Learn to send emails using the Jakarta Mail API and using the Gmail SMTP Server. We will see the Java examples to send plain text emails as well as emails with attachments.
1. Gmail SMTP Server Details
Google has provided free access to one of its SMTP servers and we can use its Java code to send emails.
- Gmail SMTP server: smtp.gmail.com
- Port: 465 (SSL required) / 587 (TLS required)
- Username: Gmail id
- Password: The app password
We must create the app password as described in this guide. We cannot use the Gmail password (used to signin in the browser) if we have enabled the 2-factor authentication for the account.
In absense of App password, you will get the “AuthenticationFailedException: 534-5.7.9 Application-specific password required.” error in runtime.
2. Jakarta Mail API
For a typical client application, we need to perform the following steps to send an email:
- Create a mail message containing the message header and body
- Create a
Sessionobject, which authenticates the user using theAuthenticator, and controls access to the message store and transport. - Send the message to its recipient list.
3. Maven
Start with adding the following dependencies to the project. Note that the Angus Mail implementation of Jakarta Mail Specification 2.1+ providing a platform-independent and protocol-independent framework to build mail and messaging applications.
<dependency>
<groupId>jakarta.mail</groupId>
<artifactId>jakarta.mail-api</artifactId>
<version>2.1.2</version>
</dependency>
<dependency>
<groupId>org.eclipse.angus</groupId>
<artifactId>jakarta.mail</artifactId>
<version>2.0.1</version>
</dependency>4. Send an Email with TLS
The EmailSender is a utility class that accepts the message parameters and sends the email to recipients.
import jakarta.mail.Authenticator;
import jakarta.mail.Message;
import jakarta.mail.MessagingException;
import jakarta.mail.Multipart;
import jakarta.mail.PasswordAuthentication;
import jakarta.mail.Session;
import jakarta.mail.Transport;
import jakarta.mail.internet.InternetAddress;
import jakarta.mail.internet.MimeBodyPart;
import jakarta.mail.internet.MimeMessage;
import jakarta.mail.internet.MimeMultipart;
import java.util.Date;
import java.util.List;
import java.util.Properties;
public class EmailSender {
private static final Properties PROPERTIES = new Properties();
private static final String USERNAME = "admin@gmail.in"; //change it
private static final String PASSWORD = "password"; //change it
private static final String HOST = "smtp.gmail.com";
static {
PROPERTIES.put("mail.smtp.host", "smtp.gmail.com");
PROPERTIES.put("mail.smtp.port", "587");
PROPERTIES.put("mail.smtp.auth", "true");
PROPERTIES.put("mail.smtp.starttls.enable", "true");
}
public static void sendPlainTextEmail(String from, String to, String subject, List<String> messages, boolean debug) {
Authenticator authenticator = new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(USERNAME, PASSWORD);
}
};
Session session = Session.getInstance(PROPERTIES, authenticator);
session.setDebug(debug);
try {
// create a message with headers
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject(subject);
msg.setSentDate(new Date());
// create message body
Multipart mp = new MimeMultipart();
for (String message : messages) {
MimeBodyPart mbp = new MimeBodyPart();
mbp.setText(message, "us-ascii");
mp.addBodyPart(mbp);
}
msg.setContent(mp);
// send the message
Transport.send(msg);
} catch (MessagingException mex) {
mex.printStackTrace();
Exception ex = null;
if ((ex = mex.getNextException()) != null) {
ex.printStackTrace();
}
}
}
}To test the above class, we can invoke the sendPlainTextEmail() method as follows:
import java.util.List;
public class MailTest {
public static void main(String[] args) {
EmailSender.sendPlainTextEmail("sender@gmail.com",
"reciever@gmail.com",
"Test Email",
List.of("Hello", "World"),
true);
}
}Check the email. You should be able to see the email in your Gmail inbox as follows:
5. Send an Email with SSL
If we do not have TLS support on the server, we can use the SSL support provided in the API. To use SSL, follow these steps:
- Remove the
mail.smtp.starttls.enableproperty - Use port number 465
- Add SSL support in the properties
The modified properties will be:
static {
PROPERTIES.put("mail.smtp.host", "smtp.gmail.com");
PROPERTIES.put("mail.smtp.port", "465");
PROPERTIES.put("mail.smtp.auth", "true");
PROPERTIES.put("mail.smtp.socketFactory.port", "465");
PROPERTIES.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
}Now we can run the above program with modified properties, and we will again get the email in our inbox.
6. Adding Email Attachments
If we want to add the attachments to the email body, we can use the MimeBodyPart.attachFile() method to attach a file.
MimeBodyPart attachmentBodyPart = new MimeBodyPart();
attachmentBodyPart.attachFile(new File("path/to/file"));7. Conclusion
In this example, we saw the Java programs to send emails using the Gmail SMTP server to multiple recipients. Drop me your questions in the comments.
Happy Learning !!
Hello everyone, could you pls help to send an email using the above code. I am unable to send emails through the above code. Getting following error message. Thanks

