Premail

Your inbox, defended.

AI email filtering for Mac, Windows, and Linux

Premail is a companion app that runs in the background, next to whatever email client you already use. It watches your Gmail, Outlook, and iCloud inboxes and handles mail the way you would by hand. No plugins. No new app to live in. Your inbox just stays calmer. See how to organize Outlook email without filing by hand.

A look inside

One window. Every inbox you own.

The Premail Rules screen showing Cold Email, Newsletter, Spam, and Marketing rules. Each has an on/off toggle, a filter-strength slider, and a row of actions - Archive, Trash, Move, Quarantine, Label, and Mark as Read.
Every rule has its own filter strength and its own action. Turn one off, dial it back, or change what happens when it matches.
The Premail Accounts screen listing four connected inboxes - iCloud, Outlook, and two Gmail accounts - each showing Connected status, an Enabled toggle, a Learning/Live mode switch, and auto-reply controls.
Connect Gmail, Outlook, and iCloud accounts side by side. Each one has its own enable switch and its own Learning or Live mode.
The Premail Analytics dashboard showing 2,039 emails handled, 6 hours 37 minutes saved, and 11.7 seconds saved per email, above a stacked bar chart of daily activity and breakdowns by action and by account.
Premail Pro keeps a running tally of what it handled and an honest estimate of the triage time it saved you.

What Premail actually does

Most email tools ask you to move in. Premail does not. It sits in your menu bar or system tray and works on the inbox you already have, in the client you already use, whether that is Apple Mail, Outlook, Thunderbird, or a browser tab. When a new message arrives, Premail reads it, decides what kind of mail it is, and applies the rule you set for that category - archive it, trash it, move it to a folder, quarantine it, or leave it alone.

The classification runs against an AI model of your choosing. You bring your own Anthropic or OpenAI key, or you point it at a local Ollama model and nothing leaves your machine at all. There is no Premail server in the middle reading your mail, because there is no Premail account: you download the app and it talks to your mail provider directly. That is the whole difference from cloud filtering services, and it is why we publish a Trust Center and a third-party security assessment rather than asking you to take it on faith.

It is built for people whose inbox has stopped being useful: engineers buried in recruiter outreach, founders drowning in cold email, anyone with a decade of newsletters they never unsubscribed from. If you have tried organizing your inbox by hand and watched it refill in a week, that is the problem this solves - not by giving you another folder system to maintain, but by handling the mail before you ever open the client.

Nothing is destructive by default. Every account starts in Learning mode, where Premail shows what it would have done without touching a single message, so you can check its judgement against your real mail before you hand it the keys. The Activity log records every decision it makes, and an allowlist guarantees the senders you care about are never filtered at all.

Premail runs on macOS, Windows, and Linux, and it is free for up to two personal inboxes. Pro adds professional inboxes, unlimited custom rules, and Reputation Shield, as a subscription or a one-time Lifetime license. If you are weighing it against a hosted service, the SaneBox comparison lays out where each one genuinely wins.

Safe by default

Every account starts in Learning mode

Before Premail touches anything, it watches. In Learning mode it classifies your new mail and shows exactly what it would do, without moving, archiving, or trashing a thing. When you trust the results, flip an account to Live and Premail starts acting on its own.
