Validating an email address is the process of verifying whether an email address is genuine and can receive emails. It plays a crucial role in preventing spam, ensuring the deliverability of emails, and maintaining the integrity of email communication.
There are multiple ways to check the validity of an email address. One common method is to use regular expressions to match the correct format of an email address. Another approach is to leverage email verification services that employ various techniques, including syntax checks, domain existence checks, and disposable email address detection, to determine the validity of an email address.
