addresses, reducing the likelihood of errors and other issues down the line.

addresses can cause errors and other issues that can be frustrating for users
and difficult for developers to fix. Additionally, email validation can help
protect against spam and other malicious activity. By verifying that an email
address is real, you can reduce the risk of fake accounts and other types of
fraudulent activity on your website or application.
