What is MailboxValidator?

MailboxValidator is a tool designed to verify email addresses for companies that need to send email for verification reasons. It lists thousands of different domains and looks up which ones are valid and which ones are not. Companies can also input their own domain, and will be given the percentage of email addresses that _might_ possibly work, although this can vary depending on how many customers are actually using mailbox validators instead of traditional mail boxes.
