Syntax Checking: This involves verifying the structure of the email address to ensure it follows the correct pattern (e.g., local@domain.com). Domain Verification: Ensures that the email domain exists and is capable of receiving emails. Mailbox Verification: Confirms that the specific mailbox exists and is not full or disabled.
