Verification infrastructure for the whole engine Verify the emails
every other tool can't.
Standard validators stop at SMTP and mark catch-all domains as risky. Scrubby goes further, confirms whether a catch-all address actually lands, and returns a definitive answer. Every address the engine contacts passes through it first.

How it works
Scrubby in three steps.
- 01
Upload or connect
Bulk CSV, API, or a direct CRM connection. Scrubby runs standard SMTP checks first and separates the catch-all set.
- 02
Verify the catch-all
Catch-all addresses are tested against live mailbox behaviour on Vendisys infrastructure, never your domains, until they resolve to deliverable or invalid.
- 03
Return a verdict
Every address comes back as deliverable, risky or invalid with a reason code, ready for Inboxy, EMY and KALI to use.
Capabilities
Everything Scrubby does.
Catch-all resolution
The only validator that returns a definitive result for catch-all domains instead of a shrug.
Zero-bounce guarantee
Testing happens on Vendisys infrastructure, so your sending reputation is never used to verify a list.
Bulk and API
Upload lists of any size or verify in real time from your forms and enrichment waterfalls.
CRM cleaning
Connect HubSpot or Salesforce and keep records clean continuously, not once a year.
Risk scoring
Role accounts, disposable domains, spam traps and blacklisted domains flagged with reason codes.
Engine integration
CAM signals and every outreach list pass through Scrubby before Inboxy sends a single email.
Connects to HubSpot and Salesforce. Ships with an MCP server. Like every Vendisys product, Scrubby writes contacts, activities and outcomes to your CRM, and exposes its capabilities to AI agents through MCP.
Where it sits in the engine
Scrubby is one part of the complete outbound engine.
Scrubby is infrastructure. Every agent on the platform depends on it, and nothing is sent until it has done its job.
What is a catch-all domain?
A domain configured to accept mail for any address, so SMTP checks cannot tell a real mailbox from a fake one. Most validators mark these as risky and most teams discard them, losing up to half their market.
How does Scrubby verify catch-all without bouncing?
By testing against live mailbox behaviour on infrastructure Vendisys controls. Your domains and mailboxes are never involved.
How long does a list take?
Standard checks are instant. Catch-all resolution typically completes within 24 to 72 hours depending on the domains involved.
Does it integrate with my stack?
Clay, HubSpot, Salesforce, Instantly, Smartlead, Zapier and a full REST API.
