Don't let your data train someone's AI.
Arlen Mail is end-to-end encrypted email that keeps your inbox yours. No scanning, no ad targeting, and nothing handed off to train a model on your private life.
Your inbox is the most honest record of your life.
Receipts, tickets, health results, the people you love. "Free" email pays for itself by reading all of it — to target ads, and increasingly, to train AI. We think that trade is a bad one.
You're not the product
Conventional providers scan message contents to build a profile of who you are — what you buy, where you go, what you worry about.
Your life is not training data
Private correspondence is being fed into models you never agreed to. Once it's in, it doesn't come back out.
Email that works the way you'd hope it already did.
Fast, familiar, and built so that your messages are readable by exactly one party: you.
End-to-end by default
Messages are sealed on your device and stay encrypted at rest. Mail between Arlen accounts is fully end-to-end — no setup, no PGP rituals.
You hold the keys
Your encryption keys never leave your control. Even we can't open your inbox.
Never scanned, never sold, never trained on
No ad profiling. No content analytics. Your mail is never used to train AI — ours or anyone else's. That's a contractual promise, not a setting buried in a menu.
Bring your whole inbox
Import from Gmail, Outlook, or any IMAP provider in a few clicks. Keep your address with custom domains, or get a clean @arlenmail.com one.
Familiar, and fast
Search, labels, filters, snooze, scheduling — everything you expect from a modern inbox, with encryption running quietly underneath.
Privacy that works in the background, always.
Arlen actively guards your inbox — blocking trackers, sealing what's sensitive, and giving you controls that put you in charge.
Ads and trackers, blocked in your inbox
Arlen strips spy pixels and ad beacons out of every message before they can load — so senders can't tell when, where, or how often you read.
Send mail that deletes itself
Set a message to disappear from both inboxes after it's read, or on a timer you choose. Perfect for passwords, documents, and anything you'd rather not leave lying around.
Attachments encrypted end-to-end
Files are sealed with the same key as your mail. The "Sealed" folder keeps your most sensitive threads locked, even on a shared device.
Three steps, and your mail is only ever readable by you.
No cryptography degree required. Here's the whole idea in plain language.
Locked on your device
Before a message is sent, your device encrypts it with a key only you possess. It leaves your laptop or phone already sealed.
Stored so we can't see it
On our servers your mail is just scrambled data. There's no plaintext to scan, leak, hand over, or feed to a model.
Opened only by you
When you sign in, the message is decrypted locally with your key. The lock and the key never live in the same place but your hands.
