Verification Engine
Six Layers of Email Validation
Every email passes through our comprehensive pipeline before you send a single campaign.
Syntax & Format
RFC 5321/5322 compliance checks catch typos, missing @ symbols, and malformed addresses.
DNS & MX Records
Confirms the domain exists and has properly configured mail exchange servers.
Disposable Detection
Flags 1,000+ temporary email providers like Guerrilla Mail, Temp Mail, and Mailinator.
Role-Based Detection
Identifies generic addresses like admin@, support@, and info@ that cause high bounce rates.
REST API Access
Integrate directly into your stack with our simple POST API and webhook callbacks.
Detailed Reports
Color-coded results with downloadable CSV exports. Per-email pass/fail reason included.
Simple Workflow
