Today we will look into JavaMail Example to send email in java programs. Sending emails is one of the common tasks in real life applications and that’s why Java provides robust JavaMail API that we can use to send emails using SMTP server. JavaMail API supports both TLS and SSL authentication for sending emails.

JavaMail Example
Today we will learn how to use JavaMail API to send emails using SMTP server with no authentication, TLS and SSL authentication and how to send attachments and attach and use images in the email body. For TLS and SSL authentication, I am using GMail SMTP server because it supports both of them.
JavaMail API is not part of standard JDK, so you will have to download it from it’s official website i.e JavaMail Home Page. Download the latest version of the JavaMail reference implementation and include it in your project build path. The jar file name will be javax.mail.jar.
If you are using Maven based project, just add below dependency in your project.
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.5.5</version>
</dependency>
Java Program to send email contains following steps:
- Creating
javax.mail.Sessionobject - Creating
javax.mail.internet.MimeMessageobject, we have to set different properties in this object such as recipient email address, Email Subject, Reply-To email, email body, attachments etc. - Using
javax.mail.Transportto send the email message.
The logic to create session differs based on the type of SMTP server, for example if SMTP server doesn’t require any authentication we can create the Session object with some simple properties whereas if it requires TLS or SSL authentication, then logic to create will differ.
So I will create a utility class with some utility methods to send emails and then I will use this utility method with different SMTP servers.
JavaMail Example Program
Our EmailUtil class that has a single method to send email looks like below, it requires javax.mail.Session and some other required fields as arguments. To keep it simple, some of the arguments are hard coded but you can extend this method to pass them or read it from some config files.
package com.journaldev.mail;
import java.io.UnsupportedEncodingException;
import java.util.Date;
import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class EmailUtil {
/**
* Utility method to send simple HTML email
* @param session
* @param toEmail
* @param subject
* @param body
*/
public static void sendEmail(Session session, String toEmail, String subject, String body){
try
{
MimeMessage msg = new MimeMessage(session);
//set message headers
msg.addHeader("Content-type", "text/HTML; charset=UTF-8");
msg.addHeader("format", "flowed");
msg.addHeader("Content-Transfer-Encoding", "8bit");
msg.setFrom(new InternetAddress("no_reply@example.com", "NoReply-JD"));
msg.setReplyTo(InternetAddress.parse("no_reply@example.com", false));
msg.setSubject(subject, "UTF-8");
msg.setText(body, "UTF-8");
msg.setSentDate(new Date());
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toEmail, false));
System.out.println("Message is ready");
Transport.send(msg);
System.out.println("EMail Sent Successfully!!");
}
catch (Exception e) {
e.printStackTrace();
}
}
}
Notice that I am setting some header properties in the MimeMessage, they are used by the email clients to properly render and display the email message. Rest of the program is simple and self understood.
Now let’s create our program to send email without authentication.
Send Mail in Java using SMTP without authentication
package com.journaldev.mail;
import java.util.Properties;
import javax.mail.Session;
public class SimpleEmail {
public static void main(String[] args) {
System.out.println("SimpleEmail Start");
String smtpHostServer = "smtp.example.com";
String emailID = "email_me@example.com";
Properties props = System.getProperties();
props.put("mail.smtp.host", smtpHostServer);
Session session = Session.getInstance(props, null);
EmailUtil.sendEmail(session, emailID,"SimpleEmail Testing Subject", "SimpleEmail Testing Body");
}
}
Notice that I am using Session.getInstance() to get the Session object by passing the Properties object. We need to set the mail.smtp.host property with the SMTP server host. If the SMTP server is not running on default port (25), then you will also need to set mail.smtp.port property. Just run this program with your no-authentication SMTP server and by setting recipient email id as your own email id and you will get the email in no time.
The program is simple to understand and works well, but in real life most of the SMTP servers use some sort of authentication such as TLS or SSL authentication. So we will now see how to create Session object for these authentication protocols.
