Done-for-you email infrastructure for lead gen teams —  without burning domains.

We automate subdomain creation, DNS configuration, and inbox infrastructure at scale—so you can send high volumes, protect deliverability, and save significant time and costs.

Our Setup Process

1. Single Domain Strategy

feature1

You only need one main domain (example: Leadgeninsider.co). We automate everything else.

Instead of buying 500 separate domains, we generate hundreds of subdomains such as:

  • best.leadgeninsider.co
  • try.leadgeninsider.co
  • pro.leadgeninsider.co
  • see.leadgeninsider.co

Each subdomain functions as an independent sending entity, protecting deliverability.

2. Automated Subdomain Creation

feature2

Automated Subdomain Scaling We instantly deploy 500+ standardized subdomains via precision scripts. By eliminating manual DNS configuration, we ensure an error-free, high-deliverability foundation built for infinite scale.

  • Fast deployment
  • No missed records
  • Fully standardized setup

3. Safe Inbox Scaling Strategy

feature3

We assign 3 inboxes per subdomain to balance volume and inbox safety.

  • name.last@Leadgeninsider.co
  • name@Leadgeninsider.co
  • lastname@Leadgeninsider.co

This keeps inbox behavior natural and reduces spam signals.

4. Scalable, Replaceable, Safe

feature4

If inbox health drops, we spin up new subdomains and inboxes using the same automation—without rebuilding your entire system.

  • Modular Recovery
  • Zero-Downtime Scaling
  • Reputation Firewalls
  • Predictable ROI

Result: lower costs, faster recovery, predictable scale.
