Featuring multi-threaded processing, intelligent mail server detection, and comprehensive proxy support, Rapid delivers fast and accurate email account validation at scale.

Key Features
Multi-Protocol Support
Currently supports IMAP protocol with POP3 planned, automatic mail server detection via API and DNS fallback
High-Performance Threading
Configurable multi-threaded processing (1-5000 threads) with real-time performance metrics and progress tracking
Advanced Search Capabilities
Search validated accounts for specific content with multiple query types (from, subject, body, date ranges)
Intelligent Proxy Management
Multiple rotation strategies (round-robin, random, consecutive) with automatic refresh and protocol override options
Domain Analysis
Real-time domain distribution analysis with filtering, search, and visualization of email provider statistics
Advanced Credential Filtering
Password complexity scoring (0-10), special character requirements, length constraints, and domain-based filtering
Smart Retry Logic
Configurable retry attempts (0-10) with delays (0-1000ms), intelligent error handling for temporary failures
Real-Time Statistics
Live monitoring of success rates, processing speed (CPM), detailed error categorization, and domain distribution
Supported Input Format
Rapid accepts email credentials in the following format:
- Email:Password:
[email protected]:password123
(one per line)
The system automatically validates email formats and counts valid entries.
Result Categories
Rapid categorizes results with detailed status information:
- Success: Valid credentials with successful authentication
- Invalid Credentials: Incorrect username/password combination
- Server Not Found: Unable to locate mail server for domain
- Connection Failed: Network connection errors
- Timeout: Operation exceeded configured timeout
- TLS Error: SSL/TLS handshake or certificate issues
- Protocol Error: Server protocol violations or incompatibilities
- Account Locked: Account security lockout
- Auth Method Not Supported: Server doesn't support required authentication
- Proxy Error: Proxy-related connection failures
- Rate Limited: Server rate limiting detected
- Cancelled: Operation cancelled by user
- Unknown: Unclassified errors
All results include detailed metadata: protocol used, duration, retry count, proxy information, and server details.
