Validate Pro performs e-mail address validation from a list or incorporated in your Web site without sending anything to the user. Validate Pro is both a sophisticated Windows desktop application as well as a validation engine that can be integrated into your Web site using the popular Microsoft ASP or Java JSP programming languages (Source code examples included). Validate Pro does more than basic e-mail syntax checking. It also does munge detection, TLD verification, DNS resolution (and caching), MX server querying, and can even be configured to perform filtering and classification based on an e-mail's keywords. Validate Pro does e-mail validation that is fast, flexible, and most importantly accurate.
