Everything you need to know about email verification
Email bounce verification checks if an email address is valid and can receive emails. It helps you clean your email lists before sending campaigns, reducing bounce rates and improving deliverability.
We perform multiple validation checks: format validation (syntax), domain existence check (DNS lookup), MX record verification (mail server check), and disposable email detection. This multi-layer approach ensures accurate results.
