Discover. Predict. Verify.
From zero emails to verified inboxes
Three interconnected systems work together: a 4-layer discovery pipeline finds published emails, an 8-pattern prediction engine generates likely addresses, and an 8-check verification pipeline scores every email 0-100.
4-Layer Discovery Pipeline
Passive OSINT
DNS records, DMARC policies, Wayback Machine archives. Zero requests to the target domain.
Direct Website Crawl
Crawl contact, about, team, and privacy pages. Extract emails from HTML, mailto links, and structured data.
Multi-Engine Search
SearXNG, Bing, Brave, and DuckDuckGo. Search for published email addresses associated with the domain.
Google Playwright
Last resort. Browser-automated Google search for email addresses when passive and direct methods fail.
8-Check Verification Pipeline
| Check | Description | Weight |
|---|---|---|
| Syntax Validation | RFC 5322 compliance check | +5 |
| DNS/MX Lookup | Verify domain has mail exchange records | +20 |
| SMTP Handshake | Connect to mail server, verify mailbox exists | +40 |
| Catch-All Detection | Identify domains that accept all addresses | +5 |
| Disposable Domain | Flag temporary/throwaway email services | +5 |
| Role-Based Filter | Detect info@, admin@, support@ addresses | +5 |
| DKIM/SPF/DMARC | Verify authentication records exist | +15 |
| Reacher Fallback | Secondary verification via self-hosted Reacher | +10 |
4-Tier Confidence Scoring
TIER 1: SEND
80-100Safe to send. Verified mailbox, valid domain, strong authentication.
TIER 2: LIKELY GOOD
50-79Likely valid. Partial verification. May be catch-all domain.
TIER 3: REVIEW
30-49Needs review. Inconclusive verification or weak signals.
TIER 4: SKIP
0-29Do not send. Invalid, disposable, or bouncing address.