Send Email in Java SMTP with TLS Authentication
package com.journaldev.mail;
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
public class TLSEmail {
/**
Outgoing Mail (SMTP) Server
requires TLS or SSL: smtp.gmail.com (use authentication)
Use Authentication: Yes
Port for TLS/STARTTLS: 587
*/
public static void main(String[] args) {
final String fromEmail = "myemailid@gmail.com"; //requires valid gmail id
final String password = "mypassword"; // correct password for gmail id
final String toEmail = "myemail@yahoo.com"; // can be any email id
System.out.println("TLSEmail Start");
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com"); //SMTP Host
props.put("mail.smtp.port", "587"); //TLS Port
props.put("mail.smtp.auth", "true"); //enable authentication
props.put("mail.smtp.starttls.enable", "true"); //enable STARTTLS
//create Authenticator object to pass in Session.getInstance argument
Authenticator auth = new Authenticator() {
//override the getPasswordAuthentication method
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(fromEmail, password);
}
};
Session session = Session.getInstance(props, auth);
EmailUtil.sendEmail(session, toEmail,"TLSEmail Testing Subject", "TLSEmail Testing Body");
}
}
Since I am using GMail SMTP server that is accessible to all, you can set the correct variables in above program and run for yourself. Believe me it works!! 🙂
Java SMTP Example with SSL Authentication
package com.journaldev.mail;
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
public class SSLEmail {
/**
Outgoing Mail (SMTP) Server
requires TLS or SSL: smtp.gmail.com (use authentication)
Use Authentication: Yes
Port for SSL: 465
*/
public static void main(String[] args) {
final String fromEmail = "myemailid@gmail.com"; //requires valid gmail id
final String password = "mypassword"; // correct password for gmail id
final String toEmail = "myemail@yahoo.com"; // can be any email id
System.out.println("SSLEmail Start");
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com"); //SMTP Host
props.put("mail.smtp.socketFactory.port", "465"); //SSL Port
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory"); //SSL Factory Class
props.put("mail.smtp.auth", "true"); //Enabling SMTP Authentication
props.put("mail.smtp.port", "465"); //SMTP Port
Authenticator auth = new Authenticator() {
//override the getPasswordAuthentication method
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(fromEmail, password);
}
};
Session session = Session.getDefaultInstance(props, auth);
System.out.println("Session created");
EmailUtil.sendEmail(session, toEmail,"SSLEmail Testing Subject", "SSLEmail Testing Body");
EmailUtil.sendAttachmentEmail(session, toEmail,"SSLEmail Testing Subject with Attachment", "SSLEmail Testing Body with Attachment");
EmailUtil.sendImageEmail(session, toEmail,"SSLEmail Testing Subject with Image", "SSLEmail Testing Body with Image");
}
}
The program is almost same as TLS authentication, just some properties are different. As you can see that I am calling some other methods from EmailUtil class to send attachment and image in email but I haven’t defined them yet. Actually I kept them to show later and keep it simple at start of the tutorial.
JavaMail Example – send mail in java with attachment
To send a file as attachment, we need to create an object of javax.mail.internet.MimeBodyPart and javax.mail.internet.MimeMultipart. First add the body part for the text message in the email and then use FileDataSource to attach the file in second part of the multipart body. The method looks like below.
/**
* Utility method to send email with attachment
* @param session
* @param toEmail
* @param subject
* @param body
*/
public static void sendAttachmentEmail(Session session, String toEmail, String subject, String body){
try{
MimeMessage msg = new MimeMessage(session);
msg.addHeader("Content-type", "text/HTML; charset=UTF-8");
msg.addHeader("format", "flowed");
msg.addHeader("Content-Transfer-Encoding", "8bit");
msg.setFrom(new InternetAddress("no_reply@example.com", "NoReply-JD"));
msg.setReplyTo(InternetAddress.parse("no_reply@example.com", false));
msg.setSubject(subject, "UTF-8");
msg.setSentDate(new Date());
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toEmail, false));
// Create the message body part
BodyPart messageBodyPart = new MimeBodyPart();
// Fill the message
messageBodyPart.setText(body);
// Create a multipart message for attachment
Multipart multipart = new MimeMultipart();
// Set text message part
