into one ecosystem. lowkeymail fixes both.
// product names belong to their owners. comparison reflects publicly-documented behaviour as of 2026.
Six services, one inbox. A coloured tag tells you which alias just got mail.
An ecosystem, built around private mail.
Private mail with end-to-end encryption, native key management, and no behavioural tracking. The core.
Aliases
A fresh address for every service. Stop reusing your real email — hand out aliases like business cards, and your real inbox stays clean.
Forwarding
Don’t want to live in an alias? Let it forward to the inbox — and still reply "from" it without exposing your real address.
AI Assistant
Sorts every alias by what matters — receipts, replies, noise. Drafts answers in your voice when a thread needs one. Runs on your device against decrypted mail, so we never see the content it reads.
Calendar
End-to-end encrypted scheduling, private invites, no third-party leaks. In the works.
Drive
Encrypted file storage and sharing, designed to live next to your mail attachments. Soon.
Password manager
A vault for the credentials behind your aliases. Same key, same client. Soon.
Pay for identities, not gigabytes.
The thing you really want more of is alias domains. So that's what scales with the plan.
