Mail Engine

A private AI coworker for your email · Arborice

Your inbox runs your day, and most of it is the same work over and over. The Mail Engine is a digital coworker that reads every message, sorts and prioritizes it, drafts replies from your own knowledge, follows up on what's waiting, and reports on it all. It runs quietly in the background on your own computers. You approve everything that matters.

It is not a chatbot and not an auto-responder. It analyzes, understands, proposes, and learns from how you actually work, while you keep the final say on every reply that leaves your inbox.

What it does

One assistant, the whole email workflow

Every message runs through the same flow: read, classify, check knowledge, draft, and wait for your approval before anything is sent.

Reads & sorts

Monitors your inboxes, classifies every message by intent and priority, and quarantines spam to a recoverable log. Nothing is ever deleted for good.

Drafts replies

Writes a proposed reply for each message, grounded in your documents and past answers, in your tone, with an explanation of why it proposed it.

Follows up

Tracks threads waiting on a reply, yours or theirs, and drafts the nudge so nothing slips through the cracks.

Routes & schedules

Forwards messages to the right person or department, and turns meetings and deadlines into proposed calendar events for you to confirm.

Keeps it clean

Tags and archives resolved threads, groups by topic, and bulk-unsubscribes from newsletters and promotions, all reversible.

Reports

Daily, weekly, and monthly reports on volume handled, hours saved, AI accuracy, and cost, plus live dashboards.

How you adopt it

Four levels. The AI earns autonomy as trust builds.

You start where the assistant cannot get it wrong, it only reads and sorts, and turn on more autonomy as the results earn your confidence. All four run on the same install.

Level 1

Sort

Connects your email, classifies every message by intent and priority, and sends spam to recoverable quarantine. Your inbox arrives sorted every morning.

The AI only reads. Zero automatic actions.

Level 2

Respond

Adds the knowledge base and history import. The AI drafts every reply with its context, tone, and reasoning. Every action is audited.

The AI proposes; you approve one by one.

Level 3

Automate

Automatic replies to recurring questions, routing to the right area, follow-ups, inbox cleanup, and capturing meetings into the calendar.

The AI acts on its own, only where you authorize it.

Level 4

Govern

Workflows by request type, continuous learning from your corrections, executive dashboards, analytics, and automatic reports.

You administer your own AI, editing rules without depending on us.

Why it's different

Built to be trusted, not just clever

Private & local

It runs on your own computers. Your information, knowledge, and history stay inside your company. No cloud for sensitive data, and no recurring cloud costs.

You approve everything

No reply to a non-routine request is ever sent without your click. Every AI draft is clearly flagged, easy to edit, and fully logged.

It learns from you

Every reply you approve, edit, or reject makes it better. Your operational knowledge becomes a reusable asset instead of living in people's heads.

Measured, not guessed

Accuracy, hours saved, and cost are tracked in real time, so you always know exactly what it's doing for you.
