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.
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 FastReply
Route any thread to FastReply to draft a response at your standard and flag it meeting-ready - 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 wire straight into a GTM Studio sheet column.
Forty inboxes, ranked into one queue.
Every mailbox on the left, health at a glance. Every reply on the right, ranked by intent - so the positive threads sit at the top instead of buried across a hundred tabs.
From forty inboxes to one next action.
Connect the fleet
Every sending mailbox flows into MasterInbox as one surface - however many are behind your campaigns.
Replies land ranked
Incoming replies are classified and ranked by intent, so the positive threads rise to the top instead of drowning.
Act or hand off
Reply yourself, or route the thread to FastReply to draft and flag the meeting. You stay in control of what sends.
Health stays visible
Per-inbox reputation and deliverability are always on screen, so a weak mailbox gets pulled before it costs you.
Works with the whole stack.
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.
