Early access is open · $5/mo

Email, without the noise.

Screening

Strangers wait at the door

The first time someone writes to you, their message is held in a screening queue, not your inbox. Accept the humans, block the noise. Decisions sync through your account, so a sender you accept at your desk is already accepted on your phone.

  • Held, not deleted. Screened mail is fully readable while it waits.
  • Lookalike domains flagged. paypa1.com does not get to look like PayPal.
  • No notifications for strangers. Only accepted senders can interrupt you.

Illustration for your launch?

Hi! I saw the linen.email teaser and I do editorial illustration. A few samples attached, in case…

One decision per sender, remembered on every device.

Reading & replying

The thread on one quiet sheet

A conversation reads top to bottom on a single pane: attachments within reach, remote images stripped of trackers, and a reply field already waiting at the end. Search runs against the local index, so it works on a plane.

04 · AI, kept simple

AI, kept simple

The whole of it fits in one menu

No chat window, no prompts to engineer. Pick an action beside your draft (improve, summarize, add a TL;DR) or write your own in a single sentence with New action. The result streams in beside your words, you keep what's good, and nothing sends itself.

Ask
One action from a short menu, or your own one-sentence instruction.
Read
Only the text you chose travels: trackers stripped, zero-data-retention routing, never training data.
Run
Included credits, your own key, or a local model on your machine. Same menu either way.

SubjectSigned contract before Friday

Hey Sam, so basically just following up on the thing from last week because I know things got busy and it slipped, totally fine, but the invoice deadline is Friday and I still need the signed copy back from your side before we can send it out, so if you could get to that it would be great. Thanks!!

05 · Also in the box

Also in the box

Unified inbox

A Gmail, a Microsoft 365, and a self-hosted IMAP box, side by side and behaving identically.

Conversation threads

A thread is one row and one quiet sheet, with proper headers so replies land where they should.

Offline outbox

Send on a plane. Mail parks in the outbox and goes out on the next connection.

HTML signatures

Per account, with a live preview, applied at send time.

Attachments

Receive, preview, and send on all three protocols. No surprises at 25 MB.

Tracker stripping

Remote images are cleaned before they render. Senders learn nothing about your reading.

It's not about answering faster.

It's about reading in peace.

06 · The reward

The reward

An empty inbox greets you back

When nothing is selected, Linen doesn't show you an empty list. It says good evening, counts what's actually waiting, and leaves you alone. Inbox zero is a place you visit, not a chore you chase.

  • 0 bytes of your mail on our servers
  • 5 platforms from one codebase
  • 12 words to set up a new device
  • 100% readable offline

07 · Under the hood

Under the hood

Mail sync
Gmail API, Microsoft Graph, and IMAP/SMTP. Incremental sync with cursor recovery when a provider expires its history, so a stale device catches up cleanly instead of duplicating your mailbox.
Storage
Messages live in an encrypted database on your device. Keys are held by the operating system: Keychain on Apple platforms, DPAPI on Windows, Keystore on Android. Nothing readable sits on disk.
Offline
Reading, search, and composing work without a connection. Sent mail parks in an outbox and goes out on the next sync. If our servers disappear tomorrow, your mail still opens.
AI, on request
Improve a draft, summarize a thread, pull out action items. Runs only when you ask, on only the text you selected, over zero-data-retention routing. Nothing is used for training.
Bring your own model
Use the included credits, or plug in your own OpenAI, Anthropic, or OpenRouter key. Prefer nothing leaving the machine at all? Point it at local models through Ollama.
Multi-device setup
A 12-word phrase encrypts your account credentials for setting up new devices. We store only ciphertext. Lose the phrase and nothing is lost: you reconnect your accounts and carry on.
08 · Platforms & pricing

One client, five platforms

Mac, Windows, Linux, iPhone, and Android, from one codebase, with the same shortcuts and the same screening queue. Settings and signatures travel with your account. Your mailbox never does; each device syncs its own encrypted copy directly from your provider.

Multiple accounts sit side by side in one unified inbox: a Gmail, a Microsoft 365, and a self-hosted IMAP box behave identically.

Billed monthly through Stripe. Cancel anytime from settings; your mail is on your device either way.

09 · Privacy

Privacy, in plain words

Your mail syncs directly between your device and your mail provider, whether that is Gmail, Microsoft 365, or any IMAP service. It stays on your device, encrypted. Our servers handle your subscription, your AI credits, and your screening preferences. They do not store your mailbox.

AI features send content to a model only when you ask, and only the text you selected, stripped of trackers and unnecessary headers, over zero-data-retention routing. Prefer your own AI account or a local model? Both are first-class. Nothing is ever used for training.
