Release Notes
Every improvement, feature, and fix shipped to Superkabe. Stay up to date with what is new in the platform.
Lead Control Plane and ESP-Aware Routing
Superkabe becomes the primary lead entry point. Upload CSVs directly, validate every email, classify recipients by ESP, and route to the best-performing mailboxes automatically.
- Lead Control Plane — CSV upload with validation, ESP classification, and campaign routing
- ESP-Aware Mailbox Scoring — route leads to mailboxes with the lowest bounce rate for the recipient ESP
- SendEvent + ReplyEvent tracking — every email sent and replied is recorded per mailbox per ESP
- ESP Performance Matrix dashboard — per-mailbox bounce rates broken down by Gmail, Microsoft, Yahoo
- Validation credits with monthly tier limits and enforcement
- Cross-batch duplicate detection — prevents double-processing across uploads
- Rejection reason tracking — disposable, no MX, syntax, SMTP fail, catch-all breakdown
- Analytics deep-dive — invalid rate by source, rejection reasons chart, 30-day trend
Hybrid Email Validation and Load Balancing
This release introduces a hybrid email validation layer that checks every incoming lead before it reaches your sending platform. We also added multi-select filters across all dashboard pages and completely redesigned the load balancing system.
- Hybrid email validation layer (syntax, MX, disposable, catch-all + MillionVerifier API)
- Real-time validation activity feed on leads page
- Multi-select filters across all dashboard pages
- Confirmation modals for pause/resume actions
- Load balancing redesign with effective load metric
5-Phase Healing Pipeline and State Machine Migration
The biggest architectural change since launch. All status transitions now go through a centralized state machine, and the healing pipeline graduates mailboxes through 5 controlled phases instead of binary pause/resume.
- 5-phase healing pipeline (paused → quarantine → restricted → warm → healthy)
- State machine migration — single authority for all status changes
- Mailbox rotation with standby mailboxes
- Correlation engine for cross-entity failure detection
Multi-Platform Support and Risk-Aware Routing
Superkabe now works with Smartlead, Instantly, and EmailBison simultaneously. The platform adapter pattern means adding a new sender takes implementing 4 methods. Lead routing is now risk-aware with GREEN/YELLOW/RED classification.
- Multi-platform support (Smartlead + Instantly + EmailBison)
- Platform adapter pattern
- Risk-aware lead routing (GREEN/YELLOW/RED)
- Slack real-time alerts
Infrastructure Assessment and DNS Health
New onboarding flow that assesses your infrastructure health before you start sending. DNS checks verify SPF, DKIM, and DMARC configuration. The analytics dashboard shows engagement trends over time.
- Infrastructure assessment on onboarding
- DNS health checks (SPF, DKIM, DMARC)
- Bounce classification (hard/soft/transient)
- Analytics dashboard
Automated Bounce Management and Campaign Protection
The core protection loop is now automated. Mailboxes that exceed bounce thresholds are auto-paused, and campaigns that lose all healthy mailboxes are stopped automatically.
- Automated bounce management
- Campaign auto-pause when all mailboxes unhealthy

The first version of Superkabe. Connects to Smartlead, syncs your campaigns, mailboxes, and leads, and provides real-time bounce monitoring with manual intervention tools.
