High Performance

With GemBox.Email you will experience high performance composing, receiving, sending and other email processing related tasks.

Simple and Intuitive API

GemBox.Email is designed and developed to conform to Microsoft standards and best practices for developing .NET libraries.

Since MIME is quite a complex standard, some components have a very complicated API as a result. On the other hand, APIs like System.Net.Mail have a very simple yet limited API. GemBox.Email provides both. The top layer API is simple and intuitive, while the lower one exposes the MIME model, which can be used for advanced and more complex operations. They are synchronized with each other, so you can mix them in your code, without worrying if all the settings will be applied.
