Frequently asked questions
What is email verification?
Email verification is the process of checking whether an email address is valid, active, and safe to send to without actually delivering a message to the inbox.
Why do I need to clean my email list?
Cleaning your email list removes invalid addresses, spam traps, and inactive users, which protects your sender reputation and improves overall campaign deliverability.
How often should I verify my mailing list?
It is recommended to verify your email list every three to six months because email addresses naturally decay as people change jobs or abandon old accounts.
