Why self-host email verification?

Third-party verification services see every email address you check. For competitive intelligence or privacy-sensitive industries, this is unacceptable. Self-hosted Reacher runs on your VPS -- email addresses never leave your infrastructure.

What does Tor proxy rotation provide?

10 Tor SOCKS5 instances on ports 9050-9059, each with independent circuits. Web scraping and OSINT requests are distributed across different exit nodes, preventing IP-based rate limiting and bans.

Why disable VPN for website crawling?

Tor exit nodes are widely blocked by CDNs and company firewalls (403 errors). Company website crawling works better from your VPS's direct IP. Re-enable Tor for email verification and OSINT where anonymity matters.

What are the VPS requirements?

Minimum: 2 CPU, 4GB RAM, 50GB SSD. Recommended for high-volume: 4 CPU, 8GB RAM. The deploy script handles installation of all dependencies: Python, Node.js, Tor, Reacher, and Supervisor.

VPS Infrastructure

Your data never leaves your infrastructure

Self-hosted verification, proxy rotation, dedicated workers

Run email verification and web scraping on your own VPS. Self-hosted Reacher for SMTP verification with zero third-party data exposure. 10 Tor SOCKS5 proxies for IP rotation. Supervisor-managed workers for always-on operation.

The Infrastructure Problem

Third-party email verification services see every email address you check -- competitor intelligence risk

API-based verification has per-check costs that explode at scale (100K+ emails = thousands of dollars)

Shared verification infrastructure means your verification requests compete with other customers

IP bans from web scraping affect all users on shared infrastructure, not just your activity

No control over verification timing, retry logic, or SMTP connection parameters

SaaS verification services impose rate limits that slow down large batch verifications

Dedicated, Private Infrastructure

Run everything on your own hardware. No shared resources. No third-party data exposure. Full control over configuration.

Self-Hosted Reacher

Open-source email verification server running on your VPS. SMTP checks without sending verification data to any third party.

10 Tor SOCKS5 Proxies

Ports 9050-9059 on dedicated VPS. Automatic rotation via vpn_proxy.py. Circuit rotation for IP diversity.

Supervisor Workers

Process manager keeps workers running 24/7. Automatic restart on crash. Log rotation and monitoring.

Zero Data Exposure

Email addresses, domains, and company data never leave your infrastructure. No third-party API calls for verification.

SQLite Cache

Local verification cache eliminates re-verification of known addresses. Results stored in database/email_verifier.db.

Configurable Workers

Adjust concurrent verification workers (default 50-200) based on VPS resources and SMTP response times.

Infrastructure Pipeline

Each stage processes data sequentially with full checkpoint/resume capability.

Step 1

VPS Provisioning

Deploy VPS with deploy scripts. Install Python, Node.js, Tor, Reacher, and Supervisor.

Step 2

Tor Setup

Configure 10 SOCKS5 instances on ports 9050-9059 with independent circuits.

Step 3

Reacher Deployment

Self-hosted Reacher on port 8080. Configure SMTP timeout, retry logic, and connection pooling.

Step 4

Worker Configuration

Supervisor manages verification workers. Auto-restart, log rotation, resource monitoring.

Step 5

VPN Toggle

VPN_ENABLED=false for company website crawling (Tor gets 403-blocked). Re-enable for verification.

Step 6

Verification Execution

Run email verifier against self-hosted Reacher. 8-check pipeline with local SMTP probing.

Step 7

Cache Management

Results cached in SQLite. Configurable cache TTL for re-verification of aged results.

Technical Workflow

# VPS deployment
bash deploy/deploy-platform.sh

# Email verification via self-hosted Reacher
python -m tools.email_verifier --input leads.csv --workers 50

# Verification REST API mode
python -m tools.email_verifier --api --port 8100

# VPN toggle for scraping (Tor gets 403-blocked on company sites)
# VPN_ENABLED=false  -> company website crawling
# VPN_ENABLED=true   -> email verification, OSINT

# Tor proxy rotation is automatic via utils/vpn_proxy.py
# Proxy ports: 9050-9059 on VPS ($VPN_TOR_HOST)
