Superkabe

Superkabe is an AI-powered cold email platform with native deliverability protection. Draft sequences with AI, send across unlimited mailboxes (Google Workspace, Microsoft 365, or any SMTP provider), validate every lead, and let the protection layer auto-pause, reroute, and heal your senders in real time. You can also run Superkabe in Protection Mode — connecting your Gmail, Microsoft 365, or SMTP mailboxes to send natively with the same safety layer.

Every lead that enters Superkabe flows through the same pipeline: email validation (syntax, MX, disposable, catch-all, plus MillionVerifier API on risky leads), the GREEN/YELLOW/RED health gate, ESP-aware mailbox routing, and continuous post-send monitoring with a 5-phase auto-healing recovery pipeline for any mailbox that degrades.

What Superkabe Does ? Email Validation — Syntax, MX records, disposable domains, catch-all detection + MillionVerifier API for risky leads ? Health Gate — Classifies leads as GREEN (safe), YELLOW (caution), or RED (block) based on validation score and domain health ? Lead Routing — Routes leads to campaigns by persona and minimum score, with wildcard catch-all rules and priority ordering ? Real-Time Monitoring — Checks mailbox health every 60 seconds: bounce rates, SMTP/IMAP connectivity, DNS authentication ? Auto-Pause — Pauses mailboxes and domains when bounce thresholds are breached, with correlation engine to detect root cause ? 5-Phase Healing — Paused ? Quarantine ? Restricted Send ? Warm Recovery ? Healthy. Fully automated with graduation criteria per phase ? Mailbox Rotation — When a mailbox is paused, a healthy standby mailbox is automatically swapped in to keep campaigns sending ? Native sending — Gmail, Microsoft 365, or SMTP mailboxes connected via OAuth or encrypted credentials