If you have enabled 2-factor authentication on your Google account you can’t use your regular password to access Gmail programmatically. You need to generate an app-specific password and use that in place of your actual password.
Steps:
Log in to your Google account Go to My Account > Sign-in & Security > App Passwords (Sign in again to confirm it’s you) Scroll down to Select App (in the Password & sign-in method box) and choose Other (custom name) Give this app password a name, e.g. “mailer” Choose to Generate Copy the long generated password and paste it into your code instead of your actual Gmail password.
Reference: SO Thread
someone help me i cannot resolve this exception as i’m new to this mail service and just copied the code and run it
change smtp port from 586 to 587
You need to connect to your network team regarding this they will give u access on your system to access the there host without any network restrictions.

Find out the IP address of mail server i.e. “blr-outlook.ibm.com” and place that IP directly into “props.put(“mail.smtp.host”, host);”
Hi,
Sorry to say sir,but message does not send in email ids.this code used in my personal machine but that is not even running.Please help me.I’ve used editor NetBeans 7.2.and i’m sending my debug after run.

This code works buddy. Just your machine is not able to resolve hostname. Open windows command prompt. Type “ping blr-outlook.ibm.com”. See if machine is reachable. I believe it will not and will timeout. If you can ping above from command prompt, then ONLY this code will run.
Hi,
Finally my code is mention below.I don’t know why is not message send in email ids.
Please check my code and find my mistake and correct them.I check “ping blr-outlook.ibm.com” in cmd.
I saw in cmd after enter this blah blah..
Thanks

In your catch block, before returning false, plz print/log the error as well.
catch (Exception mex)
{
mex.printStackTrace(); //OR Log it

It will show you why mail is not sent.
Hi Lokesh,
I have been facing an issue with javamail sending a mail from gmail. Actually i need to send it from an smtp server starting with 10.x.x.x using port 25. My Environment is jdk 1.7/windows7 32bit/javamail 1.4.1.
Sample Code
String to = "foo@bar.com";//change accordingly // Sender's email ID needs to be mentioned String from = "example@gmail.com";//change accordingly // Assuming you are sending email through relay.jangosmtp.net String host = "10.x.x.x"; Properties props = new Properties(); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); props.put("mail.smtp.host", host); props.put("mail.smtp.port", "25"); props.put("mail.debug","true"); // Get the Session object. Session session = Session.getInstance(props, new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } }); try { // Create a default MimeMessage object. Message message = new MimeMessage(session); // Set From: header field of the header. message.setFrom(new InternetAddress(from)); // Set To: header field of the header. message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to)); // Set Subject: header field message.setSubject("Testing Subject"); // Now set the actual message message.setText("Hello,"); // Send message Transport.send(message); System.out.println("Sent message successfully...."); } catch (MessagingException e) { throw new RuntimeException(e); } }java.lang.RuntimeException: javax.mail.MessagingException: Could not connect to SMTP host: 10.x.x.x, port: 25;
nested exception is:

what port number should i use ??
emailProperties.put(“mail.smtp.port”, “586”);
586 port number gives error.
Manjeet, Can you please tell me the exact error [stack trace].. FYI: above program runs fine on my home network.
Also, please ensure two things before running this program.
1) You are not behind any firewall. [Most corporate networks have them. e.g. in offices]
2) Put correct credentials here: [i.e. your email and password]
String fromUser = “user-email@gmail.com”;
String fromUserEmailPassword = “*******”;
