Email validation is the process of verifying whether an email address is valid and active. This can be done through a variety of methods, including:
- Syntax checking: This involves checking the email address for proper formatting, such as the presence of an “@” symbol and a domain name.
- DNS lookup: This involves checking the Domain Name System (DNS) to see if the domain name associated with the email address exists.
- SMTP check: This involves sending an email to the address and checking if it bounces back.
Email validation is important for a number of reasons. First, it can help to prevent spam and phishing attacks. Second, it can help to ensure that emails are delivered to the intended recipient. Third, it can help to improve the accuracy of email lists.