multipart.addBodyPart(messageBodyPart);
// Second part is attachment
messageBodyPart = new MimeBodyPart();
String filename = "abc.txt";
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);
// Send the complete message parts
msg.setContent(multipart);
// Send message
Transport.send(msg);
System.out.println("EMail Sent Successfully with attachment!!");
}catch (MessagingException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
The program might look complex at first look but it’s simple, just create a body part for text message and another body part for attachment and then add them to the multipart. You can extend this method to attach multiple files too.
JavaMail example – send mail in java with image
Since we can create HTML body message, if the image file is located at some server location we can use img element to show them in the message. But sometimes we want to attach the image in the email and then use it in the email body itself. You must have seen so many emails that have image attachments and are also used in the email message.
The trick is to attach the image file like any other attachment and then set the Content-ID header for image file and then use the same content id in the email message body with <img src='cid:image_id'>.
/**
* Utility method to send image in email body
* @param session
* @param toEmail
* @param subject
* @param body
*/
public static void sendImageEmail(Session session, String toEmail, String subject, String body){
try{
MimeMessage msg = new MimeMessage(session);
msg.addHeader("Content-type", "text/HTML; charset=UTF-8");
msg.addHeader("format", "flowed");
msg.addHeader("Content-Transfer-Encoding", "8bit");
msg.setFrom(new InternetAddress("no_reply@example.com", "NoReply-JD"));
msg.setReplyTo(InternetAddress.parse("no_reply@example.com", false));
msg.setSubject(subject, "UTF-8");
msg.setSentDate(new Date());
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toEmail, false));
// Create the message body part
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText(body);
// Create a multipart message for attachment
Multipart multipart = new MimeMultipart();
// Set text message part
multipart.addBodyPart(messageBodyPart);
// Second part is image attachment
messageBodyPart = new MimeBodyPart();
String filename = "image.png";
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
//Trick is to add the content-id header here
messageBodyPart.setHeader("Content-ID", "image_id");
multipart.addBodyPart(messageBodyPart);
//third part for displaying image in the email body
messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent("<h1>Attached Image</h1>" +
"<img src='cid:image_id'>", "text/html");
multipart.addBodyPart(messageBodyPart);
//Set the multipart message to the email message
msg.setContent(multipart);
// Send message
Transport.send(msg);
System.out.println("EMail Sent Successfully with image!!");
}catch (MessagingException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
JavaMail API Troubleshooting Tips
java.net.UnknownHostExceptioncomes when your system is not able to resolve the IP address for the SMTP server, it might be wrong or not accessible from your network. For example, GMail SMTP server is smtp.gmail.com and if I use smtp.google.com, I will get this exception. If the hostname is correct, try to ping the server through command line to make sure it’s accessible from your system.pankaj@Pankaj:~/CODE$ ping smtp.gmail.com PING gmail-smtp-msa.l.google.com (74.125.129.108): 56 data bytes 64 bytes from 74.125.129.108: icmp_seq=0 ttl=46 time=38.308 ms 64 bytes from 74.125.129.108: icmp_seq=1 ttl=46 time=42.247 ms 64 bytes from 74.125.129.108: icmp_seq=2 ttl=46 time=38.164 ms 64 bytes from 74.125.129.108: icmp_seq=3 ttl=46 time=53.153 ms- If your program is stuck in Transport send() method call, check that SMTP port is correct. If it’s correct then use telnet to verify that it’s accessible from you machine, you will get output like below.
pankaj@Pankaj:~/CODE$ telnet smtp.gmail.com 587 Trying 2607:f8b0:400e:c02::6d... Connected to gmail-smtp-msa.l.google.com. Escape character is '^]'. 220 mx.google.com ESMTP sx8sm78485186pab.5 - gsmtp HELO 250 mx.google.com at your service
That’s all for JavaMail example to send mail in java using SMTP server with different authentication protocols, attachment and images. I hope it will solve all your needs for sending emails in java programs.
hi pankaj,
when i use this i’m getting – unable to find valid certification path to requested target,
can you help me with this
Hello Mstr @Pankaj , I would thank you first for this useful tutoriel , and ask you a queqtion if you don’t mind:

