4 layers deep to find every email
Passive OSINT -> Direct Crawl -> Search Engines -> Google Playwright
Most email finders query a single database. LeadsLogix runs a 4-layer progressive pipeline that starts with zero-touch passive OSINT and escalates through direct crawling, multi-engine search, and Google Playwright -- plus an 8-pattern prediction engine that generates and validates likely email addresses.
Why Traditional Email Finders Fall Short
Progressive Discovery with Verification
Each layer only fires if previous layers didn't find enough emails. Combined with 8-pattern prediction for contacts without published addresses.
Layer 0: Passive OSINT
DNS records, DMARC policies, SPF includes, and Wayback Machine archives. Zero requests to the target domain. Completely passive.
Layer 1: Direct Crawl
Crawl contact, about, team, and privacy pages. Extract emails from HTML, mailto links, JSON-LD, and structured data.
Layer 2: Multi-Engine Search
SearXNG, Bing, Brave, DuckDuckGo, Mojeek, and Yahoo. Search for published email addresses associated with the domain.
Layer 3: Google Playwright
Last resort. Browser-automated Google search for email addresses when all other methods fail.
8-Pattern Prediction
first.last@, flast@, firstl@, first@, last@, first_last@, f.last@, first-last@. Generated for each contact and validated against MX records.
Integrated Verification
Every discovered and predicted email feeds directly into the 8-check verification pipeline. No unverified emails in output.
Email Discovery Pipeline
Each stage processes data sequentially with full checkpoint/resume capability.
Domain Validation
Verify domain exists, has MX records, and is not on the bad domain filter list.
Passive OSINT (Layer 0)
Query DNS, parse DMARC/SPF records, check Wayback Machine for archived email addresses.
Direct Crawl (Layer 1)
Crawl contact/about/team pages on the target domain. Extract emails from HTML, mailto, and structured data.
Multi-Engine Search (Layer 2)
Search 6 engines for domain-associated emails. Parse results, validate format, deduplicate.
Google Playwright (Layer 3)
Browser-automated Google search as last resort. Only fires if layers 0-2 returned insufficient results.
Pattern Prediction
For contacts with names but no emails: generate 8 email patterns, validate against SMTP, select best match.
Verification & Scoring
8-check verification pipeline. Score 0-100. Classify into TIER 1-4. Output only verified addresses.
