Send an Email Through the Amazon SES SMTP Interface with Java

This example uses the Eclipse IDE and the JavaMail API to send email through Amazon SES using the SMTP interface.

Before you perform the following procedure, complete the setup tasks described in Before You Begin with Amazon SES and Send an Email Through Amazon SES Using SMTP.


In this getting started tutorial, you send an email to yourself so that you can check to see if you received it. For further experimentation or load testing, use the Amazon SES mailbox simulator. Emails that you send to the mailbox simulator do not count toward your sending quota or your bounce and complaint rates. For more information, see Testing Amazon SES Email Sending.

To send an email using the Amazon SES SMTP interface with Java

  1. In a web browser, go to the JavaMail Github page. Under Downloads, choose javax.mail.jar to download the latest version of JavaMail.


    This tutorial requires JavaMail version 1.5 or later.

  2. Create a project in Eclipse by performing the following steps:

    1. Start Eclipse.

    2. In Eclipse, choose File, choose New, and then choose Java Project.

    3. In the Create a Java Project dialog box, type a project name and then choose Next.

    4. In the Java Settings dialog box, choose the Libraries tab.

    5. Choose Add External JARs.

    6. Browse to the folder in which you downloaded JavaMail. Choose the file javax.mail.jar, and then choose Open.

    7. In the Java Settings dialog box, choose Finish.

  3. In Eclipse, in the Package Explorer window, expand your project.

  4. Under your project, right-click the src directory, choose New, and then choose Class.

  5. In the New Java Class dialog box, in the Name field, type AmazonSESSample and then choose Finish.

  6. Replace the entire contents of with the following code:

    import java.util.Properties; import javax.mail.*; import javax.mail.internet.*; public class AmazonSESSample { static final String FROM = "SENDER@EXAMPLE.COM"; // Replace with your "From" address. This address must be verified. static final String TO = "RECIPIENT@EXAMPLE.COM"; // Replace with a "To" address. If your account is still in the // sandbox, this address must be verified. static final String BODY = "This email was sent through the Amazon SES SMTP interface by using Java."; static final String SUBJECT = "Amazon SES test (SMTP interface accessed using Java)"; // Supply your SMTP credentials below. Note that your SMTP credentials are different from your AWS credentials. static final String SMTP_USERNAME = "YOUR_SMTP_USERNAME"; // Replace with your SMTP username. static final String SMTP_PASSWORD = "YOUR_SMTP_PASSWORD"; // Replace with your SMTP password. // Amazon SES SMTP host name. This example uses the US West (Oregon) Region. static final String HOST = ""; // The port you will connect to on the Amazon SES SMTP endpoint. We are choosing port 25 because we will use // STARTTLS to encrypt the connection. static final int PORT = 25; public static void main(String[] args) throws Exception { // Create a Properties object to contain connection configuration information. Properties props = System.getProperties(); props.put("mail.transport.protocol", "smtps"); props.put("mail.smtp.port", PORT); // Set properties indicating that we want to use STARTTLS to encrypt the connection. // The SMTP session will begin on an unencrypted connection, and then the client // will issue a STARTTLS command to upgrade to an encrypted connection. props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); props.put("mail.smtp.starttls.required", "true"); // Create a Session object to represent a mail session with the specified properties. Session session = Session.getDefaultInstance(props); // Create a message with the specified information. MimeMessage msg = new MimeMessage(session); msg.setFrom(new InternetAddress(FROM)); msg.setRecipient(Message.RecipientType.TO, new InternetAddress(TO)); msg.setSubject(SUBJECT); msg.setContent(BODY,"text/plain"); // Create a transport. Transport transport = session.getTransport(); // Send the message. try { System.out.println("Attempting to send an email through the Amazon SES SMTP interface..."); // Connect to Amazon SES using the SMTP username and password you specified above. transport.connect(HOST, SMTP_USERNAME, SMTP_PASSWORD); // Send the email. transport.sendMessage(msg, msg.getAllRecipients()); System.out.println("Email sent!"); } catch (Exception ex) { System.out.println("The email was not sent."); System.out.println("Error message: " + ex.getMessage()); } finally { // Close and terminate the connection. transport.close(); } } }
  7. In, replace the following email addresses with your own values:


    The email addresses are case-sensitive. Make sure that the addresses are exactly the same as the ones you verified.

  8. In, replace the following SMTP credentials with the values that you obtained in Obtaining Your Amazon SES SMTP Credentials:


    Your SMTP credentials are different from your AWS credentials. For more information about credentials, see Using Credentials With Amazon SES.

    • YOUR_SMTP_USERNAME—Replace with your SMTP username credential. Note that your SMTP username credential is a 20-character string of letters and numbers, not an intelligible name.

    • YOUR_SMTP_PASSWORD—Replace with your SMTP password.

  9. (Optional) If you want to use an Amazon SES SMTP endpoint in a Region other than US West (Oregon), you need to change HOST in to the endpoint you want to use. For a list of Amazon SES endpoints, see Regions and Amazon SES.

  10. Save

  11. To build the project, choose Project and then choose Build Project. (If this option is disabled, then you may have automatic building enabled.)

  12. To start the program and send the email, choose Run and then choose Run again.

  13. Review the program's console output to verify that the sending was successful. (You should see "Email sent!")

  14. Sign into the email client of the recipient address. You will find the message that you sent.
