No. Email bodies, drafts, and attachments stay in your IMAP provider (Gmail, iCloud, Outlook, etc.) and in a fast SQLite cache on your machine. Entilio talks directly to your provider for mail — full message content never touches our infrastructure. What does sync to your Entilio account is the relationship layer (entities, tags, todos, account settings) and a short note of each action you take — the subject, sender, date, and what you did (moved, archived, tagged, deleted). Untouched emails leave no trace on our servers, ever.

Two reasons. First, you want a lasting history — "what did I do with that PHILIPS order confirmation last month?" — and it has to make sense to you when you read it, which means having the subject line in it. Second, the suggestion engine that powers Entilio's one-click move and unsubscribe bars learns from your past actions. The subject line gives that learning enough context to be useful without ever needing the body content.

They're invisible to us. If you never move, archive, delete, or tag an email, nothing about it ever syncs to our servers. Your history only fills up with what you've actually done.

Two reasons: safety and portability. If your laptop dies tonight, signing into Entilio on a new machine restores every entity you've built, every move pattern Entilio has learned, every tag, every todo. That layer represents months or years of relationship work — losing it to a hard drive failure isn't acceptable. Mail content doesn't need to sync because your IMAP provider already holds it.

No. Entilio is a paid product with a 30-day free trial. You get every feature for thirty days with no credit card. After that, pick monthly or yearly billing (yearly saves 17%). We don't do feature gating or "premium tiers" — there's one product and one experience.

Both Mac and Windows, available now — a native Mac app for Apple Silicon and a native Windows app for 64-bit Windows 10 and 11. Your Entilio account and full relationship layer (entities, tags, todos, action history) are the same on either one, so you can move between them and pick up exactly where you left off.

Gmail, iCloud, Outlook 365, Fastmail, Proton Mail Bridge, and any IMAP-compatible server. Custom domains hosted on the major providers work out of the box.

No setup is required. Entilio learns from the actions you already take — moves, archives, tags, unsubscribes — and surfaces them as one-click suggestions. The longer you use it, the smarter the suggestions get.

Most email apps optimize the same old model. Some chase speed with keyboard shortcuts. Some reorganize your inbox around screened/feed/paper-trail categories. Some turn email into chat. Entilio is the first email app whose foundational unit is the entity — every person and company you correspond with — and whose intelligence comes from your own history, not a generic algorithm.

An entity is a person, company, or organization that you correspond with. Entilio creates one automatically the first time a new sender appears, and it groups related addresses (a company's billing@, support@, and named employees) into a single entity so your relationship history stays unified.

Yes — on any mix of Macs and Windows PCs. Sign in on another machine and your entities, tags, action history, and account settings appear immediately. Mail is re-fetched per device from your IMAP provider so each computer has a fresh local cache.
