How Does Recipient Verification Work?
Recipient verification involves using various tools and techniques to confirm that the email addresses on your list are valid and active. Typically, this process includes syntax checks, domain validation, and mailbox verification. Syntax checks ensure the email addresses are formatted correctly. Domain validation confirms that the email domain exists and is functioning. Mailbox verification checks if the specific mailbox is active and can receive emails.
