Is email validation 100% reliable?

Email validation cannot be 100% reliable, because it relies on information provided by mail servers. There are some mail servers that will confirm the existence of any email address, including bad ones, and the Validator component has a feature called the “greenlist” that will inform you of these servers. This product is as accurate as possible without actually sending email messages to the recipients in your list.
