Stop validating emails with regex: here's what to do instead

The article highlights that commonly used regular expressions for email validation are fundamentally flawed because they only check the format without verifying if the email actually exists or is in use. This oversight can lead to accepting invalid or disposable email addresses, undermining the reliability of your signup process. Instead of relying on regex, the author suggests implementing more robust checks, such as sending a confirmation email, to ensure the provided email is both valid and active, thus improving the overall integrity of user data.
