Verify address
What is it?
Email verification combines syntax checks with DNS and provider signals to estimate whether an address can receive mail.
Why is it important?
Invalid and disposable addresses increase bounce rates and can harm sender reputation.
How do you improve it?
Correct syntax errors, confirm the domain publishes MX records, and use confirmed opt-in before sending campaigns.
