Editions at a glance

Professional Edition

The Professional Edition of EmailVerify.NET is targeted at Microsoft .NET developers who want to integrate our email address validation technology into their own solutions, perhaps by validating user information on an ASP.NET website signup page or by adding an asynchronous email check to a data-entry, Windows Forms application. This edition is not suitable for processing large batches of data in parallel or for covering specific integration needs.

Enterprise Edition

The Enterprise Edition of EmailVerify.NET exposes all of the features of the Professional Edition and extends it with optimized algorithms that allow to validate huge sets of email addresses in parallel, possibly using different originating IP addresses and a proxy server for lowering the risk of being banned by the external mail exchangers. Furthermore, this edition can be easily integrated with Microsoft SQL Server 2008/2008R2 Integration Services (SSIS) and Windows PowerShell.

The End-User License Agreement (EULA) contains the terms and conditions that govern the use of EmailVerify.NET and has detailed information about the restrictions that each license imposes. Review the EULA.
