Short description
Main Direct is a B2B outreach supply engine. It turns a market description into audience filters, verified contact routes, liveness controls, dedicated deliverability infrastructure, first-touch routing and suppression systems.
Public modules
- Signal Atlas: audience research, evidence rules and targeting filters.
- Contact Supply: discovery, validation, provenance, normalization and export readiness.
- Deliverability Engine: dedicated domains, authentication, warm-up, pacing and reply routing.
- Self-supply playbook: public methodology artifact.
Best fit
Professional B2B teams that need an auditable supply route rather than a raw list or volume-only sending tool.
Not a fit
Consumer marketing, spam, deceptive identity, sensitive targeting, unlawful campaigns or buyers demanding guaranteed meetings, replies, revenue or inbox placement.
Required caveats
Verification is time-bound. Dedicated infrastructure reduces avoidable reputation damage but does not guarantee inbox placement or replies. The buyer remains responsible for lawful use.
