unified inbox

A fleet of inboxes that feels like one.

MasterInbox pulls every sending mailbox into a single surface. Triage, assign, and act on every reply from one command - so scaling from three inboxes to three hundred never turns into three hundred tabs.

What MasterInbox is

The reply layer for a solo operator at scale.

Part of the Sales Composer - the sending layer that comes with every seat. MasterInbox is where all of it converges: one surface for every inbox, every reply, every follow-up, no matter how many mailboxes are behind it.

One surface, every inbox

Connect every sending mailbox into a single unified view. No tab-hopping across dozens of accounts to find the reply that matters.

Intent-ranked triage

Replies surface ranked by intent - positive, objection, out-of-office, unsubscribe - so you act on the ones that convert first.

Rotation-aware

Pairs with pre-vetted inboxes and free email workers for automated sending and rotation - the plumbing pre-built, not months of setup.

Hands off to Reply Agent

Route any thread to Reply Agent to draft a response at your standard and book the meeting - review, then send.

One reputation per inbox

Tenant-isolated so a single burned mailbox never drags the fleet down. Health is visible per inbox, at a glance.

Driveable from a /command

Status, triage, and assignment run from the terminal like the rest of /legion - and Archon can drive it unattended.

The reply workflow

From forty inboxes to one next action.

01

Connect the fleet

Every sending mailbox flows into MasterInbox as one surface - however many are behind your campaigns.

02

Replies land ranked

Incoming replies are classified and ranked by intent, so the positive threads rise to the top instead of drowning.

03

Act or hand off

Reply yourself, or route the thread to Reply Agent to draft and book. You stay in control of what sends.

04

Health stays visible

Per-inbox reputation and deliverability are always on screen, so a weak mailbox gets pulled before it costs you.

A thousand soldiers. One general. You.

Run a hundred inboxes like one operator.

MasterInbox ships inside the Sales Composer with every founding seat - alongside the brain, the CLI, and a new system every month.
