The Importance of Email Validation
Email validation is crucial for several reasons:
Data Integrity: Validating email addresses ensures that only correctly formatted and legitimate emails are collected, improving the integrity of your data.
User Experience: By validating email addresses on the client-side, you can provide real-time feedback to users, alerting them to any errors and preventing submission of invalid emails.
Data Security: Validating email addresses helps protect your application and users from malicious inputs, such as email injections or spam.
4. Server-Side Validation -While client-side validation is essential for immediate feedback, it is crucial to perform server-side validation as well. Server-side validation acts as a final line of defense, ensuring that only valid email addresses are accepted and processed.
