1. Syntax Check
Verifies the email follows proper format rules (RFC 5322).
2. Domain Check
Confirms the domain has valid MX records that can receive mail.
3. SMTP Verification
Pings the mail server to confirm the mailbox exists without sending a message.
Why Validate Before Sending?
- ✔ High bounce rates damage your sender reputation permanently
- ✔ Email providers may block your entire domain after repeated bounces
- ✔ You waste time writing personalized emails to dead addresses
- ✔ Catch-all domains can skew your open rate metrics
- ✔ Disposable/abuse emails are often spam traps
