📧 Advanced Email Checker & Verifier (Rust-Powered)

Verify the existence of any email address in real-time without ever sending a single message. This high-performance Apify Actor uses a specialized Rust engine to perform deep SMTP handshakes, MX record validation, and provider-specific checks (Gmail, Yahoo, Outlook) with extreme speed and accuracy.

🚀 Key Features

• No Emails Sent: Validates addresses using SMTP handshakes—completely invisible to the recipient.
• High Performance: Built on a multi-threaded Rust core with parallel processing for massive batch lists.
• Smart Provider Support: Specialized logic for Gmail, Yahoo, and Outlook, including headless browser verification for difficult providers.
• Deep Validation: Checks syntax, MX records, SMTP deliverability, and catch-all status.
• Security & Privacy: Support for SOCKS5 proxies to ensure high deliverability and avoid IP blocking.
• Enrichment: Optional Gravatar image detection and HaveIBeenPwned breach checks.

🛠️ How to Use

1. Input Emails: Provide a single email or a list of emails in the input JSON.
2. Configure (Optional): Set your from_email and hello_name (recommended to use your own domain for better results).
3. Run: Start the Actor. It will process your list in parallel.
4. Get Results: Download your verified list in JSON, CSV, or Excel format from the Apify Dataset.
