Stealth inbox infrastructure you run from a /command.
Order domains, spin up mailboxes, and send cold email that inbox providers cannot pattern-match - stealth domains and stealth personas over isolated, fully-authenticated infrastructure, all driveable by an agent or CLI.
Inboxes that stay undetected.
Google and Microsoft now fingerprint the repeating patterns of cold-outbound setups and flag them. Mail Legion breaks the fingerprint - so your sending footprint never looks like a bulk cold-email fleet.
Stealth domains
Every subdomain spawns with its own real landing page, each with slightly varied copy - so the pattern across your domains is unguessable.
Randomized buys
Purchases are spread over 48 hours across different buckets and randomized - your buying footprint stops looking bulk.
Non-randomness flag
The system flags when your purchases are not random enough and nudges you to diversify before a pattern forms.
Stealth personas
Almost every domain gets its own sending persona - a unique AI-generated image, full name, signature, and title. No templated fleet to flag.
One reputation each
Tenant-isolated infra - dedicated inboxes, no shared IPs - so one burned domain never collapses the rest.
Agent-native
An MCP server plus the Axi CLI drive the whole stack from a /command - not a dashboard you click through.
Every domain is its own person.
A fleet board, not a spreadsheet. Each stealth domain carries a unique persona - image, name, title - over its own isolated mailboxes and reputation, with warmup ramping automatically. The randomness check confirms the whole buy pattern stays unguessable.
Licensed, isolated, and fully authenticated.
Enterprise sending infrastructure, provisioned for you - no shared IPs, full DNS auth, automated warmup, and live in 48 hours with zero technical setup on your side.
* Platform-published figures, pending confirmation before launch. Retail pricing set at launch.
The only sending infra that is agent-native.
Order domains
A single command schedules a randomized, 48-hour bucketed buy - the footprint an inbox provider cannot pattern-match.
Provision mailboxes
Isolated inboxes come up with full DNS auth and automated warmup - no manual DNS, no plumbing.
Assign personas
Every domain gets a unique stealth persona - image, name, signature, title - so nothing reads as a templated fleet.
Check randomness, then send
The randomness check confirms your footprint stays unguessable, then you send through your sequencer of choice.
The rest of the stack.
Send at scale, and stay invisible.
