Simple email sender with JavaMail

Back to Menu

The JavaMail API provides a platform-independent and protocol-independent framework to build mail and messaging applications. The JavaMail API is available as an optional package for use with the Java SE platform and is also included in the Java EE platform.

This API gives Developers an easy, simplified and robust framework to write an Email Sender. It has very good integration with Spring Framework which has a ready to use Template to work with JavaMail. JavaMail with Spring is covered in a separate post which could be found under Spring Tab.

Following Example is self explanatory but if you have any question/query please leave a comment.

To run this program you will require javamail jar.

• You can download latest version of JavaMail (Version 1.5.1) from Java's standard website

import java.util.Properties;
import javax.mail.Message;
import javax.mail.Session;
