What happens in those 3 seconds
Every email runs through our multi-stage pipeline. Here are the key stages:
Syntax Validation
Checks format compliance with RFC 5322 standards.
DNS & MX Lookup
Verifies the domain exists and has valid mail exchange records.
SMTP Handshake
Connects to the mail server to confirm the mailbox exists.
Catch-All Detection
Identifies domains that accept all emails regardless of validity.
Disposable Email Check
Flags temporary/throwaway email addresses (Mailinator, Guerrilla, etc.).
Role Account Detection
Detects generic addresses like info@, support@, sales@.
Spam Trap Detection
Identifies known spam trap addresses that could destroy deliverability.
Typo Correction
Auto-fixes common typos (gmial.com → gmail.com, yaho.com → yahoo.com).
