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.
