Superkabe

Every cold email tool sends until something breaks. Then you find out weeks later — reply rates crater, your domain hits a blacklist, and you're shopping for new inboxes at 2 AM.

Superkabe is different. We built the industry's first 5-phase auto-healing pipeline — an active rehabilitation system that detects compromised mailboxes the moment they degrade, quarantines them before damage spreads, and gradually rebuilds their reputation back to full health.

How healing works

Paused → Quarantine → Restricted Send → Warm Recovery → Healthy

No binary on/off. Each phase has graduation criteria: clean send counts, bounce and complaint gates, live DNS health, and time-in-phase floors. A mailbox doesn't just "come back online" — it earns its way back.

Resilience Score: a credit score for your sender reputation

Every mailbox carries a 0–100 Resilience Score that adapts healing speed to real sender history. Strong score? Faster recovery. Weak score? Slower, more careful rehab. Relapse? Automatic step-down with 2x cooldown. Repeat offender? Escalated for manual review before it can hurt you again.

Fail-closed by design

We never graduate a mailbox out of quarantine without live SPF, DKIM, DMARC, and blacklist verification. Below a 25/100 infrastructure score, even operator overrides are blocked — because some domain damage can't be undone, and we'd rather slow you down than let you torch an asset.

Origin-aware recovery

New or burned domain being rebuilt? Rehab mode. Healthy domain that recently degraded? Recovery mode. The system knows the difference and treats them accordingly.

Auto-resume, zero babysitting

When a mailbox graduates back to healthy, paused campaigns waiting on it resume automatically. You get clean operator alerts at every milestone — paused, quarantined, recovered, or escalated — with 15-minute coalescing so storms don't spam your inbox.

Instantly and Smartlead let your domains die quietly. Superkabe fights to bring them back.

Send confidently. Heal automatically.
