# MailSubsystem Managed Service

Headline:

> Inbox protection your family can rely on.

Tagline:

> Your mom and dad shouldn't be scammed.

MailSubsystem watches the inbox for the patterns that get people in trouble: payment pressure, sender impersonation, suspicious links, and unusual requests. Risky messages are held for human review before anything moves. The managed service runs the Core email intelligence engine for families, caregivers, and small teams that need phishing and fraud defense without operating a Rust daemon, PostgreSQL, or a local model server.

## What It Does

Scams imitate people, exploit urgency, and borrow brand language. Spam filters were not designed to catch every targeted family or small-team fraud pattern.

The managed service focuses on:

- sender behavior, payment pressure, credential requests, link mismatches, and impersonation patterns
- clear review states for risky messages before filing or action
- sender, thread, folder, and semantic memory from the Core
- caregiver-aware visibility without turning every inbox into a shared mailbox
- account isolation, audit trails, secret handling, support workflows, and onboarding

## Platform Model

The intelligence comes from the open-source Core so users can audit how decisions are made. The managed service is the operational shell around it:

- tenant and account boundaries
- identity
- authorization and RBAC
- audit infrastructure
- billing
- support workflows
- onboarding

## Signup

The current browser signup form stores early-interest entries in browser `localStorage` until a backend or contact endpoint is added. The call to action is release notes and early access for the managed service.
