🔍 How the 6-Layer Verification Engine Works

Each email address is processed through a series of deep validation checks:

1. Syntax Validation: Checks if the email follows standard formatting rules (RFC compliant).
2. Domain & MX Checking: Confirms if the domain is active and has valid Mail Exchanger (MX) records to receive mail.
3. Office 365 Directory Handshake: Special protocol check to validate Microsoft/O365 mailboxes with 100% accuracy.
4. SMTP Connectivity Check: Establishes a temporary connection to the recipient's mail server to check mailbox existence without sending a real email.
5. Disposable & Burner Filter: Flags temporary burner accounts (e.g. Mailinator, TempMail) to prevent spam signups.
6. Role Account & Free Email Detection: Detects functional group emails (e.g., info@, support@) and free providers (Gmail, Yahoo).

📥 Input Configuration

Input is extremely simple. You only need to configure:

• Emails Input List (leads): Paste your list of emails (one address per line).
• Concurrency Limit (concurrency_limit): Maximum number of parallel workers (default is 5).

{
  "leads": "hello@stripe.com\ncontact@shopify.com",
  "concurrency_limit": 5
}
