Your inbox, watched around the clock.

Yes — that's the point. Pro runs on a server or computer you control, so your mailbox tokens and AI keys never touch our systems. It installs with one Docker command on a small VM — a $5–15/month box is plenty — on always-on hardware you already own, like a Raspberry Pi, a NAS or a mini-PC, or with an installer for Windows, macOS or Linux if you would rather run it on your own machine.

Nothing is locked behind a receipt — the container image is public, so you can install it and run the 14-day trial before paying anything: docker pull ghcr.io/jjjjj-enterprises/email_sentinel. Buying sends you a license key by email, and that key is what keeps alerting on once the trial ends. Lose it and we can re-send it from your purchase address.

Yes — there are installers for Windows, macOS, and Linux, and the app starts when you sign in. The trade-off is honest: on your own machine it checks every minute while the machine is on, so it stops watching when the machine sleeps. Real-time push and genuine around-the-clock alerts need an always-on server.

Yes, and it's the cheapest way to run it around the clock — a few dollars a year in electricity instead of a monthly VM bill, on hardware you own. The container image is built for ARM as well as x86, so a Pi 4 or 5, a Docker-capable NAS, or a mini-PC all work. The one extra step is that a box at home has no public address, so the guide sets up a Cloudflare Tunnel — which needs no ports opened on your router. See the install guides for the full walkthrough.

Features are identical. The add-ins (Lite) can only scan while their pane is open — a hard limit Microsoft and Google place on add-ins. Pro runs continuously and pushes alerts in real time, even when your computer is off.

Whichever you want — Claude, ChatGPT, Gemini, Azure/Copilot, or any compatible model, set per mailbox. You bring your own API key, so AI usage is billed to you at cost.

Personal covers you, your household, and your work as a sole practitioner — a freelancer or independent consultant with no employees. Business is for use by or on behalf of a company with employees, or use for an employer. It is the same software either way; neither plan counts heads, so the price never changes as your household or your team grows.

The right to run emAIl Sentinel in your company, and your support questions answered ahead of the queue. The software is identical on every plan — there are no locked features and no seat counting. emAIl Sentinel is a small independent product, so no plan carries a guaranteed response time — Business simply goes first in the queue.

A lifetime license would mean supporting a company for as long as the product exists on a single payment, and that is not an open-ended commitment we will take on. The Personal lifetime license stays exactly as it is.

Yes, at no extra charge. One license covers everyone in your household — there is no per-person fee and no seat limit. Each person gets their own sign-in and sees only their own mailboxes, rules and alerts; you cannot read theirs and they cannot read yours. You can deliberately share an alert channel, an AI key, or a rule with each other, and take any of it back at any time.

Same software either way; it's just how you pay. The subscription ($15/mo or $150/yr) includes updates and support while active. The lifetime license (launch price $149 once, normally $199) never expires and includes all future updates — no recurring fees. Both are self-hosted on your own server.

The Pro software, updates, and support — you provide the server, AI key, and SMS account. If a subscription lapses, the app keeps running but stops sending alerts until you renew; a lifetime license never lapses.

Yes. Every install includes a 14-day full-feature trial with no key required. Buy a subscription or lifetime license whenever you're ready and paste the license key into your server.

No — by design. Alerts go to SMS, Teams, Google Chat, calendars, task lists, spreadsheets, notes, and webhooks, so an alert never gets buried in the very inbox you're watching.
