PowerTCP Email Validation for .NET is a robust and flexible component that allows you to add email address verification to .NET and ASP.NET applications. Developers are able to configure this component to achieve a custom balance of speed and validation strictness. Setting the maximum validation level determines whether the component simply checks address syntax, performs an actual SMTP recipient check, or five levels in-between. Furthermore, validation may be performed synchronously or asynchronously, depending on project implementation requirements.
