What data formats can I import?

CSV and Excel (.xlsx) files are supported. The platform auto-detects column headers for company name, domain, email, phone, and address fields. You can also input individual companies by name or domain.

How does the 5-layer scraping hierarchy work?

Each company website is processed through up to 5 layers: Static HTML extraction, JS data parsing (__NEXT_DATA__, API endpoints), Structural page discovery (/team, /about), Semantic contact extraction, and Browser rendering (Playwright). Each layer only runs if the previous one produced insufficient data.

What do the verification tiers mean?

TIER_1_SEND (score 80+): safe to send. TIER_2_LIKELY_GOOD (50-79): probably valid. TIER_3_REVIEW (30-49): manual review recommended. SKIP (below 30): do not send. Scores are based on 8 checks including SMTP handshake, DNS/MX, catch-all detection, and authentication records.

Can I resume a failed pipeline?

Yes. All pipelines support checkpoint/resume. Use the --resume flag to continue from where processing stopped. The system uses SQLite WAL checkpoints to track progress per company.
