Check If Email Exists
This project is an email verification tool that checks if an email address exists and can receive messages without sending an actual email. It provides these capabilities through a programmatic HTTP API and a local command line interface.
The system distinguishes itself by combining SMTP handshake verification and DNS record resolution with a risk analysis tool that detects disposable addresses, role-based accounts, and catch-all domains. It also includes a metadata aggregator to retrieve public profile information and imagery associated with a specific email address.
The broader capability surface covers email deliverability validation, risk assessment to prevent fraudulent signups, and SMTP connectivity testing.
The backend service can be deployed as a networked service using a containerized deployment model.
