Superkabe

Superkabe is an AI-powered cold email platform with native deliverability protection. Draft AI sequences, send across unlimited mailboxes (Gmail, Microsoft 365, or SMTP), validate every email, route leads by ESP, and let the protection layer auto-pause, reroute, and heal senders in real time. Every lead that enters Superkabe passes through a multi-stage pipeline before reaching your sender: Email Validation Syntax, MX records, disposable domains, catch-all detection + MillionVerifier API for risky leads. Invalid emails are blocked before they reach your sender. Health Gate (GREEN / YELLOW / RED) Every lead is classified by risk. GREEN routes normally, YELLOW distributes with per-mailbox caps, RED is blocked entirely. ESP-Aware Routing Each send is routed to the mailbox most likely to land in inbox for that recipient's ESP: Gmail, Outlook, Mimecast, or generic SMTP. Real-Time Monitoring Checks mailbox health every 60 seconds. Bounce rates, SMTP/IMAP connectivity, DNS authentication (SPF, DKIM, DMARC). Auto-Pause + Correlation Auto-pauses on threshold breach (3% bounce rate at 60+ sends, with a 5-bounce safety net). The correlation engine determines if the root cause is the mailbox, domain, or campaign. 5-Phase Healing Pipeline Pause → Quarantine (DNS check) → Restricted Send → Warm Recovery → Healthy. Fully automated with per-phase graduation criteria. AI-driven Claude / MCP integration, mailbox rotation, ESP-aware load balancing, Slack alerts, reports, and CSV export are included across all plans.
