Why is self-hosted verification important for B2B Companies?

Self-hosted verification means your B2B Companies email lists are never transmitted to third-party cloud servers. This is critical for B2B Companies organizations that handle sensitive contact data, operate under compliance requirements, or simply want to maintain data sovereignty over their prospect lists.

What does the 4-tier scoring mean for B2B Companies campaigns?

TIER_1 (80+): Safe to send — high-confidence B2B Companies emails. TIER_2 (50-79): Likely good — include in campaigns with monitoring. TIER_3 (30-49): Review required — may be valid but has risk factors. SKIP (<30): Do not send — high bounce probability. Most B2B Companies cold outreach campaigns should only target TIER_1 and TIER_2.

How fast can LeadsLogix verify B2B Companies email lists?

With 200 concurrent workers, the platform can verify thousands of B2B Companies emails per hour. Previously verified emails return from cache in under 0.5 seconds. Circuit breakers automatically protect against aggressive SMTP servers that could slow down verification.

What causes B2B Companies emails to score low?

Common reasons for low scores on B2B Companies emails include: failed SMTP handshake (mailbox doesn't exist), domain has no MX records, email is role-based (info@, admin@), domain is catch-all (accepts everything), disposable email service, or missing DKIM/SPF/DMARC authentication records.

Can I verify B2B Companies emails in real-time via API?

Yes. The verification engine runs in REST API mode on port 8100, accepting single email or batch verification requests. This enables real-time verification of B2B Companies contacts at point of capture — web forms, integrations, and CRM workflows.
