How Triple-Layer Verification Works

01
🔤

Syntax Check

Validates email format, special characters, and structural integrity against RFC 5322 standards.

02
🌐

Domain & DNS

Verifies MX records exist, domain is active, and not a known disposable or spam domain.

03
📡

SMTP Handshake

Connects to the mail server to confirm the mailbox exists without sending an actual email.