my code is working fine with local machine but when i host the website and my functionality it is not working. there is parsing issue at server side. I didn’t get the issue. please help!
This is a great start for developers new to emailing in Java, but dealing with javax JavaMail (nowadays migrated to Jakarta Mail) is very low level. Depending on your combination of needs (embedded images, attachments, iCalendar integration, forwarded email, replied-to email, alternative content) you need different Mime structures to have proper email behavior across email clients. You can explore all those structures here: https://www.simplejavamail.org/rfc-compliant.html#section-explore-multipart
Simple Java Mail (https://www.simplejavamail.org) is an open source library that manages these structures for you. It has a much simpler API and simplifies configuration for SSL/TLS connections. In addition, it adds tons of capabilities such as authenticated proxy, encryption, batch processing and much more.
People really shouldn’t be dealing with Mime objects anymore in this day and age. It’s an archaic system that is poorly described in terms of which structure to apply for which combination of needs. This includes most libraries such as Apache, Spring and JavaMail itself. Simple Java Mail solves this problem entirely free of cost.
hello using this code i am being able to send emails to only yaahoo acc. How will i be able to send mails to all acc?

Hi Pankaj,
How to add Test Results Status in the email body part or testng report.
Hi Pankaj,
In my piece of code I am using this line.
javax.mail.Transport.send(message);
The line is getting executed without any errors and emails are not sent, whereas in another class same piece of code exists but emails are sent appropriately.
Both the class are using the same method with same line of code [I have duplicated the method in these separate classes], yet it fails to send without errors.
Any insight is really appreciated.
Are you running both the classes on the same system, same user?
I have to send mass mail at once with addressing each mail recipient(“Hi username”) at other end except this rest all content is same . how i can do this. if i put in loop then it will create overehead on server.

Hi, I am trying to send an email from an java program to the ODC members. For that I need my company authentication. I have given the details they have asked but I don’t know the detail of service name. Kindly requesting you to give the detail of service name. So that I can proceed further.
hello sir ,
Sir i want send image in as a mail body using android ….
send “To” address may be gmail ,yahoo,outlook….
Why are we putting the properties above in the code:
Properties props = new Properties();
props.put(“mail.smtp.host”, “smtp.gmail.com”); //SMTP Host
props.put(“mail.smtp.socketFactory.port”, “465”); //SSL Port
props.put(“mail.smtp.socketFactory.class”,
“javax.net.ssl.SSLSocketFactory”); //SSL Factory Class
props.put(“mail.smtp.auth”, “true”); //Enabling SMTP Authentication
props.put(“mail.smtp.port”, “465”); //SMTP Port
where are we using it..?
Session session = Session.getInstance(props, auth);
Hi,
I am new to java, I am sending email using above code and facing error, can anybody tell me how to create javax.mail.Session object?
Thanks for such a useful and valuable article.
I wanted to know how to send an email with multiple attachments,should we use datasource multiple times or any other approach is there?
In above example to send image, we are attaching two files.
Hi Pankaj,
I went through your tutorial materials, even I am able to send the email successfully. But I have to incorporate the email delivery status whether the email has been sent successfully or not in the java code only, in other words we can say email is delivered or not so that I can pass that status to the other application.
Could you please let me know how I can apply such functionality? Although I have tried to implement such functionality using below approaches but nothing works for me.
1) smtpMsg.setNotifyOptions()
2) props.put(“mail.smtp.dsn.notify”, “SUCCESS,FAILURE,DELAY ORCPT=rfc822;XYZ@gmail.com”);
Thanks in advance

how can i resolve?? pls help me….
Sir,
In my project i have to send a mail when ever there is a work status changes.
I exectuted above mentioned program successfully. Even in the real time applications (spring mvc)
do we have to do the same??? Will expose the smtp server details like above? or any other way?
Could you please suggest how to implement this?
Thanks,
Mahesh
You can wrap the sending email logic in a web service and call it from your services, this will create orchestration and separation of concerns.
Hi Pankaj,

Whereas i can login with same username and password through webpage GUI.
Can you please tell me where is the problem and how to solve it ?
can we send more than one email address?
Thanks in advance.
Hi Pankaj,
When I use these codes in jsp I get the error Duplicate local variable session in line Session session = Session.getInstance(props, auth); here is the complete implementation,
Looking forward to hearing from you soon.
Thanks & Regards,
RJ.
Hi Ratan,
you get the error because in JSP there is already a variable named session. you should change the name of your variable to something else.
Actually you shouldn’t just paste this code in your JSP. Refactor it and write a function that you will just call in your jsp with parameters.
Regars,
Likide
The coding works perfect in java ,however I want to do this in JSP .
When I copy and paste these codes in JSP within
I get one error duplicate local variable session in the line
Session session = Session.getInstance(props, auth);

Im trying to implement your example, but i’m getting this error from gmail:

how can this implementation could be accomplish with your examples?

Hi pankaj,

Thankyou.
Hi,
I How to send mail to multiple user ??
Use toEmail to have comma separated email ids.
Hi Pankaj,
I need a favor from you.. Say for example i have multiple images in html content.
How do i add images in that instance.
Please help me.
Thanks in advance
Naresh T
You will use the same logic for each of the image. Note that
messageBodyPart.setHeader("Content-ID", "image_id");is only for the image. When you will add another image, just make this call again and use the cid value in the HTML code.Hi Pankaj,
Thanks for the reply.
I dont want to attach the images and refer from the CID.
I want to use a basic html content to send a mail so that i can refer the images from my webserver.
Do you have any idea. How to do that.
Coz i have done a POC. Thats absolutely working in OUTLOOK and YAHOO but not in GMAIL 🙁
Please help me.
Thanks in advance.
If its working in Outlook and Yahoo but not in GMail, it means that your code is fine but GMail is blocking the images. Do you see any option such as display external images etc.
how it will work in outlook i got the error:
