This package can get the results of email validation in JSON format.

It provides classes that take the results of a given email validation class and encode them as a JSON string so they can be returned as responses of applications that need to process the results in that format on the client side like AJAX applications and API based applications such as those that run on mobile devices.

The package provides wrapper classes for void and complex results and responses.
