Frequently Asked Questions
Find answers to common questions about email verification.
What is the difference between email validation and email verification?
Email validation checks whether an email address is formatted correctly and safe to include in a list, while email verification confirms whether the mailbox actually exists and can receive emails on the server level.
Is email validation the same as email verification?
No. Email validation is the first step and focuses on format, syntax, and disposable emails. Email verification goes deeper by checking MX records, SMTP responses, and mailbox existence to reduce bounces.
Do I need both email validation and email verification?
Yes. Using both provides the best protection. Validation filters obvious bad inputs, while verification prevents hard bounces and protects sender reputation.
Does email validation improve deliverability?
Yes. Email validation improves deliverability by reducing hard bounces, preventing spam traps, and sending stronger trust signals to mailbox providers.
How often should email lists be validated or verified?
Email lists should be checked before every major campaign. High-volume senders typically validate monthly, while smaller or less active lists benefit from quarterly checks.
