Legion members get exclusive access to Mail Legion's private managed email infrastructure.
Mail Legion is a separate LeadGrow business: licensed, isolated cold-email sending infrastructure with a stealth layer that keeps your domains and personas from reading as a bulk cold-outbound fleet.
Licensed, isolated infrastructure, plus a stealth layer.
Mail Legion runs on licensed, isolated cold-email infrastructure, wrapped in a proprietary stealth layer built to defeat inbox-provider pattern recognition.
Isolated infra
Dedicated inboxes, no shared IPs, one reputation per customer, so one burned domain never collapses the rest. Full SPF, DKIM, DMARC set automatically.
Stealth domains
Each subdomain gets a real landing page with distinct copy, helping domains retain separate identities.
Stealth personas
Almost every domain gets its own sending persona: a unique AI-generated image, full name, signature, and title, so personas do not read as a templated fleet.
Sequencer integrations: Instantly, Smartlead, Apollo.
An agent-native control layer is on Mail Legion's roadmap; it is not presented as a shipped interface.
This is a membership benefit, not a public product.
Membership is the path in. Mail Legion is not sold as a separate self-serve product on this page.
Send at scale, and stay invisible.
